  • 1 cup heavy cream
  • 1 1/4 cups shredded cheddar cheese
  • 1/4 cup mascarpone cheese
  • 1 tablespoon grass-fed butter
  • Zest of 1 lemon
  • 1/2 teaspoon pepper
  • 1-2 teaspoons of salt to taste


  • Add the butter to a sauce pan on medium heat. ¬†Add in the heavy cream and heat for a minute. ¬†Then add in the mascarpone cheese, salt and pepper.
  • Once the mascarpone is melted, add in the cheddar cheese and stir.  Cook over medium low heat for a few minutes, or until the sauce has thickened to your liking.  Mine took a little over 3 minutes.  
  • Once thickened, add in the lemon zest and serve.


Optional: If serving with broccoli or asparagus, I highly recommend adding the zest of 2 lemons.
