Most Common Allergens Found In Ingredients

Shake Shack includes several FDA-recognized food allergens in many of its menu items

  • Wheat (gluten) in buns, breadcrumbs, crispy onions, etc.

  • Eggs in shakes, sauces, and burger buns.
  • Soy and Nuts in sauces, burger components, cheese, etc.

Allergen Free Menu (By Category)

Burgers & buns options

  • Buns: The standard Martin’s Potato Roll is typically listed with milk, wheat, and sesame. If you avoid any of these, ask for a Gluten-Free Bun or Lettuce Wrap.
  • Beef patty: The classic patty itself doesn’t usually carry top allergens. Cheese adds milk; sauces can add egg and/or soy depending on your choice. A ShackBurger’s full listing often reflects milk, egg, soy, sesame because of cheese, sauce, and bun.

Chicken & hot dogs

  • Chicken items (sandwiches, bites) are commonly breaded/fried, so expect wheat, and sometimes milk/egg depending on build and sauce.
  • Flat-top dogs are served on a bun; expect wheat/sesame at minimum—check toppings if you’re avoiding milk or soy.

Fries & sides

  • Regular Fries don’t typically list a major allergen on their own; Cheese Fries add milk.
  • Important: Fryer practices can vary. Ask whether fries share a fryer with breaded items. If you’re celiac or highly sensitive, confirm before ordering.

Shakes, frozen custard & sweets

  • All shakes and custard contain milk and egg. Some flavors (like cookie-based options) may include wheat. Limited-time shakes or mix-ins can raise tree-nut cross-contact concerns—ask first if you’re sensitive.

Sauces & dressings

  • Cheese & cheese sauce: Milk.
  • Mayo-based sauces/dressings: often egg; some also list milk and/or soy. Check the specific sauce you plan to use.

Smart ordering tips

  • Gluten/wheat-avoidant: Choose a Gluten-Free Bun or Lettuce Wrap; avoid breaded chicken; verify fryer setup if you want fries.
  • Dairy-avoidant: Skip cheese/cheese sauce; confirm sauces; shakes/custard contain milk and egg.
  • Egg-avoidant: Avoid mayo-based sauces and shakes/custard; pick a sauce that fits your needs.
  • Sesame-avoidant: Standard buns list sesame—choose the Gluten-Free Bun or Lettuce Wrap.
  • Nut concerns: Standard items generally don’t use peanuts, but supplier/facility cross-contact can occur. Limited-time desserts or shake mix-ins may involve tree nuts—confirm in-shop.
