Ingredients and Preparation

To make this casserole, you’ll need ingredients divided into three parts: the marinated chicken, the casserole layers, and the guacamole topping. Each component adds a layer of flavor and texture that brings the dish together. Here’s what you’ll need:

Chicken Marinade Ingredients:

• 3 boneless, skinless chicken breasts (cut into bite-sized pieces)
• 3 garlic cloves, minced
• 1 teaspoon dried oregano
• 1 teaspoon salt
• 1 teaspoon black pepper
• ½ teaspoon cayenne pepper (optional for heat)
• 2 tablespoons sesame oil
• 1 can (12 oz) Mexican beer (like Modelo or Corona)

Casserole Ingredients:

• 12 small flour tortillas (or substitute with corn tortillas if preferred)
• 1 tablespoon olive oil (for cooking the marinated chicken)
• 1 cup shredded cheddar cheese or Mexican cheese blend
• 1 large tomato, diced
• 1 cup chopped lettuce
• Sour cream, for serving (optional)

Homemade Guacamole Topping:

• 1 ripe avocado
• 1 tomato, chopped
• 5 green onions, chopped
• Juice of 2 limes
• Salt and pepper to taste

Step-by-Step Instructions

Follow these steps to build your casserole from start to finish. This dish comes together easily and doesn’t require any advanced cooking techniques.

1. Prepare the Marinade
   In a large bowl, combine the minced garlic, oregano, salt, black pepper, cayenne pepper, sesame oil, and Mexican beer. Stir well to mix.
   Add the chicken pieces to the marinade and stir to coat them evenly. Cover the bowl with plastic wrap and place it in the refrigerator. Marinate the chicken for at least 1 hour, or ideally overnight, for maximum flavor.
2. Cook the Marinated Chicken
   After marinating, remove the chicken from the refrigerator and let it sit at room temperature for 10 minutes.
   Heat the olive oil in a large skillet over medium heat. Remove the chicken from the marinade, allowing the excess liquid to drip off.
   Add the chicken to the skillet and cook for about 7 to 10 minutes, until fully cooked and golden brown on the outside. Stir occasionally for even cooking. Once cooked, remove the chicken from the skillet and set aside.
3. Assemble the Casserole
   Preheat the oven to 375°F (190°C).
   Lightly grease a 9×13 inch baking dish.
   Take your tortillas and fill each one with a generous spoonful of the cooked chicken. Roll each tortilla and place it seam-side down in the baking dish. Continue until the dish is filled with rolled tortillas.
   Sprinkle the shredded cheese evenly over the top of the tortillas.
4. Bake the Casserole
   Place the baking dish in the preheated oven and bake for 10 to 12 minutes, or until the cheese is melted and bubbling and the edges of the tortillas are slightly crisp.
   Remove from the oven and let it rest for 5 minutes before serving.
5. Make the Guacamole
   While the casserole is baking, make the guacamole. In a medium bowl, mash the avocado until smooth but still chunky.
   Add the chopped tomato, green onions, lime juice, salt, and pepper. Stir everything together and adjust the seasoning to taste.
6. Serve
   Once the casserole is done, serve it hot with a generous topping of guacamole.
   Add chopped lettuce and diced tomatoes on top for freshness and crunch.
   Spoon on a dollop of sour cream if desired.

Beginner Tips and Notes

• Marinating Matters: The longer the chicken marinates, the deeper the flavor. If you’re pressed for time, even 30 minutes of marinating will still enhance the taste.
• No Beer Option: If you don’t want to use beer, you can substitute with chicken broth and a splash of apple cider vinegar or lime juice for acidity.
• Cheese Choices: Use what you have on hand. Cheddar, Monterey Jack, or a blend all work well. Avoid cheeses that don’t melt smoothly.
• Tortilla Tips: Flour tortillas roll easier, but corn tortillas add more texture and authentic flavor. Slightly warm them before rolling to prevent cracking.
• Extra Fillings: You can add beans, sautéed onions, or corn to the filling for added volume and flavor.
• Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven to keep tortillas crisp.
• Freezing Option: Assemble the casserole without baking and freeze it. Thaw in the fridge overnight and bake when ready.

Serving Suggestions

• Mexican rice or cilantro-lime rice
• Black beans or pinto beans
• Fresh corn salad or grilled vegetables

For a full spread, serve with a chilled glass of lime water or a refreshing agua fresca. If you’re hosting, a side of tortilla chips with salsa or queso dip complements this dish well.
