Recipe Variations

Like most casserole dishes, this one easily lends itself to plenty of variations. Here are some ideas.

Broth: For more flavor, you could use chicken broth instead of water.

Soup: Substitute cream of celery soup or cream of chicken soup for the cream of mushroom soup (or mix them together).

Herbs: For additional flavor, consider adding fresh thyme, parsley, paprika, or freshly minced garlic. You could also choose to garnish with fresh basil.

Rotisserie Chicken Casserole: To make things even easier, you can forgo cooking chicken in favor of adding shredded rotisserie chicken.

Chicken and Broccoli Casserole: Add fresh or frozen broccoli florets for a pop of color and flavor. You could also go with peas, green beans, or mixed vegetables.

Chicken and Cheese Casserole: Amp up the creaminess factor with some shredded Cheddar cheese. If you’re in the mood to turn up the heat, pepper jack is a good choice. Other good options are mozzarella, provolone, or Swiss.

How to Serve Chicken and Rice Casserole

Since you’ve got your meat and grains covered, a Caesar salad would be a great choice, or a vegetable side dish such as:

How to Store Leftover Chicken and Rice Casserole

Refrigerator: Store leftovers in an airtight container in the fridge for up to 4 days.

Reheating: It’s important to thoroughly reheat any dish containing rice, as leftover rice (even when stored in the fridge) can grow bacteria that can cause foodborne illness. Add a few drops of water or broth to keep the rice moist, then reheat the leftovers in the oven or microwave to a piping hot temperature (at least 165°F).

Freezer: This chicken and rice casserole freezes well for up to 3 months. If you plan to freeze an entire cooked casserole, cook it in an aluminum pan. Allow it to cool completely, then cover it with a layer of plastic freezer wrap and then a layer of aluminum foil.

To Reheat: If frozen, thaw the casserole in the fridge overnight. Reheat in the oven or microwave.

Make Ahead: This is a great make-ahead chicken casserole recipe. Prepare the dish but do not bake. Cover it well and store it in the refrigerator for 1 to 2 days before baking.

To Freeze Unbaked: Prepare the dish but do not bake. Cover it well with plastic wrap and foil and store it in the freezer for up to 3 months. Allow it to thaw overnight in the refrigerator before baking.

    Hi Stephanie,
    First, I wanted to thank you that we can reduce or increase a recipe!
    I wanted to ask you,
    What can I substitute the Pimento with?
    We don’t like pimento. I know it’s only 1 TBLS .
    Also, I have to substitute the bell pepper as I am highly allergic to them. So, I would replace it with onions.
    This recipe sounds for delicious!
    Thank you!!

    When I read 1 1/3 cup rice, I assumed uncooked. but since there is mostly zero liquid in this recipe, does that mean 1 1/3 cups cooked rice? It’s not a well written recipe at all. Not up to Stephanie’s usual standards.
