Variations
- Topping Options: A dollop of sour cream or Greek yogurt adds a cool, creamy contrast to the spicy casserole. Fresh avocado slices or guacamole bring a rich, buttery element that complements the other ingredients beautifully. For a bit of crunch, sprinkle some chopped green chiles or additional crushed tortilla chips on top. Additionally, salsa and black beans make great toppings.
- Cheese Variation: You can substitute Monterrey Jack cheese with mild cheddar cheese, Colby, or even pepper jack for a bit of extra spice. These cheeses melt well and offer a similar creamy texture.
How to Make Mexican Chicken Casserole
Step #1: Heat a large skillet over medium heat. Add chile pieces and toast for a few minutes until fragrant. Set aside in a bowl of hot water for 15 minutes.
Step #2: Puree with garlic, broth, and ½ cup soaking liquid in a blender. Add in the whole tomatoes and continue to puree. Run through a fine sieve and return to the pan. Stir in cumin, coriander, sugar, and salt. Simmer over medium-low for 10 minutes.
Step #3: Preheat oven to 350°F (175°C). Layer a 9×13 baking dish with half a bag of corn tortilla chips, using your hands to press the chips down and break them into pieces. Add half of the shredded chicken, then half of the sauce. Layer the remaining chips, chicken, and sauce, then top with shredded cheese.
Step #4: Bake, covered with well-greased foil, for 25 minutes. Remove foil, bake another 5 minutes until cheese is bubbly.
Step #5: Let sit for 15 minutes to cool and set, then garnish with cilantro, cherry tomatoes, green onions, Cotija cheese, and jalapeno (if using). Serve warm.

Expert Tips
- Blending Smoothly: For a smoother sauce, blend the ingredients in small batches if your blender is not powerful enough. This ensures all the ingredients are evenly pureed.
- Layering Technique: Pressing down the tortilla chips ensures they absorb the sauce and flavors better. Breaking them into smaller pieces helps in achieving a more even distribution.

Made this for dinner and everyone went back for seconds, it’s that good!!
This enchilada sauce is so good and so easy . . . I used Tomato Puree rather than whole tomatoes and I didn’t strain the sauce – because as someone else said, it didn’t seem necessary. I don’t think I’ll ever purchase sauce again!
Just made this for my family and it is great!. I also.didn’t strain tje.sauce as it seemed unnecessary. I dod.however add an in between layer of half.a wheel of.Cojhita with about 1 cup colby jack, 1 tablespoon fresh minced celentro and some cracked pepper and garlic salt. Yum!
