  • 1 lb chicken thighs cut into 1" chunks*
  • 1 tbsp oil
  • 1 large head of broccoli stem removed
  • 1/2 tsp salt
  • 1/2 tsp black pepper
  • 1/2 tsp paprika
  • 1/2 tsp garlic powder
  • 1/2 tsp dried parsley
  • 1 cup chicken broth
  • 1-1/2 cups cheddar cheese grated
  • 1 egg
  • 1/2 cup milk
  • 1/2 large yellow onion chopped
  • 4 slices light bread I used artisan
  • 2 tbsp butter softened
  • 1/4 cup breadcrumbs*



  • Cut your sliced bread into 1/2" chunks and cook in a toaster oven until lightly toasted.
  • Heat 1 tbsp oil in a large skillet over medium heat. Add the chicken and broccoli florets to the hot skillet along with salt and pepper. Cover and cook for 7 minutes. Remove lid and stir. Add chopped onion, paprika, garlic powder, parsley and stir to combine. Cook for another 7 minutes, covered. When done, veggies will be tender and chicken will be cooked through.
  • Preheat the oven to 375 degrees.
  • Assemble the casserole, using a 13"x9" baking dish, add the cooked broccoli and chicken mixture evenly into the bottom of baking dish. Scatter the toasted bread on top along with 3/4 cup cheddar cheese. Lightly mix to combine.
  • In a small bowl, whisk together egg, milk and chicken broth. Evenly pour on top of the casserole.
  • In another bowl, mix softened butter with 1/4 cup breadcrumbs and 3/4 cup cheddar cheese. Sprinkle evenly on top the casserole.
  • Cover the casserole with foil and place in the preheated oven for 15 minutes. Remove foil and bake for 10 more minutes. Remove from the oven and let cool for 5 minutes. Enjoy!
