Step‑by‑Step Instructions for Spaghetti Squash Carbonara
Step 1: Preheat the Oven
Preheat your oven to 400°F (200°C) and prepare a baking sheet by lining it with parchment paper. This will keep the spaghetti squash from sticking while it roasts, ensuring that you achieve perfectly tender strands.
Step 2: Prepare the Spaghetti Squash
Halve the spaghetti squash lengthwise and scoop out the seeds using a spoon. Place the squash cut-side down on the prepared baking sheet. Bake in your preheated oven for 30 minutes, or until the skin is tender and the strands are easily forked.
Step 3: Cook the Bacon
While the squash is baking, chop your bacon into small pieces and heat a skillet over medium heat. Add the bacon to the skillet, cooking it until crispy—about 6-8 minutes. Once done, transfer the bacon to a plate and leave the grease in the skillet for added flavor in your Spaghetti Squash Carbonara.
Step 4: Cook the Chicken Thighs
Season the boneless skinless chicken thighs with Italian seasoning, sea salt, and black pepper. In the same skillet with the bacon grease, add the chicken and cook for approximately 12 minutes, turning halfway through, until golden brown and cooked through. Remove the chicken from the skillet and slice it thinly.
Step 5: Whisk the Sauce Ingredients
In a separate bowl, combine almond milk, chicken broth, arrowroot starch, sea salt, and garlic powder. Whisk everything together until smooth, ensuring there are no lumps in the mixture. This creamy sauce will bring richness to your Spaghetti Squash Carbonara.
Step 6: Combine Squash and Sauce
Once the spaghetti squash has cooled slightly, scoop the flesh out with a fork, separating it into strands while discarding the shells. Add the spaghetti squash strands to the skillet, allowing them to soak up the flavors as the base for your carbonara.
Step 7: Simmer the Sauce
Pour the sauce mixture into the skillet with the spaghetti squash. Simmer on medium heat for about 4 minutes, stirring frequently to ensure it thickens properly. The sauce should cling to the squash strands, creating a perfect creamy coating.
Step 8: Finish with Greens and Meats
Stir in the fresh spinach, allowing it to wilt into the warm mixture. Then, add the cooked bacon and sliced chicken back into the skillet, mixing everything together to combine the flavors thoroughly in your Spaghetti Squash Carbonara.
Step 9: Serve and Garnish
Scoop the creamy spaghetti squash carbonara onto plates while hot. If desired, garnish with freshly grated Pecorino Romano or Parmesan cheese and sprinkle with chopped fresh parsley for a fresh touch. Enjoy this delightful dish warm!

Expert Tips for Spaghetti Squash Carbonara

Spaghetti Squash Carbonara Recipe FAQs
What is the best way to select spaghetti squash?
Absolutely! When choosing spaghetti squash, look for a firm, tan-colored squash with minimal blemishes. Avoid any that have dark spots or feel soft; these may be overripe. A good squash should feel heavy for its size, indicating it’s filled with watery goodness that will yield those tender strands.
How long can I store leftovers of spaghetti squash carbonara?
You can store leftovers of spaghetti squash carbonara in an airtight container in the fridge for up to 3 days. Be sure to let it cool before storing to maintain its creaminess. When you’re ready to enjoy it again, gently reheat on the stovetop over low heat or in the microwave for a quick meal.
Can I freeze spaghetti squash carbonara?
Yes, you can! For longer storage, freeze spaghetti squash carbonara in airtight containers for up to 2 months. Ensure the dish has cooled completely before packaging. When you’re ready to eat, thaw it overnight in the refrigerator, and reheat gently on the stovetop. Adding a splash of almond milk or broth will help restore its creamy consistency!
What should I do if my sauce is too thin?
If your sauce ends up too thin, no worries! You can thicken it by creating a slurry using equal parts arrowroot starch and water. Mix the starch with a little cold water until smooth, then stir it into your sauce while simmering. Let it cook for a couple of minutes until it thickens up nicely. Another trick is to let the sauce simmer longer without a lid to reduce and intensify the flavors.
Are there any dietary considerations for this recipe?
Very! This spaghetti squash carbonara is suitable for those following a Paleo or Whole30 diet, being entirely dairy-free and low-carb. If you’re serving it to someone with nut allergies, substitute almond milk with coconut milk, but ensure it’s not sweetened. Also, if you’re looking for more plant-based options, turkey bacon or a veggie bacon alternative can be used for those avoiding meat.
