What Is Poblano Casserole?

Poblano Casserole is a deconstructed version of chile rellenos. Instead of stuffing and frying each pepper, everything is layered into a baking dish and cooked together.

The roasted poblano peppers bring a mild heat and smoky depth, while the cheese and egg mixture create a soft, almost custard-like texture. It’s hearty, flavorful, and incredibly easy to make.

Instructions

Step 1: Roast the Poblanos

Place poblano peppers under a broiler or over an open flame until the skins are charred. Transfer to a bowl, cover, and let steam for 10 minutes. Peel off the skins, remove seeds, and slice into strips.

Preheat your oven to 180°C (350°F). Lightly grease a baking dish.

Step 3: Layer the Ingredients

Spread half of the roasted poblano strips in the dish. Sprinkle half the cheese over the top. Repeat with remaining peppers and cheese.

Step 4: Prepare the Batter

In a bowl, whisk together eggs, milk, flour, baking powder, salt, and pepper until smooth.

Step 5: Assemble

Pour the egg mixture evenly over the layered peppers and cheese.

Step 6: Bake

Bake for 35–40 minutes, or until the casserole is set and golden on top.

Step 7: Cool Slightly

Let it rest for 5–10 minutes before slicing.

Step 8: Garnish and Serve

Top with cilantro, sour cream, or salsa and serve warm.
