Aglio e Olio is the magic of Italian cooking in one pan, turning just spaghetti, garlic, and good olive oil into a silky, garlicky dinner in about fifteen minutes. I make this on *those nights* when the pantry looks bare and the girls are starving, and it always feels a little fancy for how little it takes. It is as weeknight friendly as our bacon pesto pasta.
A splash of starchy pasta water is the secret that turns the garlic and oil into a glossy sauce that clings to every strand.

How to Make Aglio e Olio
- Boil the spaghetti in well salted water until al dente, following the package directions. Reserve one to two cups of pasta water before draining.
- In a large skillet, heat the olive oil over medium heat. Add the sliced garlic and red pepper flakes and cook until fragrant, about one to two minutes, being careful not to let the garlic burn.
- Toss the drained spaghetti into the skillet with the garlic oil, adding a splash of the reserved pasta water to help create a smooth sauce.
- Mix everything well, adding more pasta water as needed, until the pasta is evenly coated and glossy.
- Serve immediately, garnished with freshly chopped parsley and grated parmesan if desired.
Recipe Tips & Tricks
- Slice the garlic thinly. Thin, even slices cook gently and evenly without burning or turning bitter.
- Do not burn the garlic. Keep the heat at medium and pull it before it browns, since bitter garlic ruins the dish.
- Save plenty of pasta water. That starchy liquid is what turns the oil into a silky, clinging sauce.
- Salt the pasta water well. Since the sauce is so simple, well seasoned pasta is essential for flavor.
- Use good olive oil, since it is the backbone of the dish, just like the quality oil in our bacon pesto pasta.
- Serve it right away, as aglio e olio is best enjoyed hot and glossy straight from the pan.
Serving Ideas and Suggestions
Aglio e Olio is a beautiful meal all on its own, but it also makes a wonderful first course or side. Serve it with a crisp green salad and crusty bread to round out a simple, satisfying Italian dinner.

Aglio e Olio FAQs
Aglio e Olio is Italian for garlic and oil, the two main ingredients of this classic Roman pasta. The full name is spaghetti aglio e olio, meaning spaghetti with garlic and oil.
Dry aglio e olio usually means not enough pasta water. The starchy water emulsifies with the oil to create a glossy sauce, so add it a splash at a time while tossing until the pasta is silky and coated.
It is best made fresh and served right away, since the sauce can dry out as it sits. If you have leftovers, reheat gently with a splash of water or oil to loosen it back up.
Sauteed shrimp, grilled chicken, crispy pancetta, or even a fried egg on top all work beautifully. Add cooked protein at the end so it does not overwhelm the simple garlic and oil flavor.
No, but they add the signature gentle heat that balances the rich oil. You can leave them out for a milder dish, or add more for extra spice. The recipe is very forgiving.
Spaghetti is the traditional choice, but any long pasta like linguine, bucatini, or spaghettini works well. The long strands catch the garlicky oil best for that classic twirl.
