Preparation Steps for Broccoli Chicken Casserole

Preparation Steps for Broccoli Chicken Casserole
1

Warm Up the Oven

Set your oven to 375F. Grab a 9×13-inch baking dish and give it a quick spray of cooking oil so nothing sticks.

2

Prepare the Broccoli

If you’re using fresh broccoli, drop those green florets into boiling water for exactly 2 minutes. Then quickly drain and splash with cold water to stop the cooking. Frozen broccoli? Just make sure it’s thawed completely.

3

Create the Creamy Base

Grab a big mixing bowl and whip together these ingredients into a smooth sauce:

  • 1 cup Greek yogurt
  • 1/2 cup low-sodium chicken broth
  • 1 teaspoon Dijon mustard
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon paprika

Whisk everything until it looks super smooth and creamy.

4

Build the Casserole Base

Toss these ingredients right into your prepared baking dish:

  • 2 cups cooked chicken breast
  • 3 cups broccoli florets
  • 1 1/2 cups cooked brown rice

Stir everything around to get a good mix.

5

Pour and Spread the Sauce

Pour your creamy sauce over the chicken and broccoli. Gently stir to make sure everything gets coated.

6

Add the Cheesy Topping

Sprinkle these ingredients across the top:

  • 1 cup shredded cheddar cheese

In a separate small bowl, mix:

  • 1/2 cup whole wheat breadcrumbs
  • 1/4 cup Parmesan cheese
  • 1 teaspoon olive oil

Scatter this mixture over the cheese for a crispy finish.

7

Bake to Golden Perfection

Slide the dish into your preheated oven. Bake for 20-25 minutes until the cheese melts and the top turns a beautiful golden brown.

8

Rest and Serve

Pull the casserole out and let it sit for 5 minutes. This helps everything settle and makes serving easier. Grab a serving spoon and dig in while it’s warm!
