Ingredients

Directions

1. Preheat the Oven

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or nonstick cooking spray.

2. Prepare the Casserole

In a large mixing bowl, combine the cooked chicken, steamed broccoli, cooked rice, and 1 cup of the shredded cheddar cheese.

3. Make the Creamy Sauce

In a separate bowl, whisk together the mayonnaise, sour cream, chicken broth, Parmesan cheese, minced garlic, dried thyme, salt, and black pepper until smooth and well combined.

4. Combine Everything

Pour the sauce over the chicken mixture and stir until all of the ingredients are evenly coated.

5. Assemble

Spread the mixture evenly into the prepared baking dish. Sprinkle the remaining ½ cup shredded cheddar cheese over the top.

6. Bake

Bake uncovered for 25–30 minutes, or until the casserole is hot, bubbly, and the cheese is melted and lightly golden.

7. Rest and Serve

Let the casserole rest for 5–10 minutes before serving. Garnish with a little chopped parsley if desired, then serve warm and enjoy!

RECIPE TIPS

● For the creamiest casserole, don't overcook the broccoli before baking—it will continue to cook in the oven. Freshly shred your own cheddar cheese for the smoothest melt, and let the casserole rest for 5–10 minutes after baking so it sets up beautifully and is easier to serve.

Frequently Asked Questions

Can I use rotisserie chicken?
Absolutely! Rotisserie chicken is a great time-saver and adds plenty of flavor to this casserole.
Can I use frozen broccoli?
Yes. Thaw and drain the broccoli well before adding it to the casserole to prevent excess moisture.
Can I make this casserole ahead of time?
Yes! Assemble the casserole up to 24 hours in advance, cover tightly, and refrigerate. Bake just before serving, adding an extra 5–10 minutes if it's coming straight from the refrigerator.
Can I use a different cheese?
Definitely. Colby Jack, Monterey Jack, mozzarella, or a cheddar blend all work well in this recipe.
Can I freeze Chicken Broccoli Rice Casserole?
Yes. Let the casserole cool completely, wrap it tightly, and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating for the best texture.
