If there is one Italian pasta recipe that we make on constant rotation, it would have to be this one! Fast and flavorful like our easy pasta Amatriciana or even our pasta with ricotta and peas (soooo good!).
Spaghetti aglio e olio (literally "spaghetti, garlic, and oil") is one of Italy's great culinary tricks - a garlic and oil pasta so simple it almost dares you to mess it up, but so good you'll come back to it every week. It's the dish my Calabrian mother-in-law makes late at night with whatever's in the pantry.
It's the pasta I learned before I knew how to boil water properly. And once you learn the technique, it belongs to you forever.
I can't even remember when I first learned how to make it. It's one of the first recipes I made on my own. Since it is so simple to make, once you learn how to make it, you'll add this to your pasta repertoire.

What ingredients are in aglio e olio?
Here is all you need to make this classic Italian pasta dish (full printable recipe is below):
- Pasta: Use spaghetti, bucatini, linguine, fettuccine, or any long pasta you enjoy.
- Olive oil: Olive oil is the main feature of the sauce, so I highly recommend using a very good quality extra-virgin olive oil. Even if you get a small bottle, you'll notice the flavor difference.
- Garlic: Fresh garlic is best. You could even use garlic that bottled minced garlic. I used fresh and cut the cloves into big slices. If using fresh, you'll use between 5-10 cloves (depending on how big the cloves are and how much garlic you like...we used 6).
- Crushed red pepper flakes: When you get your hands on peperoncini (red hot chili peppers) at any produce market (depending if you're in the States, you could use another type of red hot pepper), grab them, and make this pasta! My Calabrian mother-in-law gives us jars of them that she preserves in Italy every summer (amazingly hot!). In place of fresh, use crushed red pepper flakes.
- Salt: I used sea salt for the garlic oil sauce (you could use kosher salt). I use coarse salt to salt the pasta water.
- Parsley: An optional topping is parsley. I only use fresh Italian parsley (no dried parsley). Chop up the leaves (not the stems).
How to make spaghetti aglio e olio?
Here's how to make classic spaghetti aglio e olio…(full printable recipe below)
Gather up the ingredients and get started with boiling the water.
While you're waiting for the water to boil, heat a large skillet with the olive oil.
Once the water is boiling, add the salt, add the spaghetti.
A few minutes after you have the pasta boiling, add the garlic slices to the heated oil and shake the pan or use a spoon to keep the garlic moving. Sauté the garlic until it is a nice light golden brown (should take 3-5 minutes).
Add in the hot pepper flakes (or peperoncino) and stir to combine with the garlic and oil.
Once the garlic reaches the light golden color, remove the pan from the heat while the pasta keeps cooking. Stir in the parsley (you could reserve some to toss on top at the end, it's up to you).
Cook the pasta until it's just before al dente (set a timer for 1 minute less than the cooking time on the pasta instructions so you don't forget ). Reserve a ½ cup of starchy pasta water.
Add the pan back onto medium-high heat. Drain the pasta and immediately add to the pan with the garlic oil. Add in the reserved pasta water and toss to combine.
Plate up the pasta and add some more fresh chopped parsley and pepper flakes (if you like).
Tips for the best aglio e olio:
- Golden - not dark - garlic. Burnt garlic is bitter and ruins the dish. Pull it off heat the second it turns amber.
- Never rinse the pasta. That starchy coating is what emulsifies with the oil to make the sauce.
- Pasta water is the secret. The magic happens when starchy water, olive oil, and pasta toss together off-heat.
- Finish cooking the pasta in the sauce. Drain at 1 minute before al dente - the last minute of cooking happens in the pan.
- Use enough garlic. Italians don't mess around - 6 cloves minimum for a pound of pasta.
- Don't add cheese. Traditional aglio e olio is served without parmigiano. The oil is the star.
Common Mistakes to Avoid
- Burning the garlic → bitter pasta. Keep heat on medium, stir constantly.
- Under-salting the pasta water → bland pasta, no amount of sauce can fix it.
- Draining all the pasta water → no emulsion, just oily spaghetti.
- Using cheap olive oil → flat flavor. The oil is the sauce.
- Adding the garlic to cold oil → the garlic will absorb too much oil and get soggy.
- Rinsing cooked pasta → washes away the starch that bonds the sauce.
Aglio e Olio vs. Cacio e Pepe vs. Carbonara
All three are iconic Italian pasta dishes built on 3-4 pantry ingredients - but they're very different:
- Aglio e Olio - garlic, olive oil, chili flakes. No cheese, no meat.
- Cacio e Pepe - Pecorino Romano and black pepper. No garlic, no oil.
- Carbonara - egg yolks, Pecorino, guanciale, black pepper. Rich and creamy.
How to Store and Reheat
- Freezer: Not recommended - the texture suffers.
- Fridge: Leftovers keep in an airtight container for up to 2 days.
- Reheat: Warm in a skillet over medium heat with a splash of water and a drizzle of olive oil to bring the sauce back.
What Is Aglio e Olio?
Aglio e olio (pronounced AH-lee-oh eh OH-lee-oh) is a traditional Italian pasta dish from Naples, made with four ingredients: spaghetti, extra-virgin olive oil, garlic, and crushed red pepper flakes. In Italy it's often called aglio, olio e peperoncino - the peperoncino being the spicy red chili pepper that gives it its kick.
It is the definition of cucina povera - peasant cooking - and one of the purest expressions of Italian food philosophy: four beautiful ingredients, perfectly cooked, needing nothing else.
What is a Spaghettata di Mezzanotte?
In Italy spaghetti aglio e olio is also called spaghetti aglio olio e peperoncino, or the spaghettata di mezzanotte. Peperoncino is the red hot chili peppers.
There were many summers when I was living in Italy that my friends and I would enjoy a nice spaghettata di mezzanotte-"midnight spaghetti. That is the Italian after-party tradition of enjoying a very garlicky and very spicy plate of spaghetti after being out with friends.
Since it's super easy to make, very flavorful, and has a kick of spice, it's the perfect no-fuss pasta to make with friends.
Is Aglio e Olio Authentic Italian?
Yes - 100% authentic. Aglio e olio originated in Naples and became beloved across all of southern Italy, particularly in Rome where it's considered part of the classic Roman pasta tradition alongside cacio e pepe, carbonara, amatriciana, and pasta alla gricia.
Italians eat it for quick weeknight dinners, as the famous spaghettata di mezzanotte (midnight spaghetti) after a night out with friends, and as a simple primo when tomatoes aren't in season.
What to serve aglio e olio with?
- Authentic and Easy Italian Bruschetta: This classic Italian appetizer features toasted bread slices topped with a mixture of chopped tomatoes, extra-virgin olive oil, garlic, and fresh basil. It's a simple yet flavorful dish that can be customized with various toppings like mozzarella, red onion, or pesto .
- Best Marinated Mushrooms: This recipe involves marinating mushrooms in a mixture of lemon juice, white wine vinegar, olive oil, garlic, herbs, and red pepper flakes. It's an easy and refreshing appetizer that can be served in salads, antipasto, or pasta salad, or enjoyed straight from the jar .
- Easy Baked Brie in Puff Pastry With Cranberries: This appetizer consists of a wheel of brie cheese wrapped in puff pastry, topped with cranberry sauce, and baked until the pastry is golden and the cheese is melted. It's garnished with toasted almonds, honey, and fresh cranberries for added flavor and texture .
Variations/Substitutions
- Add protein: Shrimp, clams, or calamari are classic Italian additions.
- Whole grain or gluten-free: Swap in your favorite long pasta.
- Extra heat: Add a pinch of cayenne or Calabrian chili paste.
- Herby: Finish with fresh basil or a squeeze of lemon.
- Anchovy version: Melt 2-3 anchovy fillets into the oil before adding garlic - an authentic southern Italian variation.

Please keep in mind that the nutritional information presented below is an approximation and may vary depending on the exact ingredients used.
Notes
- Pasta: I have only had this dish with spaghetti. If you want to stay authentic, use only spaghetti. Choose a very good quality spaghetti. If you can find bronze cut, that would be even better and will cook up nice and al dente.
- Olive oil: Use a very good quality extra-virgin olive oil. It is the base for the sauce, so keep that in mind, as it will make the sauce taste even better.
- Garlic: Adjust the amount of fresh garlic to your taste. You could slice it or mince it. The minced garlic will brown very quickly, so you'll have to carefully watch it while you cook it in the hot olive oil.
- Hot pepper: Adjust the heat to your liking. If you don't like spicy, do not add in any hot pepper flakes. My kids do not like spicy, so I only add it in for those that do.
- Add-in: This is a really great pasta dish to add seafood to. Shrimp or calamari would be great.
- Leftovers: Any leftovers will stay fresh in the fridge for a couple of days in an airtight container.
I made this and it was so simple but full of flavor. The garlic and olive oil really shine!
Sometimes it's the simplest things that are the best and most satisfying. This dish hits all the points. It's easy to make, flavorful, and even better leftover.
This is the ultimate "I have nothing in the fridge" meal that actually tastes like a restaurant dish. It’s so simple, but the garlic and oil combo is just classic. I love adding a little extra red pepper flakes for a bit of a kick!
I love your cooking methods. This is just how my mom used to make pasta -- the same ingredients and methods: salted water, simple prep and ingredients, retain pasta water. Perfect every time. Simple pasta is the best, and fried garlic is sublime! 😉
I made this with some seared salmon. Chef's kiss!
This is yummy. I made it as-is, but I'm already thinking of what I'll add to it next time.
Just yummy! I added some pan-seared shrimp. It was so good.
Agreed - this goes in the rotation, year round. Wonder why you "never" add Parmesan cheese. To me, the partnership of olive oil and Parmesan is one of the culinary matchups made in heaven, along with onions, green peppers and celery, and cheese and chutney. Parmesan is, of course, quite salty, making it unnecessary to put all that salt in with the spaghetti. Do you have a specific reason to eschew the cheese ? Is there some unwritten rule in Italian cooking that I am unaware of ?
Hello Christophe- Great question and you are not alone in thinking olive oil and cheese feel like a perfect pairing.
First, a small but important detail. I do not use Parmesan because Parmesan is not the same thing as Parmigiano Reggiano. What most people call Parmesan, especially outside Italy, is usually a generic grated cheese with additives. True Parmigiano Reggiano is a protected Italian DOP cheese aged 12 to 36 months, with a much deeper and nuttier flavor. They are completely different products.
Now to the dish itself.
Aglio olio e peperoncino comes from Naples and Campania and was created as a simple pantry pasta using garlic, olive oil, chili, parsley, pasta water, and salt. Traditionally, there is no cheese.
The reason is flavor balance. This pasta is meant to be light, spicy, and aromatic. The olive oil and garlic are supposed to shine. Adding Parmigiano or Pecorino changes the entire profile, making it richer and heavier and softening the sharpness of the garlic and chili.
There is also a classic Italian rule that you generally do not add cheese to olive oil based pasta sauces. Instead, Italians rely on properly salted pasta water for seasoning. Parmigiano Reggiano itself contains about 1.6 to 1.8 grams of salt per 100 grams, so adding it also changes the salt balance of the dish.
As for regions that add cheese, you will not find Parmigiano or Pecorino in traditional aglio olio e peperoncino in Naples or Campania.
However, some modern cooks do sprinkle Parmigiano or Pecorino on top at the table as a personal preference. That is not traditional, but people absolutely do it.
There is also a similar southern Italian pasta called spaghetti alla carrettiera, especially common in Sicily, which combines olive oil, garlic, chili, parsley, and Pecorino. That is a different regional dish, not classic aglio olio.
So the short answer is this. Traditional aglio olio stays cheese free. If you love adding Parmigiano or Pecorino after plating, go for it. Your kitchen, your rules. Just know that once you add cheese, you have technically turned it into a different dish. Still delicious. Just not classic aglio olio. Hope that helps!
Truly my favorite pasta! I finally got a good recipe! THANK YOU!
