Cheesy Garlic Parmesan Spaghetti

I threw this together on a Tuesday evening when the fridge was down to odds and ends, and now it is the recipe my friends actually text me about. The first time I made it, I was skeptical that something so simple could taste so restaurant worthy, but the way the garlic blooms in that butter changes everything. My husband walked in from work and immediately asked what smelled so incredible, which is basically the highest compliment a weekday dinner can get.

Last month my sister came over for a catch up dinner, and I made this spaghetti mostly because I was too tired to attempt anything fancy. She took three bites and literally stopped the conversation to ask for the recipe, which never happens because she is usually the one teaching me about food. Now she makes it for her family every Thursday, and her kids have started requesting it by name.

Ingredients

• 12 oz spaghetti: I have found that thin spaghetti works beautifully here because the sauce coats every single strand
• 2 tablespoons unsalted butter: Use real butter because the flavor foundation matters so much in a simple recipe
• 4 cloves garlic, minced: Freshly minced garlic makes a huge difference over jarred versions
• 1 cup heavy cream: This creates that luxurious restaurant style texture we all love
• 1 cup freshly grated Parmesan cheese: Buy a wedge and grate it yourself because pre grated cheese has anti caking agents that prevent smooth melting
• 1/2 cup shredded mozzarella cheese: This adds the most incredible stretch factor
• 1/4 teaspoon crushed red pepper flakes: Optional but such a nice way to cut through the richness
• 1/4 teaspoon black pepper: Freshly ground makes a noticeable difference here
• 1/4 teaspoon salt: Start with this and adjust because the Parmesan is already salty
• 2 tablespoons chopped fresh parsley: This adds a bright pop of color and freshness
• Extra grated Parmesan cheese: For serving because more cheese is always the right answer

Instructions

Start the pasta:

Bring a large pot of generously salted water to a rolling boil and cook the spaghetti until it is al dente, which usually means a minute or two less than the package says

Sauté the garlic:

While the pasta cooks, melt your butter in a large skillet over medium heat and add the minced garlic, cooking it just until it becomes fragrant and very pale gold

Build the sauce:

Pour in the heavy cream and let it come to a gentle bubble before stirring in both cheeses until they melt into a smooth, glossy sauce

Season it right:

Add your salt, black pepper, and red pepper flakes if you want that subtle warmth in the background

Bring it together:

Add the cooked spaghetti to the skillet and toss everything together, adding that reserved pasta water a splash at a time until the sauce coats each strand perfectly

Finish and serve:

Remove the skillet from heat immediately, sprinkle with fresh parsley and that extra Parmesan, and get it to the table while the cheese is still melty

Save

This recipe became my go to for comfort food because one bite takes me back to my grandmother is tiny kitchen where everything smelled like garlic and butter. She always said simple food prepared with love is better than complicated food made with hesitation, and this spaghetti proves her right every single time.

Making It Your Own

I love adding cooked chicken or shrimp when I want to make it feel more like a complete meal, and my friend adds sautéed spinach for extra color. The sauce base is so forgiving that you can really play with it once you make the basic version a few times.

Light It Up

Some nights I swap half and half for the heavy cream, and while it is not quite as luxurious, it still satisfies that creamy pasta craving without feeling quite so heavy. Gluten free pasta works beautifully here too, though I find it needs a little more pasta water to get the sauce consistency just right.

Serve It Like A Pro

A crisp green salad with a bright vinaigrette cuts through the richness perfectly, and a chilled glass of Pinot Grigio is exactly what this dish wants to be paired with. I learned to warm my serving bowls slightly because the pasta stays hot longer and the sauce stays perfectly silky.

• Grate your cheese fresh from a wedge instead of buying pre grated
• Reserve more pasta water than you think you need just in case
• Always finish with fresh parsley for that restaurant style touch

There is something so wonderful about a recipe that turns basic ingredients into something that feels like a special occasion, even on a random Tuesday.

Recipe FAQs

→ Can I make this dish ahead of time?

This dish is best served immediately while the sauce is creamy and smooth. If you need to prep ahead, cook the pasta and make the sauce separately, then combine just before serving. The sauce may thicken when refrigerated, so add a splash of pasta water or cream when reheating to restore consistency.

→ What can I use instead of heavy cream?

Half-and-half works well for a lighter version, though the sauce won't be quite as rich. Whole milk can also be used, but you may need to reduce it longer to achieve a thicker consistency. For a dairy-free option, try full-fat coconut milk, though it will alter the flavor profile slightly.

→ How do I prevent the cheese from clumping?

Always grate your own Parmesan cheese from a block instead of using pre-grated cheese, which contains anti-caking agents that prevent smooth melting. Add the cheese gradually while stirring constantly, and keep the heat at a gentle simmer rather than a rolling boil.

→ Can I use a different type of pasta?

Absolutely. Fettuccine, linguine, or angel hair pasta all work beautifully with this creamy sauce. For shorter pasta options, try penne, rigatoni, or fusilli. Just adjust the cooking time according to the package instructions and maintain the pasta-to-sauce ratio.

→ How spicy is this dish with red pepper flakes?

The quarter teaspoon of red pepper flakes adds a very mild warmth that enhances the flavors without overwhelming the dish. If you're sensitive to heat, start with an eighth teaspoon or omit entirely. For those who love spice, feel free to increase to half a teaspoon or more.

→ What sides pair well with this pasta?

A crisp green salad with vinaigrette cuts through the richness perfectly. Roasted vegetables like broccoli, asparagus, or Brussels sprouts add color and nutrition. Garlic bread or focaccia helps soak up any extra sauce. For wine lovers, a Pinot Grigio or Chardonnay complements the creamy flavors beautifully.
