Ingredients in Low Carb Cheese Sauce

Most traditional cheese sauce recipes use flour as a thickener, making them off-limits for those on a low-carb or keto diet.

However, this homemade cheese sauce is thick and delicious without any extra thickening agents.  The recipe is so simple and calls for just a few wholesome ingredients: heavy cream, Cheddar cheese, a little Parmesan cheese, and mustard (either Dijon mustard or mustard powder will work!).

I like the flavor of Cheddar in this recipe, but you can substitute any other melting cheese that you prefer.

  • Gruyere is a classic choice.
  • Jack cheese is mild and creamy.
  • Pepperjack will give this sauce a little spice!

How to Make Keto Cheese Sauce

This recipe is so quick, you can make it while the broccoli is steaming.  All you need is a small saucepan and a whisk.

Start by heating the heavy cream over medium heat in a small saucepan. You don’t need to boil the cream, but do bring it up to a bare simmer. You want it hot enough to melt the cheese in the next step.

Reduce the heat to low, and stir in the grated cheeses, mustard, garlic powder, and pepper.  (Don’t add the salt just yet!)

Keep stirring until the cheese mixture is fully melted, smooth, and creamy!  Then, taste for salt, and add more as needed.  (A lot of the time, I don’t add much extra salt at all, since the Parmesan cheese makes it salty enough.  This, of course, will depend on the cheeses you choose.)

Remember that this sauce will start to thicken as it cools, so be sure to serve it warm.

How to Serve Keto Cheese Sauce

This sauce is amazing over broccoli or cauliflower. If you have some non-vegetable-lovers in your family, try converting them with some of this cheese sauce!

You can even pour over your favorite low carb noodles or roasted cauliflower for a keto mac and cheese alternative.

Reheating Keto Cheese Sauce

You can make this keto cheese sauce recipe ahead of time and store it in a lidded container in the refrigerator. It will keep for 3-5 days in your fridge, if it lasts that long.

To reheat the sauce, add a few more tablespoons of heavy cream, stir, and microwave in 30-second intervals — stirring in between.  You can also reheat it in a saucepan if you prefer.
