- Kosher salt - Salting the pot of boiling water helps to flavor the pasta and elevates any pasta dish.
- Spaghetti - Make sure to use a good quality dried spaghetti as it really does make a difference and tends to hold sauce better too.
- Extra virgin olive oil - For sauteeing the garlic and red pepper flakes. Additional oil is stirred through the assembled dish just before sprinkling with Parmesan and parsley.
- Garlic - For aromatic depth of flavor.
- Red pepper flakes - Offers a lovely, subtle warmth without being spicy. Feel free to adjust, as desired. (We can't stop eating this Aleppo Pepper! We're shaking it on everything! It's a game-changer.)
- Parsley - Use flat-leaf parsley, minced. It's optional, but I love the color and flavor it gives the dish as a garnish.
- Pasta water - This starchy reserved pasta water creates the base of the sauce without diluting flavor.
- Parmesan cheese - Sprinkled over the completed dish before serving. Adds a touch of decadence to this otherwise very simple pasta recipe. Always use freshly grated cheese for best flavor.
🗒 Instructions
This is an overview of the instructions for the Spaghetti Aglio Olio and Peperoncini recipe. Full instructions are in the recipe card at the bottom of the page.
- Salt a pot of boiling water. Cook the dried spaghetti until it’s just shy of al dente. That’s about 1 minute less than the package says.
- Reserve ½ cup of pasta water and set aside.
- Add 6 tablespoons of oil to a large skillet.
- Add the garlic and red pepper flakes (if using).
- Cook over medium heat (a gentle sizzle) for about 5 minutes until the garlic is very lightly golden. , about 5 minutes.
- Transfer the drained pasta to the skillet with the reserved pasta water. Increase the heat to high, and cook, stirring and tossing rapidly, until a creamy, emulsified sauce forms and coats the noodles.
- Remove from heat, and stir in the remaining oil. Sprinkle with parsley and Parmesan cheese (if using).
- Give the pasta a good stir. Mix in the parsley and cheese well. Serve right away for the best taste and texture.
🥫 Storage
Store leftover spaghetti aglio e olio in an airtight container. Keep it in the fridge for 3 to 5 days. You can also freeze it for up to 3 months.
Reheat in a pan over medium-low heat with a splash of broth or water to loosen the pasta and sauce. Add a squeeze of lemon juice to the reheated garlic-and-oil pasta. It will brighten the flavor. Garnish with extra Parmesan before serving, if you’d like.
📚 Variations
- You can add browned, drained ground beef or pork. Ground turkey works great, too. Try crispy bacon pieces or Italian sausage for a hearty twist on this pasta all’aglio.
- For an extra veggie boost, toss this olive oil pasta with sautéed mushrooms, wilted spinach, sun-dried tomatoes, or sliced bell peppers.
- For a spicy garlic spaghetti recipe, add extra red pepper flakes. You can also experiment with chili powder or cayenne pepper, but don't be heavy-handed. You can always mix in more once the dish has been assembled, but you can't adjust it if you add too much in the beginning.
- Use other types of pasta as an easy way to adapt this dish. Make sure to follow the cooking time on the packaging directions.
👩🏻🍳 Tips
- Adding starchy pasta water to the skillet with garlic and oil is key.It helps emulsify the sauce, so it turns creamy and not greasy.
- The sauce achieves a rich and fragrant flavor by infusing the oil with the garlic. Adjust the heat in the skillet to reach a gentle sizzling, but be careful not to burn the garlic!
- I don’t recommend swapping pasta water for plain water or low-sodium broth. You need that starch to thicken the sauce. It also helps create that silky, vellutata finish.
- Since the spaghetti will keep cooking in the hot skillet, boil it a bit less than al dente. Otherwise, you will end up with mushy pasta.
- Use a large enough skillet or cast-iron pan to stir and toss the pasta with garlic sauce.
- Work quickly once you've added the pasta and reserved pasta water to create an emulsified sauce that coats all of the pasta. Have your parsley and Parmesan cheese prepared beforehand so that your attention is not elsewhere.
- Always shred your cheese from a block as it melts much better than pre-shredded cheese and also tastes better!
🤔 FAQs
The secret is the pasta water. The starch helps emulsify the olive oil, creating a silky sauce instead of a greasy one. Toss the pasta vigorously while adding the reserved pasta water.
The sauce is ready when it reduces to a creamy coating on the noodles.
Not a problem. Simply add a little more pasta water to return it to the creamy coating you're after. If your sauce appears too oily, it's usually an indication of not enough pasta water.
Technically, this recipe is the same as aglio, olio e peperoncino. I just added red pepper flakes to the garlic-infused oil. That said, traditional aglio, olio e peperoncino calls for spicier additions, such as chili pepper. The red pepper flakes add a warm, gentle heat without overpowering the garlic-and-oil flavor.
Spaghetti is traditional, but linguine or spaghettoni also work beautifully. Bronze-cut pasta is especially good because its rough surface helps the sauce cling to every strand.
Absolutely! Traditional aglio e olio is often served without cheese. Parmesan is a delicious optional finishing touch.
Choose a high-quality extra-virgin olive oil, since it's the star of the dish. A fruity Italian olive oil produces the best flavor.
Can I add protein?
Certo! Grilled shrimp, chicken, or sautéed mushrooms pair wonderfully, though the classic version is beautifully simple on its own.
Burned garlic becomes bitter. Cook it gently until it's lightly golden so it perfumes the oil without overpowering the pasta.

📞 Chiacchierata (chat)
One of the first lessons my mamma taught me in the kitchen was that simple doesn't mean ordinary. In fact, some of Italy's most treasured recipes have only a handful of ingredients. Spaghetti Aglio e Olio is one of those dishes.
As Italians, we don't hide good ingredients—we celebrate them. That's why I always recommend buying the best spaghetti you can find. Look for pasta made with nothing more than semolina and water, and if you can find bronze-cut pasta, even better. Those tiny rough edges grab onto every drop of that glorious garlic-infused olive oil.
The magic isn't in adding more ingredients—it's in treating the ones you have with respect. Cook the garlic slowly, never rush it. Save that precious pasta water (it's liquid gold!), and toss everything together until the sauce becomes silky and glossy. With a little patience, you can turn simple pantry staples into something special. It will taste as if; it came from a cozy trattoria. Picture an Italian side street, warm and welcoming.
Whenever I make this recipe, the smell of garlic sizzling softly takes me back. It reminds me of family meals, where nobody cared if dinner was fancy. We cared that it was made with love, shared around the table, and enjoyed with plenty of conversation. That's the Italian way.
So pour yourself a glass of vino. Call everyone to the table. And remember what we always say: la semplicità è la vera eleganza—simplicity is true elegance.
Buon appetito, amici! ❤️

Equipment Needed
Ingredients
- Kosher salt

- ¾ cup reserved pasta water
- Parmesan cheese grated if desired
Instructions
- In a pot of salted boiling water, cook spaghetti until just shy of al dente (about 1 minute less than the package directs). Reserve ¾ cup pasta cooking water. (You may not need all of the pasta water!)
- Meanwhile, in a large skillet, combine 6 tablespoons oil and garlic. Add pinch of red pepper flakes, if using. Cook over medium heat until garlic is very lightly golden, about 5 minutes. (Adjust heat as necessary to keep it gently sizzling.)
- Transfer the pasta to the skillet along with ½ cup of the reserved pasta water.
- Increase the heat to high, and cook, stirring and tossing rapidly, until a creamy, emulsified sauce forms and coats the noodles.
- Remove from the heat, add the remaining 2 tablespoons of olive oil, and stir well to combine.
- Sprinkle with parsley and Parmesan cheese, and a few more peperoncini, if using, and serve right away.

Gently cooking the garlic and peperoncino in the oil infuses this incredibly easy sauce with flavor.
