Baked Chile Relleno Casserole Recipe

Chile relleno casserole recipe - Dr. Axe

I’m a huge fan of Tex-Mex foods. But usually, heavy carbs make up the base of these recipes. Fajitas, enchiladas and tacos all rely on tortillas. That’s why this chile relleno casserole recipe is so special. Not only is it packed with the seasonings and ingredients you love ­— yes, including cheese! — but it’s keto-friendly and delicious.

What Is Chile Relleno?

Chile relleno, or “stuffed chile,” is a Mexican recipe originating from the city of Puebla; This is where poblano peppers, the type of peppers we’ll use in this recipe, get their name. (1) Traditionally, the poblano peppers are roasted and then filled with a cheese and meat filling. Next, they’re dipped in an egg batter and deep fried, then smothered in sauce.

They’re enjoyed throughout the year, which is no surprise considering how tasty they are. In this recipe, I’ve kept the best parts of the classic recipe and given it little twist by turning this dish into a chile relleno casserole!

We’ll broil the spicy poblano peppers to get that charred look and flavor you’d get if roasting over a grill, but instead of stuffing the peppers, which can get messy, we’ll chop the peppers up, tossing them with some other epic ingredients, like beef bacon, cheese, cauliflower rice, mushrooms, tomato sauce and avocado.

If you’re following a keto diet, this version of chile relleno is definitely a keto-friendly recipe you want up your sleeve. With two types of cheeses and avocado, this chile relleno casserole is packed with healthy fats to help keep you in ketosis. To adhere to a high-fat, low-carb lifestyle, we’ll skip the white rice that’s common in Mexican cooking and replace it with cauliflower rice to keep the texture and taste without extra carbs.

How to Make a Chile Relleno Casserole

So how do you make this Mexican-inspired chile relleno casserole?

Chile relleno casserole step 1 - Dr. Axe

Start by turning on your oven to the high broil setting. This is how we’ll “roast” our peppers.

Chile relleno casserole step 2 - Dr. Axe

Slice the stems off the poblano peppers and discard. Then slice each pepper in half to remove the seeds and veins of the peppers. Poblano peppers aren’t super spicy, especially once they’re roasted, but they do have a little kick to them. If your family prefers really mild foods, you can substitute bell peppers for the poblanos, but you’d be missing out!

Chile relleno casserole step 3 - Dr. Axe

Place the peppers on a baking sheet. You want the insides of the peppers facing down here. Broil for 10 minutes, or until the peppers are nice and charred. Don’t turn the oven off just yet, though … Preheat it to 350 degrees Fahrenheit.

    Wow. Seems like A nice recipe but its a crime to call it tex mex or chile relleno.. Dill?? Goat cheese? So not a chili relleno recipe. Mushrooms?? Cauliflower.. killing me..haha

    • Sharon on

      It’s quite the ingenius recipe. The flavor is strongly reminiscent of a Chile relleno actually. The bacon and charred Chile give it a smoky flavor and the goat cheese and Romano just enough cheese to comfort. The cauliflower gives it substance or bite. It screamed “serve me with pintos” which I did for my husband’s leftovers in his lunch. So, admittedly alternative but a close enough imposter to enjoy, knowing it’s healthier.
