Ingredients

Scale

Chicken

  • 3 to 4 boneless, skinless chicken breasts, cubed

Seasoning and Sauce

  • ½ tbsp garlic powder
  • 8 oz cream cheese, softened
  • ½ cup heavy cream
  • 5 to 6 jalapeno peppers, seeded and diced

Topping

  • 2 cups shredded sharp cheddar cheese

Instructions

  1. Preheat the oven: Set your oven to 375°F (190°C) and prepare a 9×13 inch casserole dish by spraying it thoroughly with nonstick cooking spray to prevent sticking.
  2. Layer the chicken: Arrange the cubed boneless, skinless chicken breasts evenly on the bottom of the casserole dish, leaving a little space between pieces for even cooking.
  3. Prepare the creamy sauce: In a bowl, blend together garlic powder, softened cream cheese, and heavy cream until smooth and well combined. Pour this mixture evenly over the chicken pieces.
  4. Add jalapenos and cheese: Sprinkle the diced, seeded jalapeno peppers evenly over the creamy sauce layer, then top everything with the shredded sharp cheddar cheese.
  5. Bake the casserole: Place the casserole dish in the oven and bake for 40 to 45 minutes or until the chicken is fully cooked through and the cheese on top is melted and lightly golden.

Notes

  • Remove seeds from jalapenos to control the heat level; leaving some seeds will make it spicier.
  • Use full-fat cream cheese and heavy cream for best keto-friendly results and creaminess.
  • Chicken is fully cooked when it reaches an internal temperature of 165°F (74°C).
  • Let the casserole rest for 5 minutes after baking to allow flavors to meld.
  • You can add cooked bacon bits on top before baking for extra flavor.
