Olive Garden Alfredo Sauce:

-Olive Garden’s Alfredo Sauce recipe is made with Parmesan and Romano Cheeses, however you can also incorporate Mozzarella, Gruyere, Gouda, or Asiago. You can also just use Parmesan.

-You can use half and half instead of half heavy cream/half milk.

If you only have evaporated milk, just use half the amount of milk and replace the other half with water. You won’t compromise flavor or consistency by doing this in creamy sauces like this one.

-You can even experiment with different pastas. I like fettuccine because the noodles soak up that thick sauce well. Bow tie pasta does great with Alfredo sauce too, as I’ve proven in this Skillet Chicken Alfredo Recipe.

How to Make Alfredo Sauce:

Melt the butter. Add the garlic and cook for 1 minute.

Add half and half. Gradually whisk in the cheese.

Add cooked Fettuccine. Sauce will continue to thicken upon standing.

Tips for Extra-Creamy Alfredo Sauce

  • Use blocks of (high-quality) cheese and shred it yourself for extra creamy, non-grainy results.
  • Let the cheese come down to room temperature before adding it to the sauce.
  • Sprinkle in the cheese gradually, the sauce should be warm but not too hot.
  • High-quality butter is important. You can also make your own butter.

Note: Bagged shredded cheese has cellulose added to it to prevent the cheese from sticking together in the bag. Cellulose repels moisture, which makes it melt poorly in comparison to shredding the cheese yourself.

⭐Pro Tip:

  • Alfredo sauce continues to thicken upon standing, and thickens even more when it’s added to pasta.
  • Refrain from adding additional cheese to thicken it up, the consistency is generally on the thinner side.

Making Alfredo Sauce Ahead of Time

  • Alfredo sauce is a convenient make-ahead and freezable sauce. Unlike some other cheese sauces, the flour in this recipe helps it to maintain it’s consistency when cooled and reheated.
  • It can be stored in the refrigerator for up to 3 days.
  • It can also be frozen and is best if used within 1-2 months.

How to Reheat Fettuccine Alfredo

  • For best results, reheat cold fettuccine already in a double boiler with the lid on. The consistency, texture, and flavor is much better than microwaving. (Here’s how to make your own double boiler.)
  • Frozen Alfredo sauce should be thawed overnight in the fridge before reheating.
  • If the sauce is too thick when reheated, add a splash of milk or chicken broth to thin it out.

Recipe Notes

Note: You may be tempted to add more cheese to thicken to sauce, but it continues to thicken upon standing and even when added to the pasta.

Alfredo sauce is generally thinner than you may think and thickening it further may make it too rich.

How to Reheat Alfredo Sauce

  • Alfredo sauce will thicken up and harden as it cools, but can be easily microwaved or slowly reheated on the stove top. You'll see it begin to take on more of it's original form as it reheats. 
  • Frozen Alfredo sauce should be thawed overnight in the fridge before heating.
  • If the sauce is too thick when reheated, add a splash of milk or chicken broth to thin it out.
