Spaghetti aglio e olio is a classic Italian pasta dish that is simple yet incredibly flavorful. With just a few basic ingredients, you can create a delicious meal that highlights the natural flavors of garlic, olive oil, and red pepper flakes. This dish is perfect for a quick weeknight dinner or a comforting meal any time.
While most of the ingredients for spaghetti aglio e olio are common pantry staples, you might need to pick up fresh parsley if you don't have it on hand. Fresh parsley adds a bright, herbaceous note to the dish that dried parsley can't quite replicate. Make sure to also use high-quality extra virgin olive oil for the best flavor.

Ingredients For Spaghetti Aglio E Olio
Spaghetti: The base of the dish, providing a neutral canvas for the flavorful sauce.
Garlic: Thinly sliced to release its aromatic oils and infuse the dish with a rich, savory flavor.
Extra virgin olive oil: The primary fat used in the sauce, offering a fruity and robust taste.
Red pepper flakes: Adds a touch of heat to balance the richness of the oil and garlic.
Salt: Enhances the overall flavor of the dish, used both in the pasta water and for seasoning.
Parsley: Freshly chopped to add a burst of color and a fresh, herbaceous note to the final dish.
Technique Tip for This Recipe
To achieve perfectly golden garlic without burning it, make sure to slice it thinly and cook it over medium heat. If the olive oil gets too hot, the garlic can quickly turn from golden to burnt, imparting a bitter taste to your spaghetti aglio e olio. Keep a close eye on the garlic and be ready to lower the heat if necessary.
