Description

This classic Italian Spaghetti Aglio e Olio recipe is a simple yet flavorful pasta dish featuring al dente spaghetti tossed with fragrant sautéed garlic, olive oil, cracked red pepper flakes, and a touch of fresh lemon juice and Parmesan cheese. Perfect for a quick and delicious meal, this recipe yields 8 servings and delivers a bold combination of garlicky, slightly spicy, and tangy flavors.


Ingredients

Scale

Spaghetti

  • 1 lb spaghetti
  • 1 tsp salt

Garlic Oil Sauce

  • 1 bulb garlic (about 20 cloves, peeled and sliced thin)
  • ¼ tsp freshly cracked black pepper
  • ½ tsp cracked red pepper flakes
  • ½ cup olive oil
  • ½ tsp salt

Finishing Touches

  • ½ cup grated Parmesan cheese
  • 1 Tbsp Italian parsley, chopped
  • 2 Tbsp lemon juice
  • ¼ cup reserved pasta water


Instructions

  1. Prepare Ingredients: Gather all your ingredients and set a large pot of water to boil. Add ½ teaspoon of salt to the boiling water to season it before cooking the pasta.
  2. Cook Pasta: Add the spaghetti to the boiling water and cook until al dente, about 10 minutes. Once cooked, drain the pasta, reserving ¼ cup of the pasta water for the sauce.
  3. Sauté Garlic: In a large saucepan over medium-low heat, add the olive oil along with thinly sliced garlic, freshly cracked black pepper, ½ teaspoon salt, and cracked red pepper flakes. Sauté gently until the garlic is fragrant and just beginning to turn golden, approximately 2 minutes. Be careful not to burn the garlic to keep the flavor pleasant.
  4. Toss Pasta: Transfer the drained spaghetti into the saucepan with the garlic-infused oil. Toss thoroughly so each strand is coated evenly.
  5. Add Finishing Ingredients: Add the grated Parmesan cheese, chopped Italian parsley, lemon juice, and 2 tablespoons of the reserved pasta water to the spaghetti. Toss continuously to allow the cheese to melt into the sauce and coat the pasta evenly. Add a bit more pasta water if you prefer a looser, silkier sauce texture.

Notes

  • Using a whole bulb of garlic (around 20 cloves) gives this dish its signature bold and irresistible flavor. Thinly slicing the garlic ensures it infuses well without burning.
  • For a spicier version known as ‘spaghetti aglio olio e peperoncino,’ fresh chili peppers can be added. However, cracked red pepper flakes offer a more controlled and convenient heat option.
