Enjoy the cheesy deliciousness of a McDonald’s Cheeseburger! Our simple, classic cheeseburger begins with a 100% pure beef burger patty seasoned with just a pinch of salt and pepper. The McDonald’s Cheeseburger is topped with a tangy pickle, chopped onions, ketchup, mustard, and a slice of melty American cheese. It contains no artificial flavors, preservatives or added colors from artificial sources.* Our pickle contains an artificial preservative, so skip it if you like.
