Step-by-Step Instructions
- Prepare the Chicken:
- Coat chicken with olive oil then sprinkle all over with taco seasoning salt and pepper. Let sit a few minutes so flavors absorb.
- Sear the Chicken:
- Set a large oven safe skillet to medium heat. Add chicken and sear for about two minutes per side until golden. This helps lock in moisture.
- Simmer the Chicken:
- Pour in beer or chicken broth reduce heat to low and cover. Simmer for fifteen to twenty minutes until the chicken is cooked through. Shred with two forks for the perfect bite texture.
- Sauté the Vegetables:
- In the same pan heat more olive oil. Add chopped onion poblano and jalapeno. Cook for five minutes stirring regularly until softened.
- Bloom the Spices and Garlic:
- Stir in garlic cumin oregano salt and pepper. Cook one more minute until the pan smells aromatic.
- Mix Filling:
- In a large bowl combine shredded chicken vegetables salsa and black beans. Mix well to get a little salsa on every piece.
- Layer the Casserole:
- Spoon some filling onto the bottom of the skillet or into a baking dish. Layer half the tortillas on top then sprinkle over half the cheese.
- Layer Again and Top:
- Spread remaining filling over tortillas then finish with another layer of tortillas and remaining cheese.
- Finish in the Oven:
- Place skillet under the broiler for five minutes until cheese is melted and bubbly. If preferred you can bake at three hundred fifty degrees Fahrenheit for fifteen minutes instead.
- Garnish and Serve:
- Let the casserole cool briefly. Sprinkle freshly chopped cilantro on top before serving.

I have a soft spot for poblanos in this dish. I remember my sister calling me after making it for her book club—everyone wanted to know the secret ingredient and it was that earthy pepper. It always makes the dish special.
Storage Tips
Store leftovers in an airtight container for up to four days in the refrigerator. The flavors often deepen after a day. For freezing slice portions and wrap tightly for up to three months. Reheat covered in the oven or microwave until steaming hot.
Ingredient Substitutions
You can swap black beans for pinto beans or even use cooked lentils. For a dairy free casserole use plant based cheese which melts well. Rotisserie chicken is a time saving alternative with equally great results.
Serving Suggestions
Serve slices with a drizzle of Mexican crema or a dollop of sour cream. A side of crisp lettuce or tangy slaw balances the richness. Warm up extra tortillas for scooping up saucy bites.

Cultural Context
This dish is inspired by traditional Mexican enchiladas verdes where tangy green salsa and roasted poblano create a distinct flavor profile. Layers and melty cheese give it that comforting American casserole touch making it a bridge between two food cultures I love.
