Ingredients You’ll Need

12 ounces spaghetti: The classic pasta choice that cooks perfectly al dente and holds on to the sauce.
Kosher salt: Enhances the overall flavor of the pasta; generous salting is key.
1/2 cup extra virgin olive oil: Offers a rich flavor that’s the backbone of this dish; opt for high-quality oil for a deeper taste.
8 garlic cloves, thinly sliced: Adds a sweet, nutty flavor when sautéed; be careful not to burn them.
1/2 teaspoon red pepper flakes (optional): For that little kick! Adjust to your heat preference, or leave them out entirely.
1/3 cup grated parmesan (optional): Adds a savory depth; feel free to increase the amount for more cheesy goodness or skip for a vegan option.
Chopped parsley (optional, for garnish): Provides freshness and a pop of color; also a subtle flavor enhancer.

How to Make Spaghetti Aglio e Olio

Cook the Pasta: Start by bringing a large pot of water to a rolling boil. Don’t forget to generously salt it with about 1 tablespoon of kosher salt. Add the spaghetti and cook it according to the package instructions, usually around 9 minutes, until just before al dente. Reserve 1 ½ cups of the pasta cooking water before draining the spaghetti.
Warm the Olive Oil: Meanwhile, heat the 1/2 cup extra virgin olive oil in a large pan over medium heat. Once it’s warm, add the thinly sliced garlic. Stir gently, cooking until the garlic turns a light golden brown — this should take about 2 to 3 minutes. Keep an eye on it, lowering the heat if necessary to prevent burning.
Add Red Pepper Flakes: As the garlic begins to brown, toss in the 1/2 teaspoon of red pepper flakes, if you’re using them. Stir for about 30 seconds to let the flavors meld. If the pasta isn’t ready yet, take the pan off the heat.
Incorporate Pasta Water: Once your pasta is cooked and drained, return the pan to medium heat, whisk in the reserved pasta water, and bring it to a gentle simmer. Allow it to simmer until the liquid reduces by about one-third.
Combine Pasta and Sauce: Add the drained spaghetti to the pan, tossing it in the fragrant garlic-oil mixture. Stir until every strand is well-coated. Turn off the heat, and if desired, add the grated parmesan and chopped parsley, tossing again to combine.
Rest & Serve: Let the pasta rest for a couple of minutes to absorb the sauce flavors before serving. Sprinkle on additional parmesan and red pepper flakes to taste, if you like.

Storing & Reheating

To enjoy leftovers, store your Spaghetti Aglio e Olio in an airtight container in the refrigerator for up to 3 days. If you want to keep it longer, you can freeze it for up to 3 months. When ready to enjoy again, thaw in the fridge overnight and reheat gently in a pan over medium heat. Add a splash of olive oil or a bit of reserved pasta water to help refresh the flavors. While the texture may soften slightly upon reheating, a simple addition of fresh garlic or herbs can brighten it right back up.

Chef’s Helpful Tips

Be cautious with garlic: Don’t let it turn dark brown, which indicates burning. Golden is your goal for a deliciously sweet flavor.
Pasta water magic: Always reserve that starchy water; it’s a chef’s secret to a silky sauce.
Timing is key: If your pasta is done cooking first, you can toss it briefly in the olive oil mixture off the heat, keeping it just warm until serving.
Experiment with flavors: Toss in some sautéed spinach or cherry tomatoes for a pop of color and extra nutrients.
Adjust salt: Since the pasta water is salted, taste before adding more salt to the final dish.

Spaghetti Aglio e Olio not only serves as a comforting staple but also invites creativity. There’s something beautiful in its simplicity, making it a canvas for your favorite additions. Whether you want to heat up the spice or brighten it with fresh herbs, this recipe provides the perfect base.

Can I use a different type of pasta?

Absolutely! While spaghetti is traditional, you can experiment with any pasta shape you enjoy. Just remember to adjust the cooking time according to the package directions.

What if I don’t have parmesan cheese?

No worries! You can skip the cheese entirely, or use nutritional yeast for a cheesy flavor in vegan variations. This dish is delicious even without any cheese.

Is Spaghetti Aglio e Olio spicy?

Yes! Grilled shrimp, chicken, or even chickpeas pair wonderfully with Spaghetti Aglio e Olio. Just sauté them separately and add them in when mixing the pasta with the sauce.
