Ingredients

Scale

Vegetables and Toppings

  • 4 pieces Fresh Poblano Peppers (Choose firm ones for best results.)
  • 1 medium Onion (Yellow or white onions work best.)
  • 1 cup Salsa (Zesty addition.)
  • 1 large Avocado (Luscious contrast.)

Egg Mixture

  • 6 large Eggs (Essential protein.)
  • 1 cup Whole Milk (Can swap for non-dairy alternatives.)
  • 1 teaspoon Garlic Powder (Boosts flavor.)
  • Salt to taste (Essential for balancing flavors.)
  • Pepper to taste (Adjust according to your taste.)

Cheese

  • 2 cups Shredded Cheese (Blend of Monterey Jack and Cheddar; try Pepper Jack for extra spice.)


Instructions

  1. Preheat the Oven: Preheat your oven to 375°F (190°C) and grease a baking dish with cooking spray or butter to prevent sticking.
  2. Roast the Poblanos: Place the fresh poblano peppers on a baking sheet and roast them in the oven for about 20 minutes, turning occasionally until they are charred and blistered. This develops their flavor and softens them.
  3. Prepare Egg Mixture: In a large mixing bowl, whisk together the eggs and whole milk until frothy. Add garlic powder, salt, and pepper to your taste to season the mixture.
  4. Assemble the Casserole: Chop the roasted poblano peppers and layer them evenly in the greased baking dish. Pour the seasoned egg mixture over the peppers, then sprinkle the shredded cheese evenly on top.
  5. Bake: Bake the assembled casserole for 30 to 35 minutes, or until the eggs are fully set and the cheese on top turns golden brown and bubbly.
  6. Cool and Serve: Allow the casserole to cool for about 5 to 10 minutes to set properly. Serve with a dollop of salsa or slices of fresh avocado for a creamy and zesty finish.

Notes

  • For extra spice, substitute the Monterey Jack and Cheddar cheese blend with Pepper Jack cheese.
  • Whole milk can be replaced with non-dairy alternatives such as almond or oat milk for a dairy-free version.
  • Make sure to char the poblanos well for the best smoky flavor.
  • This casserole can be prepared the night before; just refrigerate and bake in the morning for a quick breakfast.
  • Add diced onions into the egg mixture if you prefer an extra layer of flavor and texture.
