Homemade Alfredo Sauce

Butter, heavy cream, and parmesan are the only ingredients you need to make an incredible homemade alfredo sauce. In just 10 minutes of cooking, you will have a sauce that’s creamier and more flavorful than any from a jar. This is the alfredo sauce our family makes over and over again. Richer than any sauce from a jar, this sauce comes together faster than the pasta boils. This sauce is even restaurant quality!

Why This One Works for Real Life

My family and I have been making this recipe for years and it’s become a special tradition because we all really love alfredo. I never buy store-bought alfredo because I discovered how surreal it is to make your own sauce. It takes just three ingredients and 15 minutes to make. I find it just as good as what you would find at a restaurant. Although we find it easier for our kids to eat it, we have made the switch to penne, it is really classic to eat fettuccine as well. It is also hard to go wrong with making your own alfredo sauce.

Ingredient Breakdown

Salted Butter (1/4 cup)

The foundation sauce is real, salted butter — NOT unsalted and NOT margarine. Salted butter does the seasoning for you. Just melt it on medium-low, and babysit it. I’ve burned butter before, and had to start over. It’s super quick.

Heavy Whipping Cream (1 cup)

With this recipe do *not* use substitutions like half-and-half, or even regular milk, and then be confused when the sauce breaks. People tend to use these ingredients to “lighten” the recipe, but it just doesn’t work! Heavy cream is the only option here, as it has at least 36% fat for optimal reducing and emulsifying. Using a lighter cream is not going to thicken the sauce in the same manner and could even curdle. This is *not* the place to cut costs.

Grated Parmesan Cheese (3/4 cup)

Don’t use powdered parmesan. Anti caking agents keep it from melting and you end up with a grainy chalky sauce that is impossible to salvage. This sauce is only going to be as good as the parmesan you use. For best results use freshly grated or store bought shredded parmesan. It’s worth the extra time to grate!

How to Make It

One thing to keep in mind before you start: This sauce is quick to make. Have your chicken cooked, pasta boiling, and table set before you start. When done, the sauce needs to go on the pasta right away.

1. Melt butter in a saucepan over medium-low heat. Don’t walk away — butter goes from melted to brown fast and you’ll smell it before you see it.
2. Add the heavy whipping cream. Whisk and heat until it comes to a gentle rolling boil. It’ll take a couple minutes — you’re looking for small, steady bubbles, not a hard boil.
3. Add the parmesan cheese. Whisk consistently for about 10 minutes until the cheese has fully melted and the sauce is smooth and slightly thickened. This is the step people rush and shouldn’t — stop whisking too soon and the sauce stays thin and the parmesan can clump.
4. Remove from heat and let stand for 3-5 minutes. It will look runny right off the stove — that’s normal and it tricks people into overcooking it. Give it a few minutes and it tightens up.
5. Pour over cooked, drained pasta and toss to coat. Serve immediately.

Serving Suggestions

This sauce goes with any pasta shape, but here is what works best:

• Fettuccine — the classic; the wide noodles hold the sauce well
• Penne — our family’s current favorite; easier to serve and eat, especially for kids
• Grilled chicken on top — slice chicken breast seasoned with McCormick’s Montreal Chicken seasoning and lay it over the plated pasta
• Shrimp — sauteed shrimp with garlic and butter is the other classic pairing

Storage and Reheating

The sauce and pasta mixture can be stored in the fridge for 3 days in an air tight container.

Reheating: Warm in the saucepan over low heat. Add a little heavy cream or milk. Whisk as it heats. Don’t microwave at high heat — the sauce can break and become greasy. Low and slow with added liquid keeps it smooth.

Freezing: Not recommended. Cream-based sauces don’t freeze well. They separate and become chunky and oily when frozen and thawed.

Frequently Asked Questions

Why is my alfredo sauce too thin?

There is no need to panic! Let it rest off the heat for an additional 3-5 minutes. It may look runny right off the stove, but give it some time, it will thicken significantly. That is quite normal. And, if it’s still thin after resting, it means it probably didn’t reduce long enough. If that is the case, put it back on low heat and whisk for another 2-3 minutes.

Why is my alfredo sauce grainy?

I almost always use parmesan cheese. Cheese that comes in a powdered canister doesn’t melt evenly because the anti-caking agents stay gritty no matter how much you whisk. Another cause is too much heat when adding the cheese. This can make the proteins seize. To avoid that, use freshly grated parmesan cheese and refrigerate the shredded parmesan. Also, make sure to lower the heat to medium-low.

Can I use half-and-half instead of heavy cream?

While that’s understandable, I’d disagree. A sauce that has less fat tends to be thinner, breaks more easily, and is less flavorful. It’ll work with what you have, just lower the heat and be prepared for a thinner sauce. Heavy cream is the better choice for this sauce and the difference is clear.

Can I add garlic?

Definitely, and I frequently do. Sauté 1-2 cloves of garlic in the butter before you add the cream. It might not be traditional alfredo but it sure tastes good and the garlic goes nicely with the sauce. Just be sure to not let it brown before you add the cream.

How much pasta does this sauce cover?

4-5 servings of cooked pasta. For a bigger batch, just double it — the ratios remain the same. One tip: save a cup of pasta water before draining. The water can be used to loosen the sauce if it thickens too fast after you toss it with the pasta.

Is this the same as Olive Garden’s alfredo?

Almost there. Olive Garden makes their own cream-butter-parmesan base. The cream dairy sauce is richer than the rest of the sauces due to the higher ratio of sauce to base. In about 15 minutes with ingredients you likely already have, this gets you 90% there. I’m not disputing him.
