Tips for making Chile Relleno Casserole

  • Make sure the chiles are well-roasted in the oven. Don’t worry about the charred skin, it gets removed but leaves behind a ton of flavor.
  • Use an airtight lid or plastic wrap to steam the peppers. Letting the peppers steam in the container until they are almost cool will not only tenderize the peppers, but it will make it very easy to remove the skin.
  • Add extra toppings to the casserole after it is cooked. Providing a variety of toppings for people to dress their own casserole can be a fun and flavorful way to enjoy dinner!
