Making this gluten-free jalapeño popper casserole really is quick and simple. You’ll start off by cooking and crumbling your bacon and setting it aside.

Next, season your chicken tenderloins (or boneless thighs for extra flavor!) with chipotle powder, salt, and black pepper.

Then, you’ll prepare the creamy sauce by combining the softened cream cheese and sour cream and adding onion and garlic powder.

Once combined well, all that’s left is to assemble the casserole and bake it. I told you it was easy!

You’ll simply place the chicken at the bottom of your dish, cover it with the cream cheese/sour cream mixture, and top the whole thing with shredded cheddar, cooked bacon, and green onions.

Pop your casserole in the oven for 30–40 minutes until the cheese is bubbly and lightly browned, and enjoy!

However, if you want to round out your meal further, you can certainly serve this with a simple side.

I recommend that you choose a mild side dish since the flavor of jalapeños can quickly overwhelm a dish.

Also, choose keto sides that come together easily.
