Use fresh, high-quality turkey breast for best flavor. Don’t skip the butter topping for a golden crisp finish. Customize the sauce by adding smoked paprika or hot sauce. Make ahead by assembling and refrigerating until ready to bake. Variations include swapping cheeses, making a vegetarian version, adding spicy elements, or using different bread types. Store leftovers in an airtight container for up to 3 days and reheat in the oven for best results. Sliders can be frozen unbaked for up to 1 month.
