  • 1/2 cup diced onions
  • 1/2 cup sliced black olives
  • 1/2 cup chopped fresh cilantro
  • 1 cup diced tomatoes

Instructions

Step 1: Prepare the Chiles

  1. If using fresh poblanos, roast them over an open flame or under a broiler until the skin is charred.
  2. Transfer to a bowl, cover, and let them steam for 10 minutes.
  3. Peel off the skin, remove the seeds, and pat dry with a paper towel.

Step 2: Preheat the Oven & Prepare the Dish

  1. Preheat your oven to 375°F (190°C).
  2. Grease a 9×13-inch baking dish.

Step 3: Assemble the Layers

  1. Lay half of the roasted chilies in the bottom of the dish.
  2. Sprinkle with half of the shredded cheeses.
  3. If using meat or other add-ins, spread them evenly over the cheese.
  4. Repeat with the remaining chilies and cheese.

Step 4: Prepare the Egg Mixture

  1. In a large mixing bowl, whisk together eggs, milk, flour, baking powder, and seasonings until smooth.
  2. Pour the mixture evenly over the casserole layers.

Step 5: Bake the Casserole

  1. Place the dish in the oven and bake for 35-40 minutes, or until the center is set and the top is golden brown.
  2. Let it rest for 5-10 minutes before slicing.

Step 6: Serve & Enjoy!

  • Garnish with fresh cilantro, diced tomatoes, or avocado slices.
  • Serve warm with salsa, sour cream, or guacamole.

Notes

Use Freshly Roasted Peppers – If possible, use fresh poblanos for the best flavor.
Let It Rest Before Slicing – This allows the casserole to set properly.
Make It Spicy – Add diced jalapeños or hot sauce for an extra kick.
Use a Mix of Cheeses – Combining cheeses enhances the depth of flavor.
Make Ahead Friendly – Assemble it the night before and bake the next day!
