This chicken and wild rice casserole is an old-school recipe that’s been around for years. The kind of dish you taste at a ladies luncheon and immediately start asking around to find out who brought it. That’s exactly how I first discovered this chicken and wild rice casserole, and I went home with a mission to track it down, finding a version in Southern Living.
It’s creamy, comforting, and made with familiar ingredients. Nothing fancy, but the wild rice and water chestnuts give it a little something extra to balance the cheesy creaminess.
This recipe also makes a generous amount, which is part of what’s made it such a go-to for giving over the years. It’s perfect for feeding a large group, bringing to a potluck, or dividing up for sharing with someone who needs a meal!

How to Make Chicken and Wild Rice Casserole (Step-by-Step).




1. Cook the rice according to package directions and set aside.
2. Sauté the vegetables. Melt the butter in a large skillet over medium heat. Add the onions, celery, and water chestnuts and cook until tender, about 10 minutes.
SH&H Tip: If you sauté the vegetables in a large Dutch oven rather than a skillet, you can mix the remaining ingredients directly into the pot afterward instead of transferring everything to a bowl, using fewer dishes.
3. Mix the casserole. In a large bowl, combine the cooked rice, sautéed vegetables, cooked chicken, 3 cups of the cheese, cream of mushroom soup, sour cream, milk, salt, and pepper. Stir until everything is well combined.
4. Assemble. Spread the mixture evenly into a lightly greased 10×15-inch baking dish. Sprinkle with breadcrumbs, if using.

5. Bake. Bake uncovered at 350°F for 30 minutes. Sprinkle with the remaining 1 cup of cheese and bake 5 minutes more, until melted and bubbly.

Notes
- Use a fast-cooking long-grain and wild rice blend. Regular wild rice will not cook properly in this casserole.
- If you sauté the vegetables in a large Dutch oven, you can mix the remaining ingredients directly into the pot instead of dirtying a mixing bowl.
- This recipe can be divided into smaller pans and frozen baked or unbaked.
- Leftovers keep well in the refrigerator for up to 4 days. This casserole can be frozen baked or unbaked. If freezing, wrap tightly and remove the plastic wrap before reheating. The remaining 1 cup of cheese can be added before freezing or added after reheating. When reheating from frozen or refrigerated, bake covered at 350°F until heated through, then uncover, add the cheese if needed, and bake about 5 minutes more until melted.
Storage, Freezing, and Reheating.
This is a generous recipe, which makes it easy to divide into two aluminum half pans for sharing—whether you’re putting together a meal train, cooking for a new mom, or bringing a casserole to a potluck.
Leftovers keep well in the refrigerator for up to 4 days, covered tightly.
Freezing Instructions.
You can freeze this casserole baked or unbaked.
- Divide into one or two aluminum foil pans, if desired.
- Wrap each pan tightly with plastic wrap, pressing it directly against the surface of the casserole.
- Cover the pan with a second layer of heavy-duty aluminum foil to prevent freezer burn.
- Label and freeze for up to 2 months.
Reheating.
Remove the plastic wrap and then put the foil cover back on. Bake at 350°F until heated through and bubbling around the edges. If the remaining 1 cup of cheese was not added before freezing, sprinkle it over the top, uncover, and bake for about 5 minutes more until melted and warmed through.
For faster reheating, the casserole can be thawed overnight in the refrigerator before baking.

Can I halve this recipe?

Can I make this ahead of time?
