Spaghetti Squash Cacio e Pepe

Easy Meals

Cacio e Pepe (aka “cheese and pepper”) gets a higher nutrition makeover in this version made with spaghetti squash instead of pasta! It’s super easy to make, and the perfect lightened up comfort food.

Spaghetti squash is one of the most underrated vegetables out there in my opinion and one that I didn’t even really knew existed until a couple of years ago! If you see one at the grocery store it’s hard to believe that you can get squash “noodles” out of it!

Cacio e Pepe is one of my favorite meals to order at really nice Italian restaurants (in Chicago, I get it at Monteverde!) — it’s so simple, yet so good which is why I wanted to see how it would turn out with spaghetti squash! And I absolutely love it!

Spaghetti Squash Nutrition

This recipe is great for you if you are looking for a lower carb option to use instead of regular pasta. 1 cup of spaghetti squash has less than 50 calories and about 10 grams of carb per cup. It’s a good source of vitamin B6, C and fiber.

I don’t eat super low carb, but do like to add as much nutrition as possible into my meals, which is why I love using spaghetti squash in a variety of ways. This cacio e pepe rendition is so simple and delicious! Another way this spaghetti squash cacio e pepe recipe would be great is if you did half pasta, half spaghetti squash noodles.

I usually eat this meal paired with roasted chicken, or salmon. In this recipe I added fresh spinach which is not typically in cacio e pepe, however I added it here and you can definitely add any other veggies you have on hand.

How to Roast a Spaghetti Squash in The Oven

Cutting, let alone roasting a spaghetti squash can seem really overwhelming, but it doesn’t have to be! Learn how to cut and roast a spaghetti squash so that you can use it in this recipe and future recipes!

  1. Start by placing a kitchen towel under a cutting board so that it does not slip. Preheat the oven to 400 degrees F.
  2. Use a sharp knife to cut the spaghetti squash lengthwise all of the way through.
  3. Use a spoon to scoop out the stringy insides and seeds (you can totally save them for roasting just like you would with pumpkin seeds).
  4. Lay the two halves flesh down on a parchment lined baking sheet. You can sprinkle them with olive oil and add salt and pepper if desired.
  5. Bake for 25 minutes, and remove from the oven.
  6. Using tongs (the squashes will still be hot!) flip them over and let cool for 10-20 minutes. This helps you to be able to get the “noodles” out really easily.
  7. Use a fork to scrape down the spaghetti squash to pull out the noodles. Keep going until you get to the skin and repeat with the other half!
