Ingredients

Scale

Pasta

  • 1 pound cooked spaghetti

Sauce

  • 1 stick salted Danish creamy butter (about 8 tablespoons)
  • 2 cloves garlic, grated
  • 1 teaspoon salt, more or less to taste
  • 1 teaspoon freshly ground black pepper
  • 3 tablespoons juice of a lemon
  • 1 tablespoon lemon zest
  • 3/4 cup reserved pasta water (plus extra if needed)
  • 3/4 cup freshly grated Parmesan cheese

Optional Garnish

  • Fresh parsley, chopped
  • Additional grated Parmesan cheese

Instructions

  1. Cook Pasta: Bring a large pot of salted water to a boil and cook the spaghetti according to package instructions until al dente. Drain the pasta, reserving 1 1/2 cups of the pasta water for the sauce.
  2. Melt Butter and Sauté Garlic: In the same large pot, melt the butter over medium heat. Add the grated garlic, salt, and freshly ground black pepper. Stir constantly for about 1 minute until the garlic is fragrant but not browned.
  3. Add Lemon and Pasta: Pour in the lemon juice and add the lemon zest, then immediately add the cooked spaghetti back to the pot. Stir to combine.
  4. Mix Sauce: Pour in 3/4 cup of the reserved pasta water and add the grated Parmesan cheese. Toss and stir the pasta vigorously to combine and create a creamy sauce that coats every strand. Add additional reserved pasta water as necessary to reach desired sauce consistency.
  5. Serve: Plate the pasta and garnish with fresh chopped parsley and extra Parmesan cheese if desired. Serve immediately while hot.

Notes

  • For best results, use freshly grated Parmesan cheese as it melts better and offers richer flavor.
  • Adjust lemon juice and zest to taste depending on how bright or tangy you prefer the dish.
  • You can substitute salted butter with unsalted butter and add salt accordingly.
  • Reserve enough pasta water as the starch helps emulsify the sauce and texture.
  • This recipe is best enjoyed fresh and should not be reheated repeatedly as the sauce may separate.
