Firehouse Subs – A Custom Build for Dairy-Free & Gluten-Free Lunch


Eat Dairy Free - Your Essential Cookbook for Everyday Meals, Snacks, and SweetsUpdated 2021! Firehouse Subs  is a fast casual sandwich shop with more than 1000 locations across the U.S., Canada, and Mexico. The allergen menus for the U.S. and Canada appear to be the same, so our list below is for North America as a whole. And yes, this chain was founded by former firefighters! In fact, the founders later started the Firehouse Subs Public Safety Foundation to help provide life-saving equipment to first responders.

Other Allergen Notes

  • At our time of review, all of the Firehouse subs and salads contained dairy when prepared by the menu. But in most cases, you just need to order it without cheese. Most of their breads, meats, dressings, and condiments are made without dairy (see lists above!). Which means you can simply order most of their subs from the menu without cheese.
  • Take note that the Light Italian Dressing contains dairy, even though the regular Italian Dressing is dairy-free. Their Italian Seasoning and Meatballs also contain dairy.
  • For gluten-free diners, they now have a gluten-free sub roll (Schar brand)! It’s pictured below (all of their sub photos have cheese on them, so you’ll have to use your dairy-free imagination!). Their Chopped Salads are also a great gluten-free option. All of the dairy-free salad dressings noted above appear to be gluten-free, too.

Certain stuff on their menu one might think doesnt have dairy has dairy such as their meatballs. Found out the hard way tonight. Luckily Im not terribly allergic. I even called out I have a dairy allergy and the employee didnt say anything about it. They also didnt change knives so I found cheese in the cut as well.

    Firehouse is always accommodating to my daughter’s dairy allergy. We love how we can watch them make her sandwich. One thing I’d like to mention. Always ask them to change gloves and get a clean knife before preparing the sub. They will always comply with the request. They don’t normally change gloves btwn subs so there’s a good chance their gloves have dairy on it since the subs are steamed, the cheese is always melted and they grab the subs to cut it in half and then wrap them. So lots of handling with the gloves from one sub to another. They also don’t wash the knife btwn subs. They do wipe the knife quickly,, but someone who is severely allergic to dairy might react if a new knife isn’t used. Hope this helps!

  2. I am allergic to garlic and it is not on the allergen list. Do you sauté your steak and the onions in garlic?
