  • Cut the chicken breast into 1-inch cubes and sprinkle with onion powder, garlic powder, salt, and pepper.
  • In a skillet over medium high heat add your olive oil and the cubed chicken. Cook for approximately 10 minute, or until chicken is cooked through. Set aside.
  • Steam the broccoli. Place cut broccoli florets in a microwave safe bowl with 1 cup of water. Cover with a damp paper towel and microwave on high for approximately 3 minutes or until the broccoli is fork tender. Don’t overcook!
  • Drain the broccoli and pat dry with a paper towel. Set aside.
  • Preheat oven to 350 degrees F.
  • In a small pot heat the keto alfredo sauce over medium low heat. When it is hot add 3 ounces of mozzarella cheese to the sauce and stir until it is melted and the sauce is smooth.
  • Prepare a 13×9 inch casserole dish by spraying it with non-stick spray then spread ½ cup of keto alfredo sauce on the bottom.
  • Next add half of the broccoli to the dish making a layer of it on the bottom.
  • Top with half of the cooked chicken. Let the chicken fill in the spaces between the broccoli to fill the dish.
  • Pour ¾ cup of keto alfredo sauce over the broccoli and chicken.
  • Sprinkle 4.5 ounces of mozzarella on top.
  • Repeat steps using the remaining broccoli and chicken to make a layer, followed by the remaining keto alfredo sauce, and topped with the last of the mozzarella cheese.
  • Place in oven and bake for 30 minutes, or until the casserole is warmed through and the cheese is fully melted.
