What Can You Substitute For Parmigiano Reggiano Cheese?

You could use Grana padano, Asiago, or Pecorino-Romano instead of Parmigiano Reggiano cheese. Or just plain Parmesan cheese. 

What Can I Use Instead Of Heavy Cream in Fettuccine Alfredo Sauce?

You could mix low-fat or non-fat versions of sour cream, plain yogurt, Greek yogurt or cream cheese with either chicken broth or milk, to replace the heavy cream

For a lighter sauce, you could just use milk or evaporated milk instead of heavy cream.

How Do You Thicken Fettuccine Alfredo Sauce?

The sauce should thicken as it cooks, but if it is not as thick as you want you can thicken it.

Bring the sauce to a good simmer.

Dilute 3 tablespoons of flour in a half cup of water.

Add mixture to the simmering sauce.

Keep stirring until the sauce has achieved the creaminess you want.

Is Heavy Cream Whipping Cream?

Yes, heavy cream and whipping cream are the same thing. You can also substitute milk for cream in Alfredo sauce if needed. Whole milk is the most creamy substitute for heavy cream. Whole milk contains 8 grams of fat per 1 cup compared to 96 grams of fat per 1 cup in heavy cream.

How Long Will Fettuccine Alfredo Sauce Keep?

Alfredo sauce will keep for up to one week in the refrigerator.

Can Alfredo Sauce Be Frozen?

Alfredo sauce can be frozen in an airtight container, or in a heavy-duty freezer bag. But you should not freeze fettuccine Alfredo together. It’s best to always make pasta separate.

Cream-based foods should be stirred as they are reheated to keep them from separating.
