The Olive Garden started as a unit of General Mills. The Olive Garden's first restaurant was opened on December 13, 1982, in Orlando, Florida by co-founders Blaine Sweatt, Mark Given, Gino DeSantis and Dave Manuchia. By 1989, there were 145 The Olive Garden restaurants, making it the fastest-growing units in the General Mills restaurant division. The Olive Garden restaurants were uniformly popular, and the chain's per-store sales soon matched former sister company Red Lobster. The company eventually became the largest chain of Italian-themed full-service restaurants in the United States.
General Mills spun off its restaurant holdings as Darden Restaurants (named after Red Lobster founder Bill Darden), a stand-alone company, in 1995. Olive Garden removed "The" from its name in 1998 as part of a rebranding which introduced the slogan "When you're here, you're family". In 2009, Olive Garden was Darden's most inexpensive restaurant chain with an average check per person of $15.00 (USD) versus over $90 at its sibling Capital Grille.
Newer restaurants are styled after a farmhouse in the town of Castellina in Chianti, Tuscany, on the grounds of the Rocca delle Macie winery. The farmhouse is home to the Riserva di Fizzano restaurant adjoining the company's Culinary Institute of Tuscany which was founded in 1999.
In 2010, Olive Garden generated $3.3 billion in sales. Its closest competitor, Carrabba's Italian Grill, had generated $650.5 million in sales during the same year. By 2012, sales had decreased at Olive Garden. At the final quarter of 2011, sales at established Olive Garden locations had decreased by 2.5%. The Darden president and chief operating officer, said that Olive Garden at that point was "a beloved, but somewhat expected brand". The company introduced a three-course meal for $12.95 to try to stop the decline.
In June 2010, Olive Garden began to import parts of menu formats from its sibling chain, Seasons 52; it began selling smaller dessert portions which it called "dolcini". These new products were modeled after Season 52's "mini-indulgences" product line.
In 2011, Darden announced that it was going to begin co-locating Olive Garden and sibling chain Red Lobster locations. The new restaurants were designed for smaller markets and had separate entrances and dining areas, but unified kitchen and support areas. Menus remained separate, with customers only able to order from the location they are seated in. In 2014, Darden Restaurants announced intentions to sell Red Lobster, to close two Olive Garden and Red Lobster co-locations in Georgia and South Carolina, and to convert the remaining four co-locations into standalone Olive Garden restaurants.
In 2011, Olive Garden implemented a mandatory tip-out program which allowed them to cut more of their employees' hourly wages to $2.13 per hour. In October 2012, Olive Garden became one of the first national restaurant chains to test converting most of its staff to part-time, aiming to limit the cost of paying for health care benefits for full-time employees.
As part of a February 2011, Darden analyst conference, the parent group announced it intended to add more than 200 Olive Garden locations in the following few years. The announcement came after a previous announcement that the company would be expanding into potential new international markets for the chain, including the Middle East and Asia, due to the maturity of the North American market. The company also announced it would begin licensing franchising partnerships, a new direction for the chain and its parent which had traditionally relied on expansion via company-owned locations exclusively.
In the fall of 2013, Olive Garden started a promotion for the "Never Ending Pasta Bowl", where customers can eat all the pasta they want starting at $9.99. During the event, the restaurant served over 13 million bowls of pasta. In 2014, the restaurant continued the promotion but added the "Never Ending Pasta Pass", where customers can eat all the pasta they wanted during a seven-week period for $99. This promotion was limited to the first 1000 people to purchase the pass online. The Pasta Pass promotion has been offered every year since. In 2019, Olive Garden added the "Lifetime Pasta Pass" offered to first fifty diners to sign up for the never ending one. After granted the first pass selectees were then offered the chance to sign up for the second one.
On July 9, 2014, Olive Garden launched a new logo and restaurant design. This included the addition of online ordering and smaller lunch portions.
In September 2014, Starboard Value, an activist hedge fund that had acquired a significant portion of Darden's stock and was challenging Darden's management, released a 294-slide presentation assembled by its founder Jeff Smith, that focused on ways the company was wasting money and failing to satisfy customers. Chief among them was the shortcomings of Olive Garden, which earned considerable media attention. Starboard claimed they justified replacing Darden's directors in an upcoming election with a slate of new directors sponsored by the hedge fund.
In August 2019, Darden responded to false claims that Olive Garden was financing Donald Trump's 2020 presidential campaign, stating: "We don’t know where this information came from, but it is incorrect. Our company does not donate to presidential candidates.” Financial records prove Olive Garden had not contributed to the campaign.
As of February 13, 2022, the company operates 922 restaurants globally.
Olive Garden's original slogan was "Good Times, Great Salad, Olive Garden". This was used when their main advertising focus was unlimited salad. When unlimited soup and breadsticks were added to the menu, the slogan was changed to "When you're here, you're family". The slogan changed in early 2013 to "We're all family here".
