Recipe Tips & Notes
The Peppers. I used poblano peppers here, as they are traditional for chiles rellenos, but you can use Hatch peppers, Anaheim peppers, any larger green peppers that can be roasted.
You can also make this with canned green chilies. If you're looking for a spicier version of this recipe, feel free to bring in a few serrano peppers or habanero peppers to up the heat level.
The Sauce. Try my Homemade enchilada sauce for your base as a time saver.
Or try this Quick and Easy Enchilada Sauce Recipe. It would also be quite tasty with Ranchero Sauce.
Additional Ingredients. Want to make this a fuller meal? Incorporate some shredded chicken, Mexican chorizo, or cooked ground beef or pork for a protein, or add refried beans to round it out.
You'll get a heartier meal this way.

Storage & Leftovers
Store any leftover chile relleno casserole in the refrigerator in a sealed container or covered in plastic wrap or aluminum foil up to 5 days.
