Authentic spaghetti aglio e olio: sliced garlic bloomed slowly in olive oil with chili, emulsified with pasta water into a glossy sauce.

Prep

Serves
4 servings

Ingredients

  • 1 lb (450 g) spaghetti
  • 6 cloves garlic, sliced paper thin
  • ½ cup (120 ml) good extra virgin olive oil
  • 1 tsp red chili flakes
  • Large handful flat-leaf parsley, chopped
  • Salt for the water — it should taste like the sea

Instructions

  1. 01

    Start the water. Boil heavily salted water and drop the spaghetti. Pull it two minutes shy of the box.

  2. 02

    Bloom the garlic. Cold oil, sliced garlic, low heat. Take it to pale gold over five minutes — brown garlic is bitter and there is no fixing it.

  3. 03

    Add chili. Chili flakes in for the last 30 seconds, off the direct heat.

  4. 04

    Emulsify. Pasta into the pan with a full cup of starchy water. Toss hard over medium heat until the oil and water turn creamy and cling.

  5. 05

    Finish. Parsley off the heat, one more turn, straight into warm bowls.

Larry’s rule: The sauce is an emulsion, not a pour. If it looks oily in the bowl, you did not toss it hard enough with the pasta water.

Before you cook

What to know about Spaghetti Aglio e Olio

What it is

Spaghetti Aglio e Olio is a pasta recipe rooted in Campania's tomato-rich, ingredient-first cooking. This version makes 4 servings in 17 min and focuses on the technique that gives the dish its characteristic texture and flavor.

Why this method works

The method builds flavor in a deliberate order: start the water, then bloom the garlic, then add chili. Following that sequence keeps the main ingredients distinct while bringing the finished dish together.

Key ingredients and what they do

  • 1 lb (450 g) spaghetti — provides the recipe's main structure, so its cooking time and texture matter.
  • 6 cloves garlic, sliced paper thin — provides the aromatic character; use it at the stage specified so it stays distinct.
  • ½ cup (120 ml) good extra virgin olive oil — builds the savory foundation and carries flavor through the dish.
  • 1 tsp red chili flakes — provides the aromatic character; use it at the stage specified so it stays distinct.

Smart substitutions

For the most reliable result, keep the main ingredient and technique unchanged. Swap only like for like, then adjust salt, moisture and cooking time to taste.

Make ahead and leftovers

Prepare the measured ingredients ahead, but cook and sauce the pasta close to serving. Refrigerate leftovers promptly and reheat gently with a splash of water.

What to serve with it

  • Serve as a first course before a simple roast or vegetable dish.
  • Pair with a crisp salad or bitter greens to balance the pasta.

Larry’s why

Why Larry finishes the pasta in the sauce

Draining pasta and ladling sauce on top leaves two separate things on a plate. Pull the pasta a minute shy of al dente, move it into the sauce pan with a splash of the cooking water, and toss over heat. The starch in that water emulsifies the fat and glues the sauce to every strand.

Larry’s rule: Undercook by a minute, finish in the pan.

Quick answer

How do you cook sausage and peppers in the oven?

Roast sausage and peppers at 400°F (205°C) for 35 to 40 minutes on a single sheet pan. Toss the peppers and onions with olive oil and salt, nestle whole sausages on top, turn everything once at 20 minutes, and finish when the sausage reads 160°F.
