Baked Chile Relleno Recipe

I originally had this dish when a friend invited several of us over for brunch, it is the best brunch recipe!

I asked her for it on the spot and I have been making it ever since! Make it ahead, pop it in the oven and shazam when your guests arrive, out it comes, piping hot, dripping with melted, stringy cheese!

I grew up in Southern California with real Mexican food, real Chile Relleno’s, we had a family we helped out growing up that would make the most incredible rellenos, but they are a decent amount of work and we’re just trying to get dinner on the table some nights — amiright?

What is the difference between a Chili, Chilli, and Chile?

I have always thought of “chili” as the 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.

Ingredients for Easy Chile Relleno Recipe

Pretty basic ingredients; remember the quantities and all details are in the recipe card at the end of the post.

  • Whole roasted green chiles | I use canned, but home roasted is great. May also substitute chopped green chiles as well.
  • Monterey Jack Cheese | Slice into sticks! Can also try Pepper Jack cheese, Cheddar, Cotijo, etc.
  • 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, this is my favorite.
  • Milk | I use whole milk in my recipes, but you can substitute whatever you normally use
  • Extra cheese grated for sprinkling on top

How do you make Chile 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! For me, this recipe is tops, because someone else did all of that for me!

But if you are a spice wimp (me-me-me!) then you will want to 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!

Then you simply slice up a hunk o’ cheese, into long “sticks” and tuck them inside the chile peppers. My favorite for these is jack cheese, but you can use cheddar, pepper jack or any deliciously melting cheese, or be authentic and trying the delicious and slightly 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.

The original recipe makes a nice sized 9×9 dish of chili rellenos — it also very easily doubles, making it in a 9×13 dish.

Are Chili 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.

Can I Make Chile Relleno Casserole Ahead of Time?

The short answer is yes! Assemble the chile’s 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.

Can I freeze Baked Chile Rellenos?

I love a good freezer meal, like this Coconut Lime Chicken or Chipotle Chicken so I am all about anything that you can double or triple and then stick one or two in the freezer for one of “those” days.

Make sure it’s completely baked and cooled, wrapped well. I would recommend allowing it to thaw in the refrigerator overnight, then reheating in a 250-300 degree oven (covered with foil) or microwaving.

Gluten Free Chile Relleno Casserole

I have made this dish gluten free many times, and it’s so simple to do, just swap your all purpose flour out for your favorite Gluten Free All Purpose Flour, this is my favorite!

I try as much as possible to provide an easy gluten free variation; my brother and his family are gluten free and I have oodles of friends who are, so I make it a point of always trying to have a GF option!

Fresh Tips

I have been unable to find whole roasted chiles lately, so I modified and used 2-3 (4 oz) cans of diced green chile’s instead and just place them in the dish, with diced chunks of cheese or shredded cheese. Turned out great!

This recipe easily doubles or triples, in fact I can never find 4 oz chiles, and only find 27 oz, I typically double the recipe using all chiles between the two pans.

Make Ahead | You may assemble this dish up to 1 day ahead of time, covering and refrigerating. When ready to bake, remove from fridge and allow to sit on counter for 20-30 minutes before baking as directed above.

Freezer Friendly | Bake as directed allowing to cool completely. Cover with plastic wrap or foil and freeze, freezes well up to a month if covered well. Allow to thaw overnight in fridge, then reheat in 250-300°F oven covered with foil until heated through or may be reheated by the slice in the microwave.
