Firehouse Subs Allergen Menu and Ingredients

The Firehouse Subs allergen menu tracks eleven declared allergens across 149 items in eleven menu sections. Milk turns up on more rows than any other allergen, mostly from the cheese, dressings and baked goods layered into each build. Reading the item-by-item tables below is the fastest way to check one specific sub or topping.

Every row states declared allergens and nothing else, exactly as the source lists them for that item. A blank line in the source is never read as an all-clear on its own. Firehouse Subs states only what its own listing declares for that item, and nothing broader.

Firehouse Subs Allergen Menu Item by Item

Every item below keeps the exact wording the Firehouse Subs allergen menu uses for that row. Eleven distinct allergens appear across the page, led by milk from cheese and dressings and wheat from bread and breading. Firehouse Subs keeps its pricing elsewhere, on a separate page rather than mixing it into this allergen-only grid.

Subs at Firehouse Subs

Every one of the 26 Subs declares both milk and wheat, tracing to the cheese and the bread under each build. Engineer carries the widest allergen list of the group, naming eggs, gluten, milk, nitrates, seeds, soy, sulfites, wheat and a fish may-contain note. Veggie carries that same fish may-contain note, tied to the Au Jus Mushrooms topping rather than to any meat.

Meatball runs the shortest list of the 26, limited to gluten, milk, soy and wheat. It also anchors a couple of off-menu builds covered elsewhere on this site.

Kid’s Subs at Firehouse Subs

Five sandwiches make up the Kid’s Subs list on the Firehouse Subs allergen menu, each built from a single filling under bread and cheese. Every one declares gluten, milk and wheat without exception. Kid’s Grilled Cheese and Kid’s Meatball both add soy on top of that base list. Kid’s Ham Sub and Kid’s Turkey Sub add nitrates instead, tracing to the cured meat inside.

Salads at Firehouse Subs

Milk turns up on all eight Salads at Firehouse Subs, the one allergen shared across the whole list. Firehouse Side Salad and the plain Firehouse Salad declare nothing beyond that milk. Firehouse Salad add Salami and the Italian Chopped Salad with Grilled Chicken both add nitrates and sulfites on top, the widest declarations in the group. Firehouse Salad add Ham and add Turkey each add just nitrates.

Salad Dressings at Firehouse Subs

Six dressings round out the Salads section, and two of them, Italian Dressing and Oil & Vinegar, declare no allergens at all. Buttermilk Ranch Dressing carries the widest list, naming eggs, M.S.G. and milk together. Honey Mustard Dressing adds eggs and seeds instead, without any milk. Light Italian Dressing sits between the two, declaring only milk and soy.

Soups at Firehouse Subs

Soups run nine deep once every size is counted separately. Chili is the one entry declaring nothing, at both its 6 oz and 10 oz sizes. Chicken & Dumpling Soup carries the widest list at either size, naming eggs, gluten, milk, soy and wheat together.

Loaded Potato Soup adds sulfites on top of that same base. Tomato Bisque and Chicken Noodle Soup each drop one or two allergens from that list instead.

Sides & Chips at Firehouse Subs

Sides & Chips is the largest single group on the Firehouse Subs allergen menu, spanning 34 separate items from cookies to bagged chips. Twenty-one of those 34 declare nothing at all, covering most of the plain chip bags alongside Chili and the Pickle Spear. 5-Cheese Mac & Cheese carries the widest list of the group, naming eggs, gluten, milk, nitrates, soy and wheat together. Seven items, the Brownie and six cookies, all share that same eggs, gluten, milk, soy and wheat combination.

Sub Bread at Firehouse Subs

Four bread options fill out the Sub Components list. They split evenly between standard and gluten-free rolls. Medium Wheat Sub Roll and Medium White Sub Roll both declare gluten and wheat, nothing more.

Gluten Free Ciabatta Roll carries the widest list instead, naming seeds, sesame and soy. Gluten Free Hoagie Roll runs shortest of the four, limited to seeds alone.

Sub Cheese at Firehouse Subs

Six cheeses fill the Sub Components list. Every single one declares milk and nothing else. Cheddar, Feta, Monterey Jack, Pepper Jack, Provolone and Swiss all carry the identical one-line declaration.

No cheese on this list adds gluten, soy or any other tracked allergen. A milk allergy rules out all six regardless of which variety gets ordered.

Sub Meats at Firehouse Subs

Fifteen proteins make up the meat list on the Firehouse Subs allergen menu. Five of them, Chicken Breast, Oven Roasted Chicken, Seared Seasoned Sliced Beef Rib, USDA Choice Beef Brisket and USDA Choice Roast Beef, declare nothing.

Meatballs carries the widest list by far, naming gluten, milk, soy and wheat together. Tuna Salad is the only meat declaring fish, alongside eggs. Bacon, Pepperoni, Salami and the smoked and cured meats each add nitrates on their own.

Sub Toppings at Firehouse Subs

Eighteen toppings round out the Sub Components list. Ten of them, mostly plain vegetables like Avocado, Cucumber and Tomato, declare nothing at all. Au Jus Mushrooms carries the widest list, naming soy, sulfites and a fish may-contain note tied to its Vegetarian Worcestershire Sauce.

Coleslaw and Creamy Slaw both declare fish outright alongside eggs, unlike the mushroom topping’s weaker may-contain note. Brown Sugar Caramelized Onions is the only topping carrying wheat, from the sugar blend itself.

Sub Condiments at Firehouse Subs

Eighteen condiments and dressings close out the Sub Components list. Four of them, Cajun Seasoning, Garlic Blend, Italian Salad Dressing and Sweet Baby Ray’s BBQ Sauce, declare nothing at all. Garlic Mayonnaise carries the widest list, naming eggs, gluten, seeds and wheat together.

Captain Sorensen’s Datil Pepper Hot Sauce, Jerk Mustard and Sweet Mustard each declare fish, the only three condiments on the list that do. Most of the remaining mustards and mayonnaises are limited to eggs, seeds or soy alone.

Dairy-Free Options at Firehouse Subs

Milk does not appear in the declared list for 79 of the 149 items on the Firehouse Subs allergen menu. Sides & Chips contributes the largest share, with 22 of its 34 items clear of milk, mostly the plain chip bags and fries. Sub Components adds most of the rest, led by 14 of the 15 meats and 16 each of the toppings and condiments. All four bread rolls qualify too, alongside four of the six Salad Dressings.

None of the 26 Subs, the five Kid’s Subs or the eight Salads qualify. Cheese or a milk-based dressing sits on every one of those builds instead. All six Sub Components cheeses carry milk by definition, whatever the variety. A guest avoiding dairy is better served building from the Sub Components list directly than ordering a named sandwich as printed.

Ordering Gluten-Free at Firehouse Subs

Wheat does not appear in the declared list for 95 of the 149 items on the Firehouse Subs allergen menu. That is the largest of the two dietary groups covered on this page. Every Salad and every Salad Dressing qualifies, since neither bread nor a breaded topping touches either list.

Two of the four bread options break from the rest of that group. The Gluten Free Ciabatta Roll and Gluten Free Hoagie Roll both skip wheat, unlike the two standard sub rolls beside them. Sides & Chips contributes 22 more, mostly plain chips, fries and the Chili.

None of the 26 Subs or the five Kid’s Subs qualify as printed, since a standard wheat roll sits under every one of those builds. Ordering on a Gluten Free roll instead removes the wheat, though the roll itself still carries seeds and, on the Ciabatta version, sesame. Fourteen of the 15 Sub Components meats and most of the toppings and condiments round out the list, unaffected by bread at all.

Cross-Contact and Shared Equipment at Firehouse Subs

The Firehouse Subs allergen menu still assumes a kitchen that runs on shared counters and shared equipment. A menu item made without a declared allergen can still pick one up through cross-contact with whatever else is moving through the same line. Bread rolls, meats and cheeses are sliced and toasted on shared boards and ovens behind the same counter.

A sandwich built to avoid one allergen can still meet it through contact with another during assembly. Telling a team member about a serious allergy before ordering covers what the Firehouse Subs allergen menu cannot. Prep and ingredient sourcing can vary from one location to the next.
