Ingredients
  

  • 6 large poblano peppers
  • 1 tablespoon olive oil
  • 1 small onion diced
  • 2 cloves garlic minced
  • 1 teaspoon cumin
  • ½ teaspoon smoked paprika
  • ½ teaspoon salt
  • ½ teaspoon black pepper
  • 1 cup shredded cheddar cheese
  • 1 cup shredded Monterey Jack cheese
  • 1 cup cooked ground beef or black beans for a vegetarian option
  • ½ cup corn
  • ½ cup sour cream
  • 2 eggs beaten
  • 1 cup milk
  • ½ cup all-purpose flour
  • 1 teaspoon baking powder

Instructions
 

  • Roast the poblanos: Preheat oven to 400°F (200°C). Place poblanos on a baking sheet and roast for 10 minutes until skins blister.
  • Peel and prep: Let peppers cool, then remove skins, seeds, and stems. Slice into strips.
  • Sauté the aromatics: Heat oil in a skillet over medium heat. Cook onions and garlic for 3 minutes. Add cumin, smoked paprika, salt, and pepper.
  • Assemble the filling: Stir in cooked beef (or beans), corn, and half the cheese. Remove from heat.
  • Mix the batter: In a bowl, whisk eggs, sour cream, milk, flour, and baking powder until smooth.
  • Layer the casserole: In a greased baking dish, spread half the batter. Add a layer of poblano strips and beef mixture. Repeat.
  • Top and bake: Sprinkle remaining cheese on top. Bake at 375°F (190°C) for 30 minutes or until golden and set.
  • Serve: Let cool for 5 minutes, then slice and enjoy.
