Summary of Gluten Free Menu Options at Smashburger

Pro tips and a quick summary of everything gluten free at Smashburger.

When you order at the restaurant or on the app for delivery/pickup, tell them you have an allergy or Celiac Disease so they take precautions with your food.
Smashburger has a ton of options! You can get burgers, grilled chicken sandwiches, and even turkey sandwiches with a ton of toppings. The fries are also gluten free, but there is a small risk of cross contamination in the fryer so keep that in mind.
Smashburger has over 200 ratings on Find Me Gluten Free with an average of 4 stars! Many of the reviews mentioned they did not get sick and the food was safe and tasty. A few people mentioned locations without dedicated fryers, so ask at the store! You also may want to avoid shakes if you have Celiac Disease or an allergy, as some ingredients come from factories that process wheat/gluten.
Personal experiences here are positive. I recently went to Smashburger and got the Double Bacon Smashburger on a gf bun with Smash Fries. It was delicious and very filling without any cross contamination.
