Step‑by‑Step Instructions for Keto Jalapeno Popper Casserole
Step 1: Preheat the Oven
Start by preheating your oven to 375°F (190°C) while you prepare your casserole dish. Lightly coat a 9×13 casserole dish with nonstick cooking spray to ensure easy cleanup and perfect browning. This step is essential to get the casserole bubbling beautifully as it bakes.
Step 2: Prepare the Chicken Layer
Evenly layer the cubed chicken breasts on the bottom of the prepared casserole dish, spacing the pieces slightly apart for even cooking. Make sure the chicken is cubed uniformly to allow for thorough baking. You’ll want the base to be neatly arranged, as it will be the heart of your Keto Jalapeño Popper Casserole.
Step 3: Mix the Creamy Base
In a mixing bowl, combine the garlic powder, softened cream cheese, and heavy cream. Blend these ingredients until you achieve a smooth and creamy mixture, using a hand mixer or spatula. This creamy base is crucial for binding the dish together and creating that luscious texture you’ll savor in every bite.
Step 4: Add the Jalapeños
Pour the creamy mixture over the layered chicken, making sure to distribute it evenly for thorough coverage. Next, sprinkle the diced jalapeños generously over the top. The warm, spicy notes from the jalapeños will infuse the dish, bringing that signature flavor of jalapeño poppers right into your casserole.
Step 5: Top with Cheese
Finish by sprinkling the shredded cheddar cheese generously over the jalapeños, ensuring an even coating. This will create a golden, bubbly crust as the casserole bakes. The cheese not only enhances the flavor but also adds a savory richness that’s hard to resist in your Keto Jalapeño Popper Casserole.
Step 6: Bake the Casserole
Place the casserole in the preheated oven and bake for 40-45 minutes. You’ll know it’s done when the chicken is fully cooked, reaching an internal temperature of 165°F, and the cheese is melted and golden brown. The enticing aroma will fill your kitchen, letting everyone know that a delicious meal is on its way.
Step 7: Garnish and Serve
Once baked, remove the casserole from the oven and let it rest for about 5 minutes. This allows the layers to set for easier serving. Just before serving, garnish with the crumbled bacon for that delicious crunch. Your Keto Jalapeño Popper Casserole is now ready to delight your family!

Keto Jalapeño Popper Casserole Recipe FAQs
How do I select the right jalapeños for my casserole?
When choosing jalapeños, look for firm peppers that are vibrant in color without any dark spots or wrinkles. The more vibrant they are, the fresher and more flavorful they will be! Adjust the quantity based on how much heat you desire; I often recommend starting with 5 for a nice kick that isn’t overwhelming.

To store your casserole, place it in an airtight container in the refrigerator for up to 3 days. When you’re ready to enjoy it again, you can reheat it in the oven at 350°F (175°C) for 20-30 minutes or microwave it until heated through. This ensures it retains its delicious creamy texture!

What’s the best way to reheat the casserole?
For the best results when reheating, place the casserole in an oven preheated to 350°F (175°C). Cover it with aluminum foil to prevent the top from browning too much, and heat for approximately 20-30 minutes or until warmed through. This method helps keep the casserole creamy and delicious!

Of course! To increase the heat, leave some seeds in the jalapeños, or try using spicier varieties like serrano peppers.
