Preparing Chile Relleno Casserole
If you’re looking for a delicious dish that can impress your friends or family, the chile relleno casserole is a fantastic option. This comforting meal combines smoky poblano peppers, savory ground beef, and a fluffy egg topping that will make any occasion feel special. Let’s break down how to prepare this delicious casserole from start to finish.
Roast the Poblano Peppers
The first step in making your chile relleno casserole is roasting the poblano peppers. This step is crucial as it adds a smoky flavor that will elevate the dish.
- Preheat your oven: Set your oven to broil and position a rack in the upper third (about 6 inches from the heat).
- Prepare the baking sheet: Line a large rimmed baking sheet with aluminum foil.
- Roast the peppers: Arrange the whole poblano peppers on your baking sheet and broil for about 5 minutes until the skins blister and blacken. Flip the peppers and continue broiling for another 5 to 6 minutes.
- Cover and cool: Using tongs, place the roasted peppers in a bowl and cover them with plastic wrap. Let them rest for about 15 minutes. Afterward, peel off the charred skins, remove the stems, and deseed the peppers. Set these aside for the next steps.
Cook the Ground Beef Filling
Now that your peppers are ready, it’s time to create a flavorful filling.
- Heat the skillet: In a large skillet, cook 1 pound of 90% lean ground beef along with ¾ cup diced yellow onion over medium heat. Break the beef apart with a spatula until it’s no longer pink.
- Season well: Drain any excess grease, then add 1 teaspoon minced garlic, 1 ½ teaspoons ground cumin, 1 teaspoon salt, ½ teaspoon black pepper, and optional red pepper flakes. Stir everything together and cook for about a minute until fragrant.
Make the Egg Mixture
The egg mixture is what ties this casserole together.
- Whisk together: In a separate bowl, whisk together 5 large eggs with 1 ½ cups of whole milk. Gradually add ⅓ cup of flour and 1 teaspoon of baking powder, mixing until mostly smooth. This will create a light, fluffy texture that complements the other layers.
Assemble the Casserole Layers
Assembling your chile relleno casserole is the fun part!
- Prep the baking dish: Spray a 9 x 13-inch baking dish with nonstick cooking spray.
- Layer it up: Start with half of the roasted peppers laid out in a single layer. Follow this with half of your cooked beef mixture, and sprinkle ¾ cup each of shredded cheddar and Monterey Jack cheese. Repeat with the remaining beef and peppers, then top with the rest of the cheese.
- Final touch: Slowly pour the egg mixture over all the layers, ensuring even distribution.
Bake Until Golden and Puffy
- Cover and bake: Start baking your casserole by covering it with aluminum foil. Bake for 30 minutes, then remove the foil and bake for an additional 14 to 16 minutes until it’s golden brown and puffy around the edges. Let the casserole cool for about 5 minutes before serving.
Garnish with some fresh cilantro if desired, and enjoy this delightful dish with salsa or sour cream for that extra zing!

FAQs about Chile Relleno Casserole
Can I use canned chilies instead of poblano peppers?
Absolutely! If you're short on time or simply looking for a convenient option, canned fire-roasted green chiles are a fantastic substitute. Brands like Ortega and Hatch offer quality canned chiles that can be found in the Mexican foods section of most grocery stores. You’ll need about 4 to 5 (7-ounce) cans for the layers in your casserole. Just pat them dry and pull them apart for an easy fit in your baking dish.
How to adjust the spice level in the casserole?
Spice levels can easily be tweaked to match your taste! If you prefer a milder version of chile relleno casserole, omit the red pepper flakes altogether. For a kick, add more red pepper flakes or even diced jalapeños to the meat mixture. Don’t hesitate to sample your filling before baking—it’s the best way to ensure it’s just right.
What is the best way to store leftovers?
To keep your chile relleno casserole fresh, transfer any leftovers to an airtight container. Refrigerate for up to 3 days. When you’re ready to enjoy the leftovers, simply reheat individual portions in the microwave until warmed through. It’s great for quick meals or snacks!
