Main Ingredients

8 ounces spaghetti
10 tablespoons unsalted butter
3 cloves garlic, minced
1 teaspoon crushed red pepper flakes (optional)
½ cup freshly grated Parmesan cheese
Kosher salt, to taste
Freshly ground black pepper, to taste
2 tablespoons chopped fresh parsley leaves

These ingredients work together to create a silky, flavorful pasta dish with classic Italian-inspired comfort.

Let’s Get Started

Start by bringing a large pot of salted water to a boil.

Add the spaghetti and cook according to package directions until al dente.

Before draining, reserve about 1 cup of pasta water.

Drain the spaghetti and set aside.

In a large skillet or sauté pan, melt the butter over medium heat.

Once melted, add the minced garlic.

Cook for about 1–2 minutes, stirring constantly to prevent burning.

If using crushed red pepper flakes, stir them in now.

Cook for another 30 seconds.

Add the cooked spaghetti to the skillet.

Toss gently to coat the pasta in the garlic butter.

Gradually sprinkle in the Parmesan cheese while tossing.

Add small amounts of reserved pasta water as needed to help create a smooth, glossy sauce.

Season with kosher salt and freshly ground black pepper.

Continue tossing until the cheese melts fully and coats the spaghetti evenly.

Remove from heat.

Sprinkle with fresh parsley.

Serve immediately with extra Parmesan if desired.

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to 3 days.

Freezing is not recommended, as the butter-based sauce may separate.
