Depending on the coconut milk you will use, the final result may be a bit liquid.

For a thicker sauce and binding you can add almond flour, which keeps sauce low carb.

Of course you can also use another thickener. Any other flour will do but add more carbs to the sauce.

How to make Alfredo sauce keto

In a sauce pan or casserole, first melt vegan butter. Fry the garlic for around 2 minutes before adding the optional almond flour to it, if you aim for a thicker sauce, otherwise leave it out.

Finally add all the other ingredients like coconut milk, vegan mayo, and nutritional yeast. Season with salt and pepper, bring to a simmer while stirring. Let it cook on low heat for 5 minutes until the sauce thickens. Serve over pasta, zoodles or anything else and enjoy.

It makes such an amazing comfort for everyone. Only recently I served this to a bunch of friends and no one could taste and tell the difference.

Pro tip as you can see in my step by step pictures, my sauce came out smooth and creamy, If it does not, you can blend this sauce in a food processor or blender.

Variations and low fat option:

Keto Alfredo sauce with cream cheese: recently I swapped out the vegan mayo for dairy free cream cheese and it was amazing. So rich and creamy, but honestly the vegan mayonnaise is what gives this sauce the tang. Which is something you can’t achieve with the cream cheese. 

Keto meal plan: Did you know you can make this sauce in advance for easy peasy meal prep? Yes, don’t hold back from casseroles, pasta dishes, I can even imagine it is delicious on salads or just over vegetables.

Fresh chives are used to decorate the dish.

Instant pot Alfredo: firstly add vegan butter, garlic saute for around 2 minutes, now add coconut milk, optional almond flour, nutritional yeast season with salt and pepper. Now use your setting to high pressure, seal the lid. After 4 minutes open the lid and add vegan cream cheese and vegan mayo. Stir and serve.

Note as I always say, this is the just the cooking time so it does not included the time which is needed for the instant pot to reach high pressure.

Enjoy a vegan and keto Alfredo Sauce!

Slow cooker Alfredo: just add all the ingredients in your slow cooker, set the preferred time and it is all done.

Low fat Alfredo: just swap the vegenaise for dairy free yoghurt and the coconut milk for another plant milk. Also reduce dairy free butter to 1/2 teaspoon.

This Keto Alfredo Sauce is super rich and creamy. Made with simple ingredients, nut free and no one would ever guess it is vegan.

This looks great! Looking forward to trying it. Do I use light or full-fat coconut milk?

Florian

I made this over the weekend and it tasted great! How well does the sauce freeze?

Florian

Tuesday 10th of March 2020

Hi Rebecca! I haven't tried that but I would say probably not. Ingredients are not the best to freeze. But you can store it in the fridge with a lid on top for around 5 days. Hope that helps.
