Yes, Firehouse Subs has introduced French fries, with Original and Cajun versions now appearing at participating restaurants. The fries are being rolled out gradually, so availability can still vary from one location to another.
The addition is notable because Firehouse Subs has traditionally been known for its hot and cold subs, along with sides such as chips, chili and soup. The new fries give customers another side option without changing the chain’s main focus on sandwiches.
Do Firehouse Subs Have French Fries Now?
Firehouse Subs does have French fries now, but they are not yet available at every restaurant. The chain is introducing them across its U.S. and Canadian locations in stages.
The new menu includes Original French Fries and Cajun French Fries. Firehouse’s online menu describes the regular fries as golden and crispy on the outside with a fluffy center, while the Cajun version is tossed in Cajun seasoning.
According to Allrecipes’ report on the rollout, the fries were available at about 60% of Firehouse Subs restaurants when the item was introduced. The company planned to expand that coverage to roughly 80% by the end of 2026 before eventually reaching all U.S. and Canadian restaurants.
That means seeing fries on one restaurant’s menu does not necessarily mean they are available at every Firehouse location. If you enjoy trying unique fast-food flavors, check out our Round Table Pizza Dr Pepper BBQ Pizza for another sweet and smoky menu creation.
What Are the New Firehouse Subs French Fries Like?
The new fries have a ridged “tin roof” cut that gives them a thicker shape and a textured surface. The design is intended to provide a crisp exterior while keeping the inside soft and fluffy.
The ridges also have a practical purpose: they create more surface area for seasoning to cling to. That is particularly noticeable with the Cajun version, where the seasoning sits in the grooves of the fries.
The Original French Fries are the simpler choice, with a traditional salty potato flavor. The Cajun French Fries use the same general style but add Cajun seasoning for a more pronounced savory kick. Firehouse’s menu currently lists the regular fries at 420 calories and the Cajun fries at 550 calories.
How Does Firehouse Subs Make Its French Fries?
Firehouse Subs has not published a complete recipe or detailed cooking process for its fries. What is known is that the fries use a ridged cut and are prepared to have a crisp outside and fluffy interior.
So, claims about an exact cooking temperature, oil blend or preparation method would go beyond the information Firehouse has made public.
The unusual cut is one of the clearest details available about the fries. Besides creating their appearance, the ridges help hold seasoning and contribute to the texture.
What Is the Most Ordered Sandwich at Firehouse Subs?
The Hook & Ladder is currently listed as the most popular Firehouse Subs menu item by one menu-tracking source. It is followed by the Italian Sub and Spicy Cajun Chicken Sub in that source’s ranking.
The Hook & Ladder combines turkey breast and ham with Monterey Jack cheese, along with the toppings and condiments that come with the sandwich.
Firehouse Subs is also known for steaming its meats and cheeses before they are added to the sandwich. That preparation method helps produce the warm, moist texture associated with its hot subs.
The ranking can vary by source and time. Firehouse Subs does not publish an official lifetime sales ranking. So, the Hook & Ladder is not confirmed as the all-time best-selling sandwich.
