I love this recipe because it captures the classic flavors of chile rellenos in an easier, oven-baked form. The roasted poblano peppers bring a mild heat and smoky flavor that pairs beautifully with the melted cheese.
I also enjoy how the egg mixture bakes into a light and fluffy layer that holds the casserole together. It creates a texture that feels both hearty and satisfying.
Another reason I like making this dish is how versatile it is. I can serve it for breakfast, brunch, lunch, or dinner, and it pairs well with many sides like rice, beans, or a fresh salad.
Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
4–6 poblano peppers 1 tablespoon olive oil Salt and pepper, to taste 2 cups shredded Monterey Jack cheese
4 large eggs 1/2 cup skim milk 1/3 cup all-purpose flour 1/2 teaspoon baking powder 1/2 teaspoon paprika 1/2 teaspoon chili powder 1/2 teaspoon garlic powder 1/2 teaspoon salt 1/4 teaspoon black pepper
Directions
I begin by preheating the oven to 425°F.
I place the poblano peppers on a baking sheet, drizzle them with olive oil, and sprinkle them with salt and pepper.
I roast the peppers for about 25 minutes until they become blistered and slightly charred.
I transfer the hot peppers to a large bowl and cover them with plastic wrap so they can steam for about 15 minutes.
Once they are cool enough to handle, I peel off the skins, remove the seeds, and cut off the stems.
I reduce the oven temperature to 350°F and spray a 9-inch baking dish with non-stick cooking spray.
I arrange half of the roasted peppers in a single layer in the baking dish and sprinkle half of the shredded Monterey Jack cheese over them.
I repeat the layers with the remaining peppers and cheese.
In a medium bowl, I whisk together the eggs, milk, flour, baking powder, paprika, chili powder, garlic powder, salt, and black pepper until smooth.
I pour the egg mixture evenly over the layered peppers and cheese.
I bake the casserole for about 30 minutes until the eggs are puffed, the edges are golden, and the center is set.
I let the casserole rest for about 5 minutes before slicing and serving.
Servings and timing
This recipe makes about 6 servings.
Preparation time: about 25 minutes Cooking time: about 30 minutes
Total time: approximately 55 minutes.
Variations
I sometimes add cooked ground beef or shredded chicken between the layers of peppers and cheese when I want a heartier version.
For extra flavor, I occasionally mix a small amount of diced green chilies or chopped jalapeños into the egg mixture.
If I want a different cheese profile, I replace some of the Monterey Jack with cheddar or pepper jack for added sharpness or heat.
storage/reheating
I allow the casserole to cool completely before storing it in an airtight container in the refrigerator for up to 4 days.
To reheat, I warm individual portions in the microwave for about 1 to 2 minutes or place the casserole in the oven at 300°F until heated through.
For longer storage, I freeze the casserole in a freezer-safe container for up to 2 months. I thaw it overnight in the refrigerator before reheating.
FAQs

I often replace Monterey Jack with cheddar, pepper jack, or a Mexican cheese blend depending on the flavor I want.
How do I know when the casserole is fully baked?
I check that the center is set and the edges are lightly golden. A knife inserted in the middle should come out mostly clean.
