North Shore Three-Way

The North Shore Three-Way is a regional sandwich originating in the North Shore area of Massachusetts, most famously associated with the roast beef sandwich tradition. This specific rendition is prominently served at Sam LaGrassa's in Boston, as highlighted by the food channel Only Scrans. The sandwich typically consists of thinly sliced roast beef, a generous layer of American or cheddar cheese, and a tangy barbecue sauce—often the James River brand—all piled onto a soft, split-top bun. Some variations add mayonnaise or horseradish, but the core three components are beef, cheese, and sauce.

What distinguishes a great North Shore Three-Way is the quality of the roast beef: it should be rare, tender, and hand-sliced to maintain its texture. The cheese must be melted just enough to bind the ingredients, while the sauce should provide a sweet-and-smoky counterpoint without overwhelming the beef. The bun, ideally griddled or steamed, must hold the filling without becoming soggy. Sam LaGrassa's execution, as noted by Only Scrans, exemplifies this balance.

Regional variations exist across the North Shore. Some outlets, like Kelly's Roast Beef, offer a "three-way" that includes horseradish or a different sauce blend. Others substitute cheddar for American cheese. The dish remains a staple of Massachusetts diner and deli culture, with each venue adding its own twist while honoring the classic three-part formula.
