  • Melt butter in a small saucepan on medium heat. Add garlic, salt, pepper, dijon and whisk. Slowly add in warmed heavy cream and bring to a simmer. Simmer for 15 minutes, whisking often to prevent burning.

Expert Tips

  1. Use unsalted butter to avoid a cheese sauce that is too salty. If you only have salted, taste test the keto cheese sauce before adding any salt.
  2. Refrigerate any leftovers. To reheat, the Keto Cheese Sauce can be microwaved until warm, and whisked to recombine the sauce (it will have separated). If the sauce has become too thick once reheated, a little heavy cream can be mixed in, about 1/2 tsp at a time, until the desired consistency has been reached.
