Making Lunch Lady Broccoli Cheese & Rice Casserole is straightforward when you follow these clear steps:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C).
2. Prepare the Broccoli: If using fresh broccoli, steam or blanch the florets for about 2-3 minutes until they are tender but still bright green. If using frozen broccoli, ensure it’s thawed and drained.
3. Mix the Base: In a large mixing bowl, combine the cooked rice, steamed broccoli, cream of mushroom soup, milk, garlic powder, onion powder, and shredded cheddar cheese. Stir until well combined.
4. Season: Add salt and pepper according to taste, mixing thoroughly.
5. Transfer to Casserole Dish: Pour the mixture into a greased 9×13-inch casserole dish, spreading it evenly.
6. Prepare the Topping: In a small bowl, combine the breadcrumbs with melted butter, stirring to coat evenly. This will create a delicious, crispy topping for the casserole.
7. Add the Topping: Sprinkle the breadcrumb mixture over the top of the casserole.
8. Bake: Place the casserole in the preheated oven and bake for 35-40 minutes or until the cheese is melted and the top is golden brown.
9. Cool and Serve: Once out of the oven, allow it to cool for a few minutes before serving.

These steps will ensure your casserole turns out delightfully creamy and cheesy with a satisfying crunch on top.
