Preheat the oven to 425°F, and line a baking sheet with aluminum foil. Place the peppers on the baking sheet and drizzle with oil. Rub the oil evenly over peppers then transfer the pan to the oven.
8 poblano peppers, 1 tablespoon canola oil
Cook the poblanos for 25 to 30 minutes, turning occasionally. The skins should blister and blacken.
While the peppers roast, make the filling. In a medium bowl or measuring cup, whisk together the eggs and milk. Add the flour, baking powder, and salt. Set aside.
5 large eggs, ½ cup milk, ½ cup all-purpose flour, 1 teaspoon baking powder, ½ teaspoon salt
Remove the peppers from the oven, and reduce the oven to 350°F. Allow the peppers to cool until they’re easy to handle, then peel away the skins and discard. Cut off the stems and tops, and remove the seeds and membranes.
Place a 1 ounce piece of cheese into each poblano. Lay the poblanos in a single layer in an 11x7-inch or 9x13-inch baking dish. Pour the egg mixture over the peppers. Top with remaining 4 ounces of shredded Monterey jack cheese.
8 ounces Monterey jack cheese, 4 ounces Monterey jack cheese
Bake for 30 minutes or until the top is golden brown and the center is set. Remove from the oven and serve with sour cream or salsa if desired.
Notes
The calories listed are an approximation based on the ingredients in the recipe card and a serving size of ⅛ of the chile relleno casserole. Actual calories will vary.
Roast the peppers however you'd like (grill, broiler, etc.). After they've blistered nicely, drop them into a paper bag to steam until they're easy to handle. Once they've cooled a bit, carefully peel and remove the seeds.
