Life-Change Gluten-Free Alfredo – Back Pocket Recipe
Who doesn’t love a velvety, creamy alfredo sauce? If you think just swapping in gluten-free pasta for a traditional recipe will get you there, use a little caution. For instance, Olive Garden’s alfredo sauce uses a roux to make their sauce, which means equal parts butter and flour. (No good for GF peeps.)
A traditional fettuccine alfredo, though, has no gluten. (Yay!) It’s simply pasta, butter, and parmesan cheese, mixed with a little pasta water to make it smooth. While it seems easy, this technique requires a little finesse to keep the sauce smooth.
If you are looking for an easy homemade gluten-free Alfredo option (hello, copycat Olive Garden!), you are in luck with our family-favorite recipe. I use it for chicken Alfredo, dipping sauce for these doughy soft gluten-free breadsticks, as a white pizza sauce, or as winning weeknight dinner idea – change up the marinara for Alfredo in this quick and easy gluten-free-pasta bake.
Wow!!! Best Alfredo I’ve ever had!! I made a little extra sauce and added broccoli and chicken to it too!!

Ingredients Tid Bits
The ingredient list is short and affordable, it comes together in less than 10 minutes, and makes a predictably smooth, creamy sauce that never breaks. Similar to the lemon cream sauce in creamy lemon chicken pasta, this gluten-free cream sauce uses no flour.
- Heavy cream – I highly recommend using the heavy cream for a richer tasting cream sauce. Half and half or whole milk may be substituted, but will result in a thinner sauce.
- Butter – Salted butter will give the alfredo an extra oomph of flavor.
- Cream Cheese – Using full-fat cream cheese breaks down better without lumps. If using light cream cheese, be sure to cube and soften it before adding to the Alfredo. Since there is no roux, the cream cheese naturally thickens the sauce, as well as emulsifies it so you don’t risk it breaking with accidental overheating or with reheating.
- Parmesan Cheese – Use freshly grated, not canned or pre-grated. They contain cellulose, which will make your sauce lumpy.
- Flavor – A dash of nutmeg, garlic, salt, and pepper.
Let’s Make This Together!
(Below shows step-by-step photos and modified instructions. For the complete recipe, along with ingredient amounts, scroll down to the recipe card.)
Be prepared. This goes fast!
Before beginning, be sure the noodles are boiling. The sauce comes together quickly and you will want to make sure your pasta is cooked and ready to toss with the sauce.
Place the butter, heavy cream, softened cream cheese, garlic, nutmeg, salt, and pepper in a medium saucepan. Cook over medium heat, whisking until the butter and cream cheese melts.
Creamy, cheesy finish
Add the grated parmesan cheese and whisk until smooth. Reduce the heat to medium-low and simmer for 3-5 minutes, or until it starts to thicken. Drain your pasta and toss all that goodness. Donezo!
Want a thicker sauce? This recipe is the perfect consistency for tossing with gluten-free pasta. However, if you are looking for a thicker sauce for dipping or as a pizza base, consider simmering it longer to reduce, adding arrowroot powder or cornstarch, or whisking in an egg yolk.
Bonus Tips & Troubleshooting
What’s the best gluten-free pasta to serve with Alfredo? If you are looking to pick up something quickly from the local grocery store, then I recommend Barilla gluten-free fettuccine. But, if you want something that is completely exceptional (like, can’t tell it’s GF), I highly recommend getting some Rummo gluten-free pasta in every shape and size and keeping it on hand.
For a more luxurious, company’s-coming meal, then tossing my authentic from-scratch gluten-free pasta with Alfredo is the ultimate chef’s kiss!
Why is my sauce lumpy? Using a lower fat cream, such as milk or light cream cheese, can do this. Also, be sure your cream cheese is room temperature, and for best results cube it before adding to the sauce.
How much pasta should I cook? Gluten-free pasta is sold in 12 ounce boxes, rather than the one pound traditional pasta boxes. Therefore, this recipe is scaled to the perfect amount of sauce for a box of gluten-free fettuccine noodles. The recipe notes do contain the ingredient amounts for one pound of pasta, if needed.

Notes
storing and reheating tips
If you don’t plan on eating the entire fettuccine alfredo recipe, I recommend refrigerating leftover sauce before it has been tossed with the noodles. It will keep up to 5 days in an airtight container. To reheat the sauce, the best method is on the stovetop. Place it in a saucepan (heavy-bottom triple-ply stainless works best) and reheat gently, over low heat, whisking frequently. If the alfredo has been mixed with the noodles, there are several recommended ways, such as heating with steam (using a double-broiler), in the oven, or using a microwave. I will say I have tried all three and the easiest, plus best results came using a microwave. But, there is an important tip! If you heat on full power the butter will separate, leading to greasy leftovers. The key to reheating is using microwave defrost! Heat at no more than 30% power, cook for 1 minute, then stop to stir every 30 seconds until heated through.This post contains affiliate links. My opinions are always my own.

This sounds so perfect! My Question: How would this hold up in a lasagna? I want to make a pan of lasagna for a couple who cannot do tomatoes. I figured I’d assemble and bake and freeze. This way, they can thaw and rebake at their leisure. I’m always afraid of that “separation factor” which can happen. It seems to me that the cream cheese would put an end to my fear? Please advise! Thank you so much!
Hi Mary,
I think that’s a great idea and sounds so yummy! In a lasagna you wouldn’t have to worry as much about a separation and the cream cheese does help stabilize it. I would recommend assembling it, cooling everything, wrap, and freeze. Then when you are ready to serve, let it thaw (this will take probably 1 1/2 days at least – you can speed it up by setting it at room temp that last few hours), and then bake it. I worry about it baking and then essentially baking again when you reheat it.
Best,
Melissa
OH! You’re a genius! Yes — why would I bake it the first time? I guess I was thinking about reheating leftovers (which, duh- are previously baked by default) You are a Goddess! Your fast reply has saved me a lot of potential heartache! God bless you, dear Lady! ❤️❤️❤️
Best fettuccine alfredo I’ve ever had!

Husband and I were looking for something different to do on homemade pizza. I found this recipe along with a chicken bacon ranch and made 2 pizzas. I had to eat the chicken ranch which was sub par to this recipe. Husband loved this on whole fresh cracked wheat pizza!!!!!! I really liked it also, but he needs to gain weight and this has lots of fat and calories for him! Thank you for the recipe and we will be enjoying again soon.
Oh my gosh, my mouth is watering thinking about that pizza! That sounds absolutely amazing. Thanks so much for sharing!
Best,
Melissa
I made a slightly altered version, but used the cream cheese instead of flour (roux). It stayed creamy and did not get clumpy and pasty when it cooled. When I had made a recipe with a roux, the final product was a little grainy. This was silky smooth and had a great flavor. Cream cheese is the way to go for Alfredo.
Thanks, Vic! I’m so glad you enjoyed the recipe!
Best,
Melissa
