While nobody can say who first thought of spreading avocado on toast, the modern avocado toast trend began in the 1990s at a restaurant called Bill's in Sydney, Australia.
Avocado made a jump to cultural sensation thanks to Gwyneth Paltrow's 2013 cookbook which included an avocado toast recipe, claiming it was the food she made most often.
Food bloggers picked up on it, and it took off from there. The rise of Instagram in the 2010s only further fueled the food's reputation, and the demand for avocados skyrocketed.
Now, the online community's view on avocado toast has shifted. The dish represents "bougie" culture, perceived as overhyped, overpriced, and more about trendiness than substance.
