Chile relleno breakfast casserole is a flavorful, baked egg dish inspired by the classic Mexican favorite. Made with roasted green chiles, eggs, and plenty of cheese, this casserole is rich, savory, and perfect for brunch, holidays, or an easy make-ahead breakfast.

  • Total Time: 50 minutes
  • Yield: 6 servings

Ingredients

Chiles and Cheese

  • 1 (7 oz) can whole green chiles, drained and halved
  • 1½ cups shredded Monterey Jack cheese
  • ½ cup shredded cheddar cheese

Egg Mixture

  • 8 large eggs
  • 1 cup milk
  • ¼ cup all-purpose flour
  • ½ teaspoon salt
  • ½ teaspoon black pepper
  • ½ teaspoon garlic powder

Other

  • 1 tablespoon butter or cooking spray (for greasing the dish)

Instructions

  1. Preheat oven and prepare dish: Preheat the oven to 375°F (190°C). Grease an 8×8-inch baking dish with butter or cooking spray to prevent sticking.
  2. Arrange chiles: Evenly place the halved green chiles in the prepared baking dish to form the base of the casserole.
  3. Add cheeses: Sprinkle the shredded Monterey Jack and cheddar cheeses evenly over the arranged chiles to ensure even melting and flavor throughout.
  4. Mix egg batter: In a large bowl, whisk together eggs, milk, flour, salt, black pepper, and garlic powder until the mixture is smooth and well combined.
  5. Pour egg mixture: Carefully pour the egg mixture evenly over the chiles and cheese in the baking dish, allowing it to settle around the ingredients.
  6. Bake the casserole: Place the dish in the preheated oven and bake uncovered for 35–40 minutes until the casserole is set in the center and the top is lightly golden.
  7. Rest and serve: Remove from the oven and let the casserole rest for 5–10 minutes to firm up before slicing and serving.

Notes

  • For extra protein and flavor, add cooked ground sausage or crumbled bacon to the casserole before baking.
  • Using roasted fresh Hatch or Anaheim chiles instead of canned will enhance the depth of flavor.
  • This casserole can be assembled the night before and baked fresh in the morning for easy meal prep.
  • Store any leftover casserole in the refrigerator for up to 4 days; reheat before serving.
