Ingredients

4 large poblano peppers, roasted, peeled, and sliced
2 cups cooked shredded chicken
1 cup corn kernels (fresh or frozen)
1 cup black beans, drained and rinsed
1 cup diced tomatoes (canned or fresh)
2 cups shredded Mexican blend cheese
1 cup cream or half-and-half
1/2 cup sour cream
1 small onion, finely chopped
2 cloves garlic, minced
1 tsp ground cumin
1/2 tsp smoked paprika
1/2 tsp chili powder (optional for extra heat)
1 tbsp olive oil
Salt and pepper to taste
Fresh cilantro for garnish

Instructions

Preheat the Oven: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
Prepare the Poblanos: Roast the poblano peppers over a gas flame, under a broiler, or on a skillet until charred on all sides. Place in a bowl and cover with plastic wrap for 10 minutes to steam. Peel off the skins, remove seeds, and slice into strips.
Cook the Aromatics: In a skillet, heat olive oil over medium heat. Sauté onions until translucent, about 5 minutes. Add garlic, cumin, smoked paprika, and chili powder; cook for another 1–2 minutes until fragrant.
Combine Filling: In a large bowl, combine shredded chicken, corn, black beans, diced tomatoes, sautéed onion mixture, cream, and sour cream. Season with salt and pepper to taste. Mix until well combined.
Assemble the Casserole: Layer half of the roasted poblano slices at the bottom of the prepared baking dish. Spread half of the filling over the poblanos. Sprinkle 1 cup of shredded cheese evenly. Repeat with remaining poblanos, filling, and top with remaining cheese.
Bake: Cover the dish with aluminum foil and bake for 20 minutes. Remove foil and bake for an additional 10–15 minutes, or until the cheese is bubbly and golden brown.
Garnish and Serve: Let the casserole rest for 5 minutes before serving. Garnish with fresh cilantro and a dollop of sour cream if desired. Serve warm.

Tips for the Perfect Poblano Casserole

Roasting Poblanos: Roasting adds smoky depth to the dish. If you prefer a milder flavor, remove all seeds; for more heat, leave some seeds intact.
Cheese Options: Feel free to use Monterey Jack, cheddar, or a Mexican cheese blend. A mix of cheeses can enhance flavor complexity.
Make Ahead: Assemble the casserole a day in advance, cover, and refrigerate. Bake just before serving for convenience.
Vegetarian Version: Substitute chicken with additional beans or sautéed mushrooms for a meatless option.
Freezing: This casserole freezes well. Bake from frozen by adding an extra 10 minutes to the cooking time.

Variations

Spicy Poblano Casserole: Add diced jalapeños or a few dashes of hot sauce to the filling.
Creamy Corn Poblano Casserole: Add a cup of creamed corn for a sweeter, creamier texture.
Southwest Twist: Mix in cooked quinoa or rice for a hearty, grain-packed casserole.
Cheese Lovers: Top with a mix of shredded pepper jack and cheddar for a melty, spicy finish.
