These Barbecue Chicken Sliders are a deliciously easy dinner the whole family will love. Ideal for make-ahead and feeding a crowd.
I love serving slider casseroles like this Cheeseburger casserole, my classic Ham and Swiss sliders, Horseradish Roast Beef sliders, or this Reuben Slider Casserole.
This barbecue chicken slider casserole features shredded chicken tossed in tangy barbecue sauce and piled on top of cheddar cheese.
But it's the toppings that make this sandwich awesome. Pickled onions cut through the richness of the BBQ sauce and crispy french-fried onions add crunch. A drizzle of ranch dressing provides the creamy sauce vibe that every sandwich needs.
