Ingredients for Chile Relleno Casserole
Whipping up this delightful chile relleno casserole is straightforward with these fresh and flavorful ingredients. Each component plays a crucial role in creating the perfect balance of taste and texture.
- Main Ingredients:
- Poblano peppers: 6-8 large, fresh poblanos provide the best smoky flavor and tender texture once roasted. Roasting poblano peppers not only enhances their smoky flavor but also helps with the removal of their tough outer skin, as explained by Texas A&M University’s Dinner Tonight program.
- Monterey Jack cheese: 2 cups, freshly shredded. This cheese offers excellent melt and a creamy texture.
- Cheddar cheese: 1 cup, freshly shredded. It adds a sharper, more robust flavor that complements the poblanos.
- Large eggs: 5 eggs form the base of the custardy topping, binding the casserole together.
- Whole milk: 1 & 1/2 cups. It contributes richness and helps create a smooth, luxurious custard.
- All-purpose flour: 3 tablespoons. This helps bind the egg mixture and gives the casserole its desired structure.
- Baking powder: 1 teaspoon. It provides a light, fluffy rise to the egg custard, ensuring a tender result.
- Seasonings: 1/4 teaspoon each of onion powder, garlic powder, salt, and black pepper are essential for a well-rounded, savory flavor.
- Notes & Substitutions:
- For a time-saving alternative, you can use 3-4 (7oz) cans of drained and seeded green chilies instead of fresh poblanos for your chile relleno casserole.
- Feel free to substitute Monterey Jack and cheddar with other excellent melting cheeses like pepper jack for a kick, or a pre-shredded Mexican blend for convenience.
- While whole milk provides the best richness and texture, 2% milk can also be used if that is what you have on hand.
- Elevate your casserole with delicious add-ins. Cooked ground beef, shredded chicken, savory chorizo, sweet corn, or sautéed mushrooms all make fantastic additions.
Equipment Needed
Gathering your tools before you start makes the cooking process smooth and enjoyable. You will need just a few basic kitchen items for this recipe.
- Baking sheet: Essential for roasting the poblano peppers evenly.
- Aluminum foil: For lining the baking sheet and aiding in easy cleanup.
- Plastic bag: Use a resealable plastic bag for steaming the hot peppers.
- 3-quart baking dish: The ideal size for assembling and baking your casserole layers.
- Medium mixing bowl: Perfect for whisking together the egg custard mixture.

How to Make Chile Relleno Casserole
Creating this delicious chile relleno casserole is a simple process, broken down into easy-to-follow steps. Follow these instructions closely for a perfect result every time.
- Roast Peppers: Begin by preheating your oven broiler and positioning the rack about 6 inches from the heat source. Line a sturdy baking sheet with aluminum foil for easier cleanup. Arrange the poblano peppers on the prepared baking sheet and roast them for approximately 10-15 minutes. Use tongs to turn them occasionally, ensuring the skins blacken and char evenly on all sides. This charring step is crucial for developing deep flavor.
- Steam & Peel: Immediately transfer the hot roasted peppers into a plastic bag, sealing it tightly. Allow the peppers to steam in the bag for about 10 minutes as they cool. The steam helps loosen the skins, making them much easier to peel. Once the peppers are cool enough to handle comfortably, carefully peel off the loosened skin.
- Prepare Peppers: After peeling, take a moment to prepare the chiles properly. Cut off the stems, then carefully open each pepper to remove all the seeds and any tough membranes. Gently flatten the chiles to create nice, even layers for your casserole.
- Preheat Oven & Grease Dish: Preheat your oven to 350 degrees F (175°C). Lightly coat a 3-quart baking dish with a nonstick cooking spray. This prevents sticking and ensures easy serving of your finished casserole.
- Layer Casserole: Lay half of the prepared roasted chiles evenly in the bottom of the greased baking dish, forming a single layer. Sprinkle 1 cup of the shredded Monterey Jack cheese and 1/2 cup of the shredded cheddar cheese evenly over the chiles. Repeat these layers once more with the remaining chiles and cheeses to build your delicious chile relleno casserole.
- Whisk Egg Mixture: In a medium-sized mixing bowl, whisk together the five large eggs, 1 & 1/2 cups of whole milk, 3 tablespoons of all-purpose flour, and 1 teaspoon of baking powder. Add the 1/4 teaspoon each of onion powder, garlic powder, salt, and black pepper. Whisk diligently until all the ingredients are thoroughly combined and there are no lumps of flour visible.
- Pour & Bake: Carefully pour the whisked egg mixture evenly over the cheese and chile layers in the baking dish. Gently tap the dish a couple of times on the counter to help the liquid settle. Place the baking dish into the preheated oven and bake for about 45 minutes. The casserole is ready when it is beautifully puffed up in the center, the eggs are fully set, and the edges are golden brown.
- Cool & Serve: Once baked, remove the chile relleno casserole from the oven. Let it stand and cool for 5-10 minutes before cutting into squares. This resting period allows the casserole to set properly, making it easier to slice and serve cleanly. Serve with a dollop of sour cream, a little salsa, and some freshly chopped cilantro for an extra burst of flavor. Enjoy!
Pro Tips for the Best Chile Relleno Casserole
Achieve culinary perfection with these helpful tips for your next chile relleno casserole.
- Perfectly Roasted Peppers: Ensure you char the poblanos well for deep, smoky flavor. Proper steaming in a bag is key for easy skin removal, preventing tough bits in your casserole.
- Fluffy Eggs: Whisk the egg mixture thoroughly to incorporate air. This creates a light, airy, and fluffy custard topping for your casserole, not a dense one.
- Avoid Watery Casserole: If using canned chilies, drain them exceptionally well. Additionally, ensure you do not undercook the casserole, as this can result in a runny center.
- Freshly Shredded Cheese: Always shred your own cheese from a block. Freshly shredded cheese melts much better and tastes far superior to pre-shredded varieties. The presence of anti-caking agents in pre-shredded cheese can hinder its ability to melt smoothly and cohesively, as noted by culinary experts on the impact of anti-caking agents on cheese melting.
- Seasoning Adjustments: Taste the egg mixture before pouring it over the layers. This allows you to adjust the salt, pepper, or other seasonings to perfectly match your preference.
Serving Suggestions, Storage & Variations
This versatile chile relleno casserole tastes fantastic on its own, but it also pairs wonderfully with a variety of toppings and sides. It’s also incredibly easy to store and adapt!
- Serving Ideas:

- Serve alongside warm Spanish rice, fluffy white rice, or creamy refried beans for a complete and satisfying meal.
- Make Ahead:
