The History of Sub in a Tub
The Sub in a Tub began as a clever workaround for diners at Jersey Mike’s who wanted to enjoy a hearty sandwich without the added carbs. Originally designed for those following low-carb or gluten-free diets, this variation soon became popular with a broader audience looking for lighter, healthier alternatives to traditional sandwiches.
In its simplest form, the Sub in a Tub includes all the ingredients you’d expect from a sub—like meats, cheeses, and fresh veggies—served in a bowl rather than on bread. The concept is now widespread, with many delis and sandwich shops offering their own breadless versions.
Why has this dish become so popular? In part, it’s because of the rise of the keto diet, which emphasizes high-fat, moderate-protein, and low-carbohydrate meals. For keto dieters, eliminating bread is one of the simplest ways to reduce carb intake while still enjoying flavorful, satisfying meals. The Sub in a Tub fits perfectly into this approach and offers endless possibilities for customization.
