Ingredients Section

Here’s what you’ll need to create this delicious Mexican Chicken Casserole:

  • 2 tbsp oil (I prefer avocado oil for its neutral flavor and high smoke point)
  • 1 cup finely-chopped onion (sweet onions work beautifully, but any onion will do)
  • 2 tsp kosher salt (divided; use coarse salt for better flavor absorption)
  • 1 tbsp minced garlic (fresh garlic adds a punch, but jarred can work in a pinch)
  • 3 cups shredded rotisserie chicken (super convenient! Just make sure to remove the skin)
  • 3 tbsp chili powder (choose a good quality blend for optimal flavor)
  • 2 cups cooked rice (leftover rice works perfectly, or use quinoa for a healthy twist)
  • 1 15 oz can black beans, rinsed and drained (a great source of protein!)
  • 1 cup frozen corn (no need to thaw; it will cook beautifully in the oven)
  • 1 cup jarred salsa (choose your favorite brand; I love a medium heat salsa)
  • 1 cup sour cream (or Greek yogurt for a healthier option)
  • 3 cups shredded Mexican blend or cheddar cheese (divided; I prefer pre-shredded cheese for convenience)
  • Optional toppings: sliced avocado, cilantro, sliced green onion, jalapeños, extra salsa, or sour cream (get creative here!)

Preparation Notes:

  • Use ingredients at room temperature for best results, especially the sour cream and cheese.
  • If you’re substituting any ingredients, aim for similar textures and flavors to maintain the essence of the dish.

Step-By-Step Instructions

  1. Preheat & Prepare: Preheat your oven to 375°F. Lightly grease a 9×13-inch baking dish with cooking spray or oil. For easy cleanup, line the dish with parchment paper.

  2. Sauté the Aromatics: Heat 2 tbsp of oil in a Dutch oven or large skillet over medium heat. Add the chopped onion and 1/2 tsp of kosher salt. Sauté for 5 to 7 minutes until the onions are soft and golden. Stir in the minced garlic and cook for an additional minute until fragrant.

  3. Add Chicken & Spices: Toss in the shredded rotisserie chicken and chili powder, stirring to evenly coat the chicken. Allow it to warm through for 2 to 3 minutes—this lets the flavors bloom. Turn off the heat.

  4. Combine the Filling: Stir in the cooked rice, black beans, frozen corn, salsa, sour cream, remaining 1 1/2 tsp kosher salt, and 1 cup of the shredded cheese. If needed, move the mixture to a large bowl for easy combining.

  5. Transfer to Baking Dish: Spread the filling evenly into the prepared baking dish. Top with the remaining 2 cups of shredded cheese, creating a delicious cheesy crust.

  6. Bake: Place the casserole in the oven and bake for 20 to 25 minutes or until hot, bubbly, and golden on top. Let it cool for a few minutes before scooping.

  7. Serve & Enjoy: Add any toppings you love, like sliced avocado or extra salsa, and serve warm. Enjoy the love and comfort in every bite!
