3 Ingredient Alfredo Sauce

You’re never going to want to buy alfredo again thanks to this 3 ingredient alfredo sauce recipe! Made with minimal effort and ingredients, this sauce turns out amazingly over any pasta.

If you've never tried alfredo sauce, this is a pasta sauce made with parmesan cheese, butter, salt, and pepper. Traditionally it doesn't contain cream, but a lot of homemade recipes often have it starting with a roux or containing additional spices and herbs as ingredients. That said, alfredo isn't an authentic Italian dish and we aren't going to authentic here, we are going for delicious.

I absolutely love creamy alfredo sauce recipes and it’s not hard to guess why. This recipe is perfect for a quick meal and it doesn’t require much effort to make either.

The sauce comes together in mere minutes, making it an ideal quick solution for transforming plain pasta into a decadent meal that feels both sophisticated and comforting.

How to Make Alfredo Sauce

How to Thicken The Sauce

There are several different ways that you can thicken your alfredo sauce but for this recipe, you may want to cook just a little longer while stirring or stir in more freshly grated parmesan cheese.

Sometimes the sauce just needs a little longer to warm up before it comes together. If that doesn’t work then you can always stir in a cornstarch slurry.

Expert Tips

• Don't Skip the Nutmeg: I know it can seem a little bit unusual for a savory dish, but it adds a special flavor that really complements all the rich creaminess going on.
• Save Pasta Water: You may need to thin the sauce a bit with pasta watet or regular water. The pasta water is a bit starchy, which is great for sauces.
• Cook Over Low Heat: Keep the heat low to prevent the sauce from separating or the cream from scorching. Patience is key for a silky texture.
• Serve Immediately: Alfredo sauce thickens as it cools, so serve it right after it’s made for the best texture and taste.

Serving & Storage Suggestions

If you want to make chicken alfredo, just pan-fry some chicken breasts in the skillet before making the alfredo sauce. Here's how I like to do it: 

• Heat 1 tablespoon of olive oil over medium heat. 
• Slice 2 chicken breasts in half lengthwise {so they are thinner}. 
• Salt and pepper on both sides. 
• Place in skillet and cook for about 5 minutes a side until golden brown and the internal temperature registers 160ºF. 
• Rest, covered with foil, while you make the alfredo sauce. 

Storage Tips: You can keep your sauce stored in an airtight container in the fridge for up to 3-5 days.

For longer storage, it's best to freeze it. To do this allow the sauce to cool completely before storing it in a freezer-safe airtight container and freeze for up to 3 months.

Reheating: When reheating the sauce, do so over low heat in a saucepan. If re-heating pasta with this sauce on it, microwave until the chill has just been taken off, add a splash of cream, stir, and microwave until warmed through.

Alfredo Sauce Substitutions

This sauce is pretty decadent, so you could sub out the cream for half-and-half to lighten things up a bit.

Don't make this with the parmesan from the green can! I say this only because it really doesn't melt well and usually turns into a clump in the pot and that will just ruin your whole day. Clumps of cheese in pots are total downers.

You don't have to buy totally fancy Parmesan, but if you can buy some and grate it yourself it will melt into the sauce beautifully.
