Spaghetti aglio e olio is a classic Italian pasta dish that is both simple and delicious. With just a few ingredients, you can create a flavorful meal that highlights the essence of Italian cooking. This dish is perfect for a quick weeknight dinner or a sophisticated meal to impress guests.
While most of the ingredients for spaghetti aglio e olio are common pantry staples, you may need to pick up a few items if you don't already have them. Olive oil is essential for this recipe, so make sure to use a good quality one. Red pepper flakes add a touch of heat, and if you don't have them on hand, they can be found in the spice aisle of your supermarket. Fresh garlic is a must for authentic flavor.

Ingredients For Spaghetti Aglio E Olio
Spaghetti: The base of the dish, providing a hearty and satisfying texture.
Garlic: Adds a robust and aromatic flavor that is essential to the dish.
Olive oil: The primary fat used to cook the garlic and coat the pasta, adding richness and depth.
Red pepper flakes: Provides a subtle heat that enhances the overall flavor profile.
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, keep a close eye on the garlic as it cooks in the olive oil; it can go from golden to burnt very quickly. If the garlic starts to brown too fast, lower the heat immediately to avoid a bitter taste.
