The Portobello Mushroom Buttery Jack Returns to Jack in the Box
Jack in the Box has brought back the Portobello Mushroom Buttery Jack for a limited time only. The Portobello Mushroom Buttery Jack was first introduced to the Buttery Jack lineup last summer and it features a 1/4 pound beef patty topped with melted garlic herb butter, Portobello mushrooms, buttery grilled onions, and Swiss cheese. The burger is finished with peppercorn mayo and served on a gourmet signature bun.
