Last Update in July 2022! Some fast casual chains have scaled back in recent years, but Smashburger is aggressively expanding. They’ve also made some bold strategic moves, like opening a location with a full bar and adding dairy-free milkshakes to their menu nationwide. Yes, you can now order a vegan milkshake in Vanilla, Chocolate, Strawberry, Peanut Butter, Tangerine Dream, or Oreo! They’re made with Eclipse dairy-free ice cream, and sold at Smashburger’s 200+ location in the United States. As for the food, we’ve outlined the dairy-free options below, and have also included a separate vegan menu guide.
Smashburger Dairy-Free Menu Guide with Allergen Notes & Vegan Options
Be aware of special order requirements in parentheses () next to the menu items, and see the Heads Up notes to help fill in the blanks. Please note that this guide is for the U.S. locations. Options may vary in other countries. In fact, Smashburger restaurants in the UK have many more dairy-free and vegan options!
Heads Up! Smashburger lists all of their burger buns AND their grilled chicken, beef, turkey, and veggie patties as containing milk. Not all of the items contain milk, but they are cooked with butter. If you are okay with potential cross-contamination on the grill (please note that the fryer and shake station also have cross-contamination risk), then you can order select burgers and sandwiches with “no butter.” Check at your local Smashburger for more options if you are not concerned with potential cross-contamination, and for safety with any menu items if you are concerned.
Other Allergen & Dietary Notes: All items noted below are egg-free, nut-free, and peanut-free, unless otherwise noted. For vegan options, see the Vegan Menu Guide at the bottom of this post.

Delicious food, but they put Reece's Pieces in my dairy free shake
I don’t know if it was because we were such a big group and she was flustered, or if this is an actual issue, but my PB shake was made with Reece’s Pieces which contain dairy. She happily took it back and replaced it, but didn’t seem to “;get” the issue. Still, the service and food were outstanding, and I really enjoyed my Oreo dairy free shake, just want everyone to be aware if they order Peanut Butter flavor.
