This creamy chicken and rice casserole is the answer to chilly nights and busy days. Packed with tender chicken, fluffy rice, a silky mushroom sauce, and pockets of melty cheese, it is a nostalgic comfort meal that fills the whole kitchen with warmth. I love that you can freeze it right after assembly, making dinner happen on even the most hectic weeknights.
I started making this casserole when my youngest was a toddler and now it has become a cold weather tradition for us. There is nothing better than pulling a homemade dinner right from the freezer after a long workday.
Ingredients
- Cooked chicken: brings protein and turns this into a hearty main dish choose rotisserie or leftover chicken for convenience
- Uncooked rice: barley soaks up all the flavors in the baking process go for long grain for fluffier texture or brown rice for extra nutrition
- Cream of mushroom soup: creates a creamy base opt for low sodium or homemade if you prefer
- Chicken broth: boosts flavor and keeps everything moist quality broth can make a real difference
- Shredded cheddar: adds melty richness use sharp cheddar for more punch or mild for kid appeal

- Diced onions: amp up savory depth chop them evenly so every bite is consistent
- Salt and pepper to taste: fresh cracked pepper brightens the whole dish
Instructions
- Prepare the Casserole Dish:
- Spoon a small amount of chicken broth over the bottom of a freezer safe baking dish and spread lightly this prevents the rice from sticking as it cooks
- Combine the Main Ingredients:
- In a large bowl toss together the cooked chicken uncooked rice cream of mushroom soup remaining chicken broth frozen peas diced onions and a big pinch of salt and pepper Stir really well so every grain of rice is coated and distributed evenly
- Fill the Baking Dish:
- Pour the mixture into your prepared baking dish Use a spatula to spread everything out so the casserole bakes evenly and the rice sits mostly beneath the liquid
- Top with Cheese:
- Sprinkle shredded cheddar in a thick even layer over the entire surface making sure to reach every corner for that golden bubbly finish
- Freeze or Bake:
- Wrap the dish tightly with foil if freezing store flat in your freezer Label with date and baking directions If you plan to bake right away preheat the oven to 375 degrees Fahrenheit and bake uncovered for about one hour to seventy minutes until rice is tender cheese is bubbling and top is golden
- Baking from Frozen:
- Place the frozen casserole in a cold oven set to 375 degrees Fahrenheit Bake covered for about an hour then remove foil for last ten to fifteen minutes to allow cheese to brown Check that rice is cooked through before serving

My favorite part of this recipe is waiting for the cheese to bubble up golden in the oven that scent brings everyone right to the table Even my pickiest eater cannot resist the creamy rice and peas
Storage Tips
