Classic Spaghetti Aglio e Olio is easy to make with just 4 simple ingredients (spaghetti, olive oil, garlic and crushed red pepper flakes), it comes together in 20 minutes, and it is always such a winner.
Guys, have you made spaghetti aglio e olio before?
Barclay and I saw this classic pasta dish on menus everywhere during our trip to Rome and Naples a few years ago, and have enjoyed perfecting our version of it at home ever since. It’s ultra-easy to make with just four ingredients — garlic (aglio), olive oil (olio), spaghetti, and a hint of red chile peppers. But while Italians typically use chopped fresh red chiles (peperoncini) in this dish, fresh red chile peppers can be a bit harder to find here in Spain and elsewhere around the world. So we typically just use a generous pinch of crushed red pepper flakes from our pantry.
That said, I learned on our trip to Italy that I had actually been making this dish wrong in years past, when I used to just toss spaghetti in the garlicky oil once it had finished cooking. The key to creating a gorgeous, glossy, non-greasy sauce is to create an emulsion with the garlicky oil and that magical starchy pasta water (the key to most good pasta sauces!). All you have to do transfer the pasta and a half-ish cup of that hot starchy pasta water directly into the pan of garlicky oil one minute before the pasta is done cooking. Then while you toss the pasta, all of that heat and starch will help the garlic oil emulsify into a beautiful glossy sauce, while the pasta soaks up some extra garlicky flavors as it finishes cooking.
It’s a simple tweak that’s guaranteed to kick your aglio e olio up a delicious notch, and it could not be easier. So grab some garlic and olive oil, and let’s make this classic pasta dish together!

Spaghetti Aglio e Olio Ingredients
First, a brief chat about the ingredients needed to make spaghetti aglio e olio (pronounced “ah-lee-oh eh oh-lee-oh”)…
- Spaghetti: Or linguine, fettuccine, or any other shape of pasta noodle you prefer.
- Olive oil: Since olive oil is the main ingredient in this sauce, I really recommend using the best-quality extra virgin olive oil you can find. It will make a difference!
- Garlic: I admittedly like tons of garlic in this pasta (like, closer to 10-12 cloves). But it is traditionally made with between 4-8 cloves. So you do what sounds best to you!
- Crushed red pepper flakes: Traditional spaghetti aglio e olio is made with fresh peperoncini (red hot chile peppers) that are commonly found throughout Italy. But since they are harder to find in other countries, I have written this recipe using dried crushed red pepper flakes, which we will simmer in the olive oil to bring out their best flavor.
- Optional garnishes: The two most popular toppings for this classic Italian dish are finely-minced fresh parsley and/or freshly-grated Parmesan. I love adding both, but they are totally optional.
How To Make Spaghetti Aglio e Olio
To make classic spaghetti aglio e olio, simply…
- Cook the spaghetti. Cook the spaghetti in a generously-salted pot of boiling water until it is just one minute shy of being al dente.
- Sauté the garlic. Meanwhile, about 3 minutes after you add the pasta to the boiling water, heat the olive oil in a large sauté pan over medium heat. Add the sliced garlic and crushed red pepper flakes and sauté for 3 to 5 minutes, or until the garlic is lightly golden.
- Toss the pasta in the sauce. Once the pasta is ready to go, use tongs to transfer the pasta immediately to the sauté pan, along with 1/2 cup of the hot starchy pasta water. Toss the pasta continuously until it is evenly coated in the garlic sauce. If the sauce looks a bit too dry, add in another 1/4 cup of the starchy pasta water.
- Taste and season. Give the pasta a quick taste add an extra pinch of salt and/or crushed red pepper flakes if needed.
- Serve. Serve immediately while it’s nice and hot, garnished with any toppings that sound good.
A few important tips:
- Have all of your ingredients ready to go. Things move fairly quickly once the pasta begins to cook, so I recommend having all of your ingredients laid out, chopped and ready to go.
- It’s important that the garlic not burn. If turns lightly golden before the pasta is ready to go, just remove the pan from the heat until it’s time to add the pasta.
- Don’t forget to salt that pasta water! You’ve heard me say it before, but this is the main time that you really get to season the pasta itself. So be sure to add a generous helping of sea salt to the water.
Recipe Variations
There are all sorts of variations that you can make on this recipe! For example, feel free to…
- Add anchovies: This is another popular option in Italy! Finely chop up a few anchovies and sauté them in the garlic sauce to add some extra salty umami flavor to this dish.
- Add basil: This pasta would also be delicious sprinkled with chopped fresh basil instead of parsley, if you happen to have some on hand.
- Add extra crushed red pepper flakes: If you would like your pasta to have more heat, feel free to double (or even triple!) the amount of crushed red pepper flakes.
- Use minced or smashed garlic: If thin slices of garlic aren’t your thing, you are welcome to mince (or press) the garlic instead. Or you can just smash the whole garlic cloves and sauté them to infuse the olive oil, then remove and discard the cloves before adding the pasta to the sauce.
- Add a protein: Of course, you are also welcome to add any cooked protein (such as chicken, shrimp, steak, or pork) to your spaghetti.
- Add veggies: And/or you can add in any cooked veggies that you love too (such as broccoli, mushrooms, bell peppers, onion, etc).

Add the sliced garlic and crushed red pepper flakes and sauté for 3 to 5 minutes, or until it is lightly golden. (It's very important that the garlic not burn.

Looks delicious will have to try it 😋
I add a pint of cherry or grape tomatoes sliced in half, and serve with parmesan cheese. Delicious!
Perfection! Your directions were spot on. A simple yet amazing dish that will now be a regular for us! Thank you!!!
Thank you so much for sharing your recipe and memories of it! I have been making this for years, and always thinly slice the garlic instead of chopping it. My dad used to order this dish almost every Friday night for 3 years at Riva’s Italian restaurant in Houston back in 1977. Wonderful memories of him picking up a slice of garlic bread and asking “Who wants a dunk?”, meaning into the awesome garlic sauce left in his bowl! No one refused!! LOL What really caught my eye was the optional addition of anchovies. It is freaking ahhmazing!! My dad would have loved that addition, but he passed in March this year. Now I have made this dish with anchovies 4 times!! Thank you again❣
I only added 2-3 tableSpoons of italian breadcrumbs to the olive oil+hot red pepper flakes+garlic to toast for 1-2 min and that makes the tasty oil mixture kinda stick to the spaghetti when everything is mixed at the end:) served with blanched broccoli rabe on the side. Great east and very tasty recipe! Thank you!
I am going to make this… but I have leftover spaghetti , will this still be ok?
Excellent and very easy! I told my husband that I was cooking today and he cracked up laughing… he loved the pasta and so did I!!!
Could you add a splash of dry white wine for the acid to help emulsify the sauce?
This is the best aglio olio recipes ever
Thank you 😊
I grew up on this as my mom is from Italy and it was a staple in our house. This is the most authentic recipe you will find. Add the extra cloves of garlic he recommends. Do be afraid to experiment by adding diff veggies, like…mushrooms, peppers, broccoli, asparagus, etc. And load it up with parm or romano cheese.
