Firehouse Subs Nutrition Menu 2026
The Firehouse Subs nutrition menu for 2026 — real per-size calorie counts across every category, the lightest and highest-calorie picks, protein and sodium data for the Medium subs, and allergen guidance, all matched to the same three-city menu research behind our full price guide.
Calories on the Firehouse Subs Nutrition Menu for 2026 range from 60 Cal (a Side Salad) up to 1,920 Cal for a Large Pepperoni Pizza Meatball Sub, based on Firehouse Subs’ own official Nutritionix data matched to our three-city menu research as of 19 Sep 2026. A Medium hot sub typically runs 690–1,250 Cal, and most Medium subs carry 35–52g of protein — see the Protein & Sodium Snapshot below.
Firehouse Subs doesn’t publish a standalone allergen menu on its own site; its nutrition data runs through Nutritionix instead — see the Allergen Guidance section for what that means for you. For exact prices alongside these calories, see our complete Firehouse Subs Menu Prices guide.
Calorie Range by Category
These Firehouse Subs Nutrition Menu calorie counts are the same official per-size figures already used in our Firehouse Subs Menu Prices guide, grouped by category here so you can compare ranges at a glance. Catering rows are shown separately since those are whole-platter totals meant to feed a group, not a single serving.

|---|---|---|
| Hot & Specialty Subs (S/M/L) | 350–1,920 Cal | 18 |

Protein & Sodium Snapshot (Medium Subs)
Beyond calories, Firehouse Subs’ own Nutritionix data also breaks out protein, sodium and carbs per sub. Here’s that data for every Medium hot and specialty sub we could match by exact item name to Firehouse’s official export — useful if you’re watching sodium or looking for a higher-protein pick.

Two items don’t appear above by design, not oversight: Firehouse Meatball and Smokin’ Honey Steak Melt aren’t captured in our matched Nutritionix macro data for protein and sodium (their calorie figures on the price guide come from a broader Firehouse Subs source). The Build Your Own cold subs Grilled Chicken Breast, Honey Ham and Smoked Turkey & Provolone also aren’t in this protein/sodium table — Firehouse’s Nutritionix export doesn’t list those as standalone sandwich entries the way it does for Corned Beef, Pastrami, Roast Beef, Tuna Salad and Veggie. We’re disclosing that gap rather than estimating a number.
Allergen Guidance
Rounding out this Firehouse Subs Nutrition Menu guide, Firehouse Subs doesn’t publish its own standalone allergen menu the way some chains do. Its official calorie and macro data — the same data behind this guide — runs through Nutritionix, a third-party nutrition database Firehouse licenses to publish its figures, rather than a dedicated allergen page on firehousesubs.com itself.
Our own three-city research captured prices and calories, not item-by-item allergen tags, so this guide does not publish an invented per-item allergen table. Sub rolls, garlic bread and several sides contain wheat/gluten by nature of their ingredients, and toppings, cheeses, sauces and hot sauces vary sub to sub and location to location.
If you’re managing a food allergy or a gluten-related condition, confirm current allergen details directly with the restaurant before ordering, and check Firehouse Subs’ published nutrition data at firehousesubs.com rather than relying on this guide alone.

Does Firehouse Subs publish allergen information?
Firehouse Subs’ nutrition and calorie data is published through Nutritionix rather than a standalone allergen menu on firehousesubs.com. Our own three-store research captured calories and macros, not item-by-item allergen tags, so confirm specific allergens directly with the restaurant or through Firehouse’s official nutrition data before ordering.

Medium hot and specialty subs in our research run from about 690 calories (Engineer) up to 1,250 (Pepperoni Pizza Meatball Sub), with most falling in the 700-950 range.
Our Methodology
Calorie figures in this Firehouse Subs Nutrition Menu guide come from Firehouse Subs’ own official Nutritionix nutrition export, matched to items captured from each restaurant’s live official online-ordering menu on 9-11 Sep 2026, the same three-city dataset (Atlanta, Dallas, New York) used across this cluster.
The category calorie-range table and the lightest/highest item picks above are drawn directly from that same dataset, not estimated. Catering whole-platter totals are shown separately since they feed a group rather than one person.
Protein and sodium figures in the snapshot table above were matched to Firehouse’s Nutritionix export by exact item name; where no exact match existed (Firehouse Meatball, Smokin’ Honey Steak Melt, and the Grilled Chicken Breast, Honey Ham and Smoked Turkey & Provolone cold subs), we disclosed the gap rather than estimating a number.
No item-level allergen data was captured in our own three-city research. Firehouse Subs does not publish a standalone allergen page on firehousesubs.com; its nutrition data runs through Nutritionix instead. Confirm allergen specifics with the restaurant directly before ordering.
