How to Make Aglio e Olio
Aglio e olio is pasta at its most essential — just garlic, olive oil, and spaghetti. Cook the pasta until almost done, then finish it in a pan where you've gently cooked sliced garlic in good olive oil until fragrant. The starchy pasta water creates a silky sauce that coats every strand.

Ingredients
- 1 pound spaghetti
- 4-6 garlic cloves
- 1/3 cup olive oil
- 1/4 teaspoon red pepper flakes
- 1/4 cup pasta water
- to taste salt
- optional fresh parsley
Step by step
- Start the pasta water. Bring a large pot of salted water to a rolling boil. Use enough salt that the water tastes like mild seawater. Drop in 1 pound of spaghetti when the water is ready.
- Prep the garlic. While the water heats, slice 4-6 garlic cloves as thin as you can manage. Paper-thin slices cook evenly and won't burn. Remove any green germ from the center of the cloves.
- Heat the oil. Pour 1/3 cup good olive oil into a large skillet or sauté pan. Set it over medium-low heat. The oil should warm gently — no bubbling yet.
- Cook the garlic. Add the sliced garlic to the warm oil. It should sizzle very gently. Stir occasionally and watch carefully — the garlic is ready when it turns pale golden and smells nutty, about 2-3 minutes. Never let it brown.
- Add heat if using. If you want spice, add 1/4 teaspoon red pepper flakes to the oil with the garlic. Let them bloom in the warm oil for 30 seconds.
- Reserve pasta water. Before draining the pasta, scoop out 1 cup of the starchy cooking water with a ladle or measuring cup. This is your sauce base.
- Combine pasta and oil. Drain the pasta when it's still slightly firm — about 1 minute shy of package directions. Add it directly to the pan with the garlic oil. Toss everything together over medium heat.
- Create the sauce. Add 1/4 cup of pasta water and toss vigorously. The water should emulsify with the oil, creating a light, silky coating. Add more water gradually if needed. Toss for 1-2 minutes until the pasta finishes cooking in the sauce.
- Finish and serve. Remove from heat. Add chopped fresh parsley if you have it, and a final drizzle of your best olive oil. Taste for salt. Serve immediately in warmed bowls.
Tips & troubleshooting
- Use the best olive oil you have — it's half the dish
- Keep the heat low when cooking garlic to prevent burning
- Save extra pasta water — you can always add more but can't take it back
- Warm your serving bowls with hot water before plating
- Never add cheese unless you're making a variation — this dish is perfect as is
Variations
- With anchovies. Add 3-4 oil-packed anchovy fillets to the oil with the garlic. They'll melt into the oil and add depth without fishiness.
- With lemon. Finish with the zest and juice of half a lemon. Add the zest with the parsley, the juice just before serving.
- With breadcrumbs. Toast panko breadcrumbs in a dry pan until golden. Sprinkle over the finished pasta for texture.
- With greens. Add a handful of baby spinach or arugula to the pan just before tossing with pasta. They'll wilt into the sauce.
Questions
- What type of pasta works best?
- Spaghetti is traditional, but any long pasta like linguine or angel hair works well. The thin strands hold the oil better than short shapes.
- Can I make this ahead of time?
- No. Aglio e olio must be served immediately. The sauce will separate and the pasta will absorb all the oil if it sits.
- How much garlic should I really use?
- Start with 4 cloves for 1 pound of pasta. You can always use more next time, but burnt garlic ruins the dish.
- What if I don't have good olive oil?
- This dish relies on olive oil for flavor, so use the best you can find. Regular olive oil will work, but extra virgin makes a noticeable difference.
- Why is my sauce not coming together?
- The pasta water needs to be starchy enough to emulsify. Make sure you're using the cooking water, not fresh water, and toss vigorously while adding it gradually.
