By the early 2010s, amid the pop-up restaurant phenomenon, food trucks offering gourmet cuisine and a variety of specialties and ethnic menus became particularly popular.Food trucks may also sell cold beverages such as soda pop and water. Food trucks, along with food booths and food carts, are major components of the street food industry that serves an estimated 2.5 billion people every day.

In the United States, the Texas chuckwagon is a precursor to the American food truck. In the later 1800s, herding cattle from the Southwest to markets in the North and East kept cowhands on the trail for months at a time. In 1866, the "father of the Texas Panhandle", Charles Goodnight, a Texas cattle rancher, fitted a sturdy old United States Army wagon with interior shelving and drawers, and stocked it with kitchenware, food and medical supplies.

Food consisted of dried beans, coffee, cornmeal, greasy cloth-wrapped bacon, salt pork, beef, usually dried or salted, and other easy to preserve food stuffs. The wagon was also stocked with a water barrel and a sling to kindle wood to heat and cook food.

Another early relative of the modern food truck is the lunch wagon, as conceived by food vendor Walter Scott in 1872. Scott cut windows in a small covered wagon, parked it in front of a newspaper office in Providence, Rhode Island, and sold sandwiches, pies and coffee to pressmen and journalists.

By the 1880s, former lunch-counter boy, Thomas H. Buckley, was manufacturing lunch wagons in Worcester, Massachusetts. He introduced various models, like the Owl and the White House Cafe, with features that included sinks, refrigerators and cooking stoves, also colored windows and other ornamentation.

Later versions of the food truck were mobile canteens, which were created in the late 1950s. These mobile canteens were authorized by the U.S. Army and operated on stateside army bases.

Mobile food trucks, nicknamed "roach coaches" or "gut trucks", have been around for years, serving construction sites, factories, and other blue-collar locations. In big cities of the U.S. the food truck traditionally provided a means for the on-the-go person to grab a quick bite at a low cost. Food trucks are not only sought out for their affordability but as well for their nostalgia; and their popularity continues to rise.

During the 2010s the economic changes caused by the Great Recession, technological factors, and street food being "hip" or "chic" have combined to increase the number of food trucks in the United States. The construction business was drying up, leading to a surplus of food trucks, and chefs from high-end restaurants were being laid off. For experienced cooks suddenly without work, the food truck seemed a clear choice, and a smaller financial investment than a brick-and-mortar restaurant.

Once more commonplace in American coastal big cities like New York City and Los Angeles, gourmet food trucks are now to be found as well in the suburbs, and in small towns across the country. Food trucks are also being hired for special events, like weddings, movie shoots, and corporate gatherings, and also to carry advertising promoting companies and brands.

In 2011, USA Today noted that food trucks selling pricier food were gaining popularity across the United States, contrary to a common perception that food trucks are typically run-down and found at construction sites. In 2009, New York magazine noted that the food truck had "largely transcended its roach-coach classification and is now a respectable venue for aspiring chefs to launch careers."

These gourmet trucks' menus run the gamut of ethnic and fusion cuisine. Often focusing on limited but creative dishes at reasonable prices, they offer customers a chance to experience food they otherwise may not. Finding a niche seems to be a path to success for most trucks. While one truck may specialize in outlandish burgers, another may serve only lobster rolls.

Gourmet food trucks can also offer a unique dining experience. With the rise of millennial diners, experiential dining has become more mainstream, driving restaurant and food truck owners to create a unique experience for their customers. As food trucks are mobile, this provides an advantage to gourmet trucks to take their experience anywhere they may please.

Tracking food trucks has been made easy with social media like Facebook and Twitter, where a favorite gourmet truck can be located at any moment, with updates on specials, new menu items and location changes.

Food truck rallies and food truck parks are also growing in popularity in the US. At rallies, people can find their favorite trucks all in one place and as well provide a means for a variety of diverse cultures to come together and find a common ground over a love for food.

 On August 31, 2013, Tampa hosted the world's largest food truck rally, with 99 trucks attending. The Tampa Rally broke its own record by bringing together 121 food trucks in 2014. Chicago Food Truck Festival hosts over 40 trucks each year with 60,000 guests participating over two days in Chicago. And food truck parks, offering permanent locations, are found in urban and suburban areas across the US.

The popularity of food trucks lead to the creation of associations that protect and support their business rights, such as the Philadelphia Mobile Food Association.

Food trucks are subject to the same range of concerns as other foodservice businesses. They generally require a fixed address to accept delivery of supplies. A commercial kitchen may be needed for food prep. There are a variety of permits to obtain, and a health code to observe. Labor and fuel costs are a significant part of the overhead.

Legal definitions and requirements for food trucks vary widely by country and locality. For example, in Toronto, some of the requirements include business and liability insurance, a Commercial Vehicle Operator's Registration for the truck, permits for each municipality being operated in (downtown, various suburbs), a food handler certificate, appropriate driver's licenses for drivers, assistant's licenses for assistants, and a health inspection.

As the rising number and popularity of food trucks push them into the food mainstream, region by region, problems with local legislators and police reacting to new situations, and pushback from brick-and-mortar restaurants fearing competition, are amongst issues having to be worked through, creating significant business uncertainty.

Chicago long held the distinction of being the only city in the United States that did not allow food trucks to cook on board, which required trucks to prepare food in a commercial kitchen, then wrap and label the food and load it into a food warmer. In 2012, under pressure from food truck owners and supporters, including the University of Chicago Law School, regulations were changed to allow on-board cooking, however, controversially, food trucks are required to park 200 feet away from any restaurant, which virtually eliminates busy downtown locations (an example of pushback, restaurant owners lobbying city government).

In the US, specialized food truck outfitters offer comprehensive start-up services that can include concept development, training, and business support, in addition to outfitted trucks.[40] Often, however, it makes more sense for a new operator to lease a truck.[41] In the US, food trucks are a $1.2 billion industry. By 2017, the US food truck industry had surpassed $2.7 billion.

Expansion from a single truck to fleets and retail outlets has proven possible. Los Angeles-based gourmet ice cream maker Coolhaus grew from a single truck in 2009 to 11 trucks and carts, two storefronts, and over 2,500 retail partner stores by September 2014.

The libertarian Reason magazine states that in US, cities, food trucks are subject to protectionist regulations designed to prevent them from competing with brick and mortar restaurants. For example, in Chicago, a regulation prevents food trucks "...from selling food within 200 feet of brick-and-mortar restaurants and, hence, prohibit them from operating throughout the city's downtown area", which critics have called an "anti-competitive" rule for food truck operators.
