Rooted in the heart of Southern Italy, this dish brings together pasta, garlic, and olive oil in perfect harmony — a recipe that has fed generations with its comforting warmth.

Why People Will Love Spaghetti Aglio e Olio:

Simplicity at its finest – just a handful of everyday ingredients transform into a dish bursting with flavor, showing the beauty of minimalism in cooking.

Comfort in every bite – warm, garlicky olive oil coating perfectly cooked pasta creates a soothing, familiar taste that feels like home.

A balance of flavors – the richness of olive oil, the bite of garlic, the heat from chili flakes, and the brightness of lemon come together in harmony.

Timeless tradition – rooted in Italian heritage, it carries with it centuries of culinary wisdom and rustic authenticity.

Endlessly versatile – it can be enjoyed as a quick weeknight dinner, an elegant meal for guests, or the perfect midnight snack.

Key Ingredient:

Garlic – the soul of the dish, sliced thin and gently simmered in olive oil to release its fragrance, it transforms into golden bites that infuse the pasta with warmth and depth.

Extra Virgin Olive Oil – not just a cooking fat, but the liquid gold that carries and elevates every flavor, creating a velvety coating on each strand of spaghetti.

Red Pepper Flakes – a subtle but fiery spark that awakens the palate, offering heat that lingers without overwhelming.

Fresh Italian Parsley – a burst of herbal brightness that balances the richness of the oil, adding color and freshness to the dish.

Parmesan Cheese & Lemon Juice – a duo of savory umami and zesty brightness, melting and binding the flavors together while keeping the pasta light yet satisfying.

Expert Tips:

Control the garlic heat carefully – cook the garlic over low to medium-low heat to slowly draw out its sweetness. If it browns too fast, it will turn bitter and dominate the dish instead of harmonizing.

Use high-quality olive oil – this is the backbone of the sauce, so choose a robust extra virgin olive oil with fruity or peppery notes; it will dramatically elevate the flavor profile.

Salt your pasta water generously – it should taste like the sea. This is the only chance to deeply season the pasta from within, making every bite flavorful, not just the coating.

Reserve pasta water like liquid gold – the starchy water is essential for emulsifying the sauce, helping the oil cling to the noodles and preventing it from feeling greasy or flat.

Balance with acidity and freshness – a final squeeze of fresh lemon juice and sprinkle of parsley brightens the dish, cutting through the richness and keeping the flavors alive until the last bite.

Spaghetti Aglio e Olio Recipe

Ingredients

1 pound dry spaghetti – your pasta base, cooked al dente for the perfect bite

1 teaspoon salt, divided – half for the boiling water, half for seasoning the sauce

1 whole garlic bulb (about 20 cloves), thinly sliced – the heart of the dish, for bold, aromatic flavor

¼ teaspoon freshly cracked black pepper – for a subtle kick of warmth

½ teaspoon red pepper flakes – adds heat and depth (adjust to your spice preference)

½ cup extra virgin olive oil – infuses the pasta with rich, savory flavor

½ cup grated Parmesan cheese – melts into a savory, umami-rich finish

1 tablespoon finely chopped fresh Italian parsley – for a burst of freshness and color

2 tablespoons fresh lemon juice – adds brightness and balances the richness

¼ cup reserved pasta water – helps emulsify the sauce and cling to each strand of spaghetti

Instructions

Boil the Pasta

Fill a large pot with water, season it with ½ teaspoon of salt, and bring to a boil.

Cook the spaghetti until al dente (firm to the bite), about 10 minutes.

Before draining, reserve ¼ cup of the starchy pasta water, then set the pasta aside.

Infuse the Olive Oil

In a wide, deep skillet over medium-low heat, warm the olive oil.

Add the thinly sliced garlic, black pepper, remaining ½ teaspoon of salt, and red pepper flakes.

Sauté gently for about 2 minutes, or until the garlic becomes golden and aromatic—be careful not to let it brown or burn.

Combine Pasta and Garlic Oil

Add the cooked spaghetti directly into the skillet with the garlic oil. Toss thoroughly until every strand is coated.

Finish the Sauce

Add grated Parmesan cheese, minced parsley, lemon juice, and a splash (2 tablespoons) of the reserved pasta water.

Toss again until the cheese melts and creates a light, silky sauce.

Add a bit more pasta water if needed to loosen the sauce.

Serve Immediately

Plate and serve hot, optionally topped with extra cheese, a drizzle of olive oil, or more parsley for freshness.

Important Notes When Making Spaghetti Aglio e Olio:

Avoid overcooking the pasta – the essence of this dish lies in pasta with a firm bite (al dente). Overcooked noodles will soak up the oil and lose their structure, leaving the dish heavy and unbalanced.

Do not burn the garlic – garlic that turns too dark becomes acrid and ruins the delicate harmony of the sauce. The moment it reaches a light golden color, add the pasta to stop further browning.

Use the right pan size – a wide, shallow skillet allows for better contact between pasta, oil, and garlic, ensuring every strand gets coated evenly.

Season progressively, not all at once – taste at each step. Pasta water, oil, cheese, and lemon juice all contribute saltiness; adding too much salt at the start can overwhelm the dish.

Serve immediately – this is a dish best enjoyed fresh from the pan. If it sits too long, the pasta absorbs the oil, making it dry and less vibrant in flavor.

How to Enjoy This Spaghetti Aglio e Olio Recipe After Cooking

Serve it piping hot – this dish shines brightest when eaten immediately. The garlic oil should still be silky and fragrant, coating every strand of pasta without clumping.

Twirl, don’t cut – use a fork (and spoon if you prefer) to twirl the spaghetti into a neat bite. This allows you to capture the full balance of pasta, oil, garlic, and parsley in one mouthful.

Enhance with simple sides – pair with crusty Italian bread to soak up the garlicky oil, or serve alongside a crisp green salad for freshness and contrast.

Elevate with pairings – a chilled glass of dry white wine (like Pinot Grigio or Sauvignon Blanc) or sparkling water with lemon enhances the citrusy brightness of the dish.

Add a finishing flourish – drizzle with a touch more extra virgin olive oil, sprinkle freshly grated Parmesan, or add a squeeze of lemon juice right before eating for an extra burst of flavor.

Savor the simplicity – take a moment to appreciate the minimalist beauty of this dish: just a few humble ingredients transformed into something deeply satisfying and comforting.

Frequently Asked Questions:

Can I use pre-minced garlic instead of fresh garlic cloves?

Freshly sliced garlic is strongly recommended because it infuses the oil with a more vibrant, aromatic flavor. Pre-minced garlic often has preservatives and a slightly bitter aftertaste when cooked.

How do I keep the garlic from burning?

Cook the garlic on medium-low heat and remove the pan from heat briefly if it starts browning too quickly. Burnt garlic can make the entire dish taste bitter.

What type of pasta works best for this recipe?

Traditional spaghetti is ideal, but linguine or fettuccine also work well because their flat surfaces allow the garlic oil to cling beautifully.

Is Parmesan cheese authentic in Spaghetti Aglio e Olio?

Classic Italian tradition does not always include cheese, but many modern versions add Parmesan or Pecorino for richness. It’s optional but adds depth and creaminess.

Can I adjust the spiciness of the dish?

Yes! Start with a small pinch of red pepper flakes and add more to taste. For a milder version, you can leave them out entirely without compromising the dish.

Should I salt the pasta water heavily?

Yes. The pasta water should be “as salty as the sea.” This step seasons the pasta from the inside out and reduces the need for excess salt later.

Do I need to reserve pasta water, and why?

Absolutely. The starchy pasta water is essential for emulsifying the garlic-infused oil, helping the sauce cling to each strand of spaghetti for a silky finish.

When should I add the garlic to the oil?

Add it once the oil is gently warmed, not hot. Starting on lower heat allows the garlic to release its fragrance without burning, creating a balanced, aromatic base.

Can I prepare the garlic oil ahead of time?

Yes, but it’s best made fresh. If you must prepare it in advance, store the infused oil in the fridge for up to 24 hours and gently reheat before tossing with pasta.

How do I keep the pasta from drying out while mixing?

Work quickly. Drain the pasta and immediately transfer it to the skillet with the garlic oil while still hot. This helps the flavors bind, and a splash of pasta water prevents dryness.
