  • 1 pound boneless, skinless chicken breasts
  • 1/2 teaspoon salt
  • 1/4 teaspoon pepper
  • 1/2 cup blanched almond flour
  • 1 tablespoon butter

Creamy Spinach Sauce

  • 2 tablespoons butter
  • 1 shallot (finely diced)
  • 4 cloves garlic (minced)
  • 1 1/2 cups white wine (or chicken stock)
  • 1 cup heavy whipping cream
  • 5 ounces fresh spinach
  • 1/2 cup Parmesan cheese (grated)
  • fresh parsley (optional, garnish)



  • Season the chicken with salt and pepper. Dredge each piece in the almond flour to coat both sides.
  • Melt 1 tablespoon of the butter in a large skillet over medium-high heat. Cook 2-3 minutes per side, until golden brown and cooked through. Chicken should reach an internal temperature of 165°F on a meat thermometer inserted into the center of the thickest portion. Remove to a clean plate.

  • Add the wine and raise the heat. Reduce by half, scraping up any browned bits from the bottom of the pan. Once reduced, stir in the heavy cream. Cook a few minutes to thicken.

Tips and Techniques

  • You can use chicken thighs, if you prefer. They may take a little longer to cook.
  • Fresh spinach is recommended for the best results. If you have to use frozen, be sure to thaw it and squeeze out as much moisture as you can before adding it to the sauce.
  • Store leftovers in an airtight container in the refrigerator. Use within 3-4 days.
