Why You’ll Love Chile Relleno Casserole Recipe
This casserole brings together the bold flavors of roasted poblano peppers and creamy cheese in a simple baked dish that is both satisfying and easy to make.
First, it simplifies a traditional recipe. Classic chile rellenos often require stuffing, battering, and frying the peppers. This casserole version eliminates those steps while still delivering the same delicious flavors.
Second, it’s incredibly cheesy and comforting. The layers of Monterey Jack melt beautifully between the peppers, creating a rich and creamy texture in every bite.
Another reason to love this dish is its versatility. It can be served for breakfast, brunch, lunch, or dinner, and it pairs well with toppings like sour cream, salsa, or fresh cilantro.
Finally, it’s perfect for feeding a group. With six generous servings, this recipe is great for family meals, gatherings, or meal prep.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
1 pound poblano peppers (about 4–5 medium peppers)
4 cups shredded Monterey Jack cheese (divided)
6 large eggs
1 cup whole milk
1/3 cup all-purpose flour
1 teaspoon baking powder
1/2 teaspoon garlic powder
1/2 teaspoon onion powder
1/2 teaspoon dried oregano
1/2 teaspoon kosher salt
1/4 teaspoon black pepper
Directions
Begin by preheating your oven’s broiler and positioning the rack about 6 inches from the heat source. Line a baking sheet with aluminum foil and place the poblano peppers on top. Broil them for about 5 to 7 minutes per side, turning occasionally, until the skins are blackened and blistered.
Transfer the roasted peppers to a bowl and cover it tightly with plastic wrap or foil. Allow the peppers to steam for about 10 minutes. This helps loosen the skins and makes them easier to peel. Once cool enough to handle, gently peel off the charred skin, cut a slit down one side of each pepper, and remove the seeds and stems.
Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish with cooking spray or olive oil.
Arrange half of the roasted peppers in a single layer across the bottom of the casserole dish. Sprinkle 2 cups of shredded Monterey Jack cheese evenly over the peppers. Repeat the layering process with the remaining peppers and the remaining 2 cups of cheese.
In a medium bowl, whisk together the eggs, whole milk, flour, baking powder, garlic powder, onion powder, dried oregano, kosher salt, and black pepper. Continue whisking until the mixture is smooth and fully combined.
Pour the egg mixture evenly over the layered peppers and cheese, making sure it seeps into all the gaps and covers the surface.
Place the casserole into the preheated oven and bake for 40 to 45 minutes, or until the center is set and the edges turn golden brown.
Remove the casserole from the oven and allow it to rest for about 10 minutes before slicing. This helps the layers set properly. Serve warm with sour cream, salsa, or chopped cilantro if desired.
Servings and timing
This recipe makes approximately 6 servings.
Preparation time takes about 15 minutes, including roasting and preparing the peppers. Baking the casserole requires about 40 to 45 minutes. After baking, the casserole should rest for 10 minutes before serving.
Total time from start to finish is about 45 minutes.
Variations
One delicious variation is to add cooked ground beef or shredded chicken between the layers of peppers and cheese. This creates a heartier casserole that works well for dinner.
For a spicier version, include diced jalapeños or use a mix of poblano and Anaheim peppers.
You can also experiment with different cheeses. Cheddar, pepper jack, or a Mexican cheese blend can add different flavor profiles to the dish.
For a lighter version, substitute part of the Monterey Jack with reduced-fat cheese and use low-fat milk.
Vegetable lovers can add sautéed onions, mushrooms, or corn between the layers to add texture and flavor.
