HOMEMADE ALFREDO SAUCE RECIPE-

What is Alfredo Sauce? Alfredo sauce is a classic Italian sauce that is sometimes called white sauce. It uses butter, parmesan cheese, and heavy whipping cream and is seasoned to taste.

The rich and creamy sauce goes great with pasta like Fettucine and protein like our pan-seared chicken or even air-fryer shrimp.

This homemade Alfredo version beats Olive Garden’s and the store-bought Ragu sauce any day and is so easy and quick to make!

INGREDIENTS-

Alfredo sauce is so simple and uses just a few ingredients, ones you most likely already in your fridge – winner.

  • Heavy Cream– Heavy whipping cream for a richer flavor.
  • Milk– Helps balance the richness and thickness of the sauce.
  • Butter– Unsalted butter adds a depth of flavor to the sauce.
  • Garlic– Enhances the bland taste; don’t skip the fresh garlic. You can use salted butter, but then use less salt for seasoning.
  • Flour– Acts as a thickening agent.
  • Parmesan cheese– You can use store-bought grated cheese or grate fresh cheese with excellent results.
  • Salt and pepper– Season the sauce to taste.

Pro Tip: The consistency of this Alfredo sauce is thick. Use 2 teaspoons of flour instead of 1 tablespoon for a thinner sauce!

HOW TO MAKE homemade ALFREDO SAUCE-

Making homemade Alfredo sauce from scratch is quick and easy; let’s start.

  2. In a separate bowl, whisk together the heavy whipping cream and flour.
  3. Stir in the milk and heavy whipping cream/flour into the butter and garlic.
  4. Add the parmesan cheese and season with salt and pepper to taste.
  5. Cook the sauce, stirring frequently until the sauce thickens.

SERVE WITH-

Whenever you think of Alfredo sauce, the first thing that comes to mind is pasta and you are right. However, don’t limit the creamy sauce just to the pasta, enjoy Alfredo in so many variations:

storage & reheating:

We often like to make two to three portions of the Alfredo Sauce and use it in different variations and here are ways to store the white sauce once it’s made.

  • Fridge- The sauce will stay fresh in a jar sealed for 4-5 days in the refrigerator.
  • Reheat– Reheat over low heat until hot. You may need to add more milk if the sauce is too thick.
  • Freezing– We don’t recommend freezing the Alfredo Sauce.

How to make a healthy Alfredo sauce?

For a healthier option, leave out the heavy whipping cream and substitute for milk instead.

What can I use instead of heavy whipping cream?

You can substitute the cream with half and half for a lighter sauce.

How to keep sauce from burning?

You want to make sure to keep the sauce cooking over low/medium heat. If you cook it over high heat, the sauce will separate and you can scorch the bottom.

Why did my sauce separate?

The heat was too high and it scorched the milk causing it to separate. You want to keep it at med/low heat.
