Cooking with Chefs: Lowell Burger Company

One of chef Nick Speros’ earliest food memories is of his Greek grandmother cooking for him, his two brothers and all the neighborhood kids in Cambridge. If one of Speros’ friends didn’t like it, she would say, “Eat or get out.” That’s where his love of cooking began, and learning in such an environment “taught me food can be very nurturing, loving and satisfying in so many ways,” he says. 

Early in his career, Speros worked at various restaurants as a waiter and bartender before taking a job at Mirabelles Café & Bakery in Boston, where the chef encouraged him to attend culinary school. 

While working for Boston-based Project Bread, a nonprofit that addresses child hunger, he met his business partner, Tobias Marx. Together, they opened Lowell Burger Co. 

While he was growing up, Speros’ family would eat traditional Greek food around the holidays. As the years went on, Speros’ cooking became increasingly unconventional. One of his favorite Thanksgiving dishes was braised pork shoulder and deboned turkey thighs, rolled up and basted in apple cider and maple syrup. “It was so desperately untraditional,” he says, recounting how the turkey thighs were like candy.

To highlight the balance between tradition and innovation, Speros has shared his aunt’s heretofore secret recipe for Greek meatballs, along with a variation on Lowell Burger Co.’s famous Greek Boy — a mouthwatering burger made with lamb and mint.

Salt and ground black pepper
1/4 red onion, thinly sliced
24 ounces ground lamb
