In-N-Out Allergen Menu and Ingredients

In-N-Out keeps one allergen chart for the whole menu, and thirty-one items sit on it. Four allergens do all the work: milk, wheat, egg and soy. The chart’s own wording runs through the tables below, so a cell reads Milk & Milk Products rather than plain milk. The Contains column stays empty on fourteen rows.

Protein Style swaps the bun for hand-leafed lettuce, and the chart treats each of those builds as its own row. Wheat vanishes with the bun. The In-N-Out allergen menu therefore splits into bunned and bunless versions of the same six burgers, which is unusual for a chain this small.

In-N-Out Allergen Menu Item by Item

Declarations on the In-N-Out allergen menu follow the build rather than the counter, so a cheeseburger and a Double-Double read identically. Both carry milk from the cheese slice, egg from the spread, wheat from the bun and soy. The Double-Double differs on patty count alone. Ordering mustard and ketchup instead of spread drops the egg.

The Contains column names what an item declares outright, and nothing more. Shared fryers, shared blenders and shared preparation surfaces sit outside it, and the cross-contact notes further down cover that ground in detail. Readers comparing builds against the priced menu will find the same item names on both pages.

In-N-Out Burger Allergens

Twelve burger rows cover three builds in four states each: standard, spread-free, Protein Style and both changes together. Milk arrives with the cheese slice, which is why the plain hamburger skips it. Egg traces to the spread. Soy Products run through eleven of the twelve rows.

In-N-Out French Fries Allergens

French Fries take the simplest row on the chart, declaring none of the eight allergens tracked. The fries section holds a single item. Eight allergens sit on that chart, counting fish, shellfish, peanuts and tree nuts alongside the four that actually appear, and fries clear every one.

In-N-Out Shake Allergens

Three shakes carry milk, and the Chocolate Shake adds soy on top of it. Vanilla Shake and Strawberry Shake declare milk alone. Neither wheat nor egg reaches the shake line on the In-N-Out allergen menu, which separates these three from most chain shakes.

In-N-Out Drink Allergens

Fifteen drink rows run from Coca-Cola to Creamer, and twelve of them declare nothing. Hot Cocoa carries milk and soy, while plain Milk and Creamer carry milk on its own. Marshmallow Packet, Sweet Tea, Iced Tea and Coffee sit in the empty column. Both root beers join them.

Dairy-Free Options at In-N-Out

Seventeen items on the In-N-Out allergen menu skip Milk & Milk Products, and the plain hamburger leads them. Protein Style hamburgers, the spread-free hamburger and the plain hamburger all clear dairy, since the cheese slice never joins them. Every cheeseburger and every Double-Double declares milk, cheese slice included.

French Fries and twelve drinks fill out the rest of the dairy-free count. Coca-Cola, Diet Coke, 7UP and Dr Pepper open that list. Both root beers, Pink Lemonade, Minute Maid Zero Sugar Lemonade, Sweet Tea, Iced Tea and Coffee close it, with the Marshmallow Packet alongside. The table below shows what those seventeen still declare.

Ordering Gluten-Free at In-N-Out

Twenty-five items on the In-N-Out allergen menu skip Wheat/Wheat Gluten, and Protein Style accounts for the shift on the burger side. Removing the bun removes the wheat. Protein Style rows drop that declaration and keep whatever the cheese and spread bring.

Hamburger Protein Style with mustard and ketchup ends up the one burger row declaring nothing at all. Bunless is not the same as wheat-free. Six burger rows, French Fries, three shakes and all fifteen drinks make up the twenty-five. None of this removes wheat from the kitchen, and the off-menu builds carry the same bun question.

Cross-Contact and Shared Equipment at In-N-Out

Buns in Arizona, California, Idaho, Nevada, Oregon, Utah and Washington come from a facility where sesame is present. In-N-Out footnotes that on its current chart. The Contains column stays as In-N-Out publishes it, because a facility note describes the plant rather than the recipe. Anyone avoiding sesame should raise it with the associate before ordering.

One fryer handles the potatoes and nothing else, since In-N-Out fries no breaded product. Shakes run through shared blenders, so a vanilla order can follow a chocolate one through the same equipment. In-N-Out publishes its chart as a guide, and the counter can confirm a build before it goes on the grill. The Double-Double and the hamburger share one grill.
