McDonald’s Hamburger Calories, Price, Nutrition & Allergens
The McDonald’s Hamburger is a timeless classic made with a 100% pure beef patty, expertly seasoned and grilled to perfection. It’s topped with freshly cooked onions, tangy pickles, zesty mustard, and a rich dollop of tomato ketchup, all sandwiched between a soft, warm bun. Simple yet satisfying, every bite delivers the familiar taste and quality McDonald’s Menu is known for.
Please note that onions are now added during cooking, so we cannot guarantee any beef burger will be onion-free, even if removed upon request. The McDonald’s Hamburger remains a reliable, flavorful favorite for any time of the day.
