What Is Chili Relleno?

An authentic Chili Relleno is a chili pepper stuffed with cheese and sometimes with meat. It’s usually fried or grilled.

I really love Chili Relleno, but it’s time-consuming. That’s why I really enjoy this casserole. It might take 50 minutes to bake, but the prep is really simple.

Recipe Ingredients

Here’s what I put in my casserole:

  • Shredded Cheese – I used sharp cheddar because it has the best flavor. You can use any combination of cheeses for it. I also use Monterey Jack to make it nice and cheesy.
  • Butter – to help keep the casserole from sticking to the baking dish.
  • Eggs – The egg-size doesn’t matter. You just need 3 eggs of any size.
  • Milk – If you can’t have cow’s milk, you can use almond milk instead.
  • Bisquick – If you are on a gluten-free diet you can use a gluten-free substitute.
  • Chilies – I used Ortega whole and diced green chilies. The canned ones have a better texture and last longer on the shelf.

How to Make Chili Relleno Casserole

This is such an easy recipe to make. The prep work is a breeze. You just mix up the ingredients and then layer them in the casserole dish. Here are the recipe steps:

  1. Combine Cheddar and Monterey Jack cheeses in a bowl.
  2. Spread melted butter in 13 x 9-inch casserole dish.
  3. Lay whole chilies on top of the melted butter. Sprinkle two-thirds of the cheese on the chilies.
  4. Mix the milk, eggs, and Bisquick until smooth.
  5. Stir in diced chilies and pour the mixture over the cheese.
  6. Sprinkle the remaining cheese on top.
  7. Bake at 325 degrees for 45 minutes.

Does Relleno have meat?

The main stuffing for the chili pepper is cheese. It is optional to add meat such as ground beef, pork, or chicken.

Can you freeze Chili Relleno Casserole?

Yes, this makes an excellent freezer meal. Before you bake it, seal it and put it in the freezer. Label it with the date. It will last about 3 months in the freezer.

When you are ready to bake it, take it out of the freezer the night before and let it thaw in the refrigerator. Then, bake it like normal.

    Delicious, quick and easy side dish to put together. Heading back to the store to stock up on fresh Hatch chili while still in season.

    This is soooo good. I add powdered parmesan, cilantro, and smoked paprika over top before baking for pretty color and extra yum flavor!

    I make this all the time. Especially for get together’s. l also use pepper jack cheese with the cheddar because I like it more spicy than most ! 😋😋😋

    I’m probably missing something very obvious here, but I’m not seeing in the recipe how many relleno chili’s are used?

    You posted nutritional info but no serving size so it’s hard to work this into any kind of plan where you’re tracking calories, carbs, etc…
