Some dinners just wrap you up like a favorite blanket, and this casserole does exactly that. It’s the kind of meal that feels like home the moment you pull it out of the oven, with the smell of garlic and mushrooms weaving through the air. I remember one evening, distracted by a phone call, I almost left the casserole in the oven a few minutes too long—but that golden cheese crust was worth the extra wait. The broccoli stays just crisp enough, nestled among the creamy rice and tender chicken, making every bite feel like a small celebration of simple ingredients coming together.
Why You’ll Love It:
- It’s cozy and creamy without being fussy — sometimes simple is exactly what you need.
- Combines protein, veggies, and starch in one dish, cutting down on cleanup and stress.
- The subtle herbs and spices add just enough flavor without overpowering the comforting mushroom base.
- It’s forgiving — a little overcooked or under-seasoned here and there won’t ruin the whole dish.
If you’re new to casseroles or hesitant about combining so many ingredients, this one is a gentle introduction that rarely fails to please—even if you forget a step or two.

Chicken Broccoli Rice Cream of Mushroom Casserole
- Total Time: 1 hour
- Yield: 6
Description
A comforting and creamy casserole combining tender chicken, broccoli, rice, and cream of mushroom soup, perfect for an easy weeknight dinner.
Ingredients
2 cups cooked white rice
2 cups cooked chicken breast, shredded
3 cups fresh broccoli florets
1 can (10.5 ounces) cream of mushroom soup
1 cup sour cream
1 cup shredded cheddar cheese
1/2 cup milk
1/2 cup chopped onion
2 cloves garlic, minced
1 tablespoon olive oil
1/2 teaspoon salt
1/4 teaspoon black pepper
1/4 teaspoon dried thyme
1/4 teaspoon paprika
1/2 cup shredded mozzarella cheese
Instructions
Preheat the oven to 350°F (175°C).
Steam the broccoli florets until tender but still crisp, about 4-5 minutes. Drain and set aside.
In a medium skillet, heat olive oil over medium heat. Add chopped onion and minced garlic, sautéing until softened and fragrant, about 3-4 minutes.
In a large mixing bowl, combine the cooked rice, shredded chicken, steamed broccoli, sautéed onion and garlic, cream of mushroom soup, sour cream, milk, shredded cheddar cheese, salt, black pepper, dried thyme, and paprika. Mix well until all ingredients are evenly incorporated.
Transfer the mixture into a greased 9×13 inch casserole dish and spread evenly.
Sprinkle shredded mozzarella cheese evenly over the top of the casserole.
Bake in the preheated oven for 35-40 minutes, or until the casserole is bubbly and the cheese on top is melted and lightly golden.
Remove from the oven and let it rest for 5 minutes before serving.

Kitchen Notes: This casserole comes together easily in a standard baking dish—no special equipment needed beyond a skillet for sautéing the aromatics. I usually serve it with a simple side salad or some crusty bread to balance the richness. Sometimes, I swap out the cheddar for a sharper cheese or add a sprinkle of crushed red pepper flakes if I’m feeling adventurous, though the original is pretty satisfying on its own. Also, if you want to sneak in more veggies, cauliflower or mushrooms can slide in without much fuss, but I haven’t tested these swaps extensively.
FAQ:
Can I prepare this ahead of time? Absolutely, assembling it the day before and baking when ready actually lets the flavors meld beautifully.
Is it freezer-friendly? Yes, it freezes well for up to three months; just thaw overnight in the fridge before reheating.
What if I don’t have cream of mushroom soup? You can make a quick homemade version with mushrooms, milk, and a roux, but the canned soup is definitely the time-saver here.
