HOW TO MAKE PIONEER WOMAN MEXICAN CHICKEN CASSEROLE
Let’s dive into the step-by-step process that transforms these ingredients into a soul-warming bake. You’ll build layers of flavor and texture, finishing with that signature golden cheese topping.
1. Preheat your oven to 375°F (190°C) to ensure even, reliable baking from the moment you slide the casserole in.
2. In a large skillet, heat the olive oil over medium heat until it’s shimmering lightly across the pan.
3. Add the diced onion and red bell pepper to the skillet. Sauté them for about 5 minutes until they turn soft and begin to caramelize, releasing their natural sweetness.
4. Stir in the minced garlic and cook for an additional 1 minute until you can smell that irresistible garlic fragrance fill your kitchen.
5. Stir in the cooked and shredded chicken breast, then sprinkle in the ground cumin, chili powder, smoked paprika, salt, and pepper. Toss everything together so the spices coat the chicken evenly.
6. Add the Rotel diced tomatoes with green chilies, thawed corn, black beans, and chopped cilantro. Stir well to combine all those vibrant colors and flavors into one harmonious mixture.
7. Remove the skillet from heat and fold in the sour cream until the filling becomes luxuriously creamy and well-blended.
8. Begin assembling the casserole in a 9×13-inch baking dish by spreading a thin layer of the chicken mixture on the bottom. This first layer ensures every tortilla gets a hit of flavor.
9. Layer 5 corn tortillas over the chicken, overlapping slightly to cover the base completely.
10. Spread half of the remaining chicken mixture over the tortillas, then sprinkle with half of the grated cheddar and Monterey Jack cheeses for that irresistible melty layer.
11. Add another layer of 5 corn tortillas, top with the rest of the chicken mixture, and finish with the remaining cheese for a golden, bubbly finish.
12. Cover the dish tightly with foil and bake in the preheated oven for 20 minutes to allow flavors to meld and the tortillas to soften.
13. Remove the foil and bake for an additional 10–15 minutes until the cheese turns bubbly and golden brown.
14. Finally, let the casserole rest for a few minutes before serving so it sets into neat, sliceable squares.
