Ingredients
- 3 tablespoons olive oil
- 1 large yellow onion, diced
- 4 cloves garlic, minced
- 4 cups cooked shredded chicken (about 2 large breasts or 1 rotisserie chicken)
- 2 teaspoons ground cumin
- 1 teaspoon chili powder
- 1/2 teaspoon smoked paprika
- 1/4 teaspoon cayenne pepper (adjust to taste)
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 8 ounces cream cheese, softened
- 1 cup sour cream
- 1 cup chicken broth
- 1 can (10 ounces) diced tomatoes with green chiles, undrained
- 1 cup corn kernels (fresh, frozen, or canned)
- 1 can (4 ounces) diced jalapeños, drained (optional)
- 2 cups shredded Mexican blend cheese, divided
- 1 cup shredded cheddar cheese
- 12 corn or flour tortillas, cut into strips
- 2 cups tortilla chips, crushed
- Fresh cilantro for garnish
- Lime wedges for serving
Instructions
- Preheat your oven to 350°F and lightly grease a 9×13 inch baking dish with cooking spray or butter.
- Heat olive oil in a large skillet over medium heat. Add the diced onion and sauté for 4-5 minutes until it becomes translucent and fragrant.
- Add the minced garlic to the skillet and cook for another minute, stirring constantly, until you can smell that wonderful garlic aroma.
- In a small bowl, combine the cumin, chili powder, smoked paprika, cayenne pepper, salt, and black pepper to create your spice blend.
- Add the shredded chicken to the skillet with the onions and garlic, then sprinkle the spice blend over top and stir well to coat all the chicken evenly.
- Cook the chicken mixture for 2-3 minutes, stirring occasionally, until the spices are fragrant and have coated everything beautifully.
- In another bowl, whisk together the softened cream cheese, sour cream, and chicken broth until you have a smooth, creamy sauce with no lumps.
- Pour this cream mixture into the skillet with the chicken, stirring gently until everything is well combined and creamy.
- Add the diced tomatoes with green chiles (including the juice), corn kernels, and jalapeños if using, and stir everything together until well incorporated.
- Remove from heat and stir in 1 cup of the Mexican blend cheese and the cheddar cheese, mixing until the cheese is melted and the filling is creamy and cohesive.
- Spread a thin layer of the chicken mixture on the bottom of your prepared baking dish (about 1/2 cup).
- Create the first layer by arranging tortilla strips over the chicken mixture, breaking them to fit as needed.
- Add half of the remaining chicken mixture over the tortilla layer, spreading it evenly.
- Add another layer of tortilla strips, again breaking them to fit your dish.
- Top with the remaining chicken mixture, spreading it out to create an even layer.
- In a bowl, combine the crushed tortilla chips with the remaining 1 cup of Mexican blend cheese.
- Sprinkle this tortilla chip and cheese mixture evenly over the top of the casserole, making sure to cover all the filling.
- Place the baking dish on a baking sheet (this catches any spills) and bake for 35-40 minutes until the top is golden brown and crispy and the edges are bubbling.
- Remove from the oven and let the casserole rest for 5 minutes before serving—this helps it set and makes for cleaner portions.
- Garnish generously with fresh cilantro and serve with lime wedges, additional sour cream, and your favorite salsa on the side.
Pro Tips
Cooking Tips: For the best texture, use a combination of both corn and flour tortillas if you can find them—they create different layers of flavor and texture. If your cream cheese is too firm, soften it in the microwave for 15-20 seconds before mixing. Don’t overmix the filling once you add the cheese; just fold it in gently until combined.
Customization Ideas: Make it spicier by adding more cayenne pepper or using hot salsa instead of mild tomatoes with green chiles. Add black beans or refried beans to the filling for extra protein and depth. Substitute some of the sour cream with Greek yogurt for a healthier option. For a white chicken casserole version, use white wine or additional chicken broth instead of tomatoes.
Serving Suggestions: Serve with homemade chip dip on the side for dipping tortilla chips. Pair with Mexican rice, refried beans, or a crisp cilantro lime salad. Top individual servings with fresh avocado slices, diced red onion, and a dollop of sour cream.
Storage and Leftovers: Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently in a 325°F oven covered with foil for about 15 minutes until warmed through. The casserole can also be frozen for up to 3 months; thaw before reheating. Microwave reheating is possible but may make the tortilla chips less crispy.
Ingredient Substitutions: Use Greek yogurt instead of sour cream for a lighter version. Substitute rotisserie chicken with shredded turkey breast or pork. Use a combination of Monterey Jack and pepper jack cheese for more heat. Replace corn with zucchini or bell peppers if preferred. Use full-fat or reduced-fat cream cheese depending on dietary needs.
Why This Recipe Works: The layering technique ensures every bite has chicken, sauce, and that satisfying tortilla crunch. The cream cheese creates a luxurious sauce that won’t dry out in the oven. The tortilla chip topping adds textural contrast and seasoning. The combination of spices provides authentic Mexican flavor without being overwhelming. This is a forgiving recipe that tolerates slight variations in ingredient amounts and cooking times.
