Easy to make chili relleno casserole is as delicious as regular chili relleno but in an easy to make casserole.
Perfect served as a main dish for dinner or even for breakfast or brunch!
Why make this recipe
Have you ever had chili relleno? The authentic version is a poblano pepper stuffed with cheese and then dipped into an egg batter and deep fried. They are delicious, but take 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 that 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.
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.
- Peppers - I used fresh roasted poblano peppers. You can use any mild pepper or use canned roasted chili 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.
- Milk - Whole milk or whatever you have on hand
Steps to make
