Prep Time5 minutes
Cook Time15 minutes
Total Time20 minutes
Servings: 4 servings

Ingredients

  • 1/2 pound spaghetti usually half a box
  • 2 tablespoons olive oil
  • 2 cloves garlic finely chopped
  • 1/4 teaspoon crushed red pepper flakes
  • 1 large lemon zested and juiced (approx. 1 tablespoon zest and 2 teaspoons juice)
  • 1/3 cup heavy cream
  • 1 cup grated Parmesan cheese divided
  • 1/4 teaspoon kosher salt + more to taste
  • 1/8 teaspoon freshly ground black pepper + more to taste
  • small handful parsley chopped

Instructions

  • Bring a large pot of salted water to a rolling boil and cook the spaghetti until al dente according to package directions; reserve 1 cup of the pasta cooking water, then drain the pasta.
  • While the pasta cooks, heat a large deep skillet over low heat. Add the olive oil, chopped garlic, and crushed red pepper flakes and cook, stirring, for about 1 minute until fragrant but not browned.
  • Add 3/4 cup of the reserved pasta water, the lemon juice, and the heavy cream to the skillet. Increase heat to medium and bring to a gentle boil, stirring frequently, until the sauce thickens slightly, about 2–3 minutes.
  • Stir in the lemon zest and half of the grated Parmesan, then season the sauce with kosher salt and freshly ground black pepper to taste.
  • Add the drained spaghetti to the skillet, remove from the heat, and toss with tongs for 1–2 minutes so the pasta absorbs the sauce; add a splash of reserved pasta water if needed to loosen the sauce.
  • Transfer to serving bowls and top with the remaining Parmesan and chopped parsley, then serve immediately.

Equipment

  • Large Pot
  • Large, deep skillet
  • Tongs
  • Citrus zester or microplane
  • Measuring Cups and Spoons

Notes

  • Reserve pasta water to adjust sauce consistency.
  • Do not brown the garlic to avoid bitterness.
  • Use fresh Parmesan for best flavor.
  • Adjust red pepper flakes to taste for spice level.
