Parmesan Cheese – 4 oz, finely grated for that savory flavor that makes carbonara so decadent.

For the Protein
Bacon – about 12 ounces adds a rich, smoky essence; consider pancetta or guanciale as tasty substitutes.

For the Aromatics

Step‑by‑Step Instructions for Spaghetti Squash Carbonara

Step 1: Preheat the Oven
Start by preheating your oven to 400°F (200°C). This temperature is perfect for roasting the spaghetti squash to achieve tender, noodle-like strands. While the oven heats up, prepare the squash by slicing it in half lengthwise and scooping out the seeds.

Step 2: Roast the Squash
Place the halved spaghetti squash, flesh side down, on a parchment-lined baking sheet. Roast in the preheated oven for 30-45 minutes, or until the squash feels tender when pierced with a fork. You’ll know it’s ready when the skin turns a golden hue and the flesh can easily be scraped into strands.

Step 3: Prepare the Sauce
While your spaghetti squash roasts, whisk together 2 yolks, 2 whole eggs, and the finely grated parmesan cheese in a mixing bowl. Make sure the eggs are at room temperature for better emulsification. Whisk until the mixture is smooth and creamy, setting it aside to allow flavors to meld while the squash cooks.

Step 4: Cook the Bacon
In a large skillet over medium heat, add the chopped bacon and cook for about 5-7 minutes, or until crispy and golden brown. The sizzling sound and aroma of smoky bacon will fill your kitchen! Once crispy, add 3 minced garlic cloves and sauté for an additional minute until fragrant, stirring frequently to prevent burning.

Step 5: Combine Ingredients
After removing the spaghetti squash from the oven, let it cool slightly. Then, use a fork to scrape the flesh into strands and transfer them to the skillet with the bacon and garlic. Toss everything together gently, ensuring the squash is coated with the delicious bacon fat for added flavor before removing the skillet from the heat.

Step 6: Add the Sauce
Immediately pour the egg and cheese mixture over the warm spaghetti squash in the skillet. Toss quickly and thoroughly to combine, allowing the residual heat to cook the eggs gently, creating a creamy carbonara sauce. Be cautious not to scramble the eggs; you want a smooth, velvety finish. Garnish your Spaghetti Squash Carbonara with chopped parsley and extra parmesan before serving.

Expert Tips for Spaghetti Squash Carbonara

  • Room Temperature Eggs: Make sure your eggs are at room temperature for optimal emulsification in your creamy sauce. Chilled eggs can result in a lumpy texture.

  • Avoid Scrambling: Remove the skillet from heat before adding the egg mixture to prevent scrambling. This ensures you achieve that silky carbonara sauce.

  • Perfect Roasting: Roast the spaghetti squash until it’s fork-tender and the skin has a golden hue. Undercooked squash won’t provide that delightful, noodle-like texture.

  • Sauce Consistency: If reheating leftovers, add a splash of heavy cream or broth to maintain the creamy consistency of the Spaghetti Squash Carbonara.

  • Protein Variations: Experiment with swapping bacon for shrimp or chicken to cater to different palates, while staying within the low-carb theme.

Spaghetti Squash Carbonara Recipe FAQs

How do I choose a ripe spaghetti squash?

What should I do if my sauce is too thick?
If your sauce ends up too thick, don’t worry! Just add a little warm broth or heavy cream while tossing the spaghetti squash in the skillet. This will help to loosen it up and keep that silky consistency you’re aiming for. Always remember to reheat gently, as high heat can cause the sauce to break.

Are there any allergens in this recipe?
Yes, there are a few allergen considerations to keep in mind. The recipe includes eggs and cheese, which are common allergens.
