Easy Lemon Blueberry Crisp

Several months ago I watched Dorie Greenspan make madeleines on the Martha Stewart Show. While the madeleines looked divine, what struck me most from her demonstration was her handling of the lemon zest. Rather than whisk the zest directly into the dry ingredients, she placed it in a small bowl with the sugar and massaged the two ingredients together with her fingertips until she had created a moist and fragrant citrus sugar, a technique, she says, that serves to release oils from the zest into the sugar, making the lemon flavor twice as pronounced.
I still haven’t made the madeleines, but, when I remember to, I employ this citrus-sugar technique when appropriate when I’m baking. While it’s not critical — freshly grated zest, massaged into sugar or not, always adds a nice flavor — I have found that the technique does heighten the citrus flavor, which is especially nice in cakes and muffins and cobblers. Moreover, making the citrus sugar is kind of fun. Try it. It smells so good! And it makes just about the best fresh squeezed lemonade you could ever imagine.
The most recent dish I’ve given the citrus-sugar treatment to is my mother’s blueberry crisp, one of my favorites. Like most crisps, this one takes no time to prepare, and if you have a food processor, the topping — a mixture of flour, sugar, almonds and butter — comes together in seconds. The absence of oats and brown sugar in this crisp topping makes it particularly light and allows the lemon-sugared blueberries to really shine.

oh yum, this looks really good. I remember seeing/employing the lemon & sugar trick, but now I can’t remember what I was making. You’re right though, why not just do it whenever lemon & sugar are involved – great idea. Perhaps I’ll make this for a little impromptu “4th-from-afar” gathering. Happy crisp eating and fireworks watching!
What a great technique. I must remember that. For 4th of July I plan to make a cornmeal crust blueberry pie, but your crisp looks appealing as well.
I learned about zesting in sugar from Dorrie’s cookbook and it changed everything for me in baking. The crisp looks perfect with the lemon and almonds, which all combines so well.
I tried a lemon roll recipe from thekitchn and it used the sugar and lemon zest technique. I can’t wait to try it in this crisp! Happy 4th!
I have made it, and I declare it to be super simple and BEYOND delicious! I used a little less blueberries because I am cheap and didn’t want to buy more…but it turned out fabulous. But I fear for the clean up… was I supposed to spray the pan with pam or something? Oopsies! I also fear for my weight as I will likely eat 3/4 of the pan for dinner tonight. Once again Ali, you and your recipes have filled our home with joy (I also made your cornbread last night! when will the caloric intake end??)
Katykat, I love you. So happy to hear that you made this! The cleanup shouldn’t be too bad. Maybe let it soak. I never spray the pan with anything. And when im really feeling lazy, I throw the whole pan in the dishwasher. Miss you chica!!
Just when I was wondering what to do with all the blueberries, another fabulous Alexandra recipe!
Thanks,
Diana
Try mixing the zest and sugar with lavender sometime (for shortbread, etc.) – it’s lovely, as well.
Donna, that sounds awesome! Next time I make shortbread, lavender it will be!
Just picked fresh blueberries and threw this crisp together so quickly! Thanks Ali! You’ve made our 4th of July extra sweet!
Smells fantastic!
Awwww 🙂 🙂 🙂 So nice to hear this, Janine! Thanks for writing.
If I have a almond allergy, is there a good substitute or can I just skip it?? Looks amazing. Thanks!
Hey Jess, I think you could leave out the almonds but you might miss a bit of that crunch. I used to love this recipe, but I haven’t made it in ages. It’s a crostada recipe that calls for cornmeal in the crisp topping: https://alexandracooks.com/2007/08/05/nectarine-and-blackberry-crisp/
You could try that or just sub in cornmeal for the almonds in this crisp recipe. Good luck with it!
Consider pecans or any nut you know you are not allergic to such as hazelnut
Thanks Lisa!
I made this for the fourth of july. It was beyond delicious. the lemon rind sugar trick is so awesome. I will try it with different fruit also. thanks
Leslie — so happy to hear this!
This makes the best blueberry crisp I’ve ever tasted! I divided the recipe into 3 smaller baking dishes to give to friends and it worked perfectly. I had just U-Picked 8 lbs. of blueberries, maybe that has something to do with the delightful almost floral taste. Blueberries have such a mild flavor my Mom always added huckleberries to give a little zing….. but the lemon/sugar mixture makes a perfect balance of tart/sweet. The almonds are the perfect final touch. Excellent, excellent. A real keeper…. a forever favorite.
PS I must confess I almost ate an entire crisp (the smaller of the 3) before it cooled…. just to make sure it tasted that good! If I’d had ice cream on hand the whole thing would have been gone!
D.L. Gillan — I am so happy to hear this! I am glad you share the enthusiasm for the recipe. I have tried so many crisp recipes, and they are always good, but there is something about the simplicity of this crisp topping that I think really sets it apart. Also, I have been known to polish off blueberry crisp by the half-pan… it’s hard to not just tuck in when it’s sitting out on the counter. THanks for writing in!
HI Ali! I am going up to Little Compton, RI this weekend with a few friends and staying at a friend’s house her parents rented. I am going to make this Blueberry Lemon Crisp tonight and it will be making the trip with me… a perfect weekend hosting gift that all can enjoy. Thank you! xoxo
Anne, so much fun! I wish I were headed to RI with you! My aunt and uncle have a house there and growing up, we would always spend a week there in the summer. I hope your friends enjoy the crisp!
The Lemon Blueberry Crisp is in the oven! I can’t wait to try it! Thanks for sharing such a great recipe.
totally awesome
Ann — So happy to hear this!
I don’t keep sliced almonds on hand, but I always have whole almonds. Could I use them instead?
Yes! I would coarsely chop them in food processor or place them in a ziplock and crush them with a rolling pin to break them up a bit.
Made this last night for our Valentine Day dinner. Cut recipe in half and was a perfect amount and oh so delicious! Thank you again for ANOTHER amazing, easy to follow directions thing to make!
So happy to hear this, Cindy!! And it is my absolute pleasure 🙂 🙂 🙂
Good day. Can you substitute frozen blueberries? If so, how many cups?
Yes! Same amount: 6 cups.
Have you ever made this with other berries or a mix? Looks delicious!
Beth, I have not, but I think it would be absolutely delicious with other berries mixed in.
Alexandra, thank you so much for a fantastic and SUPER easy summer dessert! We love blueberries and gobbled this up (for breakfast :)).
Wonderful to hear this, Hina! Hope you are well 💕💕💕
Could I use almond flour instead of all purpose flour since I need this gluten free?
Much difference in texture and taste? Have made it with flour and LOVE it!
Thanks
Hi Cindy! I think you probably could, but keep in mind the crisp topping likely will be a little more crumbly due to the lack of gluten. Let me know if you give it a try!
Hello Ali,
I can’t find decent fresh blueberries this time of year. I read below that subbing frozen is ok. Should I proceed with the berries frozen or defrost first. I have read a difference of thought on this when googling that question.
If any of your readers have actually used frozen I would love to hear how they did it and if they were pleased with results. Thank you.
Hi Denise! I think frozen will work great. And I don’t think you need to thaw them first. I never thaw them when I use them in other recipes. That said, if you are worried, I would thaw and drain them first. Can’t hurt!
Thank you, good idea, I am still trying for fresh though. I found some raspberries and blackberries this morning, I will mix with whatever blueberries I end up with.
I’ll do a
Tri-berry easy crisp!
Yum! That sounds amazing 🙂
This was delicious! FYI-I did not have sliced almonds, so I used almond flour. So yummy 🙂
So great to hear this!! Thanks so much for writing. I love a crisp … low effort, big reward. Great to hear almond flour worked, too! Smart.
This is the BEST blueberry dessert that I have ever tasted!! The lemon sugar really makes the flavor pop. So easy and elegant. Made it for my dog club and everyone loved it. Thank you so much!!!
So wonderful to hear this, Doran! Thanks so much for writing 🙂 🙂 🙂
Can I use frozen blueberries?
I saw above that someone had asked this and the answer is ‘yes’. I’m just wondering if the baking time needs to be increased.
You shouldn’t have to increase the time — you’ll know to take it out when the topping is evenly golden. The blueberries will be bubbling, too.
Yes!
Hello, I am hoping you can help. I made this tonight and while the flavors are great, my blueberries released a lot of liquid and didn’t set at all. I baked it for about 28 minutes. I covered it for the last few b/c the topping was getting too dark. Any suggestions?
Thanks and I love your recipes!
Hi Laura! I’m not sure how to advise. What material pan did you use? Did you make any other changes? Next time, you could add a tablespoon or two of flour to the berries… that would help them set up.
Oh thanks so much for the quick reply! I used a glass plan. I did x1.5 the topping but I wouldn’t think that would effect the berries. Next time I will add some flour.
Laura
Beginning baker here. Do I use roasted, salted almonds or raw almonds? Thank you!
Hi Susan! Raw almonds are best!
I made this today and it came out perfectly. The crisp topping is amazing! But I found it a bit too sweet. Could I omit the sugar from the blueberries and just leave it in the crisp topping? Or do they need the sugar for the consistency? Thanks!
Great to hear, Claudia! And I hear you: you absolutely can omit the sugar from the blueberries. Go for it 🙂
This recipe is insanely easy to make and a hit with a crowd every time. Perfect when Florida blueberries are in season or NJ berries have made their way to the FL supermarket shelves. Thank you Ali for all the great tips in your recipes and making cooking fun.
Great to hear this, Marianne 🙂 🙂 🙂 Thanks for writing.
