A quick and creamy pasta dish made entirely in one pan. The starchy pasta water emulsifies with olive oil, lemon, and Parmesan to create a luxuriously silky sauce without any cream. Perfect for a bright, comforting weeknight dinner with minimal cleanup.

Ingredients

Scale
  • 12 ounces long pasta (spaghetti, linguine, or fettuccine)
  • 4 tablespoons olive oil
  • 8 cloves garlic, thinly sliced
  • 1/2 teaspoon red pepper flakes, or to taste
  • 4 cups low-sodium vegetable or chicken broth
  • 2 large lemons (for zest and juice)
  • 1/2 cup freshly grated Parmesan cheese, plus more for serving
  • 1/4 cup chopped fresh parsley
  • Salt and freshly ground black pepper to taste

Instructions

  1. In a large, deep skillet or Dutch oven, heat olive oil over medium heat. Add sliced garlic and red pepper flakes. Cook, stirring frequently, for 1-2 minutes until fragrant and just starting to turn golden at the edges. Do not let it brown.
  2. Carefully pour in the broth and add the pasta. Use tongs to gently bend and submerge the pasta as it softens. Bring to a lively simmer.
  3. Cook the pasta in the simmering broth for 9-11 minutes, stirring occasionally, until al dente and most of the liquid is absorbed.
  4. Reduce heat to low and remove the pan from the heat. Immediately stir in the lemon zest, lemon juice, and grated Parmesan. Stir vigorously to emulsify the sauce.
  5. Stir in the chopped parsley. Taste and season generously with salt and black pepper. Serve immediately with extra Parmesan.

Notes

Use fresh lemon juice, not bottled, for best flavor. Remove pan from heat before adding cheese to prevent graininess. For a dairy-free version, omit Parmesan or use nutritional yeast. Add protein like shrimp or chicken, or vegetables like spinach, in the final minutes of cooking.
