Jack in the Box Brings Back the Portobello Mushroom Buttery Jack

The Portobello Mushroom Buttery Jack returns to Jack in the Box for a limited-time at participating locations.

The burger consists of a quarter pound signature beef patty with melted garlic herb butter, Portobello mushrooms, Swiss cheese, peppercorn mayo, grilled onions, and a signature bun.

The price tag on the Portobello Mushroom Buttery Jack is $4.99 (may vary) for just the burger and $6.69 for a combo that includes the burger, fries, and a fountain drink.

You can check out my previous review of the Portobello Mushrrom Buttery Jack here.

Expect the burger to stick around until the end of July.
