Equipment

  • 1 large mixing bowl
  • 1 9x13 inch baking dish
  • 1 skillet
  • 1 whisk
  • 1 measuring cups and spoons
  • 1 cutting board

Ingredients
  

  • 1.5 lbs boneless, skinless chicken breasts
  • 2 cups fresh broccoli florets
  • 1 cup sliced mushrooms
  • 1 cup shredded Swiss cheese plus more for topping
  • 1 cup heavy cream
  • ½ cup chicken broth
  • ½ teaspoon garlic powder
  • 1 teaspoon onion powder
  • to taste salt
  • to taste pepper
  • 2 tablespoons olive oil
  • optional fresh parsley for garnish

Instructions
 

  • Preheat your oven to 350°F (175°C).
  • In a skillet, heat olive oil over medium heat. Add the chicken breasts and season with salt, pepper, garlic powder, and onion powder. Sear the chicken for about 5-7 minutes on each side until browned and cooked through. Remove from heat and let cool slightly.
  • While the chicken is cooling, steam or blanch the broccoli florets and mushrooms for about 3-4 minutes until slightly tender. Drain well and set aside.
  • Once the chicken is cooled, cut it into bite-sized pieces and place it into a large mixing bowl. Add the steamed broccoli, mushrooms, shredded Swiss cheese, heavy cream, and chicken broth. Mix everything well until all ingredients are evenly coated.
  • Transfer the mixture into a greased 9x13 inch baking dish. Sprinkle additional Swiss cheese on top for an extra cheesy crust.
  • Bake in the preheated oven for 30-35 minutes, or until the casserole is bubbling and the cheese is melted and golden brown.
  • Once cooked, remove from the oven and let it rest for a few minutes. Garnish with fresh parsley if desired before serving.

Notes

If you'd like to add more vegetables, zucchini and bell peppers work well in this casserole.
This dish can be made ahead of time and refrigerated; just increase the baking time if cooking from cold.
For a spicier kick, consider adding red pepper flakes or jalapeños.
