Step‑by‑Step Instructions for Spaghetti Squash Carbonara
Step 1: Preheat the oven
Begin by preheating your oven to 400°F (204°C). This step is crucial for perfectly roasting the spaghetti squash. Once the oven is ready, grab your trusty baking sheet to prepare for the squash.
Step 2: Prepare the squash
Carefully slice your spaghetti squash in half lengthwise and scoop out the seeds using a spoon. Place the squash halves, flesh side down, on the lined baking sheet. Bake for 30 to 45 minutes, until the squash is fork-tender and easily shredded into strands.
Step 3: Whisk the sauce ingredients
While the spaghetti squash bakes, crack the egg yolks and eggs into a bowl. Whisk them together with finely grated parmesan until the mixture is smooth and well-combined. Set this creamy sauce aside, as it will be the star of your Spaghetti Squash Carbonara.
Step 4: Cook the bacon
In a large skillet over medium heat, add diced bacon and cook for 5 to 7 minutes until crispy. Keep an eye on the color; it should be a rich golden brown. Once crispy, add minced garlic to the skillet and sauté for about 1 minute until fragrant, enhancing the smoky goodness.
Step 5: Toss the spaghetti squash
Once the spaghetti squash is roasted, remove it from the oven and let it cool slightly. Using a fork, shred the squash into noodle-like strands, then add them to the skillet with the crispy bacon and garlic. Toss everything together, ensuring each strand is well coated in the flavorful bacon fat.
Step 6: Combine with egg mixture
Remove the skillet from heat before bringing in the egg mixture. Utilizing tongs, slowly toss the spaghetti squash with the creamy sauce, working quickly to prevent the eggs from scrambling. The residual heat will help create that luscious, creamy texture that characterizes Spaghetti Squash Carbonara.
Step 7: Serve and garnish
Now it’s time to plate your delicious creation! Divide the spaghetti squash carbonara among plates, garnishing each with a sprinkle of fresh parsley and extra parmesan for added richness. The dish should have a beautiful golden hue with crispy bites of bacon nestled throughout.

How to Store and Freeze Spaghetti Squash Carbonara
Fridge: Store leftovers in an airtight container in the refrigerator for up to 3 days. Gently reheat in a skillet over low heat to preserve creaminess.
Freezer: While freezing is not recommended due to potential sauce separation, you can freeze the cooked spaghetti squash separately for up to 2 months.
Reheating: If refrigerating, add a splash of heavy cream or broth when reheating to restore moisture and prevent dryness.

Spaghetti Squash Carbonara Recipe FAQs
How do I choose the right spaghetti squash?
Absolutely! When selecting spaghetti squash, look for ones that are firm with a smooth, even skin. Avoid any that have dark spots or soft areas, as those could indicate spoilage. Aim for a squash that feels heavy for its size; this usually means it’s full of moisture and will yield better strands.
How long can I store leftovers of spaghetti squash carbonara?
Very! You can store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, I recommend doing so gently in a skillet over low heat, adding a splash of heavy cream or broth to help restore moisture and creaminess, ensuring every bite is just as delicious as the first.
Can I freeze spaghetti squash carbonara?
While it’s not ideal to freeze the entire dish, you can freeze the cooked spaghetti squash separately for up to 2 months. To do this, scoop the cooked squash strands into a freezer-safe bag, press out the air, and seal. When you’re ready to enjoy, thaw overnight in the fridge, and quickly sauté with the sauce in a pan.
What should I consider if I have dietary restrictions or allergies?
Certainly! If you’re looking for a gluten-free or low-carb option, this spaghetti squash carbonara is perfect as written. For vegetarians, simply omit the bacon and add extra mushrooms or spinach for added flavor. If you have specific allergies, always double-check the labels on your egg and cheese products.
My sauce separated when I mixed the eggs into the spaghetti squash. What did I do wrong?
Oh no! It sounds like your eggs may have cooked too quickly. To achieve a silky sauce, it’s vital to toss the spaghetti squash with the egg mixture off the heat. The residual warmth from the squash will help cook the eggs gently. If the sauce does start to separate, you can still salvage it by whisking in a little broth or cream over low heat.
How can I tell when the spaghetti squash is cooked properly?
Definitely! The spaghetti squash is done when it’s fork-tender, which usually takes about 30 to 45 minutes at 400°F (204°C). You can test it by inserting a fork into the flesh; it should slide in easily. Properly cooked squash will easily shred into noodle-like strands when you scrape it with a fork.
