What Is Jalapeño Popper Chicken Casserole?

Jalapeño Popper Chicken Casserole is a delightful twist on the traditional jalapeño popper appetizer, transformed into a satisfying weeknight meal. In this casserole, you’ll find all the classic ingredients of a jalapeño popper, such as jalapeño peppers, cheese filling, and bacon, but with added chicken.

The jalapeño peppers are sliced and combined with a cheesy filling, typically made with cream cheese and shredded cheddar or Monterey Jack cheese to make the casserole. The chicken is usually cooked and shredded beforehand, and crispy bacon pieces are added.

Once all the ingredients are combined, the mixture is spread into a baking dish and baked until the cheese is melted and bubbly and the flavors have melded together. The result is a flavorful, slightly spicy, and creamy casserole that incorporates the essence of jalapeño poppers.

This casserole can be enjoyed as a main course, accompanied by side dishes like salads, vegetables, or low-carb options for a keto-friendly meal. It’s a popular choice for those seeking a comforting and satisfying dish with a kick of flavor from the jalapeños.

Keto Jalapeno Popper Casserole Without Chicken

I made a keto jalapeño popper casserole without chicken the other day, and it was a hit!

I started by preheating the oven to 375°F and greasing a baking dish.

For the base, I mixed together 8 oz of softened cream cheese, 1 cup of shredded cheddar, 1 cup of shredded mozzarella, and 1/2 cup of heavy cream, with salt and pepper. I then folded in 3 diced jalapeños (seeds removed for less heat) and 1/2 cup of crispy crumbled bacon. I spread this mixture into the prepared baking dish.

For the topping, I combined another 1/2 cup each of shredded cheddar and mozzarella and sprinkled it evenly over the base. I baked it for about 20 minutes, or until bubbly and golden on top.

Before serving, I garnished it with additional crumbled bacon and some chopped fresh parsley. It was the perfect spicy and creamy keto treat!
