Ingredients You’ll Need

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

For the Pasta:

16 ounces fettuccine or linguine

For the Alfredo Sauce:

6 tablespoons salted butter
1 tablespoon minced garlic
1 teaspoon garlic powder
½ teaspoon salt
2 tablespoons all-purpose flour
1¼ cups heavy cream
1½ cups whole milk
1 cup freshly grated Parmesan cheese

For Serving:

Fresh parsley, finely chopped (optional)

Each ingredient plays an important role in building the sauce. Butter and cream provide richness, flour helps thicken the sauce, and Parmesan delivers that signature cheesy flavor. Using freshly grated cheese makes a noticeable difference in both texture and taste.

Let’s Get Started

Cook the Pasta
Bring a large pot of salted water to a boil and cook the fettuccine or linguine according to package instructions. Reserve about ½ cup of pasta water before draining.
Melt the Butter
In a large skillet or saucepan over medium heat, melt the butter until fully liquid.
Add Garlic
Stir in the minced garlic and cook for about 1 minute until fragrant. Be careful not to burn it.
Create the Base
Add garlic powder, salt, and flour. Whisk continuously for 1–2 minutes to form a smooth paste (roux).
Add Liquids
Slowly pour in the heavy cream and milk, whisking constantly to avoid lumps. Continue cooking for 3–5 minutes until the sauce begins to thicken.
Add Parmesan Cheese
Reduce heat to low and stir in the freshly grated Parmesan cheese. Mix until fully melted and smooth.
Combine with Pasta
Add the cooked pasta to the sauce and toss to coat. Use reserved pasta water as needed to adjust consistency.
Serve
Garnish with chopped parsley if desired and serve immediately.

Servings and Pairing

This recipe yields about 4–6 servings, making it perfect for family meals or leftovers.

Pairing Ideas:

Grilled chicken or shrimp for added protein
Steamed broccoli or spinach for a balanced plate
Garlic bread or breadsticks for a classic restaurant-style meal
A light salad with vinaigrette to cut through the richness

The creamy sauce pairs beautifully with both simple and more elaborate sides.

Variations

One of the best things about Alfredo sauce is how easy it is to customize. If you want a richer flavor, you can add extra Parmesan or even a small amount of cream cheese for added thickness.

For a lighter version, substitute part of the cream with more milk. While it won’t be as rich, it will still be delicious and slightly lower in calories.

You can also experiment with add-ins. Grilled chicken Alfredo is a classic, but shrimp, mushrooms, or even sun-dried tomatoes can bring a new twist to the dish. A pinch of red pepper flakes adds a subtle heat if you enjoy a bit of spice.

Storage Tips

Store leftover Alfredo pasta in an airtight container in the refrigerator for up to 3 days. When reheating, add a splash of milk or cream to help restore the sauce’s creamy consistency.

Reheat gently on the stovetop or in the microwave, stirring occasionally to prevent separation. Avoid overheating, as this can cause the sauce to become grainy.

Freezing is not recommended for Alfredo sauce, as the dairy can separate and affect the texture when thawed.

FAQs

Can I use pre-shredded Parmesan cheese?

Freshly grated Parmesan is recommended because it melts better and creates a smoother sauce.

Why is my Alfredo sauce too thick?

Add a little reserved pasta water or milk to thin it out to your desired consistency.

Can I make this sauce ahead of time?

Yes, but it’s best served fresh. If making ahead, reheat gently and stir well before serving.

Can I make it without flour?

Yes, you can skip the flour and let the cheese and cream naturally thicken the sauce, though it may be slightly thinner.
