Some people say The Original Slider® is perfect and can’t be topped. To those people, we say “how about a slice of tasty, melty American Cheese?” The classic combo of 100% beef and grilled onions on our signature bun was already craveable. We just made it more satisfying and irreplaceable. Want to create that same Castle experience in your home, try ‘em with a couple slices of dill pickles.
