Ranch dressing: Balances out the heat with a cool, herby touch and delivers extra savory flavor.
Shredded cheddar cheese: Melts beautifully and gives that classic bubbly, golden finish.
Shredded mozzarella cheese: Lends a gooey, stretchy cheese pull and mild flavor that plays well against the cheddar.

Chopped green onions: Freshness and a slight bite, perfect for finishing the dish with bright color and flavor.
Garlic powder: Gives subtle depth and an aromatic boost to the casserole base.
Onion powder: Rounds out the flavor profile, mingling perfectly with the ranch and cheeses.

Cooking spray or oil for greasing: Ensures easy, mess-free serving and prevents any tragic sticking in your baking dish.

How to Make Jalapeño Buffalo Chicken Casserole

Step 1: Preheat and Prepare the Casserole Dish

Begin by preheating your oven to 375°F and giving your 9×9-inch baking dish a quick coating with oil or cooking spray. This bit takes only a moment but guarantees you’ll be able to scoop every cheesy morsel onto your plate without any sticking or mess.

Step 2: Combine the Main Ingredients

In a large bowl, add the shredded chicken, cooked rice, buffalo wing sauce, softened cream cheese, ranch dressing, garlic powder, onion powder, and a sprinkle of salt and pepper. Use a sturdy spoon (or even your hands) to mix everything until the chicken is coated and the cream cheese is thoroughly incorporated—no streaks, just a uniform, creamy mixture.

Step 3: Add Cheese and Jalapeños

Stir in half of both the cheddar and mozzarella cheeses, along with the chopped pickled jalapeños. This is where the Jalapeño Buffalo Chicken Casserole really comes alive—gooey, cheesy goodness with a pop of zing from the jalapeños ensure every bite is bursting with flavor.

Step 4: Assemble and Top with Cheese

Scoop the mixture into your prepared baking dish and spread it out evenly. Take the remaining cheddar and mozzarella cheeses and sprinkle them generously over the top, ensuring complete, glorious coverage for a perfectly golden crust.

Step 5: Bake Until Bubbly and Perfect

Slide the dish into your preheated oven and bake for 20 to 25 minutes. You’re looking for bubbling edges, melted cheese on top, and that irresistible aroma filling your kitchen. Once out, let it rest for about 5 minutes before adding the vibrant green onions as a garnish.
