A recipe for creamy Alfredo sauce served over roasted spaghetti squash, offering a low-carb alternative to traditional pasta.

Ingredients

Scale
  • 1 medium spaghetti squash
  • 4 tablespoons unsalted butter
  • 2 cloves garlic, minced
  • 1 cup heavy cream
  • 1/2 cup grated Parmesan cheese, plus more for serving
  • 1/4 teaspoon salt
  • 1/8 teaspoon black pepper
  • Pinch of nutmeg

Instructions

  1. Preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius).
  2. Cut the spaghetti squash in half lengthwise. Scoop out the seeds and stringy pulp.
  3. Place the squash halves cut-side down on a baking sheet. Roast for 30 to 40 minutes, or until the flesh is tender when pierced with a fork.
  4. Remove the squash from the oven and let it cool slightly. Use a fork to scrape out the strands of squash flesh into a bowl. Set aside.
  5. While the squash cools, prepare the sauce. Melt the butter in a medium saucepan over medium heat.
  6. Add the minced garlic and cook for about 1 minute until fragrant. Do not let the garlic brown.
  7. Pour in the heavy cream and bring the mixture to a gentle simmer, stirring occasionally. Reduce the heat to low.
  8. Stir in the Parmesan cheese until the sauce is smooth and thickened.
  9. Season the sauce with salt, pepper, and nutmeg. Taste and adjust seasoning as needed.
  10. Add the spaghetti squash strands to the sauce and toss gently to coat everything evenly.
  11. Serve immediately, topped with extra Parmesan cheese.

Notes

  • To prevent watery squash, roast the squash until just tender. After scraping the strands, you can gently press them between paper towels to remove excess moisture before adding the sauce.
  • For a lighter sauce, substitute half-and-half for heavy cream, but the sauce will be less thick.
  • Add cooked, shredded chicken or sautéed shrimp for a complete protein meal.
