The crispy, fluffy, and buttery dish originated in Texas.A pig stand in Beaumont, Texas, claimed to be the first to invent the dish in 1941 after the restaurant received a thicker slice of bread from a local bakery. As the slice was too big for a toaster, the manager decided to throw the bread in the garbage. But one of the cooks proposed the idea of buttering the thick ends of the bread and grilling it. This is how Texas Toast is believed to have been invented.A similar story was told by another pig stand in Denton, Texas. Chef Wiley W. claimed to have come up with the Texas Toast recipe and also brought a twist to the dish by pairing it with chicken fried steak.The Texas comfort food was part of Top Chef’s Quickfire Challenge.
