I’m telling you right now. Once you try this creamy homemade alfredo sauce, you’ll never enjoy the jarred version the same way again.

What is Alfredo Sauce?

Alfredo sauce is a white sauce made with butter, cream and grated cheese.

You’re not alone if you wonder where alfredo sauce got its name. At first, I thought it was named for a person, but it actually got its name from a restaurant! A famous restaurant in Rome called Alfredo alla Scrofa perfected its earliest alfredo sauces in the 1920s, made from butter and cheese and mixed directly with hot fettuccine pasta.

American chefs played around with this recipe, adding cream, less expensive cheeses, and spices to create the version of Fettucine Alfredo we know and love. These days you can find some version of pasta with Alfredo sauce at just about every restaurant featuring Italian-American cuisine.

How do I roast garlic?

This post details the simple process of roasting your own garlic. It’s so easy, and you can store it in the refrigerator or freezer to use in other recipes too!

You start with a whole head of garlic drizzled with olive oil. Wrap it in foil and bake until the cloves become buttery soft and your kitchen smells like garlic heaven.

Ingredients for Roasted Garlic Alfredo Sauce

What ingredients do I need to make Roasted Garlic Alfredo Sauce?

You will need a few simple, fresh ingredients to make this creamy alfredo sauce:

For the roasted garlic:

  • 1 head of garlic
  • olive oil for drizzling

For the cream sauce:

  • unsalted butter

  • Parmesan cheese – freshly grated, NOT from a shaker can!
  • flour
  • salt
  • pepper

To make garlic fettucine alfredo, you’ll also need cooked fettucine noodles for serving.

Process steps for Roasted Garlic Alfredo Sauce.

How to make homemade Roasted Garlic Alfredo Sauce

Remove the cloves of garlic from the garlic head by gently squeezing them out the bottom. Place the garlic cloves into a small bowl and mash them with a fork. Yes, it is a lot of garlic, but I firmly believe you can never have enough garlic!

In a small saucepan, melt butter over low to medium heat. Add the fresh cream and roasted garlic cloves to the melted butter. Heat to very warm, but DO NOT boil.

Mix in the Parmesan cheese, salt, and pepper. Whisking it constantly until the cheese is fully melted and the sauce looks smooth.

To thicken the sauce, combine 2 teaspoons of flour with 1 tablespoon of heavy cream in a small bowl. Add the flour mixture into the saucepan, then stir and heat until the sauce thickens. Pour the sauce over fettuccine noodles or another favorite cooked pasta and enjoy!

How to store leftover homemade Alfredo Sauce

This flavorful sauce is so nice to have around to add to meat or pasta for a quick meal. Luckily, it’s easy to store any leftover sauce!

Once your roasted garlic alfredo sauce has cooled, transfer it to an airtight container and store it in the refrigerator. I store mine in a mason jar with a tightly sealed lid. It will last for 3-4 days in the fridge.

The garlicky flavor gets even bolder after a day or two. This would be a great sauce to prep on the weekend and keep in the fridge for easy meals during the week.

When you’re ready to serve your leftover sauce, just reheat in the microwave or in a pot on the stove. The sauce will look thicker while it’s still cold, but should smooth out to the perfect consistency as it warms up. If the sauce is still thicker than you want, you can always whisk in a bit more heavy cream or milk until you reach the consistency you like.

Can you freeze Alfredo sauce?

You can freeze alfredo sauce too! Pour it into a freezer-safe container and freeze it for up to 4 months. To reheat it, let it thaw completely, then reheat it on the stovetop or microwave. Stir it well as it heats until it is creamy and warm throughout.

This classic alfredo sauce can be served with so many things! Of course, you can make Fettuccine Alfredo with fresh or dried fettuccine noodles. You can use other wide, flat noodles such as linguine or tagliatelle to sop up some of this hearty, creamy sauce.

Garlic Alfredo Sauce is also a tasty dipping sauce for bread. Try this recipe for Italian Herb and Cheese Bread or Grandma’s Easy Homemade Italian Bread. Garlic bread and breadsticks would taste amazing when dipped into this parmesan cream sauce! Like I said, you can never have too much garlic.

Try pouring Roasted Garlic Alfredo Sauce over the meat dish of your choice for protein rich meal. Make classic Chicken Alfredo by pouring the sauce over some grilled chicken or toss the sauce with cooked shrimp. Add a side of broccoli for a balanced meal the whole family will love.
