Instructions

Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish.
In a bowl, combine chicken, olive oil, lime juice, and all seasonings. Toss to coat and set aside.
In a skillet, sauté bell peppers and onions in olive oil until softened. Add garlic and cook 1 minute more.
In a large bowl, mix chicken, sautéed veggies, and softened cream cheese until evenly combined.
Spread mixture into the baking dish. Top with shredded cheese.
Bake uncovered for 30–35 minutes or until chicken is cooked through and cheese is bubbly.
Broil 1–2 minutes for a golden top, if desired.
Rest 5 minutes before serving. Garnish with cilantro and lime.

Notes

Add a can of black beans or corn to stretch the casserole for more servings.
Use pre-cooked rotisserie chicken for faster prep.
Let the dish rest after baking—it makes it easier to slice and serve.
