Ingredients
- 12 oz spaghetti
- 3 tbsp olive oil
- 4 cloves, minced garlic
- 1/4 tsp red pepper flakes
- 1/2 cup heavy cream
- 1/2 cup, freshly grated Parmesan cheese
- 1/4 cup, reserved pasta water
- to taste salt
- 1/4 tsp black pepper
Instructions
- Step 1: Bring a large pot of salted water to a rolling boil. Add 12 oz spaghetti and cook for 8-10 minutes until al dente, then drain and immediately reserve 1/4 cup pasta water.
- Step 2: While pasta cooks, heat 3 tbsp olive oil in a large skillet over medium heat. Add 4 minced garlic cloves and 1/4 tsp red pepper flakes, sautéing for 30 seconds until fragrant and golden—do not brown the garlic.
- Step 3: Add the drained spaghetti to the skillet along with 1/4 cup reserved pasta water and 1/2 cup heavy cream, stirring until the sauce begins to thicken and coat the pasta.
- Step 4: Stir in 1/2 cup grated Parmesan cheese until melted and smooth, adding more reserved pasta water if needed to reach a creamy consistency. Season with salt and 1/4 tsp black pepper to taste, then toss for 1 minute until the cheese fully melts.
