Ingredients
  

  • 4-6 slices sourdough French bread
  • 2-3 tbsp butter (softened)
  • 2 cups cheddar cheese (shredded )
  • 2 cups Monterey Jack cheese (shredded )
  • 7 oz green chilies (chopped)
  • 6 eggs
  • 2 cups milk
  • ¼ tsp garlic powder
  • 2 tsp salt
  • ½ tsp pepper
  • 2 tsp paprika
  • 2 tsp dry mustard

Instructions
 

Step 1: Prepare the Bread

  • Cut French bread into ½-inch slices. Butter one side of each slice.

Step 2: Layer the Casserole

  • Arrange buttered slices (butter side down) in a greased 11×7 or 9×12 inch baking dish. Sprinkle half of the cheddar and Monterey Jack cheese over the bread. Top with half of the chopped green chilies.

Step 3: Repeat Layers

  • Add a second layer of bread, then top again with remaining cheese and chilies.

Step 4: Mix the Egg Mixture

  • In a large bowl, beat eggs until well blended. Add milk, garlic powder, salt, pepper, paprika, and dry mustard. Mix well.

Step 5: Combine and Soak

  • Pour egg mixture evenly over the layered bread, cheese, and chilies. Let sit for a few minutes to absorb.

Step 6: Bake the Casserole

  • Bake at 350°F for 45–50 minutes or until the top is lightly browned and center is set.

Step 7: Rest Before Serving

  • Let casserole stand for 10 minutes before cutting into squares.

Tips

  • Add cooked chorizo or breakfast sausage between cheese layers for a heartier version.
  • Use pepper jack cheese instead of Monterey Jack for extra heat.
  • Replace sourdough with brioche or French bread for a softer texture.
  • Add sautéed onions or jalapeños for deeper flavor.
  • Mix in roasted red peppers for color contrast.
  • Substitute evaporated milk for regular milk for a richer custard.
  • Use canned whole green chiles sliced lengthwise for a more traditional “relleno” feel.
  • Assemble the casserole the night before and refrigerate, perfect for brunch.
  • Serve with salsa, sour cream, or guacamole on the side.
