Spaghetti Aglio e Olio (Garlic and Olive Oil Pasta)

Aglio e olio is the kind of recipe that reveals how much flavor lives in the simplest ingredients when handled with a little attention. In this version, thinly sliced garlic is slowly warmed in a generous measure of extra-virgin olive oil until just golden, releasing a sweet, nutty aroma rather than the bitter note you get when garlic fries too fast. The trick is the pasta water: its starch tames the oil into a glossy emulsion that clings to each strand of spaghetti, carrying heat, salt and chile evenly so every bite is both silk and bite.

This dish is perfect for weeknights, last-minute dinner guests, or when your pantry is better stocked than your fridge. It responds well to small interventions — a squeeze of lemon, a scattering of toasted breadcrumbs, or a few anchovy fillets whisked into the oil — so it’s both reliable and adaptable. The recipe here favors clarity of technique over gimmicks: control the heat, reserve enough pasta water, and finish off with parsley and fresh-grated cheese only if you want that creamy umami lift.

Instructions

Cook the pasta

Bring a large pot of water to a rolling boil, add the kosher salt, then add the spaghetti and cook until just al dente according to package directions. Before draining, reserve about 1 cup (240 ml) of the pasta cooking water, then drain the pasta.

For this step

  • 12 ozSpaghetti
  • 1 tbspKosher salt (for pasta water)
Cook the pasta

Infuse the oil

While the pasta cooks, warm the olive oil in a large skillet over low–medium heat. Add the thinly sliced garlic and cook gently, stirring, until the garlic is soft and just turning golden (do not let it brown). Stir in the red pepper flakes for the last 30 seconds to bloom the spice.

For this step

  • 0.38 cupExtra-virgin olive oil
  • 6 cloveGarlic, thinly sliced
  • 1 tspRed pepper flakes
Infuse the oil

Combine pasta and oil

Add the drained spaghetti to the skillet (or return pasta to the pot and pour the garlic oil over it). Toss to coat, then add a few tablespoons of the reserved pasta water and continue tossing, adding more water as needed to create a silky emulsion that clings to the pasta. Taste and adjust salt as needed.
Combine pasta and oil

Finish and season

Remove from heat and stir in the chopped parsley and freshly ground black pepper. If using, add the grated Parmesan or Pecorino and toss until combined, adding a splash of pasta water if needed to loosen the sauce.

For this step

  • 0.25 cupFresh parsley, chopped
  • 0.5 cupFreshly grated Parmesan or Pecorino (optional)
  • 0.25 tspFreshly ground black pepper
Finish and season

Serve

Divide among warmed bowls and serve immediately. Offer extra grated cheese and red pepper flakes at the table.

Tips from the kitchen

Slice garlic uniformly

Cut garlic into even thin slices so they cook at the same rate and you avoid a mix of raw and burnt pieces.

Low and slow oil

Warm the oil over low–medium heat and be patient; gentle heat extracts sweetness without browning, which keeps the sauce clean-tasting.

Reserve enough water

Save at least 1 cup of pasta water — its starch is essential to create a silky emulsion and loosen the sauce if it tightens too much.

Bloom the chile

Add red pepper flakes at the end of the garlic step for 20–30 seconds to bloom the spice without burning or turning it bitter.

Use residual heat

Finish tossing the pasta off the heat to avoid overcooking the garlic and to let the emulsion form without evaporating the liquid.

Variations & substitutions

Anchovy and caper

Mince 2–3 anchovy fillets into the oil at the start to melt them in and add 1 tablespoon of capers at the end for briny depth.

Lemon and herb

Brighten the dish with 1 teaspoon finely grated lemon zest and a splash of lemon juice before serving, and swap half the parsley for basil for a fresher note.

Toasted breadcrumb crunch

Toast 1/2 cup of panko in a tablespoon of olive oil until golden and sprinkle over the finished pasta for texture and a nutty flavor.

Vegan/cheese-free

Skip the cheese and add an extra tablespoon of finely chopped parsley plus a squeeze of lemon to compensate for the missing umami and brightness.

Storage & make-ahead

Store leftovers in an airtight container in the refrigerator for up to 2 days; the pasta will firm and absorb oil as it cools. To reheat, warm a skillet with a splash of olive oil or reserved pasta water and toss the pasta over medium heat until loosened and glossy, rather than microwaving straight from cold which can make it dry and clumpy. If you plan to meal-prep, keep the garlic oil separate and toss just before serving.

What to serve with it

Serve aglio e olio simply with a crisp green salad (arugula with lemon vinaigrette works well) and crusty bread to mop up any remaining oil. For wine, choose a bright, unoaked white like Vermentino or Pinot Grigio, or a chilled light red such as a young Chianti if you prefer red; the acidity will cut through the oil and balance the garlic. Plate by twirling nests of spaghetti into warmed shallow bowls, finishing with a scatter of parsley, cracked black pepper, and optional grated cheese.

Frequently asked questions

What temperature should I cook the garlic at?

Cook it over low–medium heat so the garlic softens and turns just golden; too high a heat will brown it quickly and introduce bitterness.

Can I use minced garlic instead of sliced?

You can, but minced garlic cooks faster and is more likely to brown; if using minced, lower the heat and watch it closely, or add it a bit later in the process.

How much red pepper should I use?

The recipe’s 1 teaspoon is a balanced starting point for four servings; reduce for less heat, or increase and toast briefly in the oil if you want a spicier punch.

Do I have to use Parmesan or Pecorino?

No — cheese is optional here. If you skip it, boost acidity with lemon or add a pinch of saltier elements like a few chopped anchovies or capers to replace the umami.

Will this work with other pasta shapes?

Yes — long strands like linguine or bucatini hold the oil particularly well, but small shapes like orecchiette also work because the starchy water helps coat them.

Why did my sauce separate or seem oily?

That usually means not enough pasta water or too much heat. Return the pasta to the pan off the heat and whisk in a tablespoon or two of reserved pasta water at a time until the sauce emulsifies into a glossy coating.
