Cheesy Broccoli Chicken and Rice Casserole is creamy comfort food at its best and a true weeknight lifesaver. This one-pot wonder brings together juicy chicken breast, tender broccoli, fluffy rice, and a generous layer of cheddar cheese for a dish everyone wants second helpings of. I reach for it anytime I want a meal that tastes like a warm hug and leaves barely any dishes behind.
I remember the first time I made this casserole for a family gathering and everyone went back for more. Now it has become our go-to dish for busy evenings when we all want something comforting and satisfying.
Ingredients
- Chicken breast cubes: provide lean protein and stay juicy if browned first. Choose firm pink fillets without a strong smell for the freshest flavor
- Onion: delivers sweetness and depth. Pick a small yellow or white onion for the best base
- Garlic: adds aroma and savory warmth. Fresh cloves are best
- Long grain white rice: becomes fluffy and soaks up all the flavors. Rinse well to remove extra starch for the best texture
- Chicken stock: gives a savory backbone to the dish. Choose low sodium and high quality for better control of salt
- Water: helps cook the rice evenly without making it too salty
- Broccoli florets: bring color and a fresh bite. Look for bright green florets with no yellowing
- Milk: creates a creamy consistency. Whole or two percent both work
- Sharp cheddar cheese: melts beautifully and adds tangy richness. Shred your own from a block for the smoothest results
Step-by-Step Instructions
- Prep the Chicken:
- Cube the chicken breasts into even 1 inch pieces and season with salt and pepper. This helps every piece cook evenly and taste great
- Brown the Chicken:
- Heat a sturdy pan over medium high and add a little olive oil. Place the chicken pieces in and let them sit without moving for about three minutes before flipping. Brown all sides for rich flavor but do not worry about cooking the chicken through right now
- Soften Aromatics:
- Transfer browned chicken to a plate. Add chopped onion to the pan and sauté for about five minutes until translucent and tender. Stir in the minced garlic and cook for thirty seconds until it smells fragrant
- Combine and Simmer:
- Return chicken to the pan along with rinsed rice chicken stock and water. Stir well then bring to a boil. Cover the pan turn the heat low and simmer for ten minutes
- Add Broccoli and Cook:
- Lift the lid and stir in the chopped broccoli. Replace the lid and continue simmering just until rice is fully cooked and everything is tender. Stir from time to time to prevent sticking
- Finish with Cheese:
- Once the rice is done stir in the milk. Add one cup shredded cheddar and fold gently until melted and creamy
- Broil the Top:
- Sprinkle the remaining cheese on top. Move the pan to a preheated oven at four hundred twenty five degrees Fahrenheit. Bake ten to fifteen minutes until the cheese is bubbling and golden

My favorite part is how the cheese forms a salty crispy top layer that everyone fights for. Watching my family sneak crunchy edges from the casserole dish is a tradition in my house and makes this meal extra special.
Storage Tips
Let the casserole cool fully then transfer it to an airtight container before placing in the fridge. It stays fresh for about two days and you can reheat single portions in the microwave or warm the whole dish in the oven. If you need to prepare ahead leave off the last cheese topping until right before baking and serving
Ingredient Substitutions
Feel free to swap in boneless thigh meat for the chicken if you want extra richness. You can use Arborio rice for a creamier consistency or stick to Basmati for long fluffy grains. If you use frozen broccoli remember to thaw it well and drain off any liquid so the casserole does not get soggy. For dairy free you can use your favorite plant based milk plus a dairy free cheese
Serving Suggestions
Pair this casserole with a crisp green salad or simply add a handful of cherry tomatoes on the side for freshness. For bigger appetites offer warm bread rolls to mop up any cheesy sauce left on the plate
Cultural Note
These sorts of casseroles are a true American comfort food tradition dating back to the popularity of one dish dinners in the twentieth century. They are loved for their convenience and ability to feed a family on a budget with familiar flavors
