• 4 ounces pancetta (or bacon), diced
• 2 garlic cloves, minced

Instructions

Step 1: Roast the Spaghetti Squash

1. Preheat the oven to 400°F (200°C).
2. Cut the spaghetti squash in half lengthwise and scoop out the seeds with a spoon.
3. Drizzle the inside of each half with olive oil, then season with salt and black pepper.
4. Place the squash halves cut-side down on a baking sheet lined with parchment paper.
5. Roast for 35–40 minutes, or until the flesh is tender and easily shredded with a fork.
6. Remove from the oven and let it rest for 5 minutes before using a fork to scrape out the “spaghetti” strands into a bowl.

Step 2: Cook the Pancetta (or Bacon)

1. While the squash is roasting, heat a large skillet over medium heat.
2. Add the diced pancetta (or bacon) and cook until crispy, about 5–7 minutes.
3. Stir in the minced garlic and sauté for another 30 seconds until fragrant.
4. Turn off the heat and set the skillet aside.

Step 3: Prepare the Carbonara Sauce

1. In a mixing bowl, whisk together the eggs, Parmesan cheese, black pepper, salt, and red pepper flakes (if using).
2. Slowly drizzle in a tablespoon of the warm pancetta drippings into the egg mixture while whisking. This prevents the eggs from scrambling when mixed into the squash.

Step 4: Combine Everything

1. Add the roasted spaghetti squash strands to the skillet with the pancetta and garlic. Toss well to combine.
2. Remove the skillet from heat and slowly pour in the carbonara sauce, stirring continuously to create a creamy coating. The residual heat will thicken the sauce without scrambling the eggs.
3. Garnish with fresh parsley and extra Parmesan cheese before serving.

Tips & Tricks

• Choosing the right squash: Look for a firm spaghetti squash with a smooth rind and no soft spots.
• Cooking shortcut: If you’re short on time, you can cook the spaghetti squash in the microwave. Cut in half, remove the seeds, and microwave cut-side down with a little water for 10–12 minutes.
• Extra creamy texture: Stir in a tablespoon of heavy cream to make the sauce richer.
• Protein boost: Add grilled chicken or shrimp for a heartier meal.
• Dairy-free option: Substitute Parmesan cheese with nutritional yeast for a dairy-free version.
