The calorie count is not a single number but a spectrum, influenced by everything from the type of bread to the choice of toppings.

The Calorie Breakdown by Sub Size

Jersey Mike's offers their Philly steak sandwich, known as the #17 Steak Philly, in multiple sizes and formats, each with a distinct calorie total. The size of the sub is the most significant determinant of its caloric value, with larger subs containing more meat, cheese, and bread.

Regular Size (#17 Steak Philly)

A regular-sized #17 Steak Philly sub is typically served on a 7-inch bun. The nutritional content varies slightly depending on the bread choice:

On White Bread: A regular sub on white bread contains approximately 640 calories, including the standard provolone cheese and seasonings.
On Wheat Bread: The wheat bread option for a regular sub has a slightly higher calorie count, around 730 calories.

Giant Size (#17 Steak Philly)

The giant sub is a larger, 14 to 15-inch version, effectively double the regular size. The calorie count reflects this substantial increase:

On White Bread: A giant sub on white bread can contain around 1,189 to 1,440 calories, with some variations in reporting.
On Wheat Bread: A giant sub on wheat bread is listed at approximately 1,270 calories.

The 'Philly in a Tub'

For those seeking a low-carb alternative, Jersey Mike's offers the "Sub in a Tub" option, where the sandwich fillings are served in a bowl instead of on bread. The #17 Steak Philly in a tub is a much lighter option, with around 440 calories. This is an excellent choice for anyone following a keto-friendly or low-carb diet.

How Customization Changes Calorie Count

Beyond the base sub, several customization options can alter the final calorie count. The standard #17 comes with grilled onions and peppers, but other additions can stack up quickly.

Cheese: While provolone is standard, additional cheese will add more calories and fat.
Sauces and Condiments: Adding extra oil, mayonnaise, or other signature sauces like the chipotle mayo can significantly increase the total calories and fat content. For example, a regular sub "Mike's Way" includes spices, lettuce, tomatoes, and a blend of olive oil and vinegar. This is different from the hot sub build, so specifying your condiments is important.
Extra Meat: Ordering extra steak will obviously increase the protein and fat content, raising the total calorie count.
