Servings: 6 servings

Ingredients

• 3 cups cooked, shredded chicken (rotisserie works great)
• 2 cups cooked rice (white or brown; day-old rice is ideal)
• 1 can (15 oz) black beans, drained and rinsed
• 1 cup corn kernels (frozen, canned, or fresh)
• 1 red bell pepper, diced
• 1 small yellow onion, diced
• 1 can (10 oz) diced tomatoes with green chiles (like Rotel), drained
• 1 cup salsa (mild or medium)
• 1 cup sour cream (or plain Greek yogurt)
• 1 cup shredded Monterey Jack cheese
• 1 cup shredded cheddar cheese
• 2 tablespoons olive oil
• 2 teaspoons chili powder
• 1 teaspoon ground cumin
• 1 teaspoon smoked paprika
• ½ teaspoon garlic powder
• Salt and black pepper, to taste
• Optional toppings: chopped cilantro, sliced green onions, diced avocado, lime wedges, jalapeño slices

Instructions

• Preheat the oven: Set to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
• Sauté the veggies: Heat olive oil in a large skillet over medium heat. Add onion and bell pepper with a pinch of salt. Cook 5–6 minutes until softened.
• Add seasonings: Stir in chili powder, cumin, smoked paprika, garlic powder, and a few grinds of pepper. Cook 1 minute until fragrant.
• Build the base: In a large bowl, combine cooked rice, shredded chicken, black beans, corn, and drained tomatoes with chiles. Add the sautéed veggies and stir gently.
• Make it creamy: In a separate bowl, whisk together salsa and sour cream. Taste and season with salt and pepper. Pour over the rice-chicken mixture and toss to coat evenly.
• Assemble: Spread half the mixture into the baking dish. Sprinkle with half the Monterey Jack and cheddar. Add the remaining mixture and top with the rest of the cheese.
• Bake: Cover loosely with foil and bake for 15 minutes. Remove foil and bake another 10–12 minutes, until the cheese is melted and the casserole is bubbling around the edges.
• Rest and finish: Let it rest 5–10 minutes to set. Top with cilantro, green onions, and any other favorite toppings. Serve with lime wedges for a bright finish.

Storage Instructions

• Refrigerator: Store in an airtight container for up to 4 days. Reheat in the microwave or covered in the oven at 325°F until warmed through.
• Freezer: Cool completely, then wrap tightly or portion into freezer-safe containers.

  Freeze up to 2 months. Thaw overnight in the fridge before reheating.

• Reheating tips: Add a splash of chicken broth or a spoon of salsa before reheating to keep it moist.

Benefits of This Recipe

• Balanced and satisfying: Protein from chicken and beans, fiber from beans and corn, and carbs from rice make it a complete meal.
• Kid-friendly flavors: Creamy, cheesy, and mild heat that you can adjust.
• Meal-prep ready: Easy to portion for lunches or make ahead for busy nights.
• Uses pantry staples: Beans, rice, and canned tomatoes help stretch your budget without sacrificing taste.

Common Mistakes to Avoid

• Overcooking the rice: Mushy rice makes the casserole too soft. Use just-cooked or day-old rice for the best texture.
• Skipping the spice bloom: Adding spices directly to the mix can taste flat.

  Cook them briefly with the veggies to unlock flavor.

• Too much liquid: Don’t skip draining the tomatoes. Excess moisture can make the casserole watery.
• Under-seasoning: Taste the creamy salsa mixture before combining. Adjust salt and pepper so the flavors pop.
• Overbaking: Bake just until hot and bubbly.

  Overbaking can dry out the chicken and dull the flavors.
