Chile Relleno Casserole is a delicious dish of roasted poblano peppers baked in a cheesy egg mixture. This recipe is the ultimate comfort food!

Relleno (pronounced reh-YEH-no) is a pepper stuffed with cheese, dipped in egg batter, and fried. This recipe deconstructs the relleno and bakes it all in one dish!

Because this dish is eggy, but not TOO eggy, it is great as either a dinner dish OR a breakfast dish!

If you love Southwest cuisine, you are going to love this twist on a classic Mexican dish. Poblano peppers are very mild, so anyone will be able to enjoy this Mexican casserole

How to Make Chile Relleno Casserole

You will be sitting at the oven waiting for the timer to go off when the aroma of roasted poblanos starts to fill the house. This recipe can take some time, especially if you are not well versed in peeling peppers. Read my tips below on how to prep peppers ahead of time.

  1. Preheat the oven to 400 degrees Fahrenheit and line a large baking pan with aluminum foil or parchment paper.
  2. Remove the stems and slice the peppers on one side lengthwise, leaving the peppers intact, and then remove the seeds. Place the Poblano peppers on the baking pan evenly spaced then drizzle on the olive oil. Use your hands to coat them well.
  3. Bake for 20 minutes. Flip the peppers over and bake for 10 more minutes or until the tops have charred a bit.
  4. In the meantime, whisk together the eggs, milk, flour, salt, cumin, paprika and baking powder in a large bowl then set aside.
  5. Once the peppers are done, reduce the oven heat to 350 degrees Fahrenheit. Let the peppers cool until you can safely handle them then remove the skin and slice each pepper in thirds lengthwise.
  6. Pour 1/3 of the egg mixture into a 9 by 13-inch baking pan or a casserole dish then add ½ of the peppers on top along with 1/3 of the cheese sprinkled on top.
  7. Pour half of the remaining egg mixture on top followed by the remaining pepper slices.
  8. Pour on the remaining egg mixture followed by the remaining cheese and cover loosely with aluminum foil then bake for 20 minutes.
  9. Remove the foil and bake again for 15-20 minutes or until the center no longer jiggles. Slice and serve with freshly chopped cilantro for garnish if desired. Note: the casserole will deflate after it comes out of the oven.

Recipe Tips

  • Roast the peppers ahead of time. Peeling the peppers can be a tedious task, especially if it’s your first time. You can roast and peel the poblano peppers, and refrigerate until you are ready to bake the dish.
  • Make sure the peppers are covered with oil. Fully coated peppers will roast more evenly. You want the skin to have a wrinkly appearance. This will make it so much easier to peel.
  • Use gloves to peel the peppers. As with all peppers, handle them with care. Even though poblanos are considered mild peppers, they can still irritate your soft tissues (nose and eyes). Using gloves keeps the pepper from getting on your fingers.

Do I Have to Peel the Poblano Peppers?

When you roast poblano peppers, the skin becomes papery and tough to eat. While you should peel them for the best experience, eating the skin will not harm you. Leaving the skin on could ruin the taste of the casserole. It is okay if you leave a little on, as it can be difficult to get all of the skin off.

Storage Instructions

This casserole can be stored in an airtight container in the fridge for up to three days.

Variations

For a more flavorful and spicier dish, try roasted Hatch green chile. These New Mexico peppers are seasonal and can be hard to find if you live in other parts of the country, but they are soooo good. Green chile can be super spicy but is loaded with flavor. The canned green chile in the grocery store has nothing on fresh roasted pepper. It is addicting!

What to Serve with Poblano Pepper Casserole

    I’m in the process of making this…….AGAIN…..for the third time :) It’s super easy and I crank my gas grill up and roast the peppers at 500 🔥 The only things I’ve changed is I use smoked paprika (addicted to the smokiness) and I add quesadilla seasoning when cooking ground beef before adding it to the casserole. Then I serve it with red enchilada sauce on top. I’m drooling as I think about it! LOL ! THANK YOU for sharing this fantastic recipe!

    I love this recipe because it molds together my two homes - Wisconsin and New Mexico.

    This is by far easiest recipe I have tried without having to make the actual Chile rellenos. My husband loved and says he would prefer to eat like this all the time instead of me going through tedious old_fashioned way! Thanks for sharing short cut.

    Can breast meat be shredded and added to this? Any adjustments needed?

    @Mary, ooh that sounds good! If you are adding cooked, shredded chicken, then I do not think you need to make any adjustments as far as cooking time.

    Why evaporated milk?? Why not regular milk?
