Ingredients

Scale

Roasted Green Chiles

  • 6 large, peeled and seeded roasted green chiles

Cheese

  • 2 cups shredded Monterey Jack cheese
  • 1 cup shredded sharp cheddar cheese

Egg Mixture

  • 5 large eggs
  • 1/2 cup whole milk
  • 2 tablespoons all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper

Other

  • Cooking spray or butter, for greasing the baking dish

Instructions

  1. Preheat Your Equipment: Preheat your oven to 375°F (190°C). Lightly grease your baking dish with butter or cooking spray to ensure the casserole doesn’t stick and achieves a golden crust.
  2. Combine Ingredients: In a large mixing bowl, whisk together the eggs, whole milk, all-purpose flour, baking powder, salt, and black pepper until you have a smooth, well-blended mixture.
  3. Prepare Your Cooking Vessel: Arrange half of the roasted green chiles evenly on the bottom of the greased baking dish, creating the first layer of your casserole.
  4. Assemble the Dish: Sprinkle half of the shredded Monterey Jack and sharp cheddar cheeses over the layer of chiles. Then add the remaining chiles on top, followed by the rest of the cheeses. Pour the egg mixture evenly over all the layers to bind everything together.
  5. Cook to Perfection: Place the casserole dish uncovered in the preheated oven and bake for 30 to 35 minutes. Bake until the top turns a rich golden color and the center is fully set, indicating it’s cooked through.
  6. Finishing Touches: Once baked, remove the casserole from the oven and allow it to rest for at least 10 minutes. This resting time helps the casserole firm up, making it easier to slice and serve.
  7. Serve and Enjoy: Optionally, garnish with fresh cilantro leaves, slices of ripe avocado, or a drizzle of sour cream to add freshness and creaminess to each serving. Serve warm and enjoy your comforting chile rellenos casserole.

Notes

  • Peeling and seeding the roasted green chiles helps reduce bitterness and enhances their smoky flavor.
  • You can substitute whole milk with 2% milk for a slightly lighter dish.
  • Ensure the egg mixture is well whisked to achieve a light, souffle-like texture.
  • Allow the casserole to rest after baking to avoid it falling apart when sliced.
  • For added spice, consider incorporating a pinch of cayenne pepper into the egg mixture.
  • This casserole pairs well with a fresh green salad or Mexican rice for a complete meal.
