Can I use milk instead of half and half?

You can substitute milk, but your sauce won't be as rich and creamy. If using milk, reduce the amount slightly and increase the butter and cheese to maintain richness. For an even richer sauce, heavy cream works beautifully too.

Why did my sauce turn out grainy?

Grainy sauce typically results from heat that's too high or pre-packaged cheese with anti-caking agents. Make sure to remove the pan from heat before adding cheese, and always use freshly grated Parmesan for best results.

Can I make this recipe with gluten-free pasta?

Absolutely! The sauce works wonderfully with gluten-free pasta. Just substitute the all-purpose flour with a gluten-free alternative like rice flour or a 1:1 gluten-free flour blend for the roux.

How can I make this healthier without sacrificing creaminess?

Try using whole milk instead of half and half, reducing the butter slightly, and increasing the amount of reserved pasta water to maintain creaminess. You can also add pureed cauliflower to the sauce for added creaminess with fewer calories.

Ingredients You’ll Need

Fettuccine: The traditional pasta choice for alfredo, with its wide, flat shape that holds the creamy sauce beautifully. The nooks and crannies capture all that delicious sauce.
Butter: Creates the rich base for our sauce. Using salted butter adds just the right amount of seasoning to complement the cheese.
All-purpose flour: Works with butter to form a roux, which thickens our sauce to that perfect, silky consistency.
Half and half: Provides the creamy texture without being as heavy as using straight cream. It’s the perfect balance of richness and lightness.
Garlic powder: Infuses the sauce with subtle garlic flavor without overpowering the dish or adding the texture of fresh garlic.
Salt: Enhances all the flavors in the dish. Remember to salt your pasta water too – it’s your only chance to season the pasta itself!
Parmesan cheese: The star ingredient that gives alfredo its distinctive flavor. Freshly grated works best as it melts more smoothly than pre-packaged options.
Pasta water: Save some! This starchy liquid is liquid gold for adjusting sauce consistency and helping the sauce adhere to the pasta.

How to Make Creamy Fettuccine Alfredo

Step 1: Cook the Pasta

Bring a large pot of water to a rolling boil and add salt. Cook the fettuccine according to package directions until al dente – tender but still firm to the bite. Before draining, remember to reserve about 1½ cups of the pasta water. This starchy liquid is your secret weapon for perfecting the sauce consistency later.

Step 2: Start the Sauce

While the pasta cooks, melt butter in a large skillet over low heat. Once completely melted, whisk in the flour to create a smooth paste (this is your roux). Cook for about 2 minutes over medium heat until it turns slightly golden. This cooking step is crucial as it removes the raw flour taste.

Step 3: Create the Cream Base

Gradually pour in the half and half while continuously whisking to prevent lumps. Add the garlic powder and salt, continuing to whisk as the mixture heats up. Patience is key here – whisking constantly ensures a silky-smooth sauce.

Step 4: Add the Cheese

As soon as the sauce begins to simmer, turn off the heat immediately (this prevents the dairy from separating). Add the Parmesan cheese and stir until completely melted and incorporated into a smooth, velvety sauce.

Step 5: Combine and Serve

Add the drained pasta directly to the sauce and toss thoroughly until every strand is coated. If the sauce seems too thick, gradually add some of the reserved pasta water until you reach your desired consistency. Garnish with extra freshly grated Parmesan and serve immediately.

Pro Tips for Making the Recipe

Grate Your Own Cheese: Pre-packaged grated Parmesan contains anti-caking agents that can make your sauce grainy. Freshly grated melts much better.
Don’t Boil the Sauce: Once you add the dairy, gentle heat is crucial. Boiling can cause separation and a grainy texture.
Use a Large Skillet: Having enough surface area makes tossing the pasta in the sauce much easier and ensures even coating.
Save More Pasta Water Than You Think: It’s better to have extra than not enough when adjusting your sauce consistency.
Serve Immediately: Alfredo sauce begins to thicken as it cools, so timing is everything for the perfect creamy texture.

How to Serve

Fettuccine Alfredo shines as both a main dish and an elegant side. Here are my favorite serving suggestions:

As a Main Course

Serve with a simple green salad dressed with a light vinaigrette to cut through the richness of the pasta. Garlic bread makes an excellent accompaniment for soaking up any extra sauce.

As a Side Dish

Pair with grilled chicken, steak, or seafood for a restaurant-worthy meal. The creamy pasta complements the char of grilled proteins beautifully.

Presentation

For an impressive presentation, twirl the pasta into a neat mound using tongs and a large serving spoon. Garnish with freshly cracked black pepper, a sprinkle of extra Parmesan, and a small sprig of fresh parsley.

Make Ahead and Storage

Storing Leftovers

Store in an airtight container in the refrigerator for up to 3 days. The sauce will thicken considerably when chilled.

Freezing

While possible, freezing isn’t ideal for cream-based sauces as they can separate when thawed. If you must freeze, do so in a freezer-safe container for up to 1 month.

Reheating

For best results, reheat leftovers in a skillet over medium-low heat. Add a splash of milk or cream to revive the sauce’s creamy texture, stirring gently until warmed through. Avoid microwave reheating if possible, as it can cause the sauce to separate.
