🍗 Pioneer Woman Tex Mex Chicken Casserole Ingredients
- 2 tbsp olive oil
- 1 large yellow onion, diced
- 2 bell peppers (red and green), seeded and diced
- 3 cloves garlic, minced
- 4 cups cooked chicken, shredded (rotisserie chicken works best)
- 1 can (15 oz) black beans, drained and rinsed
- 1 can (15 oz) whole kernel corn, drained
- 1 can (10 oz) Rotel (diced tomatoes and green chilies)
- 1 tbsp chili powder
- 2 tsp ground cumin
- 1 cup sour cream
- 1/2 cup mayonnaise
- 3 cups cheddar cheese, grated (divided)
- 1 bag (10 oz) tortilla chips, slightly crushed
- 1/4 cup fresh cilantro, chopped (for garnish)

🥘 How To Make Pioneer Woman Tex Mex Chicken Casserole
- Preheat the oven: Set your oven to 190°C (375°F) and lightly grease a 9×13 inch baking dish.
- Sauté the vegetables: Heat the olive oil in a large skillet over medium-high heat, add the onion and bell peppers, and cook for 5 minutes until soft; stir in the garlic for the last minute.
- Mix the filling: In a very large bowl, combine the shredded chicken, sautéed vegetable mixture, black beans, corn, Rotel (with juices), chili powder, cumin, sour cream, mayonnaise, and half of the cheese (1.5 cups).
- Layer the casserole: Spread half of the crushed tortilla chips across the bottom of the prepared baking dish, then spread the entire chicken mixture evenly over the chips.
- Top and bake: Sprinkle the remaining cheese and the remaining crushed chips over the top of the casserole.
- Bake until bubbly: Place the dish in the oven and bake for 20 to 25 minutes until the cheese is melted and bubbling, then garnish with fresh cilantro before serving.

🌟 Recipe Tips:
- Use Rotisserie Chicken: To save time and add flavor, use a store-bought rotisserie chicken. The meat is tender and seasoned, which boosts the overall taste of the casserole.
- Don’t crush chips too small: When crushing the tortilla chips, leave them in bite-sized chunks rather than crumbs. This maintains a nice crunch rather than turning into a mushy paste.
- Adjust the heat: The “Rotel” tomatoes come in mild, original, and hot varieties. Choose the one that fits your family’s spice tolerance.
- Grate your own cheese: Pre-shredded cheese contains anti-caking agents that prevent it from melting smoothly. Grating a block of sharp cheddar yields a much creamier texture.

♻️ How To Store Leftovers Tex Mex Chicken Casserole?
- Refrigerate: Cover the baking dish tightly with foil or transfer leftovers to an airtight container. Store in the fridge for up to 3 days.
- Freeze: You can freeze the unbaked casserole (without the top layer of chips) for up to 3 months.
- Thaw: Thaw in the fridge overnight before baking, adding fresh chips on top right before it goes in the oven.
♨️ How To Reheat Leftovers Tex Mex Chicken Casserole?
- In The Oven (Best Results):Cover the dish with foil and bake at 175°C (350°F) for 20 minutes. Remove the foil for the last 5 minutes to re-crisp the chips.
- In The Microwave (Fastest): Heat individual portions on a plate for 1 to 2 minutes until hot. Tip: Crumbled fresh chips on top after heating adds the crunch back.
- In The Air Fryer: Reheat a single slice at 160°C (320°F) for 5 to 6 minutes until the cheese is bubbling and golden.

💭FAQs
Yes, you can assemble the casserole up to the point of baking and store it in the fridge for up to 24 hours. However, hold off on adding the tortilla chips until just before baking so they stay crisp.
The mayonnaise adds a rich creaminess and tang that sour cream alone doesn’t provide. If you really dislike mayo, you can substitute it with cream of chicken soup or Greek yogurt.
You can, but you will miss the specific flavor of the green chilies. If using fresh tomatoes, add a small can of diced green chilies to the mix to replicate the flavor profile.
