Photo: Hardee'sMushroom & Swiss Thickburger
The Thickburger for people who want savoury rather than salty. Sautéed mushrooms and melted Swiss cover the thick Angus patty, and together they make something closer to a steakhouse burger than a drive-thru one. Rich, earthy and quietly one of the best things on the menu.
The story
The Thickburger line was Hardee’s answer to years of falling sales. In April 2003, under CKE chief executive Andrew Puzder, the chain dropped its jumble of cheap burgers and relaunched around thick Angus beef patties of up to two-thirds of a pound, sold on the idea that bigger and better was worth paying for. The Mushroom & Swiss was one of the burgers in that family. It has outlived the name itself: Hardee’s now sells its line-up as charbroiled burgers, and this one survives as the Mushroom & Swiss.

About Hardee's
Wilber Hardee opened his first restaurant in Greenville, North Carolina, in 1960, and Hardee’s became a Southern institution largely thanks to something it started making in 1977: biscuits made from scratch every morning. In 1997 it was bought by the company behind Carl’s Jr., so the two chains share a star logo and several burgers, but Hardee’s has kept its own, more family-friendly personality.
