Tried & True Baked Chile Relleno Recipe
Have you ever had chile relleno? The authentic version is a poblano pepper stuffed with cheese, dipped into an egg batter, and deep-fried. They are delicious, but takes a bit of work to get them just right.
I have a much easier version with this chile casserole. This recipe comes from my mother-in-law. She got it from a friend years ago.
I think she's probably been making this for more than 40 years. When you've got something this delicious, it becomes a regular recipe made again and again.
The Secret to Chiles Rellenos Casserole
This dish starts with the peppers. The better the peppers, the better the casserole. I used poblano peppers and roasted, peeled, and seeded them. Read this post on roasting chili peppers to find out how I roast my peppers.
Using fresh peppers is the best, but they aren't always available or you might be limited on time. I often freeze roasted peppers in the summertime and the frozen peppers can be thawed and used.
You can also buy canned roasted chilies at the store. Try to get the whole chilies, not diced.
Chile Relleno Casserole Recipe Ingredients
- Peppers - I used fresh roasted poblano peppers. You can use any mild pepper or canned roasted peppers
- Cheese - For this recipe, I used Monterey Jack. Feel free to use part cheddar and part Jack cheese. Pepper Jack cheese would also be delicious and add a little extra spice.

- Eggs

How do you store and reheat the leftovers?
Kathy says
Hi Julie,
Cover any leftovers and store in the refrigerator for up to 4 days. To reheat a single portion place on a microwave safe dish and heat for 60-90 seconds. To reheat a larger portion you can use the oven at 350 for 10-15 minutes. Cover with foil while in the oven.
Enjoy,
Kathy
