    Spaghetti Squash Carbonara scratches the itch for pasta while remaining deliciously low carb. Spaghetti squash noodles are tossed in a rich and creamy sauce and then topped with crispy bacon and parmesan cheese for a meal that never fails to hit the spot.

    If you love pasta as much as I do, spaghetti squash is going to be your new BFF!

    You would never know looking at a spaghetti squash that the flesh would easily shred into noodle-like strands when you cook it.  

    It is one of my favorite low-carb and gluten-free pasta alternatives.

    It has a mild, delicate flavor that readily absorbs the flavors it is cooked with, making it perfect for recipes like this Spaghetti Squash Carbonara.

    Next time you are craving your favorite pasta dish, give this easy-to-make recipe a try.

    Ingredients for Making Keto Spaghetti Squash Carbonara

    • Spaghetti Squash: Pick a squash that is hard and feels heavy for its size. If you keep it in a dark place, it should stay fresh for about a month.
    • Bacon:  You can use your preferred type of bacon, but read the label to ensure that it does not have added sugar.
    • Cream:  I recommend using heavy cream, but if you are not keto you could substitute half and half.
    • Eggs:  Large eggs work best here. I used whole eggs, but if you would like to just use the egg yolk, eight egg yolks can be substituted. 
    • Parmesan:  Use freshly grated parmesan for the fullest flavor
    • Seasonings:  Adjust the amount of seasonings to your liking.

    Serving Suggestions

    Because spaghetti squash is already higher than many dishes in carbohydrates, I recommend serving this with a simple green salad with a zero-carb dressing. Or, you can use it as a side dish to keto grilled chicken.

    Storage

    You can store this low-carb spaghetti squash carbonara in the refrigerator for up to three days. I recommend reheating it in a skillet or in the oven.

    You can freeze leftovers, but the cream sauce will separate a bit. Additionally, you can expect the squash to have a softer texture.

    How to Make Spaghetti Squash Carbonara

    First, start by preheating your oven and linking a baking sheet with parchment paper.

    Using a very sharp knife, slice the spaghetti squash lengthwise. (Be careful!)

    In a large skillet, cook the bacon until it is crispy.

    Remove the bacon from the skillet, and add the squash noodles and heavy cream.

    Tilt the pan sideways, and remove about two tablespoons of the cream from the skillet.

    Enjoy all the flavors of pasta carbonara in a delicious low carb dish!
