Ingredients You’ll Need

To make this casserole, you’ll need a handful of simple ingredients. Here’s what to gather:

Chicken: Boneless, skinless chicken breasts or thighs, cooked and shredded or diced
Jalapeños: Fresh or jarred jalapeños work well—adjust the quantity to suit your spice preference
Cream Cheese: The rich and creamy foundation of the sauce
Shredded Cheese: Cheddar, Monterey Jack, or a blend
Sour Cream: Adds tanginess and helps create a smooth, creamy base
Bacon: Cooked and crumbled for smoky, savory flavor
Garlic Powder, Onion Powder, Paprika: Basic seasonings for extra depth
Optional Toppings: Breadcrumbs or crushed pork rinds for added crunch

Step-by-Step Instructions

Making jalapeño popper chicken casserole is straightforward and stress-free. Here’s how to bring it all together:

Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
Cook the chicken (if not already cooked). Season it lightly with salt, pepper, and garlic powder, then shred or dice it.
Prepare the sauce: In a large bowl, combine softened cream cheese, sour cream, shredded cheese, chopped jalapeños, and seasonings. Mix until smooth.
Assemble the casserole: Spread the chicken evenly in the baking dish, then pour the cheese mixture over the top. Use a spatula to smooth it out.
Add toppings: Sprinkle with cooked bacon and optional breadcrumbs or pork rinds.
Bake for 20–25 minutes, or until hot and bubbly. If the top isn’t golden enough, broil for 2–3 minutes at the end.
Let cool slightly before serving.

Tips for the Best Casserole

Balance the heat: Remove seeds and membranes from the jalapeños for less spice, or leave them in for more heat.
Make ahead: Assemble the casserole in advance and refrigerate until ready to bake.
Substitutions: Use Greek yogurt instead of sour cream, or try dairy-free cheese for a lactose-free version.
Avoid a watery casserole: Use cooked, well-drained chicken and avoid overloading the dish with wet ingredients.

Variations and Add-Ins

This casserole is easy to customize. Here are a few ideas:

Keto-friendly: Swap breadcrumbs for crushed pork rinds.
Add carbs: Mix in cooked pasta, rice, or quinoa for a heartier meal.
Add veggies: Stir in cooked spinach, corn, or bell peppers for extra nutrition.
Swap the protein: Use ground chicken, turkey, or rotisserie chicken for a shortcut.
