Growing up in Southern California we had the privilege of enjoying real Mexican food, real Chile Relleno’s.
A family that we helped out on occasion would make and bring us the most incredible chiles rellenos, but they are a decent amount of work and we’re just trying to get breakfast or dinner on the table some nights — amiright?
Fresh Tip
- At times, I’ve had a hard time finding whole roasted chiles. So I modified and used 2-3 (4 oz) cans of diced green chiles instead. Just place them in the dish, with diced chunks of cheese or shredded cheese, pour the egg batter and bake. Turned out great!
What is the difference between a Chili, Chilli, and Chile?
I have always thought of “chili” as the ground beef based stew we make in the fall and wintertime, and Chile as something with peppers, turns out, I am not all that wrong. In fact, depending on where you live, just about any variation goes! I don’t care how you spell it — just make it! Your family will thank you!
The difference betweenchili,chilli, andchile, is usually a matter of location. In American English, “chili” is the most common spelling for the spicy peppers as well as the stew and hotdog topping. In British English the preferred spelling is “chilli.” In Spanish speaking countries and regions of the US, “chile” is the most common variant.
Key Ingredients for New Mexico Chile Relleno Casserole Recipe
- Whole roasted green chiles | I use canned, but home roasted fresh chiles is great (see tip for how to roast below). May also substitute chopped green chiles as well.
- Monterey Jack Cheese | Slice into sticks! Can also try Pepper Jack cheese, regular or your favorite cheddar cheeses, also try Cotijo.
- Eggs | I always use large eggs in my cooking and baking
- All-purpose flour | May substitute with a good 1-1 all purpose gluten-free flour.
- Milk | We use whole milk at home, but you can substitute whatever you normally use.
- Extra cheese grated for sprinkling on top
How do you make Chili Relleno Casserole?
Why is this easy chile relleno recipe so great, because it’s made using canned whole roasted chile peppers.
No roasting, sweating and pulling skins off here, though you are certainly welcome to do so, probably taste even better!
Step 1 | Prep chiles
Rinse the peppers in cold water and then carefully scrape the seeds out, the seeds are where the heat is. If you like the heat, by all means keep them inside! I would say that Hatch Green chiles are typically a mild- medium heat pepper, but you can find hotter versions too.
Use a paper towel to remove some of the extra moisture from the peppers. Spray a 9×9 inch casserole dish with a little spray oil.
Step 2 | Stuff Chile Rellenos
Slice cheese block into sticks and carefully stuff them into the chiles laying in a single layer in the casserole dish.
My favorite cheese for authentic chile rellenos is Monetery Jack cheese – it melts so beautifully, but you can use cheddar, pepper jack or any deliciously melting cheese, or try salty Cotija Mexican cheese.
If the pepper splits, don’t worry about it, just roll it together as best you can and lay it in a lightly greased (spray oil works great here) pan. Tucked them nice and close together.
Step 3 | Make Egg Mixture
In a medium bowl add eggs and using a fork or whisk, beat until smooth. Add regular or gluten-free flour to the mixture, milk and salt and pepper, whisking until smooth.
Pour egg mixture over the top of the cheese stuffed chiles and top with a little grated cheese and bake.
Step 3 | Bake New Mexico Chile Relleno Casserole Recipe
All you do now, is place that casserole dish in the preheated 350 degree F oven and bake between 60-90 minutes, until it’s golden, bubbly, puffed and set.
Frequently Asked Questions
Are Chile Rellenos Spicy?
This dish, made with canned chile peppers is very mild. I prefer roasted Hatch Green Chile’s which I can purchase in our local grocery store, they have delicious flavor but are still very mild, even for spice wimps like me!
If you want to kick up the spice in your dish, try using pepper jack cheese, adding a few (or a lot) of shakes of Tabasco or Cholula sauce to the milk and egg mixture.
Plus Hatch chiles are from New Mexico, making this a truly authentic New Mexico chile relleno casserole recipe.
Can I Make Chile Relleno Casserole Ahead of Time?
Yes! Assemble the chiles and cheese, mix the egg and milk mixture and pour over the chiles, cover and refrigerate until ready to bake.
Set on counter, allowing to come to room temperature 20-30 minutes prior to baking. They may be baked ahead of time, but you will not achieve the same fluffy rise as with the first baking.
What is chile relleno batter made of?
Traditional chile relleno batter is made from eggs, flour and milk. The egg yolks are separated, whipping the whites and mixing the two together. The difference between this easy chile relleno casserole and traditional chile rellenos is the peppers are usually dipped in a frothy egg batter and deep frying until golden and hot.
Can I use other chile peppers for New Mexico Chile Relleno Casserole?
Absolutely! If you want to roast your own peppers, try using Poblano peppers or Anaheim peppers (a little spicier) but they will hold up well in the chile relleno dish.
How to Roast your Own Chile Peppers
Start the process by washing and drying your chile peppers of choice.
- Oven | Place peppers on baking sheet brushed with a little olive oil and roast in a 425 degree oven for 15-20 minutes, turn and roast another 15-20 minutes until they are soft. Steam as directed below.
- Broil | Place peppers on baking sheet brushed with a little olive oil, with rack 3-5 inches from the broiler, broil for about 20 minutes total, turning a quarter turn every 5 minutes. Until charred and peppers are soft. Steam as directed.
- Stovetop | If you have a gas stovetop this is my preferred method for just a few peppers. Place washed and dried peppers directly over the medium gas flame, turning about every 5 minutes, until the entire pepper is charred. Doing it this way imparts the most smokey flavor into the pepper. Steam as directed below.
- Grill or Grill Pan | With the grill heated to medium, place washed and dried peppers directly on grill or grill pan, turning every 5-10 minutes until peppers are soft and completely charred. Steam as directed.
- How to Steam Charred Peppers | Once peppers have been charred, place hot peppers in an airtight baggie for 10-15 minutes. Or on a cutting board and invert a glass bowl over the top of the hot peppers. Once they steamed, gently and carefully remove the charred skin and throw away (a little messy) and then remove stems and carefully remove seeds.
Why are they called Hatch Chiles
Hatch Green Chiles are a specialty chile developed and grown in New Mexico. They are one of my favorite chiles, as they are a bit more mild, but still have loads of flavor.
Variations & Substitutions
- Roast your Own Peppers | You can easily roast your fresh peppers. Wash peppers and pat them dry with paper towels. Place peppers over an open flame, turning occasionally, until the pepper is blackened and charred all over. Once charred, place peppers in plastic bags and seal for about 10 minutes, this sweats the char off and softens the peppers, keeping the roasted flavor inside the chile pepper. Once 10 minutes are up, gently peel away the charred portion and discard. Use peppers are you would in any recipe. Fresh roasted pepper are divine!
- Instead of stuffing the peppers, layer them on the bottom of the dish, then add cubes or shredded cheeses to the top, then pour the egg flour mixture over the top.
- Dairy-Free Chile Rellenos | I’ve never tried this, but replace the cheese and the milk with your favorite plant-based cheese and milk.
Storage
Make Ahead | You can assemble this easy casserole the night before. Cover and while oven preheats, remove and let come to room temperature. Bake as directed.
Refrigerate | Once baked, cool completely then store in airtight container in fridge up to 5 days.
Freeze | Freeze baked and cooled chile rellenos casserole wrapped first in plastic wrap, then wrapped in foil and if possible sealed in an airtight baggie. Freeze up to 3 months.
Reheat | To reheat from frozen, allow to thaw overnight in fridge, then heat in 300 degree F oven for 30-40 minutes covered, until bubbly. To reheat from fridge, place a piece on a microwave safe plate and heat in 30-60 second bursts until hot. Or place in oven at 350 until warmed through.
