Ingredients

Scale
  • 4 large poblano peppers, roasted and peeled
  • 1 cup shredded Monterey Jack cheese
  • 1 cup shredded cheddar cheese
  • 1 can (14 oz) diced tomatoes
  • 1/2 cup diced onions
  • 2 cloves garlic, minced
  • 4 large eggs
  • 1/2 cup milk
  • 1/2 cup all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/4 cup chopped fresh cilantro
  • 1 tablespoon olive oil

Instructions

  1. Preheat the oven to 375°F (190°C). Lightly grease a 9×9-inch casserole dish.
  2. Roast the poblano peppers over an open flame or under the broiler until charred, then place in a sealed bag to steam for 10 minutes. Peel, seed, and chop the peppers.
  3. In a skillet, heat olive oil over medium heat. Add onions and garlic; sauté until translucent.
  4. Add diced tomatoes, cumin, salt, and pepper to the skillet. Simmer for 5 minutes to develop flavors. Remove from heat.
  5. In a mixing bowl, whisk together eggs, milk, flour, and baking powder until smooth.
  6. Layer half of the roasted peppers in the casserole dish. Sprinkle half of both cheeses over the peppers.
  7. Pour half of the egg mixture evenly over the cheese layer, then spoon half of the tomato mixture on top.
  8. Repeat layers: peppers, cheeses, egg mixture, and tomato mixture.
  9. Bake uncovered for 35-40 minutes or until the casserole is set and golden on top.
  10. Remove from oven and let rest for 5 minutes. Garnish with chopped cilantro and serve with sour cream if desired.

Notes

For extra heat, add diced jalapeños to the tomato sauce or top the casserole with sliced fresh chiles before baking.
