Creating these Pesto Chicken Pull Apart Sliders is a simple yet rewarding process. Follow these steps closely to ensure an incredible outcome.

1. Preheat Oven: Set your oven to 350°F (175°C) to preheat.
2. Prepare Baking Dish: Lightly grease a 9×13 inch baking dish to prevent sticking.
3. Mix Chicken and Pesto: In a large bowl, combine the shredded chicken with the pesto sauce. Stir until the chicken is fully coated.
4. Assemble Sliders: Slice the slider buns in half without separating them. Place the bottom halves in the prepared baking dish.
5. Add Chicken Mixture: Layer the chicken and pesto mixture evenly over the bottom halves of the buns.
6. Add Cheese: Sprinkle shredded mozzarella cheese and grated Parmesan cheese generously on top of the chicken.
7. Top with Buns: Place the top halves of the slider buns over the cheese layer.
8. Prepare Butter Mixture: In a small bowl, mix the melted butter with garlic powder and Italian seasoning. Brush this mixture generously over the tops of the slider buns.
9. Bake: Cover the baking dish with aluminum foil and bake for 20 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the tops are golden brown.
10. Cool and Slice: Once baked, remove the sliders from the oven and allow them to cool for a few minutes. Slice between the buns to create pull-apart portions.
11. Garnish: Optionally, garnish with fresh basil leaves for a burst of color and flavor before serving.
