What is a Chile Relleno?
Translating to “stuffed chile,” chile relleno is defined by its use of poblano peppers or similar mild chiles, which are roasted to enhance flavor, peeled, and filled—traditionally with cheese. Classic versions are dipped in egg batter and fried, but baked casseroles are a popular, easier alternative.
Key Elements
- Poblano Peppers: Usually roasted, peeled, and deseeded for optimal flavor and texture.
- Cheese Filling: Colby Jack or Cheddar; other cheeses like Monterey Jack or Oaxaca can be used.
- Sauce: Enchilada sauce is common, though tomato-based sauces or mole can also enhance the dish.
- Batter/Custard: Eggs, flour, milk, and baking powder create a light, airy layer in casserole variations.
Ingredients for Chile Relleno Casserole
| Ingredient | Amount | Notes |
|---|---|---|
| Poblano peppers | 8 | Larger peppers preferred; roast and peel |
| Colby Jack cheese sticks or chunks | 8 (1 oz each)/8 oz total | Cut into 1-inch pieces |
| Enchilada sauce | One 10-ounce can | Red or green |
| Eggs | 8 large | For the custard |
| Cheddar cheese | 1 cup grated | For extra richness |
| Whole milk | 1 cup | Adds creaminess |
| All-purpose flour | 3 tablespoons | Binds custard mixture |
| Baking powder | 1/2 teaspoon | Helps lift batter |
Step-by-Step Instructions
- Prepare the Poblano Peppers
- Roast peppers over an open flame or broiler until blackened all over, turning for even char.
- Transfer to a bowl, cover with plastic wrap for 5 minutes to steam; this loosens the skin for peeling.
- Cool, peel off the blistered skin under cold running water, then remove stems and seeds.
- Fill the Peppers
- Place a piece of Colby Jack cheese in each prepared pepper.
- Layer the Casserole
- Pour half of the enchilada sauce in the bottom of an 8-inch square baking dish.
- Add half of the cheese-stuffed peppers, then repeat with remaining sauce and peppers.
- Prepare the Custard Mixture
- Beat eggs until very frothy.
- Whisk in cheddar, milk, flour, and baking powder.
- Gently pour this mixture over the casserole contents.
- Bake
- Bake at 350°F for approximately 1 hour, until set and golden brown on top.
- Rest for 5 minutes before serving.
Tips for the Best Chile Relleno
- Roast peppers thoroughly for easy peeling and a rich, smoky flavor.
- Use cheese that melts well—experiment with Oaxaca, Monterey Jack, or even mozzarella for variation.
- For a spicy kick, consider adding a dash of hot sauce or diced jalapeños to the cheese filling.
- Let casserole rest before serving to help custard set and improve slicing.
Variations
- Traditional Fried Chile Relleno: Instead of baking, dip stuffed and peeled peppers in seasoned flour and whipped egg batter, then fry until golden. Top with tomato sauce.
- Vegetarian Chile Relleno: Replace cheese with beans, mushrooms, or a blend of roasted veggies.
- Protein-Packed: Add cooked shredded chicken, pork, or beef to the cheese filling for a heartier version.
- Green Chile Casserole: Substitute with Anaheim or hatch green chiles for a different flavor profile.
- Breakfast-Style: Add cooked chorizo and serve with eggs for a morning twist.
Serving Suggestions
- Top with chopped cilantro, sliced green onions, or fresh tomato salsa for garnish.
- Serve alongside seasoned beans, rice, and sliced avocado for a complete Mexican meal.
- Pair with tortillas to scoop up every delicious bite.
