Ingredients Overview

Though the ingredient list is short, each item plays a crucial role in creating balance and depth.

Pasta

Use long pasta like spaghetti, linguine, or fettuccine. Fresh pasta works wonderfully for a silky finish, but dry pasta is just as traditional and delicious.

• Whole wheat or gluten-free pasta also work, just be sure to cook al dente.

• Reserve pasta water—it’s key for emulsifying the sauce.

Garlic

Fresh, thinly sliced garlic infuses the oil with its flavor. Avoid mincing, which can burn quickly and turn bitter.

• Golden, not brown is the goal when cooking garlic in oil.

Extra Virgin Olive Oil

The soul of this dish. A good-quality, fruity olive oil gives the sauce richness and depth.

• Use about ¼ to ⅓ cup per 12 oz of pasta.

• Don’t substitute with lighter or neutral oils—this dish depends on the flavor of real olive oil.

Red Chili Flakes

Adds subtle heat and complexity. Adjust the amount based on your spice preference.

Fresh Parsley

Adds brightness and color, balancing the richness of the oil.

Salt & Pepper

Simple seasoning brings all the flavors together. Be generous with salt in the pasta water—it’s the only time you can season the pasta itself.

Step-by-Step Instructions

This dish comes together in under 20 minutes, start to finish.

1. Cook the Pasta

Bring a large pot of salted water to a boil. Cook pasta until al dente, according to package instructions. Reserve ¾ cup of pasta water before draining.

2. Sauté Garlic in Olive Oil

While the pasta cooks, heat ¼ cup olive oil in a large skillet over medium heat. Add the sliced garlic and cook gently, stirring often, until lightly golden—about 2–3 minutes.

• Be careful not to brown or burn the garlic.

• Add red chili flakes (½ tsp to 1 tsp) during the last 30 seconds of cooking.

3. Add Pasta Water to Sauce

Carefully pour ½ cup reserved pasta water into the pan with garlic oil—it will sizzle. Stir to create a loose emulsion.

4. Toss in the Pasta

Add the cooked, drained pasta directly to the skillet. Toss with tongs to coat in the garlic oil sauce. Add more pasta water as needed to loosen and help the sauce cling.

5. Finish and Serve

Remove from heat and toss in chopped fresh parsley (about ¼ cup). Season with salt and cracked black pepper. Serve immediately, topped with optional grated cheese or more chili flakes.

This dish is a perfect blank canvas. Here’s how to make it your own or adapt it for different preferences:

Tips for Best Results

• Use good-quality olive oil: It makes all the difference in flavor.

• Don’t overcook garlic: Golden edges = perfect. Brown garlic = bitter.

• Toss pasta in the sauce well: It helps the oil cling to each strand.

Variations

• With Anchovies: Melt 2 anchovy fillets into the oil before adding garlic for a savory umami kick.

• Add Olives or Capers: For a briny twist, toss in sliced Italian olives or drained capers.

• Lemon Twist: Add lemon zest or a squeeze of juice at the end for brightness.

• Protein Boost: Add grilled shrimp, seared scallops, or shredded rotisserie chicken.

Substitutions

• Garlic Powder (last resort): Use ½ tsp garlic powder mixed into the pasta water if you don’t have fresh garlic.

• No Parsley? Substitute with fresh basil or skip entirely.

• Gluten-Free: Use certified gluten-free pasta and check all seasoning sources.

FAQ

1. Can I use minced garlic instead of sliced?

You can, but sliced garlic gives better texture and is less likely to burn. Minced garlic cooks faster and can become bitter if overdone.

2. What pasta shapes work best?

Long noodles like spaghetti, linguine, or fettuccine are traditional. But you can also use bucatini, angel hair, or even short pasta in a pinch.

3. Can I make this dish ahead of time?

It’s best enjoyed fresh, but you can store leftovers for up to 2 days. Reheat gently with a splash of water or extra olive oil.

4. What makes this dish “Italian”?

This recipe is a traditional Neapolitan dish known as Spaghetti Aglio e Olio, deeply rooted in Southern Italian cuisine for its simplicity and flavor.

5. Can I add cheese?

Yes! Though not traditional, grated Parmesan or Pecorino Romano can be added before serving for extra depth and saltiness.

6. Can I add vegetables?

Absolutely. Sautéed spinach, mushrooms, cherry tomatoes, or broccoli florets pair well with the garlic oil base.

7. Is this dish spicy?

Only mildly—thanks to red chili flakes. You can easily adjust the heat by adding more or less, or omitting them entirely.
