Introduction

This deceptively simple pasta dish from Naples, known as aglio e olio (meaning “garlic and oil”), is a staple in Italian home kitchens. With just a few pantry essentials, you can craft a dinner that’s both comforting and impressive. The technique lies in gently toasting sliced garlic in extra-virgin olive oil and tossing it with perfectly cooked spaghetti. The result is a dish with a silky, aromatic sauce, flecked with parsley and finished with a shower of Parmesan cheese for richness and depth.

Ingredients

All ingredients in this classic Italian recipe are easy to source and highly affordable, making it an ideal quick weeknight dinner.

  • 1 pound (450g) uncooked spaghetti
  • ½ cup olive oil (preferably extra-virgin)
  • 6 cloves garlic, thinly sliced
  • ¼ teaspoon red pepper flakes (add more for extra heat)
  • Salt and freshly ground black pepper, to taste
  • ¼ cup chopped fresh Italian parsley
  • 1 cup finely grated Parmigiano-Reggiano cheese (Parmesan)

These quantities yield approximately four servings—the ideal amount for a family-style meal or an intimate dinner gathering.

Step-by-Step Instructions

Timing and technique are everything in Spaghetti Aglio e Olio. Follow these detailed steps to achieve pasta perfection:

  1. Prep the Ingredients: Gather and measure all ingredients. Slice garlic thinly to ensure it distributes evenly and infuses the oil.
  2. Cook the Pasta:
    • Bring a large pot of lightly salted water to a rolling boil.
    • Add the spaghetti and cook, stirring occasionally, until al dente—typically 10 to 12 minutes.
    • Reserve ½ cup of pasta cooking water before draining.
    • Drain the spaghetti and transfer it to a large mixing or serving bowl.
  3. Infuse the Olive Oil:
    • While the pasta cooks, add olive oil and sliced garlic to a cold skillet.
    • Turn the heat to medium and gently toast the garlic, stirring frequently. The goal is a golden brown—this can take up to 10 minutes.
    • If the oil starts to bubble too vigorously, reduce the heat to medium-low to prevent burning.
    • Remove the pan from heat as soon as the garlic is fragrant and golden.
  4. Toss the Pasta:
    • Sprinkle red pepper flakes, salt, and freshly ground black pepper onto the hot spaghetti.
    • Pour in the hot olive oil and toasted garlic.
    • Add the chopped parsley and half of the grated Parmigiano-Reggiano.
    • Toss thoroughly until the pasta is well coated. If needed, add a splash of reserved pasta water to achieve a silky consistency.
  5. Serve:
    • Plate the pasta and shower with the remaining Parmigiano-Reggiano.
    • Serve immediately while piping hot.

Tips & Tricks for Perfect Aglio e Olio

  • Use Quality Olive Oil: The oil is the backbone of this dish; choose a good extra-virgin olive oil for best flavor.
  • Control the Heat: Infuse the oil over medium or medium-low heat. Garlic must turn golden, never brown or burnt, or it will taste bitter.
  • Timing is Everything: Start the oil infusion once the pasta is in the water to sync up the timing.
  • Salt Generously: Season pasta water well—this is your only chance to thoroughly season the noodles.
  • Don’t Overcrowd the Pan: Spread out the garlic slices so they toast evenly.
  • Customize the Heat: Adjust the amount of red pepper flakes to suit your preferred spice level.
  • Finish with Pasta Water: Use reserved pasta water to ensure the sauce clings to the spaghetti and gives a glossy finish.
  • Cheese is Optional—but Delicious: While traditionalists may skip the cheese, Parmigiano-Reggiano delivers extra richness and depth.

Recipe Variations

This Italian staple is endlessly adaptable. Try these creative spins on the classic:

  • Add Protein: Toss in sautéed shrimp or shredded rotisserie chicken for a heartier meal.
  • Enhanced with Lemon: Add a splash of fresh lemon juice or zest for brightness.
  • Vegetable Boost: Stir in baby spinach, sautéed mushrooms, or blistered cherry tomatoes before serving.
  • Bread Crumb Topping: Sprinkle toasted bread crumbs for crunch and rustic flair.
  • Other Pasta Shapes: Swap spaghetti for linguine, fettuccine, or bucatini—adjust cooking time as needed.
  • Nutty Twist: Add a handful of toasted hazelnuts or walnuts for flavor and texture (see “Aglio e Olio alla Fremont” variation).
  • Bottarga Finish: For a gourmet uptick, garnish with shaved bottarga (cured fish roe) for briny, umami notes.

Serving Suggestions

Spaghetti Aglio e Olio shines as a stand-alone main course but pairs beautifully with:

  • Simple green salads: Toss arugula, baby spinach, or mixed greens with lemon and olive oil.
  • Roasted or steamed vegetables: Such as broccoli, asparagus, or zucchini.
  • Crusty Italian bread: Perfect for mopping up excess oil and garlic.
  • Light Italian wines: Pinot Grigio, Soave, or a young Chianti complement the dish nicely.

Frequently Asked Questions (FAQs)

Q: Can I make Spaghetti Aglio e Olio ahead of time?

Q: Is cheese traditional in Aglio e Olio?

A: Purists may skip the cheese, but many home cooks and restaurants add freshly grated Parmigiano-Reggiano for richness.

Q: Can I make this dish gluten-free?

A: Yes! Substitute with your favorite gluten-free spaghetti and follow the same method.

Q: What type of olive oil should I use?

A: Use the best quality extra-virgin olive oil you can afford. Its flavor is central to the dish.

Q: How do I prevent my garlic from burning?

A: Start with a cold pan and heat the oil and garlic together; keep the heat medium to medium-low and stir frequently.

Q: Can Spaghetti Aglio e Olio be made vegan?

A: Absolutely! Simply omit the cheese or use a plant-based alternative.

Expert Tips for Success

  • Garlic Slicing: Slice garlic as evenly as possible for consistent cooking; a mandoline or sharp knife helps achieve paper-thin slices.
  • Pasta Water Magic: The starch in reserved pasta water gives the sauce its characteristic silkiness—don’t skip it.
  • Don’t Crowd the Garlic: Overcrowded garlic in the pan will cook unevenly. For larger batches, use a bigger skillet and monitor closely.
  • Parsley Freshness: Chop parsley just before adding for maximum color and bright, herby flavor.
