BEST Low Carb Keto Alfredo Sauce

An easy, delicious alfredo sauce recipe that's keto-friendly. It uses heavy cream instead of milk and is made without flour. The garlic gives this sauce the perfect flavor that you’ll usually get from a traditional alfredo dish. This would be great with zoodles, konjac noodles, palmini pasta or any other low carb pasta substitute like spaghetti squash!

  • Medium Sized Pot


  • ½ cup unsalted butter
  • 4 cloves garlic or more
  • 1.5 cups heavy cream 35% or higher
  • 2 cups parmesan cheese grated
  • ¼ tsp salt
  • ¼ tsp black pepper coarse
  • ¼ tsp nutmeg
  • 2 tbsp chopped fresh parsley


  • Mince the garlic and chop the parsley. Grate your parmesan if you haven't already.
  • Add the butter to a medium sized pot and heat on medium heat. Add the garlic and cook until tender.
  • Lower the heat to low-medium. Add the heavy cream and stir together. Wait until the cream starts to bubble before adding in the cheese.
  • Once the cream is bubbling, add the parmesan cheese a little at a time while constantly stirring. I did this in 3-4 batches. The more cheese you add, the thicker the sauce will become. Don't add all of the cheese at once as it can clump together.
  • Once all of the cheese has melted, add all of your spices and herbs and stir together. The sauce is now ready to serve over your favourite pasta, in casseroles or on pizzas!
