How to Make the Recipe

Step 1

Cook fettuccine in salted boiling water until al dente. Reserve 1 cup of pasta water, then drain and set aside.

Step 2

In a large saucepan over medium heat, melt the butter. Add minced garlic and sauté for about 1 minute until fragrant.

Step 3

Whisk in the flour and cook for 1–2 minutes to form a roux, stirring constantly to avoid browning.

Step 4

Slowly pour in the heavy cream and milk, whisking until smooth and beginning to thicken.

Step 5

Stir in Parmesan and Romano cheeses, whisking until fully melted and the sauce is velvety.

Step 6

Season with salt and black pepper to taste. Adjust consistency with a bit of reserved pasta water if needed.

Step 7

Toss the cooked fettuccine in the sauce until well coated. Garnish with fresh parsley before serving.

Tips for Making the Recipe

Use room temperature cheese to help it melt evenly into the sauce.
Don’t overcook the garlic—it should be fragrant but not browned.
Whisk constantly while adding the milk and cream to prevent lumps.
Add cheese off the heat to avoid separating or clumping.
Save some pasta water to adjust the sauce’s consistency if it thickens too much.

How to Serve

Serve Alfredo sauce immediately tossed with hot pasta. Plate it with extra grated Parmesan on top and a sprinkle of chopped parsley. It pairs wonderfully with a side salad, garlic bread, or sautéed vegetables. For a complete meal, top with grilled chicken, shrimp, or roasted vegetables.

Make Ahead and Storage

Storing Leftovers

Store leftover Alfredo pasta or sauce in an airtight container in the refrigerator for up to 3 days.

Freezing

Freezing is not recommended as the sauce may separate when thawed. However, if you must freeze, store in a freezer-safe container and reheat gently.

Reheating

Reheat on the stove over low heat, adding a splash of milk or cream to bring back its creamy consistency. Stir frequently and avoid overheating.

FAQs

Add a bit of pasta water, milk, or cream to thin it out.
