Gluten-Free Sub Rolls & Sandwich Preparation
Firehouse Subs offers certified gluten-free sub rolls at participating locations nationwide (usually supplied by Schär). These rolls are individually wrapped to prevent contact with wheat flour before toasting.
When ordering a gluten-free sub, request that the staff change their disposable gloves, wipe down the preparation counter, and place clean parchment paper under your sandwich in the toaster and steam cabinet.
Most whole-muscle deli meats—including USDA Choice roast beef, smoked turkey breast, and honey ham—do not contain gluten ingredients. However, certain specialty meats like Italian meatballs containing wheat breadcrumbs must be strictly avoided.

The Evolution of Gluten-Free Bread at Firehouse Subs
Until the mid-2010s, dining at submarine sandwich shops was virtually impossible for individuals diagnosed with celiac disease or severe gluten intolerance. Sub shops are flour-heavy environments where bread baking, slicing, and crumb shedding are continuous throughout the day.
Recognizing this unmet customer need, Firehouse Subs partnered with Schär—the global leader in certified gluten-free baking—to introduce dedicated, individually wrapped gluten-free sub rolls across nationwide locations. These rolls are baked off-site in certified gluten-free bakeries, flash-frozen, and shipped directly to restaurants in tamper-evident plastic sheaths.
This packaging ensures that the bread itself remains completely sterile and free from airborne flour particles until the kitchen crew opens it specifically for a customer order.
How to Safely Order Gluten-Free at Firehouse Subs: 5 Golden Rules
Saying 'I am celiac' or 'I have a wheat allergy' triggers mandatory commercial kitchen procedures. The crew will recognize that this is a medical requirement rather than a lifestyle preference, enforcing rigorous cross-contact prevention.
The assembly crew must strip off existing gloves, wash hands with warm soapy water for 20 seconds, and lay down fresh parchment paper over the sandwich preparation station. If you do not see this happen, politely request a fresh glove change.
To prevent contact with gluten crumbs inside the commercial toasting oven, your gluten-free sub roll must be placed on its own parchment sheet before sliding through the toaster heat chamber.
Never order the Meatball sub (breadcrumbs contain wheat), French Dip (Au Jus contains wheat thickeners), or Teriyaki Chicken (soy sauce contains wheat). Stick with whole-muscle turkey, ham, roast beef, or brisket.
When handed your order, verify that the sandwich wrapper has the distinct 'Gluten-Free' sticker or colored inspection tape applied by the shift supervisor before leaving the counter.
Cost Comparison: Gluten-Free Rolls Across Fast-Casual Brands
Certified gluten-free grains (millet, rice, tapioca) are substantially more expensive to source and mill than commodity wheat flour. Firehouse Subs charges an average upcharge of $1.75 to $2.25 for a Medium gluten-free sub roll. This aligns closely with industry averages at Jersey Mike's (+$2.00) and Subway (+$1.75 in test markets).
Notably, Firehouse Subs does not charge extra if a diner chooses to order their sub 'In a Bowl' over lettuce rather than requesting a specialty roll, providing an economical zero-gluten alternative for budget-conscious diners.
