Ingredients
  

  • 2 cups Boneless skinless chicken breasts, cooked and diced Rotisserie chicken works great as a shortcut
  • 3 cups Cooked white rice
  • 3 cups Broccoli florets Steamed until just tender
  • 2 tbsp Butter
  • 1/2 cup Onion, chopped
  • 2 cloves Garlic, minced
  • 2 tbsp All-purpose flour
  • 1.5 cups Chicken broth
  • 1/2 cup Milk Whole or 2% works best
  • 2 cups Sharp cheddar cheese, freshly grated Divided use
  • 1/2 tsp Salt
  • 1/4 tsp Black pepper

Instructions
 

  • Preheat your oven to 375°F (190°C) and lightly grease a 9x13 inch baking dish.
  • In a large skillet, melt the butter over medium heat. Add the chopped onion and cook until translucent, about 4 minutes. Add the minced garlic and cook for 1 more minute.
  • Sprinkle the flour over the onions and garlic, stirring constantly for 1 minute to cook the raw flour taste.
  • Gradually whisk in the chicken broth and milk until the mixture is smooth. Bring to a gentle simmer and cook until slightly thickened, about 3-5 minutes.
  • Remove the skillet from the heat. Stir in 1.5 cups of the grated cheddar cheese, salt, and black pepper until the cheese is completely melted and the sauce is smooth.
  • In a large mixing bowl, combine the cooked diced chicken, cooked rice, and broccoli florets. Pour the cheese sauce over the mixture and gently toss to coat everything evenly.
  • Transfer the mixture to the prepared baking dish and spread it out into an even layer. Top with the remaining 1/2 cup of cheddar cheese.
  • Bake uncovered for 25-30 minutes, or until the casserole is bubbly and the cheese is lightly golden on top. Let rest for 5 minutes before serving.
