Ingredients

• 4 cups cooked, shredded chicken — pre-cooked chicken provides the protein base and texture, use roasted or rotisserie chicken for convenience.
• 2 cups instant rice — quick-cooking rice that will absorb the liquids and finish in the oven.
• 1 can (10.5 oz) cream of chicken soup — adds creaminess and savory depth to bind the casserole.
• 1 cup sour cream — contributes tang and richness to the sauce.
• 1 cup frozen diced onion and bell pepper mix — provides classic fajita flavor and color, no chopping required.
• 1 can (10 oz) diced tomatoes with green chilies — adds brightness and gentle heat, include the juices for flavor.
• 1.5 cups chicken broth — thins the mixture enough for the rice to cook and adds savory moisture.

Step-by-step Instructions

1. Preheat your oven to 350°F (175°C). Grease a 9×13 inch casserole dish so the casserole does not stick.
2. In a large mixing bowl, combine the 4 cups cooked, shredded chicken and 2 cups instant rice. Stir to distribute the rice evenly through the chicken.
3. Add the 1 can (10.5 oz) cream of chicken soup and 1 cup sour cream to the bowl. Mix until the dairy and soup coat the chicken and rice. A rubber spatula helps get everything evenly incorporated.
4. Fold in 1 cup frozen diced onion and bell pepper mix and 1 can (10 oz) diced tomatoes with green chilies, including their juices. Pour in 1.5 cups chicken broth and stir until all ingredients are fully combined. Tip: scrape the sides and bottom of the bowl to ensure no dry rice pockets remain.
5. Pour the combined mixture into the greased 9×13 inch casserole dish, spreading it into an even layer.
6. Cover the dish tightly with foil and bake for 30 minutes to allow the rice to absorb the liquid and flavors.
7. Carefully remove the foil and bake uncovered for an additional 15 to 20 minutes, or until the top is bubbly and the casserole is heated through. The edges should be slightly golden and the center steaming.
8. Let the casserole cool for a few minutes before serving to set. Tip: allow 5 to 10 minutes resting time so slices hold their shape when served.
