Question: how many calories are in a mcdonald's burger?
Answer: 300 Cal. Our simple, classic cheeseburger begins with a 100% pure beef patty seasoned with just a pinch of salt and pepper. It's 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.
