Olive Garden’s Alfredo Sauce

Why You’ll Love This Recipe

I love how fast this Alfredo sauce comes together. In about 20 minutes, I can have a silky, flavorful sauce ready to coat perfectly cooked pasta.

I also appreciate how simple the ingredients are. With butter, cream, milk, and cheese, I can create something that tastes luxurious without needing anything complicated.

Another reason I keep this recipe on hand is how versatile it is. I can serve it as-is or add chicken, shrimp, or vegetables to turn it into a complete meal.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

6 tablespoons salted butter, high quality
1 tablespoon garlic, minced
2 tablespoons all-purpose flour
1 1/2 cups heavy cream
1 1/2 cups whole milk or 1% or 2%
1/2 cup Parmesan cheese, grated and at room temperature
1/2 cup Romano cheese, grated and at room temperature
Salt, to taste
Black pepper, to taste
1 lb fettuccine
Fresh parsley, for garnish

Directions

I start by boiling the fettuccine according to the package instructions so it is ready at the same time as the sauce.

In a large saucepan, I melt the butter over medium heat. I add the minced garlic and cook it for about a minute until it becomes fragrant.

Next, I whisk in the flour and cook it briefly while stirring continuously. This helps create a smooth base for the sauce.

I slowly pour in the heavy cream while whisking constantly, then gradually add the milk. I keep stirring to make sure the mixture stays smooth and lump-free.

Once the sauce begins to gently bubble, I reduce the heat and let it simmer until it thickens slightly. I stir occasionally to keep the texture even.

I lower the heat and slowly mix in the Parmesan and Romano cheese, letting them melt into the sauce. Then I season with salt and black pepper to taste.

After draining the pasta, I add it directly into the sauce and toss everything together until the pasta is well coated and the sauce thickens further. I finish with fresh parsley and serve it right away.

Servings and timing

I usually expect this recipe to serve about 4 to 6 people, depending on portion size. For timing, I plan around 10 minutes of prep time and about 15 to 20 minutes of cooking, making the total time roughly 25 to 30 minutes.

Variations

I sometimes add grilled chicken or shrimp when I want to turn this into a more filling meal. Both options pair beautifully with the creamy sauce.

If I want a slightly lighter version, I use lower-fat milk, though I keep in mind the sauce will be less rich. For a more intense cheese flavor, I add a bit more Parmesan or even a touch of Asiago.

I also like adding steamed broccoli, mushrooms, or spinach for extra texture and balance. It gives the dish a bit of freshness alongside the richness.

storage/reheating

I store any leftovers in an airtight container in the refrigerator for up to 3 days. I make sure to let it cool before storing so the texture stays as smooth as possible.

When reheating, I warm it gently on the stovetop or in the microwave. I usually add a splash of milk to help loosen the sauce and bring back its creamy consistency.

I avoid overheating because it can cause the sauce to separate. I also do not freeze this sauce, since cream-based sauces tend to lose their texture after thawing.

FAQs

Can I use only one type of cheese?

Yes, I can use only Parmesan if that is what I have. However, I find that combining Parmesan and Romano gives a deeper, more balanced flavor.

Why is my Alfredo sauce too thick?

If the sauce gets too thick, I add a little milk while stirring until it reaches the consistency I like.

Can I make this sauce ahead of time?

I can make it ahead, but I prefer serving it fresh for the best texture. If I do make it in advance, I reheat it gently with added milk.

What pasta works best with Alfredo sauce?

I like fettuccine the most because it holds the sauce well, but I can also use linguine, penne, or even spaghetti.

How do I prevent the sauce from becoming grainy?

I make sure to add the cheese slowly over low heat and stir continuously. Using room-temperature cheese also helps it melt smoothly.
