Nothing feels more comforting on a busy weeknight than this Cheesy Broccoli Chicken and Rice Casserole. Packed with tender chicken, gooey cheese, fresh broccoli, and fluffy rice, this classic casserole brings everyone to the table. It is a delicious way to use simple pantry staples and sneak extra veggies onto the plate my family has requested it more times than I can count especially after long days that call for something easy and satisfying.
The first time I made this was during a cold snap when I needed something to fill everyone up and warm our kitchen. It instantly became a favorite and even picky eaters always go back for seconds.
Ingredients
- Chicken breasts: choose boneless skinless and cut them into even cubes for juicy bites and quick cooking
- Onion: finely chopped for a fragrant base choose fresh firm onions with no sprouting
- Garlic: minced for rich aromatic depth opt for fresh cloves over prechopped jarred garlic
- White long grain rice: be sure to rinse until the water runs clear for the best texture avoid sticky rice
- Chicken stock: use a good quality low sodium broth for enhanced flavor without oversalting
- Water: ensures the rice cooks evenly and stays light and fluffy
- Broccoli florets: chop into small pieces for even cooking pick bright green heads that are firm and tight
- Milk: adds creaminess and ties everything together whole or two percent works best
- Sharp cheddar cheese: freshly shredded melts smoother than prebagged and brings tangy richness
Instructions
- Prepare the Chicken:
- Cube the chicken breasts into equal size pieces and season with salt and pepper. Toss well to coat so every bite is flavorful.
- Brown the Chicken:
- Heat olive oil in a large oven safe pan over medium high until hot. Add chicken cubes and brown each side for five to seven minutes. Do not fully cook through just develop a golden crust for flavor.
- Sauté the Onion and Garlic:
- Remove browned chicken to a plate. In the same pan add finely chopped onion and cook for around five minutes stirring often until soft and translucent. Stir in minced garlic and cook just thirty seconds to release the aromatics.
- Combine and Simmer:
- Return browned chicken to the pot. Add rinsed white rice chicken stock and water. Mix everything well and bring to a boil then reduce heat to low cover with a tight fitting lid and cook for ten minutes.
- Add Broccoli:
- After ten minutes stir in chopped broccoli evenly through the rice and chicken. Cover again and continue cooking on low stirring occasionally until the rice is fully tender and most liquid has absorbed.
- Mix in Dairy:
- Preheat your oven to four hundred twent five degrees Fahrenheit. Once the rice is cooked stir in milk to add creaminess. Fold in one cup of shredded cheddar so it melts into the hot casserole.
- Bake with Cheese:
- Sprinkle the remaining cheddar cheese over the top. Place the entire pan in the oven and bake for ten to fifteen minutes until the cheese is melted and bubbling golden around the edges.

I always love the broccoli here. When it cooks into the rice it is almost creamy itself and my kids who were once very suspicious of anything green now look for the bites with the most broccoli. One winter my mom and I made this casserole ahead for a family reunion and even the leftovers were fondly fought over the next day.
Storage Tips
Keep leftovers in an airtight container in the fridge for up to four days. To reheat just microwave individual portions or warm in a covered baking dish at three hundred fifty degrees until hot and bubbly again. I usually add a splash of milk before reheating to keep things creamy.
Ingredient Substitutions
Swap out the chicken for rotisserie pulled chicken to save even more time. You can also use brown rice but extend the cooking time and add a bit more liquid. Cauliflower florets work well in place of broccoli if that is what you have on hand.
Serving Suggestions
This hearty casserole pairs wonderfully with a crisp side salad or some crusty garlic bread. For a little extra zing sprinkle finely chopped green onions or a handful of fresh herbs just before serving. A dollop of sour cream gives a cool creamy finish.
Cultural and Historical Context
This casserole traces back to midcentury comfort cooking when home cooks needed easy meals that stretched ingredients and fed hungry families. The rice and chicken combo has countless variations across cultures but the addition of cheddar brings a cozy American touch.
Seasonal Adaptations
Add diced red bell pepper along with the broccoli for a pop of color. Use leftover roasted turkey in place of chicken after holidays. Try stirring in a handful of thawed green peas or asparagus during spring months.
Success Stories
One reader told me she made this on a Sunday for meal prep and her kids preferred it over takeout all week. Another friend prepared it for a new mom and it was the first homecooked meal she could finish with a newborn in tow.
Freezer Meal Conversion
Assemble everything up to just before baking. Cool completely cover tightly and freeze for up to two months. Thaw overnight in the fridge then bake as directed adding a few splashes of broth if needed to keep it moist.

This casserole is as warm and inviting as a quilt on a cold afternoon and I am sure it will become a staple in your recipe rotation too.
Recipe Q&A
- → How can I make sure the chicken stays juicy?
Brown the chicken pieces briefly and avoid overcooking before baking. They’ll finish cooking in the oven, keeping the texture tender.
- → Can I use brown rice instead of white rice?
Brown rice is possible, but extend the simmering time and add extra liquid to ensure the rice cooks through.
- → What type of cheese works best?
Sharp cheddar adds robust flavor, but other melting cheeses like Monterey Jack or mozzarella can also be used.
- → Can I prepare this dish ahead of time?
Yes, assemble everything except the final cheese topping. Refrigerate, then bake with cheese when ready to serve.
- → How do I avoid mushy broccoli?
Add broccoli midway through cooking so it softens without overcooking, keeping a vibrant color and texture.
- → Are there ways to make this dish vegetarian?
Swap chicken for beans or tofu and use vegetable stock for a hearty meatless alternative.
