Baked Steel Cut Oatmeal

This baked steel cut oatmeal is one of my all-time favorite recipes. The whole thing can be assembled the night before and popped in the oven the following morning. Or it can be assembled and baked immediately. It is infinitely customizable to your preferences — you can make it dairy-free, vegan, with or without nuts, and with any fruit your heart desires 🙂
Yesterday, while three movers packed away our lives into boxes, I snuck one last dish into the oven, a mixture of steel cut oats, cinnamon, maple syrup, and coarsely chopped almonds, a dish I have been addicted to in some form or another since March.
For months, I made this baked oatmeal using rolled oats and, as suggested, always mixed up the dry ingredients the night before baking, which allowed for easy preparations in the morning. But about a month ago I discovered that when steel cut oats replace the rolled oats, the morning effort disappears altogether: the entire dish — egg, milk, melted butter, baking powder and all — can be assembled the night before baking.
I love this oatmeal. When it bakes, the mixture separates into distinct layers, the nuts forming a crisp-like topping, the berries bobbing underneath, the creamy oats and custard forming the foundation. The steel cut oats, flavored with cinnamon and maple, remain firm and chewy, which along with the nuts offer the loveliest texture throughout. I could eat the whole pan in one sitting.
I love these oats with berries. I love them without. I love them freshly baked. I love them cold, straight from the fridge. I like them with walnuts. I love them with almonds. I could eat them at every meal. I like them so much that when Ben tells me he can’t make it home for dinner, I think, “Yes, I get to eat my oats!” And while these oats are the perfect kind of thing to make for a crowd, at the moment I’m not at all upset that my children don’t like them. This is the kind of dish I hope so very much you will all whisk up tonight before hitting the hay, so you, too, have something to savor, with friends or without, all Saturday morning long.

Description
Inspired by Heidi Swanson’s recipe in Super Natural Every Day via Orangette
I like my Pyrex 8-inch square baking dish for this one. You can also use six 6-oz ramekins.
If you are mixing this at night and baking in the morning, follow the recipe through step 2, omitting the fruit. Store mixture in baking vessel or in a Tupperware. In the morning, give the mixture a stir. Scatter berries (if using) into an 8-inch baking dish. Pour milk-oat mixture over the berries; then proceed with recipe.
As I noted, I like these baked oats both with berries or other fruit and without, so don’t hesitate to make them if you don’t have any berries on hand — they are so good on their own. I have used both almonds and walnuts. I do toast the walnuts. I don’t toast the almonds — it doesn’t seem to matter. The mixture can be assembled the night before, though it doesn’t have to be.
Update, Oct 2014: Almonds are my preference. Peeled, sliced apples are also my preference. I omit the cinnamon. I also now do 1/4 cup maple syrup as opposed to 1/3 cup.
If you are making individual portions, I think the easiest method is this: mix dry ingredients as instructed in step 1; spoon about three tablespoon of the dry ingredients into six 6-oz ramekins; then pour liquid over top. The liquid will reach the top of each ramekin. To prevent a catastrophe, I suggest lining a 9×13-inch baking dish with parchment paper and placing the filled ramekins in the dish to bake.
Ingredients
- 3/4 cup steel cut oatmeal
- ½ cup (60 g) almonds (sliced, untoasted are great) or walnuts halves, toasted and chopped
- 1 teaspoon baking powder
- 1½ teaspoons ground cinnamon, optional
- ½ teaspoon fine sea salt or kosher salt
- ¾ to 1 ½ cups (90 to 185 g) blueberries, optional—I like using 1 peeled, sliced apple
- 2 cups (475 ml) milk, 2% or whole
- 1/4 to 1/3 cup (80 ml) maple syrup, I find 1/4 cup to be sweet enough
- 1 large egg
- 3 tablespoons (45 grams) unsalted butter, melted and cooled slightly
- 2 teaspoons vanilla extract
Instructions
- See notes if you are refrigerating this overnight. Otherwise, preheat the oven to 375ºF. In an 8- or 9-inch baking pan, mix together the oats, the nuts, baking powder, cinnamon, if using, and salt. Place the sliced apples or berries on top.
- In a medium bowl, whisk together the milk, maple syrup, egg, butter, and vanilla. Pour the milk mixture over the oat mixture, and shake the pan to distribute.
- Transfer pan to the oven and bake for 55 to 60 minutes (Note: Several commenters have had issues with browning too quickly, so I advise checking after 30 minutes, and if it looks as though it is browning quickly, turn oven down to 350 and check periodically for doneness), or until the top is golden and the oat mixture has set. Remove from the oven, and allow to cool for a few minutes before serving.

Love this! I used blueberries and chopped pecans. Salted butter was all I had so simply left out the salt. I like mine a little sweeter so next time I’ll use third cup of maple syrup though I’ll still probably sprinkle brown sugar on top before eating. The amazing thing is my husband ate 2 bowls of it! He likes it with milk and brown sugar before eating.
So great to hear this, Lisa! Love the idea of serving it with milk and brown sugar … just how I ate it when I was a kid!
Alexandra, I have returned to make this delicious recipe, again. I’m wondering how I would adapt the recipe if I added farro, perhaps millet, and steel cut oats?
I’m planning on taking it with me on a road trip to catch migrating shorebirds: only my favorite foods along for the trip! Thank you!
Hi Judy! It’s so hard to say. I would imagine if you used the same total quantity of grain (3/4 cup), you wouldn’t need to make any other changes — I think farro and millet would cook in the same amount of time as the steel cut oats. I can’t say for sure bc I haven’t tried, and it might take some trial and error to get right.
Enjoy your trip! Fun!
Thanks, Alexandra! I’ll give it a try. I know farro takes longer to cook but I think the steel cut will hold up well. I’ll let you know if my results are worth reporting! LOL
Hi, Alexandra,
Reporting back on my use of farro and steel cut oats. It worked well! I only used 1/4 c. farro in case it didn’t cook to a tender point. But it did!
Thanks for your encouragement to try it.
Oh yay! Great to hear this, Judy! Thanks for reporting back 🙂
I hadn’t made this for awhile and have forgotten how good it is! I cut back the maple syrup even more than Alexandra to 1/8 cup, which for me is plenty sweet. I also baked the oatmeal at 350 for an hour and had no problems with browning too quickly. Mixing the oats the night before may seem like a nuisance, but in the morning, it’s wonderful to be able to slice the apple and pop the dish into the oven. I used a scant cup of steel cut oats, which gives the dish a slightly more custardy texture. When serving, I like to pour a little milk into the bowl, but my husband likes his as is. Cream would be nice 🙂
We loved this recipe, thank you! I think I will try incorporating rhubarb in it! Have you ever tried that? I’m thinking I would probably need a little extra maple syrup.
Oh I love this idea! Just had a rhubarb crisp last night … so good. Yes, I think a little extra maple syrup sounds like a good idea to balance out the tartness of the rhubarb.
Hi Alexandra,
I love this recipe so much that I’ve made it many times over the last couple of months. Thanks for the great recipe, Alexandra!! I want to try making a chocolate, raspberry version next and was curious if you have any suggestions for the amount of of cocoa powder I should add. 🙂
Thanks!
So great to hear this Chathu! Chocolate-raspberry sounds amazing. Regarding cocoa powder … I’m not sure! I would maybe start with a tablespoon or two? It might take some trial and error to get right. Let me know if you make any discoveries 🙂
Reporting back – I made a chocolate, berry, and hazelnut version. It turned out great! as you suggested, I added 1 tbsp of cocoa powder, some strawberries and blueberries, and topped it with chopped hazelnuts. It really was a good combo. Thanks!!
Oh yay! Great to hear this, Chathu! Can’t wait to try it myself 🙂 🙂 🙂
It would be helpful if you posted ONE picture, and the recipe.
I find it annoying to wade through tons of unneeded photos to get to the details.
If you don’t want to scroll through all the text and pics, you can jump to the recipe. There’s a button at the top you can click which will take you straight to a printable version of the recipe.
Thank you, Kari 🙂 🙂 🙂
This is delicious! I usually don’t leave comments but this recipe is comment worthy! My husband loved it, thought it was dessert and suggested putting icecream on it 🙃 I followed the recipe, using blueberries wand slivered almonds, plus coconut as my additions. Can’t wait to try the apple version. Thank you!!
Wonderful to hear this, Karen! It totally could pass as dessert 🙂 🙂 🙂
Absolutely love this recipe.
Great to hear, Sally!
Do you think I could substitute almond milk for the whole or 2% milk?
Yes!
Theeee best. I absolutely love this stuff. Assembled the whole thing the night before, fruit and all before reading your directions on how to do it overnight. Ha. O well I am fully confident this batch will still be good
So great to hear this, Suzy! I think there are many ways to go about making it ahead of time … I’m sure your method was perfect (and it sounds easier than mine). Thanks for writing 🙂 🙂 🙂
How important is the baking powder? Can I omit it if I don’t have any on hand? Clearly not a baker.
The texture will just be a little denser, but it will be fine … go for it 🙂
I’ve tried out a lot of oatmeal bake recipes on the internet and keep coming back to this one. So good! Thank you
So nice to hear this, Kendra! Thanks for writing 🙂 🙂 🙂
Loved this breakfast dish! I made the overnight version. Forgot to mix ingredients separately – turned out great. Also did not have maple syrup – substituted 1/4 cup honey instead and worked well (would not use more than 1/4 cup). I also used frozen blueberries. Put them in the fridge to thaw while the dish was in the fridge overnight. Expect that’s not needed but I did not want to lower them temp more than needed. Baked at 350 for 50 min – came out perfect! Will definitely make this again. Served with 1/4 cup cold milk poured over.
So nice to hear all of this, Maggie! Thanks so much for writing and sharing all of these notes. I love blueberries in this one, too.
Delicious! My husband and I are watching our cholesterol and trying to incorporate oatmeal into our diet. Neither one of us are huge oatmeal fans but have been trying some recipes out. This was delicious! We made your favorite with the blueberries and almonds but I put cinnamon in as well. Will definitely make this again!! Thanks for sharing!
So great to hear this, Nancy! I have been making it with cinnamon recently, too… something about this time of year I think 🙂 Thanks so much for writing!
Re: Baked Steel Cut Oats – OH MY GOSH I LOVED THIS! I rarely leave a comment after cooking something but this is worthy. I made it with a chopped apple, no blueberries. It is so good. I was worried it would be too sweet, but 1/4 cup of maple syrup is perfect. I threw in a handful of golden raisins as well. Used slivered almonds because that’s what I had. It baked in 50 minutes, no overbrowning. I served it with a bit of heavy cream. Decadent. Next time I think I might use 2 apples instead of 1. I’ll def be making this again.
So wonderful to hear this, Ardis! Thanks so much for writing and for sharing all of your notes. Love the idea of adding golden raisins here AND serving it with heavy cream. Yum.
OMMMMMMMG! Very 1st time making a baked oatmeal, ( and I’m 61!)received your recipe yesterday and knew I had to try it. All I can say is wow, wow, wow its 35 degrees on Long Island this morning and this cooking( with the cinnamon, blueberries and almonds) had the house smelling absolutely fabulous.!🥰🥰. We topped it with a scant bit of brown sugar and some cold 2% milk. Warmed our hearts as well as our souls. Thanks Ali for another great recipe, sorry I waited so many years to try, but happy I waited for yours!
Awwww Arlene 🙂 🙂 🙂 So nice to hear this. Love the idea of brown sugar + cold milk… totally brings me back to oatmeal bowls of my youth! So glad you liked this one. Thanks for writing!
Too eggy for me! Both in flavor and texture—the egg collected in places (most the top) and formed a curd-like, custardy layer. Not appetizing. I followed the directions exactly, using apples, almonds, and a combination of whole and 2% milk.
I realized that I like this idea, but I don’t need my baked oatmeal to set. I’m eager to try this again, but without the egg.
I bought quick cooking (3 Minute) steel cut oats by mistake. Could I use them? Perhaps adjust baking time or would apples not cook? Thank you!
Hi Mary! I think yes, you should probably shorten the cooking time briefly — maybe 35 minutes? The original recipe that uses rolled oats calls for 2 cups of oats and 35 minutes of baking, so I’m thinking 35 minutes is probably about right, and I think the apples will be fine.
Made it for a hockey tournament morning. Would you have the nutritional information? Our daughter is a Type 1 Diabetic and carb counts are needed. I haven’t been able to locate it on the page. Thanks.
Oh how fun! I do not have the nutritional information for recipes on my site unfortunately. I do love this website for calculating that information, however: https://www.verywellfit.com/recipe-nutrition-analyzer-4157076
Hi!
I made this delicious recipe, but altered it so it was VEGAN. YUM! I used almond milk, a flax egg, and earth balance to replace all dairy ingredients. I’m currently eating my second serving of the morning. Love your recipes, especially when I can easily adapt to vegan! Thanks!
So nice to hear this, Katie! Thanks so much for writing and sharing your notes. So glad the flax egg worked, and thank you for your kind words 🙂 🙂 🙂
Hi Katie! I would like to make a vegan version too. May I ask for the measurements you used to make a flax egg? Thank you!
I really want to make the baked steel oats but am hoping to leave out the butter for health reasons. Would you recommend I replace with oil (like avocado) or should I just leave the butter out without substituting?
Hi Sol! I think you could just leave the butter out and still have great results.
OH MY GOODNESS!! Woke up to a snow day and needed breakfast, this was fantastic! I also used the apple, substituted applesauce for the egg but kept the maple syrup at 1/4 cup so not too sweet. I luuuuuv steel cut oats so this was right up my alley! Shared recipe with friends and will definitely make again myself!!
So wonderful to hear this, Kim! Thanks so much for writing and sharing your notes. HNY 🎉
I’d like to make for a large crowd using a 9×13 pyrex. Could I double this recipe or if not, what adjustments would you make?
Hi Kathleen! Yes, double the recipe. I wouldn’t make any other changes. It might need a bit more time in the oven, but just keep an eye on it.
Everyone in my home loved this. Healthy and so easy to make. Will make often. Thanks so much for sharing.
Great to hear, Jan! Thanks so much for writing 🙂 🙂 🙂
When I checked it at 28 mins it was nearly burnt. It’s a bit over toasted and set softly but the flavors are beautiful. Instead of spices and nuts, I used rose extract, dash of cardamom, and just a teaspoon of dried lavender. I also added another egg (I love eggy oatmeal) 🥚 ❤️
I had lots of homemade jam (lower sugar than shop bought) from the Summer but I’m trying to reduce my bread intake. I found baked oatmeal by accident last week, and I loved that your recipe all ready uses less maple syrup and 1 egg so it would set up (my old recipe uses 1/2 cup maple syrup and 2 eggs which made a lightly sweetened egg custard which I enjoyed but wanted a different base for my PB and jam). I have a sweet tooth (and enjoy 1/2 cup maple syrup), but found 1/4 cup maple syrup didn’t made a ‘savoury’ oatmeal, so I would try 1/3 cup next time without sweet toppings.
Anyway my modifications:
– I swapped steel cut oats for 240g (2 1/2 cups packed roughly) whole oats because that’s the texture I’m used to (would love to try steel cut when I have space in the fridge/plan ahead)
– Omitted almonds and fruit so I had a plain base for toppings (nut butter, whole nuts/seeds, jam or compote or sliced banana). Forgot the vanilla extract! But the maple and cinnamon gave enough flavour
– I used 1tsp ground cinnamon for subtle spice.
– I reduced the almond milk to 1 3/4 cups (420ml) (not DF, just for flavour) so I could add 1/3 cup/75g dairy Greek yoghurt for extra protein (and less waste).
– I used 1 1/2 medium eggs (75g) – again for extra protein and to work out the limit for egg flavour – this amount didn’t give me eggy flavour custard.
– Kept baking powder, salt (I used cheap table lol) and butter the same.
Thanks again!
Oh forgot to mention, I used 350F (converted from Celsius) for 30 minutes. I obviously didn’t get any burning, but wanted to mention as a solution to the problems mentioned above – you will still get toasted nuts (nuts toast at 320F for 10-15 minutes) 🙂
So great to hear all of this! Thanks so much for taking the time to write and to share such detailed notes. So helpful for everyone!
Easy, delicious! but note without nuts and fruit, this is barely 4 servings. We like leftover oats, so I’d double. 1/4 cup maple syrup was plenty, almond milk worked well, butter not necessary, baked at 350 for 60 minutes while everyone else slept in.
Delicious and so much easier than standing over the stove stirring twice a week!
I’ve just made this for the second time — in the oven now. I’m attempting to adapt it to a two-serving version. I probably should’ve reached out with my questions prior to my second try. Oh well.
The recipe says that the overnight soak is optional, but I thought steel cut oats required soaking. When using the overnight soak, how is it ok for the baking powder to be mixed with the liquid that far ahead? I thought baking powder activated as soon as it got wet.
Hi Jennifer! Great to hear this 🙂
Regarding your questions: Steel cut oats do not need to be soaked. And it’s baking soda that activates shortly after being mixed with liquids. Let me know if there’s anything else!
Thanks for the info.
I think I’ve decided to start baking it without fruit and serving berries on top, so I can now prep it the night before right in the loaf pan I bake it in! That will definitely make it worthwhile and timesaving to mix it up the night before.
Hi, Alexandra,
Even with the butter in the recipe, I find I need to butter my baking pan. But I have perfected my prep ahead protocol thusly: put dry ingredients into a small mason jar whenever (I do two or three at a time), then mix wet ingredients in a shaker container and set out the baking pan with a pat of butter in it the night before. In the morning, I turn the toaster oven on to preheat and by the time I’ve buttered the pan and layered in the ingredients, the oven is ready!
Great to hear Jennifer! Buttering the pan is a great idea 🙂 Thanks so much for writing and sharing your notes. Love the streamlined process!
Really delicious, my husband loved it. Were dairy free so I used coconut oil and oat milk, it was great. I also subbed frozen mangos and strawberries once which was amazing too!
Oh yum! That all sounds amazing Aynsley 🙂 🙂 🙂
And it’s now on repeat! Have shared this recipe far and wide, it’s a real keeper.
Thanks for such an amazing breakfast, anytime of the day or night, treat.
Great to hear, Susan! Thanks so much for writing. And I agree: I love these oats at ALL times of day 🙂
My family absolutely loves this recipe. We doubled the blueberries and cut the syrup in half.
Great to hear, Tex! Thanks so much for writing and sharing your notes — love this idea.
