What Is Jalapeño Buffalo Chicken Casserole?

Ingredients You’ll Need
To make Jalapeño Buffalo Chicken Casserole, gather the following:
- Chicken: Cooked and shredded or diced (rotisserie chicken works great for convenience).
- Buffalo sauce: Classic wing sauce for that signature spicy tang.
- Jalapeños: Fresh sliced jalapeños add heat and crunch; you can also use pickled for extra tang.
- Creamy base: Ranch dressing or blue cheese dressing to mellow the heat and add richness.
- Cheese: Cheddar, mozzarella, or a mix for gooey, melty goodness.
- Cream cheese or sour cream: Adds creaminess and depth to the sauce.
- Optional extras: Chopped celery for crunch, green onions for freshness, or breadcrumbs for a crispy topping.
Step-by-Step Recipe Instructions
Step 1: Prepare the Chicken
If you don’t have cooked chicken ready, poach or bake chicken breasts or thighs until fully cooked, then shred them with two forks.
Step 2: Mix the Sauce
In a large bowl, combine buffalo sauce, ranch dressing, cream cheese (softened), and sour cream. Stir until smooth and creamy.
Step 3: Combine Chicken and Sauce
Add shredded chicken and sliced jalapeños to the sauce mixture. Toss until the chicken is fully coated.
Step 4: Add Cheese
Fold in shredded cheese, reserving a little to sprinkle on top later.
Step 5: Assemble the Casserole
Transfer the mixture to a greased baking dish. Sprinkle the remaining cheese on top. If you want, add breadcrumbs or crushed tortilla chips for a crunchy topping.
Step 6: Bake
Bake in a preheated oven at 350°F (175°C) for 20-25 minutes or until bubbly and golden on top.
Step 7: Garnish and Serve
Let it cool slightly, then garnish with chopped green onions or cilantro. Serve hot with sides like celery sticks, carrot sticks, or a crisp salad.
