Step-by-Step Instructions
Preheat and Prepare Dish
Preheat oven to 375°F (190°C). Lightly coat a 9×13-inch casserole dish with nonstick spray.
Prepare the Chicken
Chop chicken breasts into evenly sized bite-sized cubes. Spread them in a single, even layer in the prepared casserole dish.
Make the Creamy Sauce
In a mixing bowl, combine softened cream cheese, garlic powder, and heavy cream. Use a hand mixer to blend until smooth and creamy.
Layer the Ingredients
Pour the cream cheese mixture evenly over the chicken cubes. Scatter diced jalapeños across the top.
Add Cheese
Sprinkle shredded cheddar evenly over the jalapeño layer, fully covering the surface.
Bake Until Done
Bake for 40–45 minutes, or until the cheese is melted and bubbly and the chicken reaches an internal temperature of 165°F (74°C).
Finish with Bacon
Remove from oven and top with crumbled crispy bacon just before serving.

This casserole works because it mimics the structure of jalapeño poppers—creamy cheese base, spicy peppers, and smoky bacon—while adding protein-rich chicken for substance. Baking allows the cream cheese and heavy cream to form a cohesive sauce that thickens as it cools. The cheddar melts into a rich topping that seals moisture into the chicken. At just 350 calories and 3 grams of carbs per serving, it delivers indulgent comfort while staying keto-friendly.
