Creamy Keto Spaghetti Squash (With Pancetta, Mushrooms and Peas)

Keto Spaghetti Squash

Jump to Recipe

Our Creamy Keto Spaghetti Squash is made with crispy pancetta, peas and mushrooms. We simmer the peas and mushrooms in white wine and finish off the dish with heavy cream and Parmigiano-Reggiano. We also add shredded chicken to make this a more hearty and fulfilling meal. 


This keto dish is inspired by the classic Italian pasta dish with ham and peas (Pasta piselli e prosciutto). The dish uses prosciutto cotto which you can find in a well stocked grocery or specialty Italian grocery.  Since we swapped the pasta for the spaghetti squash, I felt that crispy pancetta would be a nice addition here instead. Feel free to use proscuitto cotto in this dish instead of the pancetta. If using prosciutto cotto, add the sliced ham at the end. There is no need to cook them ham before like we do with the pancetta. 


Is Spaghetti Squash Keto?

The simple answer is, yes! Per cup, spaghetti squash is only 42 calories with 10g of carbs and 2.2g of fiber. This makes each cup (155 grams) only 7.8g of net carbs. Spaghetti squash is great to add into a keto diet because it is high in pantothenic acid, a B vitamin. It is also a good source of vitamin C, manganese and niacin


Shredded chicken adds a really nice component to this dish. It makes this dish more filling, lower in carbs, and the texture of the shredded chicken works nicely with the spaghetti squash. You can use any precooked shredded chicken or shred a rotisserie chicken from the grocery store. Our favorite way is to cook the chicken in the Instant Pot (it only takes 10 minutes!). We use the leftover chicken stock to make the cream sauce. Directions for the Instant Pot shredded chicken is in the recipe below.

Spaghetti Squash

  • Preheat oven to 400°F.

  • Once cooked, remove the pancetta with a slotted spoon, keeping the grease in the pan. Set aside.

  • Add chopped mushrooms and fresh parsley. Cook until the mushroomed are browned, about 5 minutes. Season with salt and pepper.
