Ingredients
Chile and Cheese
- 6 large roasted green chiles, peeled and seeded
- 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
- Preheat Your Equipment: Preheat your oven to 375°F (190°C). Lightly grease your baking dish with butter or cooking spray to prevent sticking and help develop a golden edge on the casserole.
- Combine Ingredients: In a medium mixing bowl, whisk together the eggs, whole milk, all-purpose flour, baking powder, salt, and black pepper until the mixture is smooth and uniform, ensuring the flour is fully incorporated for a cohesive texture.
- Prepare Your Cooking Vessel: Spread half of the roasted green chiles evenly across the bottom of the greased baking dish to form the base layer for the casserole.
- Assemble the Dish: Sprinkle half of both cheeses (Monterey Jack and sharp cheddar) evenly over the layer of chiles. Then layer the remaining roasted chiles on top, followed by the rest of the shredded cheeses. Finally, pour the egg mixture evenly over all layers, coating everything thoroughly.
- Cook to Perfection: Place the casserole uncovered into the preheated oven. Bake for 30 to 35 minutes or until the top is golden brown and the center is fully set, indicating a souffle-like, fluffy texture.
- Finishing Touches: Remove the casserole from the oven and let it rest for at least 10 minutes. This resting period helps the casserole firm up, making it easier to slice and serve without falling apart.
- Serve and Enjoy: Serve the casserole warm, optionally topped with fresh cilantro, avocado slices, or a drizzle of sour cream for added freshness and creaminess to complement the smoky chiles.
Notes
- To roast green chiles, char them over an open flame or under a broiler until the skin blisters, then peel and seed them before using.
- Use a mixture of cheeses for balanced flavor and texture; Monterey Jack provides creaminess while sharp cheddar adds a tangy bite.
- Allow the casserole to cool before slicing to maintain its shape and prevent it from falling apart.
- This casserole can be made a day ahead and reheated gently in the oven.
- For a spicier version, leave some roasted chile seeds or add diced jalapeños to the egg mixture.
