I love this recipe because it comes together in just 20 minutes, making it perfect for busy days. The ingredients are simple and easy to find, yet the flavor is incredibly rich and comforting. I also enjoy how versatile it is since I can customize it with extra vegetables, protein, or different herbs. The creamy Parmesan and garlic butter sauce makes every bite irresistible without requiring complicated cooking techniques.
Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
3 tablespoons unsalted butter
1/2 onion, finely chopped
4–5 cloves garlic, minced
1/2 teaspoon salt
1 teaspoon black pepper
1/2 teaspoon chili flakes
1 teaspoon oregano
1 teaspoon basil (optional)
1/2 cup freshly grated Parmesan cheese
1/4 cup reserved pasta water
8 ounces (225 g) dry pasta such as spaghetti, linguine, or another long pasta
Directions
I bring a large pot of salted water to a boil and cook the pasta according to the package instructions until al dente.
Before draining the pasta, I reserve 1/4 cup of the pasta cooking water. I then drain the pasta and set it aside.
In a large skillet over medium heat, I melt the butter.
I add the finely chopped onion and cook for about 3 to 4 minutes until it becomes soft and translucent.
I stir in the minced garlic and cook for about 30 seconds to 1 minute, just until fragrant.
I add the salt, black pepper, chili flakes, oregano, and basil. I stir everything together so the seasonings evenly coat the onion and garlic mixture.
I pour in the reserved pasta water and stir to combine, creating a light sauce.
I add the cooked pasta to the skillet and toss well so every strand is coated in the garlic butter mixture.
I sprinkle in the freshly grated Parmesan cheese and continue tossing until the cheese melts into the sauce.
I serve the pasta immediately with extra Parmesan cheese and herbs if desired.

Variations
I sometimes add grilled chicken, shrimp, or sliced sausage for extra protein.
I like mixing in spinach, peas, mushrooms, or broccoli for added vegetables.
I occasionally replace Parmesan with Pecorino Romano for a sharper flavor.
I can make the dish creamier by adding a splash of heavy cream.
I enjoy adding fresh parsley or fresh basil before serving for extra freshness.
storage/reheating
I store leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, I add a small splash of water or broth to help loosen the sauce. I warm the pasta gently in a skillet over medium-low heat or microwave it in short intervals, stirring occasionally until heated through.
FAQs
Can I use a different type of pasta?
Yes, I can use spaghetti, linguine, fettuccine, or even short pasta shapes such as penne or rotini.
Why should I save the pasta water?
I use pasta water because it helps create a silky sauce and allows the Parmesan cheese to blend smoothly with the butter.
Can I make this recipe spicy?
Yes, I simply increase the amount of chili flakes or add a pinch of cayenne pepper for extra heat.
Can I make this recipe ahead of time?
I can prepare it ahead, but I find that it tastes best when served fresh since the sauce is at its smoothest right after cooking.
What can I serve with garlic butter pasta?
I like serving it with a fresh salad, garlic bread, roasted vegetables, or grilled chicken for a complete meal.
