  • 1 cup frozen corn No need to thaw.

Method
 

Preparation
  1. Preheat your oven to 375°F. Lightly grease a 9×13-inch baking dish with cooking spray or oil.
  2. Heat 2 tbsp of oil in a Dutch oven or large skillet over medium heat. Add the finely chopped onion and 1/2 tsp of kosher salt. Cook for 5 to 7 minutes, stirring occasionally, until softened and golden.
  3. Stir in the minced garlic and cook for an additional minute until fragrant.
Cooking
  1. Add the shredded chicken and chili powder to the pan. Stir well to coat the chicken uniformly. Allow it to heat through for 2 to 3 minutes to let the spices bloom. Turn off the heat.
  2. Merge in the cooked rice, black beans, frozen corn, salsa, sour cream, and remaining 1 1/2 tsp of kosher salt along with 1 cup of shredded cheese. Mix everything together until fully combined.
  3. Spread the filling evenly into the prepared baking dish, and top with the remaining 2 cups of shredded cheese.
  4. Bake for 20 to 25 minutes or until the casserole is hot, bubbly, and golden on top.
  5. Let cool for a few minutes before scooping, and add any optional toppings before serving warm.

Notes

For an extra layer of flavor, try roasting your veggies before adding them to the casserole. This casserole keeps well in the fridge for about 3 days in an airtight container.
