Homemade Alfredo Sauce Recipe

Alfredo is one of our favorite dinners around here but most classic alfredo sauces leave me feeling completely weighed down. Plus they don’t tend to reheat well.

So my version uses milk in place of half of the heavy cream, and instead of using a full stick of butter I’ve found 3 Tbsp is just enough to keep it rich and creamy. And since I’ve made these adjustments it’s thickened up with just a hint of flour.

Then the one thing I choose not to be skimpy on in this recipe is the parmesan cheese, because alfredo sauce is all about that parmesan! I also like to add 1 clove of garlic (sometimes 2) because who doesn’t love garlic? But if you’d prefer you can omit it altogether.

This is just makes one of those dinners that is 100% comforting and satisfying and seems almost too good to be true! It’s perfect for long busy days and weekends too. Any day of the year is a good day for fettuccine alfredo!

Is it Authentic?

You may be wondering, is this authentic alfredo sauce? No it’s closer to the American version. Usually the traditional, authentic Italian alfredo sauce is made with just Parmesan cheese, butter, pasta water and salt. Which is delicious but why not add cream and milk to make it even richer?

What Ingredients go into Alfredo Sauce?

  • Parmesan cheese – for best results us real parmigiano reggiano. You know, that kind cut from the big giant Murray’s cheese wheels at the cheese counter of the grocery store. Whatever you do, don’t use grated powdered parmesan or pre-shredded parmesan with the powdery coating. They won’t melt into the sauce (plus they won’t taste good here either).
  • Heavy cream – look for “heavy cream” or “heavy whipping cream” on the label. “Whipping cream” doesn’t have the same amount of fat so the sauce wouldn’t be as rich.
  • Whole milk – skip lower fat percentages of milk for a deliciously creamy sauce.
  • Butter – unsalted or salted butter will both work great here.
  • Flour – this thickens up the sauce a little. At first the sauce may seem a bit runny (even though we add the flour) but as it tossed with starchy pasta and as it cools it will thicken right up. I’ve found I like just 1 Tbsp flour, use anymore and by the end of dinner the sauce is much too thick.
  • Garlic – if you choose to use garlic go for the fresh stuff and skip powders or pre-cut garlic. It’s all about building and bringing the best flavors together.
  • Salt and pepper – add these to taste. Keep in mind parmesan cheese is pretty salty so you shouldn’t need a whole lot of salt.

How to Make this Easy Alfredo Sauce:

  • Make roux: Melt butter in a large, deep skillet (or saute pan) over medium heat. Add flour, cook 30 seconds stirring constantly, then add garlic and saute until flour and garlic are golden, about 30 seconds longer.Sautéing flour and garlic in butter in a skillet.
  • Add dairy liquids: While whisking slowly pour in heavy cream and milk. Cook stirring constantly until mixture simmers and thickens slightly.

  • Stir in cheese: Remove from heat, stir in Parmigiano-Reggiano. Return to low heat, stir until cheese has melted through.

  • Keep warm: Cover and keep warm over warm heat, stirring occasionally, until pasta is finished.
  • Toss with pasta: toss sauce with fettuccine or other pasta of choice. As it rests sauce will thicken upon standing, it can be thinned with warm pasta water.

How Can I Make it Lighter without Cream?

Yes. You cane make alfredo sauce with milk only. If doing so here use 1 1/2 cups whole milk and increase flour to 2 Tbsp. Parmesan can be reduced to 1 cup. Just note that the sauce won’t be as rich with these changes.

How to Make it Richer?

Want to go the extra rich route? Replace the milk with more heavy cream (using 1 1/2 cups total), omit the flour. Melt butter and saute garlic 30 seconds, add cream and bring to a simmer. Let simmer over low heat about 3 – 4 minutes (to reduce slightly), then stir in parmesan cheese and melt through.

Tips:

  • Let butter brown just a bit for added flavor.
  • Be careful not to burn the garlic, that can add a bitter flavor to any dish.
  • Use best quality parmesan.
  • Slowly add cream and milk so sauce thickens properly.
  • Add parmesan off heat, then fully melt through over low heat so it doesn’t clump and separate in the sauce.

Variations:

  • Use half and half in place of cream and milk.
  • Add grilled chicken or shredded rotisserie chicken, who can resist Chicken Alfredo?
  • Add sautéed shrimp. I mean why not? It cooks in about 3 minutes in a skillet.
  • Like spicy food? Add red pepper flakes to your hearts content.
  • Try it with half Romano cheese in place of parmesan cheese.
  • Make it extra special with fresh fettuccine instead of dry if you have access to it. Use 1 lb.

How Many Cups Does this Yield?

This recipe makes about 2 cups of sauce, or enough for 10 – 16 oz. of dry fettuccine pasta (depending on how saucy you like it, I like to use 12 oz).

      Can’t go wrong with more garlic! Love to know your family enjoyed!

  • Megan

    Absolutely love this sauce! Just curious as to how you stop the butter separating from the rest of the sauce by the end of making it?!

      Don’t let the sauce get too hot or it can separate, also you can try adding in just a little more flour.

  • Bonnie

    My daughter got her first job today. She asked for Alfredo to celebrate. This recipe delivered! Mom feeling like a rockstar cook and daughter finishing her plate with a smile. Served with chicken breast and broccoli. Amazing what a few quality ingredients can make! Will add this recipe to my list of make again.

  • Mary

    Do you use a whole bag of cheese? The bag said 1.5 cups as 6 oz, the recipe says 1.5 cups as 4 oz. I just poured the whole bag in but it took a long time to get to a good consistency and tasted a bit too cheesy for me but my family loved it.

      What I recommend is to use freshly grated cheese for better melting and flavor. So glad your family loved it though!

  • Amber

  • Juna

    This is the best Alfredo-like pasta recipe I’ve ever made! Garlic and Parmesan gives it a unique taste like no other! Family really loved it!

    I did not use regular milk, instead, I substituted it for half-and-half for an even creamier sauce
