The Best Keto Alfredo Sauce

When I’m craving carbs, a rich and creamy sauce can satisfy all the cravings. Sure, I could make a low carb lasagna or a deep dish pizza but I’m a simple man and I love some alfredo sauce.

This keto alfredo sauce recipe is one you’ll keep in your memory bank to make anytime and anywhere.

It’s made with just 4 ingredients: butter, heavy cream, parmesan cheese, and garlic. That is it.

It’s ready in just 10 minutes and it’s super versatile in tons of recipes or over various proteins: chicken breast, salmon, and even pork chops.

The texture is on point. It’s rich, creamy, and full of flavor.

Oh, and each serving is has less than 1 gram of carbs. Toss it through some keto pasta for a low carb dinner!

Ingredients needed

The beauty of this recipe is just how simple the ingredient list is. If you’ve made any of my other keto recipes before, you probably already have everything in your kitchen!

  • Butter- Unsalted butter. Use a very good quality butter, as the flavor really shines through. 
  • Heavy cream- Also known as thickened cream or double cream. Avoid using reduced fat or low fat varieties, as it will yield a more watery sauce. 
  • Parmesan cheese- Freshly grated or refrigerated parmesan cheese. Do not use the shelf stable variety, as it won’t melt and it will leave the sauce gritty. 
  • Garlic- Freshly minced garlic. 

How to make a keto alfredo sauce

Two simple steps are all you’ll need to follow this recipe.

Whether you are a beginner cook or a full-fledged chef, this sauce will turn out perfect.

Step 1- Prepare the sauce base

Start by adding the butter into a small saucepan and placing it over low heat. Once melted, add the minced garlic and cook for 1-2 minutes, until fragrant. Gently stir through the heavy cream, and slowly mix, until it simmers.

Step 2- Fold through the cheese

Let it simmer for 3-4 minutes, allowing it to thicken. Remove from the heat and fold in the parmesan cheese. Let the cheese melt into the sauce before serving it over your favorite entrée or main course.

  1. It’s the best. It’s real pasta but there’s tons of fiber in it. It doesn’t raise my blood sugar either. The key to making it low sugar is not to eat too much on one sitting.

  2. 5 stars
    Love this recipe! We love to eat spicy so I added cajun seasoning and dried cilantro flakes. Delicious! We are eating low-carb so I paired it with shirataki noodles.

  3. The pasta at carbzone.co.uk (carbzone.se for the Eurozone; other websites for other locations appear to be available) is the best-tasting, is prepared like normal pasta, and doesn’t raise my blood sugar any more than a regular low-carb meal does. Not for the gluten-free crowd though as part of the reason it perform so well is that the manufacturers add back the missing wheat gluten. Fortunately I, like most people, have no issues with gluten.

  4. 5 stars
    This is banging!!
    Do you want it a little thicker?
    Add some more cheese!
    I will be making this again!!

  5. You can also make the Alfredo Sauce with Almond milk as well, substituting for the dairy cream. I can’t have dairy.

    1. Whichever diabetic friendly pasta you can have. I’m not a medical professional so I don’t feel comfortable suggesting any, even if they are low carb or keto.
