Originally, Alfredo was made with just pasta, butter, and parmesan. It’s evolved over the years, and the Alfredo sauces that you find at the grocery store, as well as at many restaurants are more of a bechamel-based sauce. This recipe is not the original Alfredo, but rather part of the evolution of Alfredo sauces. It is meant to be creamy, comforting, a little indulgent, and super easy to make.

Frequently Asked Questions

Can I make Alfredo sauce ahead of time and reheat it later?

Certainly! Store the sauce in an airtight container in the refrigerator for up to 4 days. When ready to reheat, warm the sauce gently on the stovetop, stirring occasionally until it’s heated through.

Can I use margarine or plant-based substitutes?

To make this Alfredo sauce, it’s important to use real butter and half and half. Substitutes such as margarine or a plant-based milk will not yield the same results. The richness and creaminess of real butter and half and half are what make this sauce so delicious. Don’t skimp on the quality of your ingredients!

Can I use milk instead of half and half?

While you can use milk as a substitute for half and half, the resulting sauce will not be as rich and creamy. You can always substitute with whole milk, but the sauce will not have the same texture and flavor as when made with half and half.

Can I use a different type of cheese instead of parmesan?

Parmesan cheese is the traditional cheese used in Alfredo sauce, but you can experiment with other hard, salty cheeses if you prefer. Asiago or pecorino romano can be good substitutes for parmesan, but be aware that the flavor and texture of the sauce may be slightly different.

Troubleshooting

  • Sauce is too thin: You can add a little more grated parmesan cheese or simply let it simmer for a few more minutes to reduce and thicken. Alternatively, you can make a slurry by mixing a small amount of cornstarch with cold water and whisk it into the sauce while it’s simmering to help it thicken.
  • Sauce is too thick: Add chicken broth, a little at the time, to thin out the sauce.
