Slater’s 50/50 Debuts Two New Shroomin’ Onion Burgers

Slater’s 50/50, the popular meat-centric gastropub concept best known for creating the Original 50/50 burger patty made with 50% ground bacon and 50% ground beef, has introduced two new menu items that will be available through June 30, one of which is a completely vegan burger. Earlier this year, Slater’s 50/50 launched a rebranding effort to change consumers’ perceptions of the brand and focus more squarely on showcasing their culinary prowess outside of burgers, bacon, and beer. Slater’s 50/50 sees the new vegan burger option as a way to continue delivering on that promise of masterfully transforming plant-based ingredients into inconceivable, outrageous, and uniquely ‘slaterized’ dishes that still pack a punch of flavor.

The Vegan Shroomin’ Onion Burger is made with two umami-marinated portobello mushrooms, topped with sautéed mushrooms, caramelized onions, crispy onions, roasted red peppers, vegan garlic aioli, pickled jalapeños and arugula on vegan bun. It’s meatier counterpart, the 50/50 Shroomin’ Onion Burger, features Slater’s signature 50/50 beef and bacon blend patty topped with sautéed mushrooms, crispy portobello mushroom, caramelized onions, crispy onions, roasted red pepper, chipotle mayo, smoked gouda and arugula on brioche bun. Both burgers are priced at $14.99.

Both the Vegan Shroomin’ Onion Burger and 50/50 Shroomin’ Onion Burger will be available through June 30 at all California, Nevada, and Texas locations. Slater’s 50/50 is owned by Los Angeles-based Elite Restaurant Group, a multi-concept operator that also owns Daphne’s and Patxi’s Pizza.
