Ingredients for Chicken Broccoli Rice Casserole

Gather these ingredients before you start. Quantities below are for a standard 9×13-inch casserole serving about 6.

• 2 cups cooked chicken, shredded or diced
• 2 cups cooked rice (white or brown)
• 2 cups broccoli florets, steamed until just tender
• 1 cup cheddar cheese, shredded
• 1/2 cup sour cream
• 1/2 cup mayonnaise
• 1/2 cup milk (use dairy or a non-dairy alternative)
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1/2 teaspoon black pepper
• Salt, to taste
• 1/2 cup breadcrumbs (optional for a crunchy topping)

Notes: You can swap sour cream for Greek yogurt for a tangier, lighter option. For dairy-free diets, use dairy-free mayonnaise, yogurt substitute, and plant milk.

How to Make Chicken Broccoli Rice Casserole – Step by Step

Step 1: Prepare Ingredients

Cook the rice and chicken if they aren’t already prepared. Leftover or rotisserie chicken works well and speeds up prep. Steam broccoli florets until tender but still bright green. Preheat your oven to 350°F (175°C).

Step 2: Mix the Creamy Sauce

In a medium bowl, whisk together the sour cream, mayonnaise, milk, garlic powder, onion powder, black pepper, and salt until smooth. This creates the rich, creamy base that binds the casserole.

Step 3: Combine the Ingredients

In a large bowl, combine the shredded chicken, cooked rice, steamed broccoli, and most of the shredded cheddar (reserve a bit for the top). Pour the sauce over the mixture and stir gently until everything is evenly coated.

Step 4: Assemble in a Baking Dish

Transfer the mixture into a greased 9×13-inch baking dish and spread it evenly. Sprinkle the remaining cheese on top, and if you want a crunchy finish, sprinkle breadcrumbs over the cheese.

Step 5: Bake

Bake in the preheated oven for 25–30 minutes, until the casserole is hot and bubbly and the cheese on top is melted and lightly golden. If using breadcrumbs, you can broil for 1–2 minutes at the end to crisp them — watch closely to avoid burning.

Helpful Tips for the Best Result

• Use freshly shredded cheese rather than pre-shredded for a creamier melt.
• For a little heat, add a pinch of red pepper flakes to the sauce.
• Save time by using precooked or rotisserie chicken.
• Add extra vegetables such as sautéed mushrooms, bell peppers, or peas to boost flavor and nutrition.
• If the casserole seems dry before baking, stir in a few tablespoons more milk.

Cooking Tips

• Best dish: A 9×13-inch baking dish gives even cooking and the right depth for this recipe.
• Crispier topping: Mix the breadcrumbs with a tablespoon of melted butter or a little olive oil before sprinkling on top to help them turn golden.
• Flavor boost: Stir a tablespoon of grated Parmesan into the cheese for extra savory depth.

Serving Suggestions

This casserole pairs nicely with a crisp green salad, roasted vegetables, or a basket of warm crusty bread. For beverages, a light white wine or iced tea complements the creamy richness well.
