How to Serve Chicken Broccoli Rice Casserole

How to Store Chicken Broccoli Rice Casserole
To store any leftover casserole, let it cool completely and then place it in an airtight container in the refrigerator. It should be good for 3 to 4 days. If you want to keep it longer, you can freeze it. Just cover it tightly and it can last for up to 2 months in the freezer. To reheat, thaw it overnight in the fridge and bake until hot.
Tips to Make Chicken Broccoli Rice Casserole
- Make sure your broccoli is cooked but still slightly crisp. This will prevent it from getting too soft in the oven.
- You can use leftover cooked chicken or a store-bought rotisserie chicken to save time.
- If you want a little extra crunch, top the casserole with crushed crackers or chips instead of breadcrumbs.
Variation
You can easily change the vegetables in this casserole. Try adding bell peppers, carrots, or even spinach for different flavors and textures. You can also experiment with different cheeses like pepper jack for a bit of spice.
