Understanding the Shackburger's Components

To calculate how many calories in a Shackburger without bun, we must first break down its standard ingredients. The classic Shackburger includes a beef patty, a slice of American cheese, lettuce, tomato, and a helping of signature ShackSauce. The biggest source of carbohydrates and a significant portion of the total calories comes from the non-GMO potato bun. By ordering your Shackburger "bunless" or in a lettuce wrap, you eliminate a substantial amount of the total intake.

Single Shackburger Without the Bun

When you remove the 180-calorie potato roll from a standard Single Shackburger, the nutritional profile changes dramatically,. The total calorie count drops from 500 to approximately 320, making it a highly appealing option for those following a low-carb or ketogenic diet.

Single Angus Beef Patty: 190 calories, 12g fat, 19g protein
One slice of American Cheese: 70 calories, 6g fat, 4g protein,
ShackSauce™: 60 calories, 6g fat,
Lettuce & Tomato: Less than 10 calories combined

Double Shackburger Without the Bun

For those needing a more substantial, protein-packed meal, the Double Shackburger without the bun is a great alternative. This modification involves adding a second beef patty, which essentially doubles the meat's contribution to the total nutrition. The result is a filling burger with a moderate increase in calories and a high protein count.

Two Angus Beef Patties: 380 calories (190 x 2)
One slice of American Cheese: 70 calories
ShackSauce™: 60 calories
Lettuce & Tomato: Less than 10 calories

By following this approach, a Double Shackburger without the bun contains roughly 520 calories, with 36 grams of fat and an impressive 42 grams of protein, while keeping net carbs at just 3g. This is an excellent, filling option for those on a keto diet.

Customizing Your Bunless Burger

Ordering without the bun is just the first step. To further control your macros, Shake Shack offers several customizable options. You can opt for a lettuce wrap or remove the cheese or sauce to decrease calories and fat even more. Some common additions like bacon are relatively low-calorie and fat-friendly.
