This keto jalapeno popper chicken casserole is a delightful blend of creamy, cheesy, and spicy flavors. It's perfect for those following a low-carb diet but still craving something hearty and satisfying. The combination of shredded chicken, cream cheese, and jalapenos creates a dish that's both comforting and exciting.
If you don't usually keep jalapenos or cream cheese at home, you might need to make a special trip to the supermarket. Jalapenos add a spicy kick to the dish, while cream cheese provides a rich, creamy texture. Make sure to check the spice level of the jalapenos to suit your taste.

Ingredients for Keto Jalapeno Popper Chicken Casserole
Chicken: Provides the protein base for the casserole.
Cream cheese: Adds a rich, creamy texture to the dish.
Cheddar cheese: Offers a sharp, cheesy flavor that complements the cream cheese.
Jalapenos: Brings a spicy kick to the casserole.
Garlic powder: Enhances the overall flavor with a hint of garlic.
Onion powder: Adds a subtle onion flavor without the texture of actual onions.
Paprika: Provides a smoky, slightly sweet flavor.
Salt: Enhances all the other flavors in the dish.

Technique Tip for This Recipe
When combining the shredded chicken with the cream cheese, make sure the cream cheese is fully softened to ensure a smooth and even mixture. This will help the cheddar cheese and jalapenos distribute more uniformly throughout the casserole, giving you a consistent flavor in every bite. Additionally, consider using freshly shredded cheddar cheese instead of pre-shredded to avoid any added starches that can affect the texture.

How to Store or Freeze This Casserole
Allow the casserole to cool completely before storing. This helps prevent condensation, which can make the dish soggy.
For short-term storage, transfer the casserole to an airtight container. Refrigerate for up to 3-4 days.
If you plan to freeze the casserole, portion it out into individual servings. This makes reheating easier and reduces waste.
Wrap each portion tightly with plastic wrap or aluminum foil. Then, place the wrapped portions in a freezer-safe bag or container. Label with the date for easy tracking.
To reheat from the refrigerator, preheat your oven to 350°F (175°C). Place the casserole in an oven-safe dish and cover with foil. Heat for about 20 minutes or until warmed through.
For reheating from frozen, it’s best to thaw the casserole in the refrigerator overnight. Once thawed, follow the same reheating instructions as above.
If you need to reheat directly from frozen, preheat your oven to 350°F (175°C). Place the casserole in an oven-safe dish, cover with foil, and bake for 45-60 minutes, or until heated through. Remove the foil for the last 10 minutes to allow the top to crisp up.
Avoid using the microwave for reheating, as it can make the cream cheese and cheddar cheese separate and become oily.
For a quick reheat, you can use a stovetop method. Place the casserole in a non-stick skillet over medium heat. Stir occasionally until heated through, adding a splash of chicken broth if needed to keep it moist.
