Popular Menu Items and Allergen Information

To give you a clear view of what to expect, here’s an overview of how major allergens are managed in popular Smashburger menu categories:

  1. Burgers
    • Smashburger’s patties, made from certified Angus beef, are generally free from gluten and dairy. However, toppings and buns often introduce allergens.
    • Common allergens like dairy are present in many toppings (like cheese and buttered buns). Gluten is present in most bun choices, except for the gluten-free option.
    • Veggie burgers often contain soy and gluten, so customers with these allergies need to inquire further.
  2. Chicken Sandwiches
    • The chicken patties used in Smashburger sandwiches are typically dairy-free, but the breading may contain gluten, and some preparations include soy or eggs.
    • For a gluten-free option, customers can request a lettuce wrap in place of a bun. However, note that these are prepared in the same area, and cross-contact with gluten-containing ingredients is possible.
  3. Salads
    • Salad bases are usually free of major allergens, but toppings and dressings can vary.
    • Dressings and add-ons like cheese and croutons introduce allergens like dairy, soy, and gluten. Always check the allergen menu, as some salads may have egg-based dressings or nut toppings.
  4. Fries and Sides
    • Fries are typically dairy- and gluten-free but are prepared in shared fryers, so cross-contact with other allergens (like gluten from battered items) may occur.
    • For sides like fried Brussels sprouts, onions, or tots, it’s important to note that they may contain soy or gluten depending on their preparation.
  5. Kids’ Menu
    • Items like chicken strips and fries are popular choices for kids, but they can contain allergens like gluten and dairy.
    • It’s advised to verify ingredient lists, as kids’ items often have fewer options for substitution.
  6. Shakes and Beverages
    • Smashburger’s shakes are dairy-based and usually contain additional allergens like soy and gluten, depending on flavors and toppings.
    • Most soft drinks are allergen-free, but flavored shakes may contain cross-contact risks due to shared equipment.
