This low carb chicken dinner recipe is just dang amazing!  So flavorful and satisfying even though it is healthy.




  • 5 boneless, skinless chicken breasts
  • 2 teaspoons koshersalt
  • 1/2 teaspoon pepper
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 6 ounces fresh mozzarella cheese, sliced


  • 8 ounces mushrooms, sliced
  • 2 Tb butter
  • 2 large cloves garlic, minced
  • 1/2 C water
  • 2 tablespoons red wine vinegar
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon pepper


  • 1012 ounce bag of spinach leaves
  • 4 ounces cream cheese
  • 1/4 C shredded parmesan cheese
  • 2 large cloves of garlic, minced
  • 1 small onion, chopped
  • 2 Tb oil
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon pepper


  1. Preheat oven to 350 degrees. Spray 9×13 casserole with nonstick spray. Generously season the chicken with salt, pepper, garlic & onion powder. Place in the casserole, skin side down and bake for 16 minutes.
  2. Toppings: While the chicken bakes, prepare the mushrooms and spinach. In a large skillet over medium high heat, melt the butter then add the mushrooms. Cook until the mushrooms are browned all over. Don’t add the salt before they brown, or they won’t brown at all! Add the garlic once the mushrooms are browned and cook for 1 minute, then deglaze the pan with the water/vinegar mixture. Add salt and pepper then allow it to reduce until most, but not all of the liquid is gone. Remove mixture from the pan into a bowl and set aside until the spinach is finished.
  3. Spinach: Using the same skillet, add the oil and onion over medium high heat for 3 minutes. Add the garlic, cook for 1 minute then add the spinach in batches. It will shrink down as it cooks. Once all the spinach has been added and cooked down, stir in the cream cheese, parmesan, salt and pepper until they melt and mix together. Add in the mushrooms and stir.
  4. Bake: Remove chicken from the oven and flip over so the skin side is now up. Slather on the spinach/mushroom mixture evenly over the top of the chicken. Lay the sliced mozzarella cheese evenly over the top and return to the oven for 13-15 minutes more or until the chicken is cooked through.
