Important Ingredients

Heavy Cream – Do your favorite soups and sauces have a silky smooth texture? Heavy cream is to blame for this. It is curdle-resistant, which means it won’t clump or chunk at high temperatures. No one wants that, believe me.

Cream Cheese – Cream cheese is the keto dream: high fat, low carb, and low protein. For a rich, creamy sauce, it’s a requirement.

Parmesan – Name something that doesn’t taste better when Parmesan cheese is added. Oh, no, that’s not possible. It’s buttery, salty, and thickens and cheesifies the sauce. Use fresh Parmigiano Reggiano if you truly want to improve your alfredo.

How Do You Make It?

The whole recipe and ingredients list can be found below, but you can also find a fast explanation of how to make this recipe precisely, as well as helpful tips and information!

  1. Melt the butter in a medium pot and sauté the garlic until fragrant. Stir in the heavy cream and cream cheese until well combined and thick, then gradually add the Parmesan cheese. Toss with a pinch of salt and pepper to taste.

Chef’s Advice

  • Garlic is easily burned, so keep an eye on it. As soon as the garlic is aromatic, pour in the heavy cream.
  • Bring the cream cheese to room temperature before creating your sauce to prevent clumping. When the cream cheese is too cold and the mixture is too hot, lumps form.
  • Because high heat might cause the parmesan to become stringy rather than smooth, remove the skillet from the heat when stirring in the cheese.
  • A side of keto green beans goes great with this alfredo sauce! Easy Healthy Recipes, our sister site, has my favorite keto green bean recipe.

Instructions For Alfredo Sauce

  1. In a medium saucepan, melt the butter. Cook garlic for 2 minutes, or until fragrant.
  2. Heavy cream and cream cheese should be added.
  3. Slowly mix in the Parmesan cheese until it is completely integrated and the sauce thickens about 5 to 7 minutes. Salt & pepper to taste.


  • Any cream cheese will do, however, due to the carb level, I recommend the Philadelphia brand. In this dish, 4 grams of carbs come from Philadelphia cream cheese, whereas 8 grams come from Kroger brand cream cheese.
  • Keep it Keto: To obtain that excellent pasta texture with only 2g net carbohydrates per serving, I like to use three cans of palmini noodles (or two cans if I want it extremely saucy). Shirataki noodles, zoodles (zucchini noodles), and kelp noodles are other excellent substitutes.
