How to Make Chicken & Broccoli Casserole

This easy chicken & broccoli casserole is made in just one skillet and is ready in about 30 minutes. It's packed with broccoli and brown rice, making it a hearty and delicious weeknight meal. Here's how to make it:

Cook the Chicken

We start by cooking bite-size chicken breast and chopped onion in a large high-sided ovenproof skillet. It's important to use a large high-sided ovenproof skillet as it has the capacity to cook the ingredients without overcrowding the pan. Flour is added, then milk is added and brought to a boil for 1 minute. Make sure to stir frequently during this step. The flour helps thicken the casserole and the reduced-fat milk makes it creamy without the added fat.

Cook the Broccoli

To ensure tenderness, the broccoli florets are cooked in the microwave for about 3 minutes. Make sure to drain the broccoli before adding it to the casserole.

Finish the Dish

Stir in the precooked brown rice, shredded Cheddar cheese, dry mustard, garlic powder, salt, pepper and broccoli in the skillet. Using precooked brown rice cuts down on the cooking time. The casserole is sprinkled with crispy fried onions and then baked until golden brown and bubbling at the edges, about 10 minutes. The crispy fried onions give the casserole a boost of flavor and a crunchy topping.

  • 1 tablespoon canola oil

  • 1 ½ pounds boneless, skinless chicken breasts, trimmed and cut into bite-size pieces

  • 1 small onion, finely chopped

  • cup all-purpose flour

  • 4 cups reduced-fat milk

  • 3 cups broccoli florets

  • 2 tablespoons water

  • 2 9-ounce packages precooked brown rice

  • 1 ½ cups shredded reduced-fat sharp Cheddar cheese

  • 1 teaspoon dry mustard

  • ½ teaspoon garlic powder

  • ¾ teaspoon salt

  • ½ teaspoon ground pepper

  • 1 cup prepared crispy fried onions


  1. Preheat oven to 400°F.

  2. Heat oil in a large high-sided ovenproof skillet over medium-high heat. Add chicken and chopped onion; cook, stirring occasionally, until the chicken is no longer pink on the outside, about 7 minutes. Sprinkle the mixture with flour and cook, stirring occasionally, for 1 minute. Add milk to the pan and bring to a boil, stirring frequently. (Be careful, the pan will be very full.) Boil, stirring, for 1 minute.

  3. Meanwhile, place broccoli and water in a microwave-safe container. Cover and microwave on High until the broccoli is tender, about 3 minutes. Drain.

  4. Remove the pan from the heat and carefully stir in rice, cheese, dry mustard, garlic powder, salt, pepper and the broccoli. Sprinkle with crispy onions.

  5. Bake the casserole until bubbling at the edges, about 10 minutes. Let stand for 5 minutes before serving.
