How To Make Chile Relleno Casserole

When preparing this dish, you’re really looking at only 10-15 minutes of prep work. Even though there are some steps, you can be doing some while the others are working.

The first thing we need to do is to roast up the poblanos.

Poblano peppers on a baking sheet.

Place your poblanos on a parchment-lined or aluminum foil-lined baking dish and place them in the oven and broil them. Optionally, if you’re able, roasting these over an open flame works just as well.

You will want to turn them approximately every couple of minutes.

Ground beef with onions browning in a skillet.

While the poblanos are roasting, add the ground beef to a skillet over medium-high heat to start to brown. Add the diced onion.

If you’re seeing a lot of fat coming off of the beef as it is browning, go ahead and drain it off.

We’re looking for a relatively dry mince on the beef, but by all means, break up the meat the way you prefer it.

When the poblanos are sufficiently roasted, remove them from the oven. They should have some good char on them and have blistered skin. They also should be pretty soft.

Roasted poblanos sweating in a plastic bag.

Place the peppers into a plastic bag and let them sweat for 5-10 minutes. This will allow the skin to be removed from the pepper easily. You can also place them in a bowl and cover them with plastic wrap.

Meanwhile, continue to cook the ground beef until browned. Next, add the taco meat spice mixture (or use the taco seasoning packet from the store) and 1/3 cup of water.

Mix to combine well until it’s absorbed and remove from the heat.

When the poblano peppers have sweated sufficiently, remove them. Remove the stems and outer skin from the peppers.

Slice the peppers in half lengthways and remove the seeds. It’s ok if they kind of fall apart on you. No big deal.

Any of the cheddar cheeses, such as sharp cheddar cheese, works just as well.

Next, create a layer of poblanos on a greased 9×13 baking dish. Sprinkle half of the ground beef over the peppers. Then top with half the shredded pepper jack cheese.

Create one more layer following the same steps.

In a medium-sized bowl, add the milk and flour. Whisk well to combine.

Seasoned egg mixture in a mixing bowl.

Next, add the eggs and baking powder, salt, pepper, onion powder, and garlic powder. Whisk this well to combine until no lumps remain.

The chile relleno casserole is done when you see some golden brown goodness, and when you give it a shake, you detect very little jiggle in the center.

Remove from the oven and allow to set up for at least 10 minutes before serving.

When ready to serve, cut into individual portions and serve it up. Garnish with whatever garnish you like with your Latin flavors.

Tips And Variations

  • When putting the roasted poblano peppers into the baking dish, hit them with some salt. This will bring the flavor of that poblano out. Not doing this, you may find that the pepper is rather bland.
  • Mix the flour and milk together first before adding the eggs. If you add the eggs to the flour, you will have lumps.
  • Feel free to omit the ground beef to keep this meal vegetarian. Works great.
  • Add Mexican chorizo instead of ground beef for a variation of flavor.
  • Mix up the cheeses; Monterey jack cheese is great for a slightly milder experience. Cheddar cheese is just as good.
  • We prefer to work with whole green chiles but to speed up the process, you can use canned poblano peppers. Stick with fresh peppers if you can, though.
  • You can substitute poblano chiles for other chile peppers, such as anaheim peppers, or hatch green chiles for a slightly more spicy experience.

    1. Best judgement rules supreme here. If you find you’re running out of room in the pan you decide to use, just make more layers.

  1. Hi Brad!! We had our chef make this today and she has it fully cooked and in the fridge (looks delicious!)- how would you recommend reheating for optimal results? I’d assume in the oven but we don’t want to overcook it! Maybe at a low temp for like 30 mins? Thank you!!5 stars

    1. Hey Kami, gotta say, never tried reheating this entire casserole dish before. BUT, with that said, I’d treat it like most others. I’d reheat at 325, covered with tin foil, until the desired temp is hit in the center. I’d figure that’d take about 30 minutes.

  2. Super easy and delicious weeknight meal. I used ground turkey because that’s what I had. I was surprised how much flavor it had with so few ingredients. The roasted poblano and some kick from taco seasoning were perfect with the fluffy egg mixture.5 stars

  3. I made this recipe exactly, and my family really enjoyed this. I won’t change anything, except maybe increase the number of servings. Delicious!!5 stars

    1. Hey Athena. For meal prep, allow the casserole to cool to room temperature, then cut it into your preferred portion size. Wrap each piece in plastic wrap the aluminum foil, and they’ll keep for about three months.
