In this simple recipe, baked spaghetti squash, pulled with a fork to create noodles, replaces pasta in the classic dish cacio e pepe. Dressed with olive oil, cheese, salt, and pepper, the sweet spaghetti squash takes so well to salty and sharp Pecorino.

I’ve had this recipe for cacio e pepe spaghetti squash bookmarked since last fall, when I first found myself flipping through Skinny Taste’s latest cookbook: One and Done.

The only thing keeping me from making it has been the spaghetti squash itself, which is something I would cook more often if I didn’t find it terrifying to open.

But a few weeks ago, upon stumbling upon an America’s Test Kitchen video offering winter squash-opening guidance, I felt inspired to give it a go. Though my attempt at the ATK method — using a rubber mallet to gently tap the knife through the squash — was not as smoothly executed as I had hoped, it got the job done, and before long the squash was roasting away.

This is a very simple preparation, inspired by the classic dish cacio e pepe, which calls for tossing noodles with nothing more than olive oil, pasta cooking liquid, cheese, salt, and pepper. As it turns out, the minimalist seasonings — the saltiness and sharpness of the Pecorino in particular — are a perfect match for the warm, sweet squash.

The Right Way to Cut Spaghetti Squash

  • Thanks to Commenters for This Tip: Cut the squash crosswise as opposed to lengthwise. Counterintuitively, cutting spaghetti squash crosswise produces longer, more spaghetti-like strands. Interesting, right? Bonus: it’s easier, too.

3 Easy Ways to Cut Spaghetti Squash

  1. Knife/mallet method: Wet a cloth napkin or towel and lay it beneath a cutting board — this will secure it. Place the squash on the board. Using a sharp chef’s knife, cut into the spaghetti squash’s flesh but stop once the blade is secured in the squash. Use a rubber mallet to gently tap straight down on the top of the knife’s handle. As you tap, the knife should move through the flesh, and the spaghetti squash should split open.
  2. Microwave method: Using a sharp paring knife, make cuts all around and into the flesh of the spaghetti squash. Microwave on high for 1 minute. Remove. Let cool briefly. Using a sharp chef’s knife cut the squash in half. If the skin is still too tough, return to the microwave for another minute minutes. (Note: You can cook the spaghetti squash entirely in the microwave, but know that you’ll have to remove the seeds after you cook it, and the flavor will be more steamed as opposed to roasted.)
  3. Instant Pot Method: No need to poke any holes in it. Place 1 cup of water into the Instant Pot, set the squash on a trivet, and cooked it at high pressure for 5 minutes, then do quick release. Remove spaghetti squash. Let cool briefly. Using a sharp chef’s knife cut the squash in half. If the skin is still too tough, return to the Instant Pot for another five minutes. (Note: You can cook the spaghetti squash entirely in the Instant Pot (30 minutes, high pressure) but know that you’ll have to remove the seeds after you cook it, and the flavor will be more steamed as opposed to roasted.)

How to Bake Spaghetti Squash, Step by Step

First, halve your spaghetti squash: see notes above for various methods on how to do so.

crosswise. It’s counterintuitive, but you’ll get longer strands if you cut it crosswise.

Description

This spaghetti squash recipe is from Skinny Taste’s One and Done Cookbook. It can be served as a side dish, but to make it a meal, I like to pair it with chickpeas simmered in their cooking liquid with lots of sautéed onions and garlic.

*Update Thanks to Commenters!*: Cut the squash crosswise as opposed to lengthwise. Cutting crosswise is not only easier but also (counterintuitively) produces longer, more spaghetti-like strands. Interesting, right? See the newly added video for cutting guidance.

If you have a microwave: Use it to soften the flesh of the spaghetti squash, thereby making it easier to cut into. One minute on high should do it, but continue to cook at 1 minute intervals if skin is still too hard after the first pass.

You can also you an Instant Pot. No need to poke any holes in it. I use 1 cup of water and cook the squash at high pressure for 5 minutes, then do a quick release. This softens the skin enough to make cutting easier.

UPDATE 10/17/2021: I now roast my squash at 350ºF for 45 minutes (as opposed to at 400ºF for 55-60 minutes). This shorter cook period yields firmer strands, which I like. A delicious way to serve this squash is tossed with this baked feta and cherry tomatoes. 

Ingredients

for the squash:

  • 1 medium spaghetti squash, (2 3/4 to 3 pounds)
  • kosher salt, for seasoning
  • fresh cracked black pepper, to taste
  • 1 to 2 tablespoons extra virgin olive oil
  • 1/2 cup finely grated Pecorino Romano cheese

for the chickpeas:

  • 3 tablespoons olive oil
  • 1 to 2 onions thinly sliced to yield 1-2 cups
  • 4 cloves garlic, thinly sliced or minced
  • pinch crushed red pepper flakes
  • 2 cups cooked chickpeas in their cooking liquid
  • flaky sea salt for finishing

Instructions

  1. Heat oven to 350ºF. Line a sheet pan with foil or parchment paper.
  2. Halve the spaghetti squash crosswise and use a spoon to scrape out the seeds and stringy yellow strands, then discard. (See notes in post and above for how to cut open a spaghetti squash.)
  3. Season the flesh with a pinch of salt & pepper then place the squash cut side down on the prepared pan.
  4. Bake until the flesh can be easily pierced with a fork, 55 to 60 minutes. Remove the pan from the oven and let cool for 10 minutes. UPDATE: I now roast my squash at 350ºF for 45 minutes. The squash will not be knife tender. This shorter cook period yields firmer strands, which I like. If you have made this recipe in the past and have liked it, keep doing what you like, but otherwise, try cooking it for 45 minutes. Note: With this shorter cooking period, the squash will not be knife or fork tender when you remove it from the oven. 
  5. Using a fork, gently pull the squash flesh from the sides and scrape into a bowl; it will separate into spaghetti-like strands.
  6. Add olive oil, Pecorino Romano, and 1/2 teaspoon black pepper. Toss well and serve immediately, or to make the chickpeas, continue on.
  7. To make the chickpeas: Heat the oil in a large pan over medium heat. Add the onions and a pinch of salt, and cook, stirring every so often, till they begin to caramelize, 7 to 1o minutes. Add the garlic and pepper flakes to taste, and cook for a minute more. Add the chickpeas and 2 cups of cooking liquid and bring to a simmer. Simmer gently for 10 minutes or until chickpeas begin breaking down. Taste. Add salt and pepper to taste. Add liquid as needed to keep the chickpeas somewhat brothy.
  8. To serve. Spoon chickpeas into a bowl. Top with a spoonful of spaghetti squash. Use a microplane to shave more Pecorino over top. Serve, passing more salt and pepper on the side.
