Step‑by‑Step Instructions for Keto Jalapeno Popper Chicken Casserole
Step 1: Preheat the Oven
Start by preheating your oven to 375°F (190°C). While the oven is heating up, take a moment to grease a 9×13 inch baking dish with cooking spray or a dab of butter. This will ensure your Keto Jalapeno Popper Chicken Casserole comes out effortlessly once baked.
Step 2: Mix Ingredients
In a large mixing bowl, whisk together 8 oz of softened cream cheese, 1/2 cup of sour cream, and 1/4 cup of heavy cream until the mixture is creamy and smooth. Sprinkle in 1 tsp each of garlic powder and onion powder, along with 1/2 tsp of kosher salt and 1/4 tsp of ground black pepper, blending thoroughly to create a flavorful base for your casserole.
Step 3: Combine Chicken
Next, gently fold in 2 lbs of shredded cooked chicken breast and half of your diced jalapenos (about 2-3 jalapenos). Ensure everything is evenly mixed, so every bite of your Keto Jalapeno Popper Chicken Casserole is packed with delicious flavor.
Step 4: Transfer Mixture
Take the well-combined chicken mixture and spread it evenly into the greased baking dish you prepared earlier. Use a spatula to smooth it out, making sure it’s evenly distributed so that every portion bakes beautifully in the oven.
Step 5: Add Cheese & Toppings
Now it’s time to make your casserole even more delightful! Sprinkle 2 cups of shredded sharp cheddar cheese generously over the top. For added excitement, garnish with the remaining diced jalapenos and the crumbled bacon from 8 slices. This layering will result in a deliciously crispy topping once baked.
Step 6: Bake
Place your assembled casserole in the preheated oven and bake for 20-25 minutes. You’ll know it’s ready when the cheese is melted, bubbling, and golden brown at the edges, creating an irresistible appeal that will draw everyone to the kitchen.
Step 7: Rest Before Serving
Once baked to perfection, take the casserole out of the oven and let it sit for about 5 minutes before serving. This brief resting time will help the flavors meld and allow the dish to firm up slightly, making it easier to serve and enjoy your comforting Keto Jalapeno Popper Chicken Casserole!
