What Is Alfredo Sauce?
Keep in mind this is an American-style Alfredo sauce and not a traditional one. Authentic Italian Alfredo (from Rome) doesn’t have any cream – just butter, Parmesan, pasta, and a little starchy pasta water to help form the sauce.
This Americanized version has butter, garlic, cheese, and cream. The cream makes it easy to make a thick and smooth sauce. I add a few other ingredients to give it a boost of flavor, too! This is the kind of sauce I grew up eating – it’s super comforting!
Why This Recipe Works
- This recipe is really fast! You can have a delicious, creamy Alfredo sauce in about 20 minutes.
- You can make fettuccine Alfredo or toss it with your favorite pasta shape.

- Sliced butter – add 1/4 teaspoon of salt to the sauce if you use unsalted butter.
- Heavy cream – I like cream because it’s rich and gives the sauce the best consistency. I don’t recommend using milk, but half and half will work. The sauce may not be as rich and thick.
- Garlic – We used both minced garlic cloves and garlic powder.
- Italian seasoning – You can also use dried oregano if that’s what you have on hand.
- Salt and Ground black pepper – White pepper also works! The flavor is milder, and you won’t see the flecks in the sauce.
- Grated Parmesan cheese – Parm is traditional, but you can also use Romano cheese or Asiago cheese. Also, use freshly grated cheese, so your sauce isn’t grainy.
How to Make Alfredo Sauce from Scratch
Heat the butter and cream in a skillet over medium-low heat. Whisk until the butter is melted.
Add the garlic, garlic powder, Italian seasoning, salt, and pepper and whisk them into the cream mixture.
Bring the sauce to a low simmer (not boiling) and cook the Alfredo, constantly whisking, for three to four minutes or until it thickens.
Stir in the cheese and whisk until it’s melted and the sauce is thick and creamy.
Use It to Make These Amazing Dinners
Don’t get me wrong, tossing this creamy Alfredo sauce with pasta is super delicious! But, you can add other ingredients to make it a new meal every time you make it. Here are some ideas:
- Chicken Alfredo: Cook some chicken breasts and slice or dice them. Stir them into the sauce at the end before you add the pasta. You can also use shredded rotisserie chicken to make it really easy.
- Shrimp Alfredo: Cook some shrimp in the skillet first before you make the sauce. Stir them in at the end or pile them on top of the pasta and sauce when you serve it.
- Broccoli Alfredo: Make a batch of my air fryer broccoli and add the cooked florets to the sauce before you serve it!
- Other Ideas: Use it to make a batch of Alfredo lasagna roll-ups! Or add it as a layer in homemade lasagna.
What is traditional Alfredo sauce made of?
Roman Alfredo is made with butter, finely grated Parmesan cheese, fresh homemade pasta, and a little starchy pasta water. When you combine the cheese, water, and butter it forms a sauce.

How long can Alfredo last in the fridge?
You can store the sauce in the refrigerator for up to three to four days. Warm it slowly in a saucepan over medium-low to medium heat. Whisk it while it’s heating.
What is the difference between white sauce and Alfredo?
A white sauce, or béchamel, is a sauce made with milk that is thickened with a roux made with flour and butter. Alfredo sauce has cheese and is not made with a roux.
