Ingredients for Spaghetti Aglio e Olio
Spaghetti: The main pasta component, typically made from durum wheat and water.
Garlic: Thinly sliced to release its full flavor when sautéed.
Olive oil: Used as the base for the sauce, providing richness and depth.
Red pepper flakes: Adds a touch of heat to the dish.
Salt: Enhances the overall flavor of the pasta.
Parsley: Optional, but adds a fresh, herbaceous note when chopped and sprinkled on top.
Parmesan cheese: Optional, but offers a savory, umami flavor when grated over the finished dish.
Technique Tip for This Recipe
When preparing garlic for spaghetti aglio e olio, slice it thinly and evenly to ensure it cooks uniformly. This prevents some pieces from burning while others remain undercooked. Additionally, monitor the heat closely when sautéing the garlic in olive oil; it should turn golden but not brown, as burnt garlic can impart a bitter taste to the dish.
