Ingredients

4 cups cooked, shredded chicken — Pre-cooked chicken works best; rotisserie or leftover roasted chicken adds moist, seasoned meat.
2 cups instant rice — Use the instant white rice called for in the recipe; it soaks up the liquids during baking for a soft finish.
1 can (10.5 oz) cream of chicken soup — Adds creaminess and savory depth; no need to dilute beyond the recipe liquids.
1 cup sour cream — Provides tang and richness that keeps the casserole creamy after baking.
1 cup frozen diced onion and bell pepper mix — Use the frozen mix directly from the bag; it thaws and cooks in the casserole.
1 can (10 oz) diced tomatoes with green chilies — Adds moisture, acidity, and a gentle kick from the chilies.
1.5 cups chicken broth — Helps cook the instant rice and keeps the casserole saucy and tender.

Step-by-Step Instructions

Preheat your oven to 350°F (175°C). Make sure the oven rack is centered so the casserole heats evenly.
In a large mixing bowl, combine 4 cups cooked, shredded chicken, 2 cups instant rice, 1 can (10.5 oz) cream of chicken soup, 1 cup sour cream, 1 cup frozen diced onion and bell pepper mix, 1 can (10 oz) diced tomatoes with green chilies with their juices, and 1.5 cups chicken broth. Mix well until all ingredients are fully combined. Tip: Stir gently to avoid over-shredding the chicken while ensuring the rice is evenly distributed.
Pour the mixture into a greased 9×13 inch casserole dish. Spread it to an even layer so it bakes uniformly.
Cover with foil and bake for 30 minutes. The foil traps steam so the rice can absorb the broth and soften.
Remove the foil and bake for an additional 15-20 minutes, or until heated through and bubbly. Watch the top during the final minutes so it does not overbake.
Let it cool for a few minutes before serving. Resting helps the casserole set for easier serving.

Tips, Storage & Variations

Tips
- Use warm chicken and warmed broth for quicker baking and more even temperature throughout the mixture.
- If your instant rice package lists specific liquid directions, follow the casserole proportions exactly to match the recipe texture.
- Leftovers reheat well in the oven at 350°F until warmed or in the microwave for quick single servings.
Storage
- Refrigerate: Store covered in the refrigerator for up to 3 days in an airtight container.
- Reheat: Warm individual portions in the microwave or reheat the whole dish covered at 325°F until heated through.
Freezing
- Freeze before baking: Assemble in a freezer-safe dish, cover tightly, and freeze for up to 3 months. Thaw in the refrigerator overnight, then bake as directed.

Flavor variations using only the existing ingredients
- Extra creamy: Stir an additional 1/4 to 1/2 cup sour cream into the mixture before baking for a richer texture.
- Spicier kick: Mix in more of the diced tomatoes with green chilies from the can to increase the heat level.
- More veg forward: Add an extra cup of the frozen onion and bell pepper mix folded in before baking to boost the vegetable presence.
