- Preheat Oven:
- Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish with cooking spray or butter.
- Steam Broccoli:
- Steam the fresh broccoli florets until they are just tender. You can steam them in the microwave or on the stovetop. Drain any excess water and set aside.
- Prepare Cheese Mixture:
- In a large mixing bowl, combine the softened cream cheese, sour cream, mayonnaise, minced garlic, onion powder, dried thyme, salt, and pepper. Mix until smooth and well combined.
- Assemble Casserole:
- In the prepared baking dish, spread half of the cooked chicken in an even layer.
- Top the chicken with half of the steamed broccoli florets.
- Spread half of the cheese mixture over the broccoli layer.
- Sprinkle half of the shredded cheddar cheese, shredded mozzarella cheese, and grated Parmesan cheese over the cheese mixture.
- Repeat the layers with the remaining chicken, broccoli, and cheese mixture.
- Bake:
- Cover the casserole dish with aluminum foil and bake in the preheated oven for 20 minutes.
- Remove the foil and continue baking for an additional 10-15 minutes, or until the cheese is melted and bubbly and the casserole is heated through.
