My husband is a total Chicken Alfredo fiend, you guys.

I swear, he would drink Alfredo sauce if he didn’t think I’d judge him for it.

And, okay, let’s be real. I’d drink it too. It’s such a simple little sauce to make (don’t be scared!!) but it packs such a creamy, flavorful punch!

Today, I’m sharing my keto Alfredo sauce recipe with you and I’m sharing my favorite way to serve it up: over broccoli!

Have you guys caught on that we’re big fans of broccoli in this house?

I feel like most people assume low carbers eat cauliflower all day long and while I definitely do have some cauliflower tricks up my sleeve, it’s broccoli that we come back to again and again. Especially when it’s topped with chicken and drizzled in Alfredo.

Another favoreite way to enjoy our keto alfredo sauce is with spaghetti squash. Our spaghetti squash Alfredo is an easy recipe, and a fun way to get that pasta vibe!

Why We Love This Keto Alfredo Sauce:

Our keto Alfredo sauce is really just the same as traditional Alfredo sauce – there’s no difference other than how we serve it up! This sauce is rich, creamy, smooth, and flavorful.

To make it keto, we skip the pasta and serve the sauce over steamed broccoli.

Low Carb Alfredo Sauce – The sauce is pretty simple to make but it is loaded with flavor! Heavy cream, butter, garlic, salt, pepper, and of course lots of shredded Parmesan are what make this homemade alfredo sauce taste so great. Be sure to use shredded Parmesan and not the grated powdery stuff in the green can!

Chicken & Broccoli – If you need something keto friendly to serve this sauce over then try fresh steamed broccoli and thin sliced seasoned chicken breasts. The perfect combo!

Cream Cheese

While authentic Alfredo sauce does not contain cream cheese, it’s become quite popular to add it for extra creaminess and richness! I don’t always add it, but if I have an extra bit of cream cheese that I need to use up, it really does amp up the sauce! Go ahead and try it – just stir up to 2 ounces of cream cheese into the hot butter and cream mixture and let it melt!

How To Make Keto Chicken Alfredo:

  • Make the Chicken: Season up your chicken breasts with a mixture of paprika, garlic powder, salt, and pepper. Simple, but flavorful! seasoned chicken on white plate
  • Cook the Chicken: Heat a large skillet with a bit of oil and then drop in your chicken. Cook through.seared chicken in cast iron skillet
  • Steam the Broccoli: While the chicken is cooking, start the broccoli. You’ll want to steam it until it’s tender-crisp.
  • Make the Alfredo Sauce: Heat the cream, butter, and garlic in a small sauce pan until the butter has melted and the cream is hot. Turn off the heat and stir in the Parmesan. Keep stirring until the sauce is smooth and creamy.

Is Alfredo sauce keto?

Yes! Traditional Alfredo sauce is naturally low carb and keto friendly, because it’s just a mixture of butter, cream, and Parmesan cheese. The sauce you’ll find at most popular restaurants often do contain flour, so double check if you’re not making it yourself.

Can I store this Alfredo sauce for later?

Alfredo Sauce is best served fresh. The sauce tends to separate as it sets and cools. If you must save this for later, store tightly covered in the fridge and reheat on the stove over low heat, whisking constantly. You may need to add additional cream to bring the mixture together as it reheats.

One batch of our Alfredo sauce has 5 total carbs, breaking down to just over 1 carb per serving.

Keto Chicken Alfredo

Traditional Alfredo sauce served over chicken breasts and steamed broccoli! Who needs pasta?

Yield 4 servings
Prep Time 10 minutes
Cook Time 20 minutes
Total Time 30 minutes


For the chicken:

  • 1 pound thin sliced chicken breasts
  • ½ teaspoon salt
  • ½ teaspoon ground pepper
  • ½ teaspoon paprika
  • ½ teaspoon garlic powder
  • 1 tablespoon avocado oil

For the broccoli:

  • 16 ounces broccoli

For the Alfredo sauce:

  • 1/2 cup heavy whipping cream
  • 1/4 cup butter
  • 1 teaspoon minced garlic
  • 1 cup shredded Parmesan


To make the chicken:

  1. Sprinkle the salt, pepper, paprika, and garlic powder evenly over both sides of the chicken.
  2. Heat a large skillet over medium heat and add the oil.
  3. When oil is hot, add the chicken breasts and cook 5 minutes on each side or until chicken is cooked through.

To make the broccoli:

  1. While chicken is cooking, steam the broccoli on the stove or in the microwave until as tender as you'd like.

To make the sauce:

  1. Heat a sauce pan over medium heat and add the cream, butter, garlic, salt, and pepper. Whisk constantly until the butter is melted and the mixture is hot.
  2. Remove from the heat and stir in the shredded Parmesan. Whisk until the cheese melts fully and the sauce is smooth.
  3. To serve, divide the broccoli between four plates and top with chicken. Drizzle with sauce.


Alfredo sauce is best eaten right after preparation. It does not store or reheat well as it tends to separate a bit.

If you'd like to add cream cheese to the sauce, stir up to 2 ounces of cream cheese in with the hot butter and cream until melted. Proceed with the Parmesan.

Nutrition information is based on the sauce, broccoli, and chicken. The carb count on just the sauce will be much lower.

  1. This tastes great and only took about 45min to make (and I am a slow cook). I used a meat mallet on the chicken breasts and only had to cook them about 2 min on each side. Thank you for the recipe.

  2. The recipe shows salt and pepper but the directions show it being used on the chicken AND the sauce. How much salt and pepper for just the sauce?

    1. Karly Campbell

      Oh, sorry about that! We just add a pinch of each. The cheese is already fairly salty, so you can make the sauce and taste and add as needed.

  3. This was delicious! Added 1 T. of cream cheese to the sauce, but otherwise followed it exactly. 5/5 kids approved! (And want me to make it again!).

    1. Karly Campbell

      Oh goodness – that should definitely say Alfredo. Haha! Thanks for the catch.

    1. Karly Campbell

      Uh oh! Are you sure you measured right and followed the instructions? Sounds like not enough liquid or too much cheese?

      1. Kathy Steinlicht

        Did you use grated or shredded Parmesan cheese? If using grated, it only takes about 1/3 cup. Using 1 cup of grated Parmesan cheese would make it thick and doughy. I didn’t have any shredded Parmesan, so I just used less of the grated and it turned out great.

  4. This was absolutely the best! simple and so delicious Thanks so much for sharing this recipe

    I have been trying to pin this recipe, but all I get are pictures, not the full recipe. Have not had this happen before when pinning recipes from your site. This looks and sounds delicious and I would like to save it so I can have it for the future.

    1. Karly Campbell

      Hmm, I’m not sure what you mean. When you pin it, you should just be pinning one of the pictures of the recipe. Is that not what’s happening? To get to the recipe, you’d click the pin and it would take you to my site.

        Hi Patricia! I haven’t measured this by volume. We just divide it evenly into 4 servings.
