Let's make a delicious low carb sauce that will knock your socks off. Not only is this sauce creamy, it packs a delicious and flavorful punch! The taste reminds me of Olive Garden alfredo sauce with its parmesan richness. Bonus, this keto alfredo sauce only has 2 net carbs!


  • Butter - 1.25 Tablespoons
  • Garlic - 1 Clove
  • Heavy Whipping Cream - 1.25 Cups
  • Parmesan Cheese - 3/4 Cup
  • Soft Cream Cheese Spread - 1/3 Cup
  • Salt - 1 TSP
  • Pepper - 1 TSP
  • Parsley (or Basil) - 1 TSP


  1. Place butter and garlic into a sauce pan and melt. Whisk together to create garlic butter sauce.
  2. Once garlic butter is melted, mix in heavy whipping cream (HWC), parmesan, cream cheese (softened), salt, pepper and optionally parsley or basil.
  3. Stir together on medium heat for approximately 5 minutes.
  4. Alfredo sauce should be a thick, creamy consistency.
  5. Taste and flavor to your liking.


Make this keto alfredo sauce to your liking! If you prefer a salitier version, add more salt. Like garlic? Increase the garlic.

If you desire an extra thick alfredo sauce, try adding in egg yolks.


GARLIC - If you don't have fresh garlic, use granulated or powder garlic. I keep chopped garlic in my fridge, this is a great alternative / substitute for garlic cloves.

HEAVY WHIPPING CREAM - HWC: Milk can be used to replace heavy whipping cream, but do note it will not be as thick. Another alternative is using sour cream. Again, it will not be as thick, but when times are desperate use what you can!

DRIED HERBS - while I add parsley or basil to my alfredo, feel free to add whatever you have in your spice rack that you like! Italian seasoning is a great alternative as it typically has parsley and basil (and garlic too!)
