This Fajita Chicken Casserole Bake combines tender shredded chicken, fajita-seasoned vegetables, creamy soup, and melted cheese into one bubbling, flavor-packed oven dish.
Main Base:
4 cups (approximately 600 g) shredded cooked chicken breast
2 cups (370 g) uncooked instant white rice
1 can (298 g / 10.5 oz) cream of chicken soup
1 cup (240 g) sour cream
1 cup (140 g) frozen diced onion and bell pepper blend
1 can (284 g / 10 oz) diced tomatoes with green chilies, undrained (e.g., Rotel)
360 ml (1½ cups) chicken broth
1 packet (32 g / 1.25 oz) fajita seasoning
Cheese Topping:
1 bag (227 g / 8 oz) shredded Mexican-style cheese blend
Preheat your oven to 175°C (350°F).
Lightly grease a 23×33 cm (9×13-inch) baking dish with nonstick spray or oil.
In a large mixing bowl, combine the following:
4 cups shredded cooked chicken
2 cups uncooked instant white rice
1 can cream of chicken soup
1 cup sour cream
1 cup frozen diced onion and bell pepper blend
1 can diced tomatoes with chilies (do not drain)
360 ml chicken broth
1 packet fajita seasoning
Half of the shredded Mexican cheese blend (save the rest for topping)
Mix thoroughly until well combined.
Pour the mixture evenly into the greased baking dish.
Use a spatula to spread the top flat for even baking.
Cover the dish tightly with aluminum foil.
Bake in the preheated oven for 35 minutes.
Remove foil.
Sprinkle the remaining cheese evenly over the top.
Return to oven and bake uncovered for 10 more minutes, or until the cheese is melted and bubbly.
Remove from oven and let rest for 5–10 minutes before serving.
This helps the casserole set and makes slicing easier.
Chicken: Use leftover rotisserie chicken for convenience and extra flavor. You can shred it easily using forks or a mixer.
Rice: Instant white rice is essential for this recipe. Long-grain or brown rice won’t cook properly unless pre-cooked.
Spice Level: For a milder dish, use plain diced tomatoes instead of ones with chilies. For more heat, add sliced jalapeños or cayenne pepper.
Vegetarian Version: Substitute chicken with canned black beans, corn, or seasoned tofu.
Low-Carb Version: Use cauliflower rice instead of instant rice for a keto-friendly alternative.
Make Ahead: You can assemble the entire casserole a day in advance, refrigerate, and bake when ready.
