Ingredients

This is just a quick overview of the simple ingredients that you'll need for an old fashioned Chicken Broccoli and Rice Casserole. As always, specific measurements and complete cooking instructions are included in the printable recipe box at the bottom of the post.

Broccoli: I use fresh broccoli florets here, but you can substitute with frozen broccoli instead. See my notes below for that swap. Cauliflower florets will also work!
Butter: to sauté the vegetables.
Onion, celery, and garlic: savory aromatics that create a flavorful base for the casserole. If you don't have fresh garlic, you can add a little bit of garlic powder to the sauce instead.
Condensed cream of mushroom soup: substitute with other flavors of condensed soup if you prefer. Other good options include cream of chicken soup or cream of celery soup.
Mayonnaise: adds creamy texture and rich flavor to the sauce.
Paprika, dry mustard, and ground nutmeg: additional seasonings that give the dish a flavor boost.
Sharp cheddar cheese: if possible, grate the cheese by hand so that it melts smoother into the dish.
Milk: to thin the creamy sauce. You can also use chicken broth.
Rice: I prefer long-grain white rice in this casserole, but any variety of cooked rice will work.
Chicken: you'll need cooked, shredded chicken, so pickup a store-bought rotisserie chicken for a shortcut, or cook your own chicken at home.
Kosher salt and ground black pepper: season the filling to taste.
Ritz crackers: lightly crushed for a buttery, crunchy topping.

Can you put uncooked chicken in a casserole?

While it's possible to cook a casserole with raw chicken, you'll need cooked chicken for this recipe, and a variety of options will work. Pick the most convenient method for you:

Boiled and Pulled Chicken: Boil about 1 lb. of boneless skinless chicken breasts or thighs until cooked through (about 15 minutes). When cool enough to handle, chop or pull the chicken into bite size pieces. You'll need a total of about 2 cups shredded. I find that 1 lb. of raw chicken breasts yields about 2 cups of pulled chicken, but there's some flexibility here -- it doesn't need to be exact.
Rotisserie Chicken: This is a great shortcut! Purchase a rotisserie chicken from the grocery store, shred the meat, and use in the recipe as instructed. One large rotisserie chicken should yield about 3-4 cups of meat, so you might have some extra to use in a different dish.
Leftover Chicken: If you have leftover grilled or baked chicken from a previous meal, put those extras to good use in this casserole.
Canned Chicken: Yep, you can even use canned chicken in this casserole.

Do I cook the rice before adding it to the casserole?

Yes! This recipe calls for 2 cups of cooked long-grain white rice. You can boil your own rice on the stovetop, use leftovers from a previous meal, or cook parboiled rice (such as Uncle Ben's Ready Rice) in the microwave for a shortcut. If using the microwaveable rice or Minute Rice, cook the rice according to the package instructions before using it in this casserole.

Do you have to cook broccoli before putting it in a casserole?

Yes, if you're starting with fresh broccoli florets as called for in this recipe, you'll need to pre-cook the broccoli slightly before adding it to the casserole. This way it will be nice and tender by the time the casserole heats through. For a shortcut, you can use thawed frozen baby broccoli florets, which are soft enough when thawed so that you don't need to steam or pre-cook them before just adding them to the dish. The baby florets are also small enough that you don't need to chop them. Just thaw, drain, and stir into the casserole!

How to Make Chicken Broccoli and Rice Casserole

While we love a made-from-scratch chicken casserole, there are many busy nights when we just need quicker, easier solutions. That's where this dish comes in! Thanks to help from a handful of store-bought shortcuts like condensed cream of mushroom soup and rotisserie chicken, the casserole comes together in about 20 minutes.

Parboil the broccoli florets just until crisp-tender, about 2 minutes. You can also do this by steaming the broccoli in the microwave for 2-3 minutes, if you prefer.
Sauté onion, celery and garlic in butter.
Reduce the heat to low, and stir in the condensed soup, mayonnaise, cheese, milk and seasoning.
Whisk or stir until the cheese melts, about 2 minutes.
Add the rice, chicken, and broccoli to the creamy sauce mixture. Taste and season with salt and pepper.
Transfer to a greased 2-quart baking dish.
Top with additional cheese and crushed crackers.
Bake, uncovered, in a 350°F oven for about 25 minutes, or until the filling is hot and bubbly and the topping is lightly browned.

What to Serve with Broccoli Rice Cheese and Chicken Casserole

This classic chicken casserole goes well with just about any of your favorite sides. Here are a few easy options to try:

Preparation and Storage

This is a great make-ahead dinner. You can assemble the casserole up to 24 hours in advance and keep it covered in the refrigerator until ready to bake. When ready to bake, allow the dish to sit on the counter and come to room temperature for at least 30-60 minutes.
You can freeze the casserole before baking. Wrapped tightly, the assembled casserole will keep in the freezer for up to 2 months.
Leftover chicken casserole will keep in the refrigerator for 3-4 days.
How to Reheat: If reheating an entire casserole, cover the dish loosely with foil and bake in a 350°F oven until warmed through (about 20-30 minutes). Individual portions can be reheated in the microwave for 1-2 minutes.

Recipe Variations for Chicken Broccoli Rice Casserole

Swap out the fresh broccoli florets for frozen baby broccoli florets. The frozen baby florets are soft enough when thawed so that you don't need to steam or pre-cook them before just adding them to the dish. The baby florets are also small enough that you don't need to chop them. Just thaw, drain, and stir into the casserole!
Instead of cream of mushroom soup, try a different flavor of condensed soup.
Don't have Ritz crackers? Substitute with crushed potato chips, crushed Corn Flakes cereal mixed with melted butter, or other buttery crackers (like Keebler Club crackers). You can also use buttered panko bread crumbs for a crispy topping.
Instead of the broccoli, add frozen peas, corn, steamed green beans or asparagus, or sautéed mushrooms to the casserole.
Try other types of cheese instead of cheddar. Good options include Monterey Jack, Pepper Jack, Colby, Colby Jack, Swiss and American.
Any variety of cooked rice will work. I like long-grain white rice, but a short grain rice, basmati rice, wild rice, or brown rice are fine, too. Just make sure that your rice is cooked before adding it to the casserole.
To serve a larger group, double all of the ingredients and bake the casserole in a deep 9 x 13-inch casserole dish.

Tips for the Best Chicken Broccoli and Rice Casserole Recipe

If you don't want to bother with parboiling the broccoli on the stovetop, you can steam the broccoli florets in the microwave for about 2-3 minutes on high.
Use an oven-proof skillet to sauté the vegetables, and then just bake the casserole in the same pan. This eliminates washing an extra dish!
Quick prep: to help this casserole come together quickly and easily, use store-bought rotisserie chicken, baby broccoli florets that you just have to thaw (no cooking or chopping), and microwaveable packets of rice.
Bake the casserole just until it's heated through. All of the ingredients are already cooked, so you just want to warm it in the oven until bubbly. Don't bake it for too long or it will dry out and the rice will get mushy. You know a casserole is done when the filling is hot and bubbly and the topping is toasted and golden brown.
Garnish with fresh parsley, chives, or other herbs for a bright, colorful touch at the end.
