Step-by-step overview

Making Keto Jalapeno Popper Chicken Casserole is straightforward. You’ll start by creating a creamy base using cream cheese, sour cream, and seasonings.

This mixture is spread into a greased baking dish, topped with cheddar cheese, and garnished with the remaining jalapeños and turkey bacon. A quick bake later, and you’re ready to serve!

Gather these items

To create this delicious dish, here’s what you’ll need:

  • 2 lbs cooked chicken breast, shredded
  • 8 oz cream cheese, softened
  • 1/2 cup sour cream
  • 1/4 cup heavy cream
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon ground black pepper
  • 5 large jalapenos, seeded and diced
  • 2 cups shredded sharp cheddar cheese
  • 8 slices turkey bacon, cooked and crumbled

Feel free to adjust some ingredients based on your dietary preferences. For instance, Greek yogurt can be used in place of sour cream for a lighter option.

Directions to follow

  1. Preheat your oven to 375°F (190°C) and grease a 9×13 inch baking dish with non-stick spray.
  2. In a large mixing bowl, whisk together the softened cream cheese, sour cream, heavy cream, garlic powder, onion powder, salt, and pepper until you have a smooth emulsion.
  3. Gently fold in the shredded chicken and half of the diced jalapeños until everything is evenly combined.
  4. Transfer this creamy chicken mixture to the prepared baking dish, smoothing it out with a spatula.
  5. Generously sprinkle the shredded cheddar cheese over the top, creating a delicious cheesy layer.
  6. Garnish with the remaining diced jalapeños and crumbled turkey bacon for added flavor.
  7. Bake the casserole for 20 to 25 minutes or until the cheese is completely melted, bubbly, and tinged with golden brown edges, and the center reaches 165°F (74°C).
  8. Once done, remove it from the oven and let it rest for 5 minutes to set before serving.

When you’re ready to eat, thaw in the refrigerator and reheat until it reaches 165°F.

Creative twists

Feel free to get creative with this recipe! If you’re looking for a different flavor profile, try substituting the sharp cheddar with pepper jack cheese for a spicier kick, or stir in a spoonful of chopped pickled jalapeños for extra tang.

FAQs

Can I use rotisserie chicken instead of cooked chicken?

Absolutely! Rotisserie chicken works great for saving time and adds a delicious flavor.

What if I want to make this dairy-free?

You can substitute dairy products with dairy-free alternatives, such as using cashew cream in place of cream cheese and coconut cream instead of sour cream.

How long does this casserole take to prepare?

The prep time is about 15-20 minutes, and another 20-25 minutes in the oven, so you can have it on the table in about 45 minutes.
