It’s perfect for busy weeknights or meal prepping, offering a hearty dish that’s both satisfying and versatile.

Ingredients

3 cups cooked chicken, shredded or diced (about 1.5 pounds cooked chicken)
2 cups cooked rice (white or brown)
1 can (10.5 oz) cream of mushroom soup
1 can (10.5 oz) cream of chicken soup
1 cup sour cream
1 cup shredded cheddar cheese
1 small onion, finely chopped
2 cloves garlic, minced
1 cup frozen peas (thawed)
1/2 teaspoon black pepper
1/2 teaspoon salt (adjust to taste)
1/2 teaspoon paprika (optional, for flavor)
2 tablespoons olive oil or butter
1/2 cup grated Parmesan cheese (optional, for topping)

Instructions

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or non-stick spray.

In a large skillet, heat the olive oil or butter over medium heat. Add the chopped onion and minced garlic, sautéing until translucent and fragrant, about 3-4 minutes.
Add the cooked chicken to the skillet to warm through, then remove from heat.
In a large mixing bowl, combine the cream of mushroom soup, cream of chicken soup, and sour cream. Mix until smooth.

Add the cooked rice, sautéed onions and garlic, shredded chicken, thawed peas, salt, pepper, and paprika to the bowl. Stir well to combine all ingredients evenly.
Transfer the mixture into the prepared 9×13 dish, spreading it out evenly with a spatula.
Sprinkle the shredded cheddar cheese evenly over the top of the casserole. If using, sprinkle Parmesan cheese for extra flavor.

Bake in the preheated oven for 25-30 minutes, or until the casserole is bubbling and the cheese has melted and turned slightly golden.
Remove from oven and let sit for 5 minutes before serving. This helps the casserole set and makes it easier to serve clean slices.

Tips

Substitutions: Use cooked turkey or chicken thighs instead of chicken breast for a richer flavor. Swap out rice for cooked quinoa or cauliflower rice for a low-carb version.

Make ahead: Prepare the casserole mixture a day in advance, cover tightly, and refrigerate. Bake it straight from the fridge, adding an extra 10 minutes to the baking time.
Prevent drying out: Cover the casserole with foil during the first 20 minutes of baking if you’re worried about it drying out, then remove for the last 5-10 minutes to brown the cheese.
Common mistake: Not draining excess liquids from the cooked chicken or rice can make the casserole watery. Ensure ingredients are well-drained before mixing.

Serving Suggestions

This hearty chicken casserole pairs wonderfully with a crisp green salad or steamed vegetables like broccoli or green beans. You can also serve it with crusty bread or garlic bread for a more filling meal. For a lighter option, serve smaller portions alongside a side of fresh fruit.

Variations

Vegetable boost: Add diced carrots, bell peppers, or mushrooms to the sautéing step for more vegetable nutrition and flavor.
Spicy version: Incorporate a dash of hot sauce or diced jalapeños into the mixture for a spicy kick.

Cheese options: Experiment with different cheeses like mozzarella, Monterey Jack, or pepper jack for varied flavor profiles.
Low-fat adaptation: Use light sour cream and reduced-fat cheese to make a healthier version.

Storage and Reheating

Leftover chicken casserole can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, microwave individual portions for 2-3 minutes or bake at 350°F (175°C) for 15-20 minutes until heated through. If reheating from frozen, allow it to thaw overnight in the fridge and then reheat thoroughly. The casserole remains good for up to 2 months if frozen properly.
