Prep: 15 minCook: 3 hr 30 minTotal: 3 hr 45 minServes: 6
Ingredients
- 1 1/2 lb boneless skinless chicken breasts, cut into 1-inch bite-sized pieces
- 1 tsp garlic powder
- 1 tsp onion powder
- 1/2 tsp dried thyme
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1 cup low-sodium chicken broth
- 1 can (10 1/2 oz) condensed cream of chicken soup
- 4 cups fresh broccoli florets, cut into small pieces
- 2 cups cooked white rice
- 4 oz cream cheese, softened
- 1 1/2 cups sharp cheddar cheese, shredded
- 1/2 cup mozzarella cheese, shredded
Instructions
- Place the cubed chicken breasts into the bottom of the slow cooker insert and season evenly with garlic powder, onion powder, dried thyme, salt, and black pepper.
- Pour the chicken broth and cream of chicken soup over the seasoned chicken, stirring lightly to combine and submerge the chicken.
- Cover and cook on LOW for 3 hours (or HIGH for 1 1/2 hours) until the chicken reaches a safe internal temperature of 165 F.
- Uncover and stir in the softened cream cheese, cooked white rice, and fresh broccoli florets until well incorporated.
- Top evenly with shredded cheddar and mozzarella cheeses. Cover and cook on HIGH for an additional 20 to 30 minutes until the broccoli is tender and the cheese is fully melted and bubbly.
Tips
- For best texture, use fresh broccoli florets rather than frozen to prevent excess moisture in the casserole.
- Store leftover casserole in an airtight container in the refrigerator for up to 3 days and reheat gently in the oven or microwave.
- You can substitute brown rice for white rice, ensuring it is fully cooked before stirring into the crockpot at the end.
