- ½ tsp onion powder

Optional:

Equipment
- 9×13-inch (23×33 cm) casserole dish
- Large skillet or saucepan
- Mixing spoon
Step 1: Preheat the Oven
Preheat oven to 375°F (190°C).
Lightly grease the casserole dish with butter or cooking spray.
Step 2: Prepare the Broccoli
Bring a pot of salted water to a boil.
Add broccoli florets and cook for 2–3 minutes.
Drain immediately and rinse with cold water to stop cooking.
Alternatively, steam for 3–4 minutes.
The broccoli should remain slightly crisp.
Step 3: Make the Creamy Sauce
In a large skillet over medium heat:
- Melt butter.
- Add garlic and cook for 30 seconds until fragrant.
Add:
- Heavy cream
- Cream cheese
Whisk until smooth.
Then stir in:
- Mozzarella
- Parmesan
- Onion powder
- Italian seasoning
- Salt
- Pepper
Cook until the cheeses melt and the sauce becomes smooth and creamy.
Step 4: Combine the Filling
In a large bowl combine:
- Chicken
- Broccoli
- Cream sauce
Mix until everything is evenly coated.
Step 5: Assemble the Casserole
Transfer the mixture to the prepared casserole dish.
Spread evenly.
Top with:
- Cheddar cheese
- Parmesan cheese
Add bacon crumbles if using.
Step 6: Bake
Bake uncovered for 25–30 minutes.
The casserole is ready when:
- Cheese is melted
- Top is golden brown
- Edges are bubbling
For extra browning, broil for 2–3 minutes at the end.
Step 7: Rest
Allow the casserole to rest for 5–10 minutes before serving.
This helps the sauce thicken slightly.
