This Spaghetti Squash Carbonara is a quick-and-easy way for you to sub out regular pasta. It’s perfect in this pancetta-and-egg-enriched cream sauce. Microwaving the squash is a clever trick that cuts down on time.
Cut the squash in half crosswise using a serrated knife. Scoop out and discard the seeds with a spoon. Put the squash onto a microwave-safe plate, cover tightly with plastic wrap and microwave on high until very tender and the flesh can easily be flaked with a fork, 13 to 14 minutes. Use a fork to scrape the sides of the squash into spaghetti-like strands into a bowl.
Meanwhile, mix together the Parmesan, egg yolk, ½ teaspoon salt and a generous amount of pepper in a medium bowl.
Cook the pancetta in a large skillet over medium-high heat, stirring occasionally, until crisp, about 6 minutes. Add the garlic and red pepper flakes and cook, stirring, until fragrant, about 1 minute. Stir in the heavy cream, scraping up any brown bits in the pan, and bring to a boil. Reduce the heat to medium, add the squash strands and toss until well coated.
Add the Parmesan mixture and toss to gently cook the eggs and make a creamy sauce. Stir in the parsley. Divide among 4 plates and serve with more Parmesan, if using, and a green salad on the side.
