Ingredients
  

  • Cooked chicken (shredded or diced, about 4 cups; rotisserie works great)
  • Buffalo hot sauce (such as Frank’s RedHot; 3/4 to 1 cup, to taste)
  • Ranch dressing or blue cheese dressing (1/2 cup)
  • Cream cheese (8 oz, softened)
  • Sour cream or plain Greek yogurt (1/2 cup)
  • Shredded cheese (2 to 3 cups total; a mix of mozzarella and sharp cheddar works well)
  • Cooked base (choose one: 4 cups cooked rice, 1 lb cooked short pasta, or 1.5 lbs cooked diced potatoes or frozen hash browns)
  • Celery (2 ribs, finely chopped)
  • Green onions (3 to 4, sliced)
  • Garlic (2 cloves, minced) or 1/2 teaspoon garlic powder
  • Onion powder (1/2 teaspoon)
  • Salt and black pepper (to taste)
  • Unsalted butter (2 tablespoons, optional, for extra richness)
  • Blue cheese crumbles (optional, for topping)
  • Nonstick spray or a little oil (for the baking dish)

Method
 

  1. Heat the oven: Preheat to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
  2. Prep the chicken and base: Shred or dice cooked chicken. Cook your base—rice, pasta, or diced potatoes—until just tender. Drain pasta well; if using hash browns, thaw and pat dry.
  3. Make the buffalo cream sauce: In a large bowl, whisk cream cheese, sour cream, ranch or blue cheese dressing, and buffalo hot sauce until smooth. If your cream cheese is cold, microwave it for 15–20 seconds to soften. Stir in garlic, onion powder, salt, and pepper. Taste and adjust heat with more hot sauce if desired.
  4. Add butter (optional): Melt 2 tablespoons butter and whisk it into the sauce for extra silkiness and a classic buffalo flavor.
  5. Combine the mix-ins: Stir in the chicken, chopped celery, half the green onions, and about 1 cup shredded cheese. Fold in your cooked base until evenly coated.
  6. Assemble the casserole: Spread the mixture into the prepared baking dish. Top with the remaining shredded cheese in an even layer.
  7. Bake: Bake uncovered for 20–25 minutes, until the casserole is hot and the cheese is melted and bubbly around the edges.
  8. Finish and garnish: Let it rest 5–10 minutes so it sets slightly. Drizzle with a little extra buffalo sauce and ranch or blue cheese dressing. Sprinkle remaining green onions and blue cheese crumbles on top.
  9. Serve: Scoop generous portions and serve with celery sticks, a crisp salad, or garlic bread.
