Shake Shack Allergen Menu and Ingredients

The Shake Shack allergen menu tracks eight declared allergens across 154 rows. That total covers 119 finished items across thirteen menu sections, plus a 35-row section of buns, toppings and add-ons. Milk is the allergen declared most often, listed on 113 rows, while egg follows close behind at 85. Reading the item-by-item tables below is the fastest way to check one specific burger, side or topping.

Each row carries the allergens Shake Shack declares for that item. A blank declaration is not an all-clear. Cross-contact risk runs across the kitchen, whatever a single row states.

At a glance

Shake Shack Allergen Menu Item by Item

The Shake Shack allergen menu reproduces the exact wording Shake Shack’s own nutrition and allergen guide uses in every row below. Eight federally recognized allergens appear across the page, led by milk from cheese, shake bases and the potato bun. Most burgers and hot dogs carry that bun. Shake Shack keeps pricing on a separate page rather than mixing it into this allergen-only grid.

Burgers at Shake Shack

The Shake Shack allergen menu declares milk, wheat and sesame on all 25 burgers. That ties to the cheese and the potato bun used across the board. Twenty-one also carry soy, and fifteen carry egg, most often on builds finished with ShackSauce or Herb Mayonnaise. None of the 25 declares nothing at all.

Chicken at Shake Shack

The Shake Shack allergen menu declares wheat on all eight chicken items, from Chicken Shack down to the smallest order of Chicken Bites. Milk turns up on five of them, and egg on four, mostly the Chicken Bites variants sold with dipping sauces. Chicken Shack and Avocado Bacon Chicken alone declare sesame in this section.

Breakfast at Shake Shack

Shake Shack’s breakfast items all declare egg, the only allergen with a perfect record across the thirteen builds. Milk and wheat each turn up on twelve, missing only from Hashbrowns with Sauce. Soy and sesame follow close behind, at eight and ten items.

Flat-Top Dogs at Shake Shack

The Shake Shack allergen menu lists an identical declaration for all six flat-top dogs: milk, wheat and sesame. That ties to the bun and cheese rather than the dog itself. Nothing else appears anywhere in this section.

Fries & Sides at Shake Shack

The Shake Shack allergen menu declares milk on nine of the ten fries and sides. Regular Fries is the only one in the section declaring nothing at all. Wheat turns up on five, mostly the beer-battered and breaded builds. Egg appears twice, on Mac & Cheese and the NYC Late Night Chopped Cheese Loaded Fries.

Sauces at Shake Shack

Shack Sauce and Secret Sauce both declare egg, the allergen to watch across six of the eight bottles. Milk turns up on three. BBQ Sauce is the only one of the eight declaring nothing.

Shakes at Shake Shack

Shake Shack’s shakes all declare milk and egg, the custard base behind every one of the fourteen. Five carry wheat and six carry soy, mostly newer builds like Cookies & Cream and Biscoff Cookie Butter Tiramisu. Dubai Chocolate Shake is the only one declaring tree nuts, and Reese’s Peanut Butter Shake is the only one declaring peanuts.

Floats at Shake Shack

Root Beer Float and Creamsicle Float both declare milk and egg, the same custard base used across the shake list. Neither declares anything beyond those two.

Cups & Sundaes at Shake Shack

Shake Shack’s cup and sundae sizes, single and double alike, all declare milk and egg and nothing else.

Salads at Shake Shack

Caesar Salad and its two variants declare milk, wheat, egg and fish, the only salads carrying all four. Balsamic Vinegar Salad and its two variants clear egg and fish, keeping just milk and wheat.

West Coast Menu at Shake Shack

West Coast Burger and West Coast Chicken Sandwich anchor this section, and milk and egg appear on all seven items in it. Wheat and sesame each turn up on four, tied to the bun on the burger and chicken sandwich, and soy appears on three.

Gluten-Free & Lettuce Wrap Options at Shake Shack

Shake Shack declares milk and egg on all seven items in this section, and six of the seven also carry soy. Wheat turns up on three of the seven, including the Chicken Shack Lettuce Wrap and both Veggie Shack Lettuce Wraps, despite the section’s gluten-free framing.

Drinks at Shake Shack

Shake Shack’s drinks all declare nothing on this list, from the fountain sodas through the coffee and cold brew line.

Buns, Toppings and Add-Ons at Shake Shack

Shake Shack’s final section covers the individual buns, toppings and paid add-ons that build the finished items above, not separate menu items of their own. Sixteen of the 35 components declare nothing, including plain lettuce, tomato, pickle, onion and bacon. Milk appears most often among the rest, on eleven components such as American Cheese and Add Parmesan Cheese, and egg follows on six.

Dairy-Free Options at Shake Shack

The Shake Shack allergen menu lists no milk on 41 of its 154 rows. All seven drink categories clear it entirely. Twenty-four of the 35 buns, toppings and add-ons do too, including plain lettuce, tomato, pickle and both burger and veggie patties. Five of the eight sauces skip milk as well, among them Shack Sauce, Secret Sauce and BBQ Sauce.

Chicken and fries contribute a smaller handful of milk-free items, three chicken items and Regular Fries alone from the fries and sides list. Hashbrowns with Sauce is the lone breakfast item without milk, carrying only egg.

Every burger, hot dog, shake, float, cup, sundae, salad, West Coast item and gluten-free or lettuce-wrap build carries milk without exception. A milk-free order runs through the drinks list, the sauce bar or a handful of standalone toppings rather than any bunned or blended item.

Ordering Gluten-Free at Shake Shack

The Shake Shack allergen menu lists neither wheat nor gluten on 73 of its 154 rows. A dedicated Gluten-Free & Lettuce Wrap Options section covers seven of those builds by name. Each one swaps a gluten-free bun or a lettuce wrap in for the standard potato bun. That applies across the ShackBurger, SmokeShack, Avocado Bacon Burger and Veggie Shack lines.

Wheat clears from every sauce and every drink category beyond that dedicated section. Twenty-eight of the 35 buns, toppings and add-ons clear it too, including the plain Gluten Free Bun and Lettuce Wrap themselves. Nine of the fourteen shakes clear wheat as well, along with both floats and all six cup and sundae sizes.

Burgers, chicken, flat-top dogs and salads carry wheat without exception, tied to the potato bun, breading or croutons in each. The dedicated gluten-free section, the sauce list and the drinks list are the steadiest starting points for a wheat-free order.

Cross-Contact and Shared Equipment at Shake Shack

Shake Shack states that its fries cook in oil shared with the ‘Shroom Burger and Chicken Shack, both breaded items. The fries themselves carry no wheat declaration, but cross-contact remains possible. Shakes carry a separate note on Shake Shack’s own guide. Cross-contact with tree nuts is possible across the whole shake list, tied to limited-time offerings built on tree nuts.

Every order passes through a kitchen built on shared grills, fryers and shake machines. A blank declaration on one row is not a guarantee for a sensitive guest. Shake Shack recommends flagging a serious allergy to a crew member before ordering. A printed guide cannot account for every substitution made at the counter.
