Spaghetti Aglio e Olio is one of purest pasta dishes—nothing hidden, no shortcuts, no heavy sauces. Everything depends on technique: gently toasted garlic, balanced heat from chili, and properly salted pasta water. With just a few ingredients, every step matters. It’s fast, economical, and a perfect example of how little you need to cook something excellent.

Ingredients

  • 8 oz spaghetti
  • 4 tbsp extra-virgin olive oil
  • 4–6 garlic cloves, thinly sliced
  • 1/2–1 tsp red pepper flakes (adjust to heat preference)
  • Salt, to taste
  • 1/4 cup chopped fresh parsley
  • Reserved pasta water (very important)
  • Optional: grated Parmesan or Pecorino (not traditional)

Directions

1. Boil the pasta
  • Bring a large pot of water to a rolling boil.       
  • Salt heavily—this is your primary seasoning. Water should taste like the sea.   
  • Add spaghetti and cook until al dente.   
  • Reserve at least 1 cup of pasta water before draining.
2. Prep the aromatics
  • Peel the garlic and slice it thinly and evenly.
  • Thin slices give you garlic flavor without burning.   
  • Chop fresh parsley and set aside.
3. Heat the olive oil
  • In a large skillet, add the olive oil and warm it over medium heat.
  • Oil should shimmer but not smoke; this ensures slow, even garlic toasting
4. Toast the garlic
  • Add the sliced garlic to the oil.
  • Cook slowly, stirring frequently, until the garlic turns light golden.
  • Do not let it get dark brown—once burnt, it becomes bitter and ruins the dish.
  • Lower heat if it browns too quickly
5. Add chili flakes
  • Add red pepper flakes to the garlic oil.
  • Stir for 20–30 seconds to bloom the spices.
  • You should smell the chili releasing flavor into the oil.
6. Combine pasta with the oil
  • Add drained spaghetti directly into the skillet.   
  • Toss immediately so every strand is coated in the garlic-chili oil.
7. Emulsify the sauce
  • Add a splash of reserved pasta water (2–4 tablespoons to start).   
  • Toss or stir vigorously.   
  • The starch in the pasta water binds with the oil, creating a silky, glossy sauce instead of greasy separation.     
  • Add more water as needed until the pasta is glossy and lightly sauced.
8. Add parsley and final seasoning
  • Stir in chopped parsley.   
  • Taste and adjust seasoning—add salt if needed or extra chili if you want more heat.
9. Rest briefly
  • Let the pasta sit off heat for 1 minute so the flavors settle and the sauce clings better.
10. Serve
  • Plate immediately while hot.
  • Optional: top with grated cheese, though it’s not traditional.
  • Drizzle a final teaspoon of olive oil for richness if desired.
