Preheat oven to 350°F and grease a 9x13-inch baking dish.
In a small bowl, combine chili powder, cumin, paprika, garlic powder, onion powder, salt, and pepper. Use half the spice mixture to coat the chicken. Toss until evenly seasoned.
Heat oil in a large skillet over medium-high heat. Sauté the seasoned chicken until lightly browned. It doesn’t need to be cooked through, then removed from heat.
Transfer chicken to the baking dish then add the peppers, onion, and green chilis, followed by the rice, remaining spices, half the cheese and chicken broth. Toss lightly to combine.
Cover casserole dish tightly with foil and bake for 35-40 minutes, or until the rice is fully cooked and tender.
Remove the foil and sprinkle the Mexican cheese blend over the top. Return to the oven uncovered for an additional 5-10 minutes, or until the cheese is melted and bubbly.
Notes
Adjust the chili powder or add a dash of cayenne pepper if you like it spicier.
Make sure the casserole dish is covered tightly with foil to ensure the rice cooks evenly and absorbs the liquid properly.
