How to make Chile Relleno Casserole
This is the summary version; see the recipe card below for the complete list of ingredients and the instructions.
First, spray a baking dish with nonstick cooking spray—I used a little olive oil spritz. Then, cut open the green chilies and remove any stems. Lay half of them on the bottom of the casserole dish. Sprinkle with half of the shredded Monterey Jack and cheddar cheese. Then add the rest of the green chilies and top with the remaining Monterey Jack and cheddar cheese.
In a medium bowl, beat the eggs, flour, milk, baking powder, salt, and pepper. Pour the mixture over the chilies and cheese. Bake for 35-40 minutes or until lightly browned on the edges and set in the middle. Top with pico de gallo, salsa, sour cream, green onions, enchilada sauce, or avocado. Let stand for about 10 minutes before slicing.

Preparation Tips
- Canned green chilies can be found in the Hispanic food section of your local grocery store.
- Are you feeding any army? Add 1 pound of cooked ground beef, ground chorizo, or ground pork sausage to the casserole with the two layers of cheese and green chilis.
- Take this recipe to the next level with fresh roasted poblano peppers. Follow this recipe to read more about roasting peppers.
- To increase protein, add shredded chicken between the layers of chiles.

Storage and Reheat
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat the casserole in the oven covered with aluminum foil at 325 degrees for 15-20 minutes or until heated through or in the microwave at 60% power for 2-3 minutes or until warm.
To freeze cover with several layers of plastic wrap followed by a layer of aluminum foil. Freeze for up to 2 months. Thaw in the fridge overnight. Reheat the casserole in the oven covered with aluminum foil at 325 degrees for 15-20 minutes or until heated through or in the microwave at 60% power for 2-3 minutes or until warm.

It says 37 oz. Of the chilies ? Is that 3 seven oz. Cans ?

Linda
Great recipe for Chilies and a nice change
Joy Reynolds
Is there a way to use less eggs? My hubby is sensitive to eggs
Beth Pierce
I have not tried it with less eggs. Is he able to eat just the whites of the eggs?

Would it be possible to do this without flour so it’s gluten free? Is the flour used as a thickener? Wondering if cornstarch would work…
Beth Pierce
Yes, the flour is a thickener. I have never tried it with cornstarch. 1/4 cup seems like a lot of cornstarch. If you try it, I would go with 1-2 tablespoons. Please let us know how it works out.
