Equipment

  • 1 oven-safe casserole dish
  • 1 skillet
  • 1 cutting board
  • 1 mixing bowl
  • 1 measuring cups and spoons

Ingredients
  

  • 2 lbs boneless, skinless chicken breasts, diced
  • 8 oz mushrooms, sliced
  • 1 cup heavy cream
  • 1 cup shredded cheddar cheese
  • 1 cup broccoli florets optional
  • 1 tablespoon olive oil
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • to taste salt and pepper
  • fresh parsley for garnish optional

Instructions
 

  • Preheat the oven to 350°F (175°C).
  • In a skillet, heat olive oil over medium heat. Add the diced chicken and season with salt, pepper, garlic powder, and onion powder. Cook for about 5-7 minutes, or until the chicken is no longer pink. Remove from heat.
  • In the same skillet, add the sliced mushrooms and cook until they are soft and their moisture has reduced, about 5 minutes.
  • In a mixing bowl, combine the cooked chicken, mushrooms, heavy cream, and half of the shredded cheddar cheese. Stir until well combined. If using broccoli, mix it in as well.
  • Transfer the mixture into an oven-safe casserole dish, spreading it evenly. Top with the remaining cheddar cheese.
  • Bake in the preheated oven for 25-30 minutes, or until the cheese is melted and bubbly.
  • Remove from the oven and let it cool for a few minutes. Garnish with fresh parsley if desired before serving.

Notes

Feel free to add other low-carb vegetables such as spinach or zucchini for extra nutrition.
This casserole can be stored in the refrigerator for up to 3 days.
If you like a crunchier topping, consider adding some crushed pork rinds or grated Parmesan cheese on top before baking.
