Step‑by‑Step Instructions for Cheesy Broccoli Chicken and Rice Casserole
Step 1: Prepare the Chicken
Start by cutting chicken breasts into 1×1-inch cubes, ensuring they cook evenly. Season the chicken pieces with salt and pepper. Heat a tablespoon of oil in a heavy-bottomed skillet over medium-high heat, then add the chicken. Sear for 5-7 minutes until the chicken is browned on all sides. Remove the chicken from the pan and set aside to keep it juicy.
Step 2: Sauté the Aromatics
In the same skillet, add the finely chopped onion and sauté for 3-4 minutes until it becomes translucent and fragrant. Next, add the minced garlic and cook for an additional 30 seconds, stirring constantly to prevent burning. This step enhances the flavor base for your Cheesy Broccoli Chicken and Rice Casserole, creating an aromatic foundation.
Step 3: Combine Ingredients
Return the browned chicken to the skillet and incorporate the rinsed long-grain rice. Pour in the chicken stock and water, stirring everything together. Increase the heat to bring the mixture to a boil, then reduce to low heat. Cover the skillet and let it simmer for 10 minutes, allowing the rice to absorb the flavors and moisture.
Step 4: Add the Broccoli
After 10 minutes, lift the lid and stir in the roughly chopped broccoli florets. Quickly cover the skillet again and let it cook for an additional 5-7 minutes. You’ll know it’s ready when the broccoli is tender but still vibrant in color and the rice is fully cooked, making your Cheesy Broccoli Chicken and Rice Casserole luscious and colorful.
Step 5: Preheat the Oven
While the broccoli and rice finish cooking, preheat your oven to 425°F (220°C). This ensures the oven is hot enough to melt the cheese perfectly in the next step, giving your casserole that golden, bubbling top that everyone loves.
Step 6: Stir in Creaminess
Remove the skillet from heat. Stir in the milk and one cup of shredded sharp cheddar cheese, mixing well until fully melted and combined. The creamy texture forms as you do this, making your Cheesy Broccoli Chicken and Rice Casserole rich and mouthwatering.
Step 7: Bake Until Golden
Transfer the mixture to a greased baking dish and top it evenly with the remaining shredded cheddar cheese. Place the dish in the preheated oven and bake for 10-15 minutes, or until the cheese is melted and bubbling, creating a deliciously gooey, cheesy crust that is simply irresistible.

Cheesy Broccoli Chicken and Rice Casserole Recipe FAQs
What type of broccoli should I use for this casserole?
Absolutely! Fresh broccoli florets are ideal for this recipe; they bring a vibrant color and a crunchy texture that complements the creamy cheese. If fresh isn’t available, you can use frozen broccoli. Just be sure to thaw and drain any excess water before adding it to the casserole to prevent sogginess.
How long can I store leftovers of the Cheesy Broccoli Chicken and Rice Casserole?
Leftover casserole can be kept in the fridge in an airtight container for up to 2 days. Make sure to let it cool down completely before sealing to help maintain freshness. If you want to save it longer, you can freeze it!
Can I freeze the casserole if I have leftovers?
Very! To freeze, place the cooled casserole in a sealed, freezer-safe container. It will keep well in the freezer for up to 3 months. I often recommend portioning it into smaller containers; this way, you can easily reheat just what you need without thawing the entire dish.
What if my rice isn’t cooking properly?
If your rice is undercooked or too hard, double-check the liquid ratio. Using long-grain rice generally requires 2 cups of liquid for every cup of rice. If you used brown rice, increase the simmering time slightly to about 15-20 minutes. Always make sure to cover the pot tightly while cooking to trap steam; this is key for cooking that tender rice!
Is this casserole okay for people with gluten allergies?
Yes, it can be made gluten-free! Just ensure you use gluten-free chicken stock and check your rice package for any gluten-free labeling. Substituting the milk with a non-dairy option can also make it suitable for those with lactose intolerance or dairy allergies.
Can I make the casserole ahead of time?
Absolutely! You can prepare the Cheesy Broccoli Chicken and Rice Casserole in advance. Assemble it without the cheese topping and cover it tightly in the refrigerator for up to a day. When you’re ready to serve, just add the cheese and bake as directed for a quick and easy weeknight dinner!
