Preheat your oven to 350°F (175°C) so it’s ready for your casserole.
If you haven’t already, cook your chicken breasts until they’re no longer pink in the center. You can grill, boil, or bake them—whatever you prefer! Once cooked, chop them into bite-sized pieces.
In a large mixing bowl, combine the cooked chicken, cooked rice, salsa verde, sour cream, sweet corn, diced green chilies, honey, lime juice, and all the spices (chili powder, onion powder, garlic powder, salt, smoked paprika, cumin, chipotle powder, and cayenne pepper). Mix until everything is well combined.
Add half of the Monterrey Jack and sharp cheddar cheese into the mixture and stir to incorporate. This will help create a cheesy filling throughout the casserole.
Pour the mixture into a greased baking dish, spreading it evenly. Top with the remaining Monterrey Jack and sharp cheddar cheese for that golden, bubbly finish.
Place the dish in the preheated oven and bake for about 25-30 minutes, or until the cheese is melted and bubbly and the casserole is heated through.
Once out of the oven, let it cool for a few minutes. Serve with tortilla chips, a drizzle of sour cream, fresh cilantro, and slices of avocado for an added touch of flavor!
