Ingredients

12 ounces spaghetti, linguine, or your favorite pasta
6 tablespoons unsalted butter
5 garlic cloves, finely minced
1/2 cup finely grated Parmesan cheese
1/2 cup reserved pasta water, plus more as needed
1 tablespoon fresh lemon juice
1/4 teaspoon red pepper flakes, optional
2 tablespoons chopped fresh parsley
Salt and black pepper, to taste

Step-by-Step Instructions for Garlic Butter Pasta

First, bring a large pot of salted water to a boil. Cook the pasta according to the package directions until al dente.
Before draining, reserve at least 1/2 cup of the pasta water. This starchy water helps loosen and emulsify the sauce.
Meanwhile, melt the butter in a large skillet over medium-low heat. Add the garlic and cook for 1 to 2 minutes, stirring often.
Next, stir in the red pepper flakes, if using. Cook briefly, but do not let the garlic turn dark brown.
Add the drained pasta to the skillet. Toss well so the butter coats every strand.
Gradually add the reserved pasta water while tossing. Continue until the sauce looks smooth and lightly glossy.
Remove the skillet from the heat. Add the Parmesan, lemon juice, parsley, salt, and black pepper.
Finally, toss again and serve immediately with extra Parmesan and parsley, if desired.

Pro Tips for the Best Garlic Butter Pasta

Salt the pasta water generously because it seasons the noodles from the inside.
Cook the garlic over medium-low heat so it becomes fragrant without burning.
Reserve more pasta water than you think you need. The sauce can thicken as it sits.
Use freshly grated Parmesan because it melts more smoothly than pre-shredded cheese.
For extra protein, add cooked chicken, shrimp, or white beans.
For more vegetables, toss in spinach, peas, broccoli, or sautéed mushrooms.

Storage Instructions

Allow leftover garlic butter pasta to cool before transferring it to an airtight container. Refrigerate it for up to 3 days. Reheat gently in a skillet with a splash of water or broth, because this helps loosen the sauce and prevents the pasta from drying out.

Garlic Butter Pasta Recipe FAQ

Can I use a different type of pasta?

Yes. Spaghetti, linguine, fettuccine, penne, and shells all work well. However, long noodles hold the buttery sauce especially nicely.

Can I make garlic butter pasta without Parmesan?

Absolutely. You can leave out the Parmesan or replace it with Pecorino Romano. Nutritional yeast also adds a savory flavor for a dairy-free variation, although the texture will be slightly different.

How can I make this recipe more filling?

Add cooked chicken, shrimp, salmon, white beans, or crispy bacon. Additionally, vegetables such as spinach, peas, and broccoli make the meal more balanced.

Why is my sauce oily?

The sauce may need more pasta water. Add it one tablespoon at a time while tossing vigorously. This helps the butter and water combine into a smoother sauce.
