Celebrate smashburger® day with the modern founding fathers of smash
Celebrate National SmashBurger® Day at the birthplace of the iconic smash burger itself. This holiday is all about honoring the best smashburger around, and our Buy One, Get One FREE (BOGO) offer delivers unparalleled value on pure, unadulterated burger bliss.
There is a science to why our burgers taste better. We take fresh, Certified Angus Beef® and smash it hard on a sizzling-hot grill to lock in a rush of savory juices while creating those signature crispy, caramelized lace edges that burger lovers crave. Our expansive menu pairs Certified Angus Beef® patties with premium toppings. And the best part about celebrating National Smashburger® Day at the OG smashburger joint is that you don't have to choose just one.
National Smash Burger Day 2026 FAQ's
How do I redeem the National Smash Burger Day deal online or in the app?
To unlock your free burger, you need to add both eligible burgers to your cart before checking out. Once both are in your cart, apply the promo code PLACEHOLDER (or tap the offer in your account), and the price of the second burger will drop to $0!
Can I mix and match different burgers, or do they have to be identical?
You don't have to get two of the exact same burger when using the BOGO offer. Just keep in mind that the equal or lesser value item will be the one marked as free.
Can I use this BOGO deal on DoorDash, UberEats, or third-party delivery?
This exclusive National Smashburger Day deal is only available when you order directly through the official Smashburger App, Smashburger.com, or in-person at a participating restaurant. It cannot be redeemed on third-party delivery services.
Does the BOGO offer apply to customizations and premium toppings?
The base price of your second burger is completely free! However, if you add premium upgrades to your free burger—like extra bacon, fresh avocado, or a double patty upgrade—those add-on costs will still apply to your final total.
Is there a limit to how many free burgers I can get on National Smash Burger Day?
There is a limit of one free burger per order/transaction. However, if you are feeding a crowd, you are welcome to place a separate order or visit us in-store to grab another round!
