From May 1 to June 1, 2025, Shake Shack is offering a different single burger for FREE with a $10 minimum purchase at participating locations. The offer excludes all paid add-ons such as extra avocado or bacon.

Here’s what burger is available each week:

  • May 1 to 11, 2025SmokeShack 
  • May 12 to 18, 2025Bacon Cheeseburger 
  • May 19 to 25, 2025Avocado Bacon Burger

The offer is only valid for purchases placed at a kiosk in-restaurant or for delivery or pick-up via the Shake Shack app or at shakeshack.com. Use promo code BURGERMONTH at checkout. (Note: Promo code must be entered in ALL CAPS.)

Limit one offer per order — with a maximum savings equal to the price of each week’s promotional burger (from $8.49 to $11.49). If you have a large order, consider breaking it up into separate transactions for the best savings. 

You must add at least $10 worth of food and/or drinks to your order, excluding the cost of the complimentary burger. (Gift card purchases are also excluded.)
