Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

16 oz fettuccine pasta
6 tablespoons salted butter
1 tablespoon minced garlic
1 teaspoon garlic powder
2 cups heavy cream
1 ½ cups freshly grated Parmesan cheese
½ teaspoon salt
½ teaspoon black pepper
2 tablespoons chopped fresh parsley (optional)

Directions

Start by bringing a large pot of salted water to a boil. Cook the fettuccine according to the package instructions until al dente. Reserve about half a cup of pasta water, then drain the pasta and set it aside.

In a large skillet over medium heat, melt the butter completely. Add the minced garlic and sauté for about one minute until fragrant, being careful not to burn it. Stir in the garlic powder for an extra layer of flavor.

Pour in the heavy cream and gently stir. Allow the mixture to simmer for about 3 to 5 minutes, stirring occasionally. This helps the sauce begin to thicken slightly.

Gradually add the grated Parmesan cheese while continuously stirring. The cheese should melt smoothly into the sauce, creating a creamy consistency. If the sauce becomes too thick, add a small amount of the reserved pasta water to loosen it.

Season the sauce with salt and black pepper, adjusting to taste. Once the sauce is smooth and creamy, add the cooked fettuccine directly into the skillet. Toss the pasta until it is fully coated in the Alfredo sauce.

Remove from heat and sprinkle with chopped parsley if desired. Serve immediately while hot and creamy.

Variations

You can easily customize this Alfredo recipe to suit your preferences. Add grilled chicken slices for a protein-packed dish or sautéed shrimp for a seafood twist. Steamed broccoli or spinach can bring a fresh and nutritious element to the dish. For a slightly lighter version, you can substitute part of the heavy cream with milk, though the sauce may be less rich. If you enjoy a bit of spice, add a pinch of red pepper flakes. You can also experiment with different cheeses like Romano for a sharper flavor.

Storage/Reheating

Store any leftover Alfredo pasta in an airtight container in the refrigerator for up to 3 days. When reheating, place the pasta in a pan over low heat and add a splash of milk or cream to help restore its creamy texture. Stir gently until heated through. Avoid overheating, as the sauce can separate. Microwaving is possible, but it’s best done in short intervals with stirring in between.

FAQs

Can I make Alfredo sauce without heavy cream?

Yes, but the texture and richness will change. You can use milk with a bit of flour or cream cheese for thickness.

What type of pasta works best?

Fettuccine is traditional, but you can use penne, linguine, or even spaghetti.

Why is my sauce too thick?

This usually happens if too much cheese is added or it cooks too long. Add a bit of pasta water or milk to thin it.

Can I use pre-grated Parmesan cheese?

Freshly grated Parmesan melts better and gives a smoother sauce, but pre-grated can work in a pinch.

How do I prevent the sauce from separating?

Cook on low to medium heat and avoid boiling after adding the cheese.

Can I freeze Alfredo sauce?

It’s not recommended because the cream-based sauce may separate when thawed.

Is this recipe suitable for vegetarians?

Yes, as long as the Parmesan cheese used is made without animal rennet.

Can I add protein to this dish?

Absolutely. Chicken, shrimp, or even grilled fish pair well with Alfredo sauce.

How do I make it healthier?

Use less butter, substitute part of the cream with milk, and add vegetables like broccoli or spinach.

What can I serve with Alfredo pasta?

Garlic bread, a fresh green salad, or roasted vegetables make great side dishes.
