Overview

A burger is a sandwich built around one or more cooked patties, most commonly ground beef, served inside a split bun or roll. Over time the term "burger" has expanded to include patties made from pork, poultry, fish, legumes, vegetables and modern plant-based protein substitutes. Burgers range from simple fast-food items to elaborate gourmet constructions served in restaurants.

Components and common ingredients

The core elements are the patty and the bread. Typical toppings include cheese, lettuce, tomato, onion and pickles, with condiments such as ketchup, mustard and mayonnaise. Variations add ingredients like bacon, sautéed mushrooms, avocado, fried egg or specialty sauces. Patty texture and flavor depend on the meat-to-fat ratio, seasoning and how the patty is formed and cooked.

History and development

The burger evolved from minced-beef dishes such as the Hamburg steak in 19th-century Europe and became popular as a portable sandwich in the United States around the turn of the 20th century. Street vendors, diners and later fast-food chains contributed to its widespread availability and many of the conventions associated with the modern hamburger.

Variations and examples

  • Cheeseburger — with melted cheese on the patty.
  • Slider — small burgers served in multiples.
  • Patty melt — served on toasted bread with cheese and onions.
  • Veggie and plant-based — made from legumes, grains, fungi or protein isolates.
  • Regional styles — differing in seasoning, bun type and garnishes across countries and cities.

Preparation, safety and nutrition

Burgers are cooked by grilling, pan-frying, broiling or deep-frying; techniques such as pressing ("smash" burgers) influence crust formation and juiciness. Food-safety guidance commonly advises cooking ground meat to a temperature sufficient to reduce pathogens. Nutritional profiles vary widely: a burger can be a source of protein and nutrients but also of saturated fat and calories depending on ingredients and portion size.

Cultural role and global impact

Burgers function as both everyday convenience food and a canvas for culinary innovation. They are central to fast-food culture yet also appear in high-end gastronomy. Adaptations reflect local tastes and ingredients, making the burger a broadly recognisable and adaptable element of contemporary cuisine worldwide.
