↓ The ingredients ↓ The steps

Aglio, Olio e Peperoncino is the unsung hero of late-night Italian cooking, proving that simplicity is often the ultimate sophistication. Relying entirely on technique rather than a long list of ingredients, this minimalist dish is created by slowly coaxing the aromatic oils from fresh garlic and spicy dried chilies into quality olive oil. By emulsifying that fragrant oil with hot, starchy pasta water, you create a rich, glossy sauce out of almost nothing.

Ingredients

Instructions

  1. 1Smash the Garlic
    Hands pressing down firmly to smash fresh garlic cloves on a wooden cutting board.

    Place the raw garlic cloves onto a wooden cutting board. Using the heel of your hand, press down firmly to smash the cloves, which will help loosen the skins and make them easier to peel.

    Tip: Smashing the garlic first not only makes peeling effortless but also begins to release its aromatic oils early in the prep process.
  2. 2Remove the Garlic Germ

    Take the peeled garlic cloves and carefully slice them in half lengthwise. Pluck out and discard the small green germ found inside the center of each clove.

    Tip: Taking the time to remove the inner green germ ensures your pasta wont have a harsh or bitter aftertaste.
  3. 3Mince the Garlic

    Finely mince the halved garlic cloves into small, uniform pieces on your cutting board. A fine chop allows the garlic flavor to infuse smoothly and quickly into the olive oil later.

    Tip: Try to keep the minced pieces as even as possible so they cook at the same rate and dont burn in the pan.
  4. 4Chop the Chilies

    Grab your dried red chilies and use a sharp knife to chop them into small flakes and pieces. This will provide the signature spicy kick for your Aglio Olio e Peperoncino.

    Tip: If you are sensitive to heat, you can shake out and discard the seeds from the chilies before chopping them.
  5. 5Salt the Boiling Water
    Hand sprinkling salt into a clear glass pot of bubbling boiling water over a portable stove.

    Bring a pot of water to a rolling boil. Add a generous amount of salt to the water to properly season the pasta as it cooks. Stir well to ensure the salt is fully dissolved before adding the spaghetti.

    Tip: Do not skimp on the salt. The pasta water should taste slightly salty like the sea to properly flavor the spaghetti from the inside out.
  6. 6Boil the Spaghetti
    Hands dropping a bunch of dry spaghetti vertically into a clear glass pot of boiling water.

    Once your pot of salted water reaches a rolling boil, add a handful of dry spaghetti. Because this pasta will finish cooking in the pan, it only needs to boil for a short time, roughly 5 minutes.

    Tip: Gently push the spaghetti down as it softens so it all submerges and cooks evenly without breaking the noodles.
  7. 7Heat the Olive Oil

    Place a large, cold frying pan on the stove and pour in a generous amount of high-quality olive oil. Heating the oil gently allows the aromatics to infuse properly without burning.

    Tip: Aglio e Olio relies on very few ingredients, so using a good quality extra virgin olive oil is essential for the best flavor.
  8. 8Infuse the Garlic
    Minced garlic being scraped off a chefs knife into a skillet of warm olive oil.

    Add the finely minced garlic into the pan with the olive oil. Keep the heat on a low setting so the garlic gently sizzles and slowly infuses the oil, turning a light golden color.

    Tip: Watch the garlic closely. If it browns too quickly or burns, it will introduce a bitter taste to the entire dish.
  9. 9Add the Dried Chilies
    Fingers pushing chopped dried red chilies off a knife into a pan with sizzling minced garlic.

    Once the garlic is fragrant and just starting to turn golden, add the chopped dried red chilies into the pan. Mix the ingredients evenly to release the spicy oils from the peppers into the base.

    Tip: Adjust the amount of dried chili based on your spice preference. Remember that the seeds carry most of the heat.
  10. 10Emulsify with Pasta Water
    A white ladle pouring hot starchy water into a pan containing sizzling garlic, oil, and chilies.

    Carefully pour a ladle of the hot, starchy pasta cooking water directly into the pan with the garlic and chili oil. Swirl or mix the pan to help the water and oil emulsify into a smooth sauce and stop the garlic from cooking further.

    Tip: This starchy water is liquid gold; it binds the oil into a cohesive, creamy sauce that will evenly coat the pasta.
  11. 11Toss the Spaghetti
    Long strands of spaghetti being dropped into a pan of simmering garlic and chili oil sauce.

    When the spaghetti is still slightly hard (about 5 minutes of cooking), transfer it directly from the boiling water into the pan with the garlic and chili sauce. Add another ladle of pasta water and toss thoroughly to let the pasta finish cooking in the flavorful sauce.

    Tip: Transferring the pasta directly, rather than draining it in a colander, brings extra starchy water into the pan, which thickens the sauce beautifully.
  12. 12Add More Pasta Water
    A hand pouring a ladle of pasta water into a skillet filled with spaghetti, garlic, chilies, and olive oil.

    Pour another ladle of the reserved starchy pasta water into the pan. The starchy water is crucial for creating a creamy, emulsified sauce when combined with the olive oil and garlic.

    Tip: Add the water gradually. You want enough to coat the pasta evenly without making it soupy.
  13. 13Emulsify the Sauce
    Metal tongs tossing spaghetti in a skillet with oil and red chilies, creating a glossy sauce.

    Using tongs, vigorously toss and stir the spaghetti in the pan. The continuous agitation helps emulsify the olive oil and starchy pasta water into a thick, glossy sauce that coats every strand perfectly.

    Tip: If the sauce looks too oily and separated, add a splash more pasta water and keep tossing vigorously.
  14. 14Add Fresh Parsley
    A hand sprinkling freshly chopped green parsley over a pan of glossy spaghetti.

    Sprinkle a handful of finely chopped fresh parsley over the coated pasta. The parsley adds a bright, fresh flavor and a pop of green color that balances the richness of the garlic and olive oil.

    Tip: Add the parsley at the very end off the heat to preserve its delicate fresh flavor and vibrant color.
  15. 15Plate the Pasta
    Tongs lifting and twirling spaghetti aglio e olio onto a bright orange serving plate.

    Use tongs to lift a generous portion of the spaghetti. Twirl the pasta around the tongs and gently slide it onto a plate to create a neat, attractive mound. Make sure to scoop up any remaining garlic, oil, and chilies from the pan to spoon over the top.

    Tip: Twirling the pasta gives it height and makes for a beautiful, restaurant-quality presentation.

Storage & Reheating

Refrigerator
Up to 3 days
Store leftovers in an airtight container. Note that the noodles will absorb the oil over time, making it less saucy.
Reheating
5 min
Reheat gently in a skillet over low heat with a splash of water to rehydrate the emulsion. Microwaving is not recommended as it causes the oil to separate.

Frequently Asked Questions

An oily sauce means the oil and water havent emulsified properly. You likely need more starchy pasta water and more vigorous tossing in the pan to bind them together.
For Aglio e Olio, fresh garlic is strictly required. The dish relies entirely on infusing the extra virgin olive oil with fresh, slowly toasted garlic.
Garlic turns bitter if it burns. Ensure you are cooking it over low heat just until it turns a pale golden color. Removing the inner green germ before mincing also helps eliminate natural bitterness.
