Here’s how to eat Firehouse Subs keto style! 

Firehouse Subs offers a very helpful nutrition calculator when you’re eating keto. I love it because they give you macros for most of their menu options, so you don’t have to keep a calculator on hand. The best thing about eating keto at Firehouse Subs? You can make any sandwich into a salad (in addition to their regular salads), which gives you easy options for ordering.

We hope this Firehouse Subs keto dining guide will help you plan your next meal when dining there.

The basics of successful Firehouse Subs keto ordering:

  • Stick with subs in a bowl or salads.
  • Avoid bread, flatbreads, wraps, cookies, and chips.
  • When in doubt, leave dressings and toppings out.
  • For drinks, stick with water, unsweetened iced tea, or Diet Coke products.
  • Download the free app for amazing deals: iPhone or Android.

Not feeling either of those?

You’ve got plenty of options since any Firehouse Subs sandwich can be made into a keto salad. Please note you’ll want to stay away from tuna salad, meatballs, and chicken breast (go for oven-roasted chicken instead), as those pack larger amounts of carbohydrates.

    Just curios am I missing something about leaving mayo off everything

    • Amber (Hip Sidekick)

      Hi there! We do mention “no mayo” above for the top option. We also have this noted in the tips – “When in doubt, leave dressings and toppings out.” Hope that is helpful!

  2. Nick

    How’s the Turkey Bacon Ranch with Pepperjack Salad Bowl?

    • Amber (Hip Sidekick)

      Hi Nick! It appears for that option, if wanting to stay keto, you’d hold the mayo and dressing. Hope that helps!
