Step 2: Prepare the Broccoli
If using fresh broccoli:
Bring a pot of water to a boil and blanch the florets for 2–3 minutes.
Drain well.
If using frozen broccoli:
Thaw completely and drain any excess moisture.
(This helps prevent a watery casserole.)
Step 3: Mix the Alfredo Filling
In a large mixing bowl, combine:
- cooked chicken
- broccoli
- heavy cream
- mozzarella cheese
- Parmesan cheese
- garlic powder
- onion powder
- Italian seasoning
- salt
- black pepper
Mix until everything is evenly coated in creamy goodness.
Step 4: Assemble
Transfer the mixture into your prepared baking dish.
Spread evenly.
For an extra cheesy golden crust, sprinkle additional mozzarella over the top.
Step 5: Bake
Bake uncovered for 25–30 minutes, or until:
- cheese is melted
- top is golden
- sauce is bubbling
Your kitchen will smell absolutely incredible.
Step 6: Rest & Serve
Let the casserole rest for 5 minutes before serving.
Garnish with fresh parsley if desired.
Serve warm and enjoy every creamy bite.
