This is a classic flavorful sauce that the whole family will enjoy.Is Alfredo sauce Keto?A classic homemade Alfredo sauce is often Keto compliant, as the base of the sauce is simply cream, parmesan, garlic and butter. However, there are many many variants on an Alfredo sauce, some of which use carb-heavy flour as a thickener or milk to thin the sauce. To keep our Alfredo sauce quick and Keto friendly, we have used a combination of butter, garlic, heavy cream, soft cream cheese and grated parmesan. This simple combination not only packs a flavor punch but also makes an incredibly smooth and creamy Alfredo sauce.Serving SuggestionsThis quick and easy Keto sauce is incredibly versatile and will pair well with multiple Keto meals. We love our Alfredo stirred through low carb pasta noodles or in place of a bechamel sauce in a Keto lasagna. This also makes a wonderful addition to your Keto casseroles and bakes, perfect with low carb vegetable gratins and baked meatballs. The sauce is so rich and creamy that it could even be used as a decadent dip for low carb veggies!

How to Make It

Step 1

Add the butter to a medium saucepan. Set over a low/medium heat to melt the butter. Crush the garlic. Add the garlic to the saucepan with the melted butter. Gently sweat over a low heat for a minute or two until tender and fragrant, taking care not to burn the garlic.

Step 2

Add the heavy cream, soft cream cheese, grated parmesan, salt and pepper. Feel free to adjust the quantities of salt and pepper to your personal tastes. You may also add dried herbs such as parsley to your sauce for extra seasoning if you wish. Be sure to adjust your macros for any additions.

Step 3

Whisk the ingredients together gently but thoroughly over a low/medium heat. Gently cook the sauce until piping hot through. The sauce should be smooth and creamy. Taste, and adjust seasonings as needed. This makes a thick and rich Alfredo sauce. If you would prefer a thinner sauce you may add a little stock or water to thin as desired. Stir through low carb pasta or alongside your favorite Keto meals.
