Mexican Chicken Casserole

Ingredients

  • 2 tbsp oil: A healthy option like avocado oil works wonders for flavor.
  • 1 cup finely-chopped onion: Fresh onions elevate the base flavor. Yellow or red onions both work beautifully!
  • 2 tsp kosher salt (divided): Use kosher or sea salt for the best flavor.
  • 1 tbsp minced garlic: Fresh garlic can make a huge difference; however, pre-minced works in a pinch.
  • 3 cups shredded rotisserie chicken: An easy way to add protein; feel free to grill and shred your own if you have the time!
  • 3 tbsp chili powder: Definitely don’t skip this for that authentic Mexican flavor!
  • 2 cups cooked rice: I typically use brown rice for a heartier dish, but white rice works as well.
  • 1 (15 oz) can black beans, rinsed and drained: These add great texture and protein!
  • 1 cup frozen corn: Sweet corn balances the flavors perfectly.
  • 1 cup jarred salsa: Choose your favorite brand! I highly recommend a chunky salsa for more texture.
  • 1 cup sour cream (or Greek yogurt): Either option adds creaminess and tang.
  • 3 cups shredded Mexican blend or cheddar cheese (divided): Freshly shredded cheese melts better than pre-shredded, but both work!

Optional Toppings:

  • Sliced avocado
  • Fresh cilantro
  • Sliced green onion
  • Jalapeños for extra heat
  • Extra salsa or sour cream for drizzling

Prep Notes: Let the rotisserie chicken cool to room temperature before shredding for easier handling.

Step-by-Step Instructions

  1. Preheat Your Oven: Set it to 375°F. Lightly grease a 9×13-inch baking dish with cooking spray or oil. (Pro tip: lining with parchment paper makes for easy cleanup!)

  2. Sauté Your Aromatics: Heat 2 tbsp oil in a Dutch oven or large skillet over medium heat. Add the onion and ½ tsp of kosher salt. Sauté for about 5 to 7 minutes, stirring occasionally, until the onion is soft and golden. Stir in the minced garlic and cook for another minute until fragrant.

  3. Add the Chicken and Spices: Toss in the shredded chicken and 3 tbsp chili powder. Stir to coat the chicken evenly, cooking for an additional 2 to 3 minutes to warm through and let those spices expand their flavors. Turn off the heat.

  4. Mix in the Goodness: Stir in the cooked rice, black beans, frozen corn, salsa, sour cream, the remaining 1½ tsp kosher salt, and 1 cup of the shredded cheese. Mix thoroughly to combine everything. If your skillet is too small, transfer the mixture to a large bowl to combine.

  5. Spread the Filling: Pour the filling into your prepared baking dish and spread it evenly. Top with the remaining 2 cups of shredded cheese.

  6. Bake: Place the dish in the oven and bake for 20 to 25 minutes or until you see it bubbling and the cheese is golden on top. Give it a few minutes to cool before serving.

  7. Serve and Enjoy: Add any desired toppings right before digging in. It’s a family meal everyone will love!

  • Make-Ahead: Prepare the casserole a day in advance, cover it tightly, and store it in the fridge. Bake it just before serving!

  • Troubleshooting: If your casserole is too dry, consider adding a splash of chicken broth before you bake it. If it’s too runny, let it bake longer to thicken.

  • Cheese Choice: For maximum flavor, I recommend using a mix of cheddar and pepper jack for a little kick!

  • Spice Level: If you want to kick up the heat, use hot salsa or add sliced jalapeños into the filling.


Serving Suggestions
