Method
 

Preheat Oven:
  1. Preheat your oven to 375°F (190°C). Grease your casserole dish lightly.
Sauté Chicken and Aromatics:
  1. In a large skillet over medium heat, sauté diced chicken, onion, and garlic in a bit of oil until the chicken is just starting to brown (about 5–6 minutes). Season lightly with salt and pepper.
Assemble the Casserole:
  1. In a mixing bowl or directly in the casserole dish, combine the sautéed chicken, rice, chicken stock, water, and milk. Stir in 1 cup of shredded cheddar cheese and mix well.
Bake Covered:
  1. Cover the casserole tightly with aluminum foil and bake for 30 minutes.
Add Broccoli and More Cheese:
  1. Carefully remove the foil. Stir in broccoli florets, then sprinkle the remaining 1 cup of cheddar cheese over the top.
Finish Baking:
  1. Return to the oven uncovered and bake for another 15–20 minutes, until rice is tender, broccoli is cooked, and cheese is melted and bubbly.
Serve Hot:
  1. Let it cool for 5 minutes before serving. Sprinkle with extra cheddar or fresh parsley if desired!

Notes

🔁 Variations
Swap the Meat: Use shredded rotisserie chicken for even faster prep.
Add a Crunch: Top with breadcrumbs or crushed Ritz crackers for a crispy topping.
Use Brown Rice: Extend the initial covered bake time by 15–20 minutes and add extra liquid if needed.
🧊 Storage Tips
Fridge: Store leftovers in an airtight container for up to 4 days.
Reheat: Warm individual portions in the microwave or reheat the entire dish in the oven at 350°F.
Freeze: Freeze fully baked casserole in portions for up to 2 months. Thaw overnight before reheating.
❓ Frequently Asked Questions
Can I use frozen broccoli?
Yes! No need to thaw — just stir it in frozen during the last baking step.
Can I cook the chicken from raw in the casserole?
Technically yes, but pre-cooking gives better flavor and ensures even doneness.
What type of cheese works best?
Sharp cheddar melts beautifully and adds a nice tang, but you can also mix in mozzarella or Monterey Jack for extra gooeyness.
