Recipe Steps

steps 10

1 h 10 min

  • Step 1

    To prepare the spaghetti squash, preheat an oven to 425 degrees. Cut the spaghetti squash in half, and remove the seed from the center.
    Step 1
  • Step 2

    Place the halves of squash on a lined sheet pan. Sprinkle the salt and first amount of pepper over the squash. Drizzle the olive oil over the top.
    Step 2
  • Step 3

    Flip the squash halves over so the exterior is facing up. Bake the squash for about 50 minutes, or until the squash is tender and can be pulled apart with a fork.
    Step 3
  • Step 4

    Allow the squash to cool completely. Shred the inside flesh of the squash with a fork, and discard of the exterior. Set the spaghetti squash aside for later. A whole spaghetti squash yields about 4 ½ cups. For this recipe, you will only be using 2 cups of spaghetti squash.
    Step 4
  • Step 5

    In a bowl, whisk together the eggs, first amount of parmesan cheese, and second amount of pepper. Set this aside for later use.
    Step 5
  • Step 6

    Dice the bacon and pancetta, if necessary. Cook the meat in a skillet on medium-high heat for about 4 minutes, or until the pancetta becomes browned.
    Step 6
  • Step 7

    Mince and toss the garlic into the skillet. Cook for an additional 30 seconds.
    Step 7
  • Step 8

    Add 2 cups of the cooked spaghetti squash to the skillet and the water. Gently stir the ingredients together and cook for an additional 2-3 minutes to allow the squash to soak in the flavors.
    Step 8
  • Step 9

    Remove the skillet from the heat. Pour in the egg mixture, and quickly stir all the ingredients together. Serve immediately.
    Step 9
  • Step 10

    Sprinkle 1 tsp. of parmesan cheese over each serving, and add additional black pepper if desired.
    Step 10

    I don’t have spaghetti squash today, can I use zucchini??

      Ok so I cheated and used frozen spaghetti squash noodles, cuts time down to like 12 minutes. It takes the longest to cook the bacon and pancetta. Flavor was great and the dish is super easy. I was worried about the egg part, but it was fine. And I did not add the water since the noodles were frozen that gave me enough moisture.

        I liked more than I thought I would 😀. I’m not a huge fan of bacon but I didn’t mind it too much in this recipe. I tried the recipe because I had leftover spaghetti squash. I only made it for one so I had twice the egg which I thought may not be ok, but it was fine, although I had to return the mixture to the heat cause it was too much egg for the squash to cook. I also didn’t and the water and I doubled the garlic.

            Tasted very good. Wasn’t sure about the egg mixture(because I like my eggs cooked well), but that is what made it delicious.

              Wasn’t bad, wasn’t great. Tried adding a smidge of heavy cream, but it didn’t make any difference. Would try something new before making it again.

                  How well does this reheat as leftovers?

                    You could reheat in a microwave, but only in short increments, or else the egg will cook.

                    Loved it! I took the advice of adding onion. I did not have pancetta so I doubled the bacon. I tasted it before adding the egg and it was delicious but with and without the egg. Added to favorites!

                      Wondering if lean grass fed hamburger would be good instead of bacon?

                        Yes, but then it's not carbonara anymore 😀 Now you would have a spaghetti squash beef skillet

                        Ps all beef eats grass that's added on it so companies can charge more

                        You could sub in the hamburger! However please note this will reduce your fat macros if you remove the bacon.

                        Tasted better than expected. I doubled the bacon amount and already had the spaghetti squash cooked from the previous day.
