What Kind of Chicken Works Best?

For ultimate convenience, shredded rotisserie chicken is a game changer. It brings great flavor and saves time. You can also use poached or grilled chicken breast if you prefer a leaner option. Just be sure it’s cooked and shredded or chopped before mixing into the casserole.

Dark meat also works if you want richer flavor—thighs especially stay moist during baking. As long as it’s fully cooked and well-seasoned, any variety will do.

How To Make the Healthier Broccoli Chicken Casserole

Step 1: Prepare the Broccoli

Steam the broccoli florets just until they’re tender-crisp. You can do this in the microwave with a bit of water or on the stovetop. Drain and set aside.

Step 2: Make the Sauce

In a saucepan over medium heat, whisk together the Greek yogurt and milk until warm. Stir in garlic powder, onion powder, salt, and pepper. Once combined, add in half the shredded cheese and stir until melted into a creamy sauce.

Step 3: Combine the Casserole

In a large mixing bowl, combine the cooked chicken, steamed broccoli, and sauce. Stir everything together until well coated.

Step 4: Assemble and Top

Transfer the mixture into a greased baking dish. Sprinkle the remaining cheese over the top, followed by breadcrumbs or crushed crackers. Lightly mist with olive oil spray.

Step 5: Bake

Bake at 375°F for 20 to 25 minutes, or until the top is golden and bubbly. Let it rest for a few minutes before serving.

Serving and Storing Your Casserole

This casserole yields about 6 generous servings, making it perfect for family dinners or weekly meal prep. Serve it hot, straight from the oven, paired with a fresh salad or some crusty bread.

If you have leftovers, they keep beautifully in the fridge for up to 4 days. Just reheat in the microwave or oven. You can also freeze portions for up to 2 months—just thaw overnight and reheat as needed.
