  • 2 lbs boneless skinless chicken breasts thin cut
  • 1/2 small onion
  • 2 garlic cloves minced
  • 8 oz sliced mushrooms
  • 2 tablespoons butter + 2 tablespoons butter divided
  • 1 1/2 cup chicken broth
  • 1/4 cup heavy whipping cream
  • 1/2 tsp salt
  • 1/2 tsp pepper
  • 1/8 tsp xanthan gum
  • 1 1/2 cup mozzarella cheese grated
  • 1/2 cup parmesan grated
  • 1 tsp Italian seasoning


  • Preheat oven to 450 degrees.
  • Grease a 9X13 casserole dish.
  • In a large cast iron skillet, melt 2 tablespoons of butter and saute the mushrooms, garlic, and onions on medium-high heat for approx 10 minutes until onions are translucent and mushrooms are very tender.
  • Remove from skillet and set aside.
  • Melt 3 tablespoons of butter in the same cast iron skillet and sear chicken breasts or tenderloins 3-4 minutes on each side so that they are nicely browned.
  • As each piece is browned, remove from skillet and place in the casserole dish leaving all of the drippings in the skillet.
  • Once all the chicken has been browned, add mushroom mixture back to skillet along with chicken broth, heavy whipping cream, and salt/pepper.
  • Cook on medium-high heat scraping the bottom of the skillet while stirring continously for 5 minutes.
  • Turn off the stove. Sprinkle 1/8 tsp xanthan gum on top and allow the sauce to thicken. It will take 5-10 minutes for the sauce to thicken just a bit. It will still be a bit broth-y as you don't want it to thicken too much. You can also omit the xanthan gum as it does not change the taste of the dish. 
  • Once it has thickened just a little spoon over chicken in the casserole dish.
  • Sprinkle parmesan cheese over chicken first, then top with mozzarella.
  • Top with 1 tsp Italian seasoning.
  • Bake in a 450 oven for 12-14 minutes.
  • To brown mozzarella, move casserole dish to top rack and turn oven to broil for 1-2 minutes.
  • Serve!
