Keto alfredo sauce

Keto Alfredo Sauce

Many of the store bought sauces and condiments use starches and flours that increase the carbohydrate count. But you can very easily make your own sauces at home, usually for a fraction of the cost and carb count! This homemade keto Alfredo sauce is a perfect example—and it’s better than the stuff you’ll find in a jar at the stores!
