Instructions

  1. Step 1: Bring 4 quarts of water to a rolling boil in a large pot. Add 1/2 cup kosher salt and 8 oz spaghetti, stirring to prevent sticking, and cook for 8-10 minutes until al dente.
  2. Step 2: While pasta cooks, finely mince 6 garlic cloves and heat 4 tbsp extra-virgin olive oil in a large skillet over medium-low heat. Add minced garlic and 1/2 tsp red pepper flakes, sautéing gently for 2 minutes until garlic is fragrant but not browned.
  3. Step 3: Drain the cooked spaghetti, reserving 1 cup pasta water, and immediately add it to the skillet with the garlic oil. Toss vigorously for 1 minute until the sauce clings to the strands. Stir in 1/4 cup chopped parsley, 1/2 tsp kosher salt, and 1/4 tsp black pepper until the sauce thickens and coats the pasta evenly.
