Firehouse Subs keeps no printed secret menu at any of its counters. Regulars build off-menu combinations instead, all starting from a sub already on the board. Brisket Hat Trick and Italian Inferno are two of the better-known requests.
None of the twelve items carries its own price, since each one is a modified order rather than a separate recipe. Naming the real sandwich and the swap gets an order built right the first time.
The short answer
The Firehouse Subs secret menu covers twelve off-menu builds, each one modifying a sub already on the printed board. Brisket Hat Trick layers a second meat onto the Smokehouse Beef & Cheddar Brisket, and Italian Inferno loads extra pepperoni onto the Italian. None of the twelve carries a price of its own.

Firehouse Subs Secret Menu Items
The Firehouse Subs secret menu runs to twelve off-menu builds, each one showing up often enough across ordering guides to track by name. Every build starts from a sub already on the printed board. A swapped protein, an added topping or a Hot Sauce Bar bottle is usually all it takes.
Meatball & Brisket Remixes at Firehouse Subs
Chicken Parm Sub, BBQ Bacon Cheddar Meatball, Brisket Bacon Melt and Brisket Hat Trick all rework a meatball or brisket sub already on the board. Each one swaps a protein or piles on bacon rather than adding anything new to the kitchen. Brisket Hat Trick goes furthest, stacking a second meat onto the Smokehouse Beef & Cheddar Brisket base.
| Item | How to Order |
|---|---|
| Chicken Parm Sub | Order a Meatball sub built with grilled chicken instead of meatballs, then add marinara, melted provolone, Italian seasoning and red pepper flakes or hot sauce. |
| BBQ Bacon Cheddar Meatball | Ask for a Meatball sub with cheddar and bacon added, finished with BBQ sauce and hot sauce on request. |
| Brisket Bacon Melt | Request a Smokehouse Beef & Cheddar Brisket with bacon added, plus jalapenos or a Hot Sauce Bar bottle for extra heat. |
| Brisket Hat Trick | Start with a Smokehouse Beef & Cheddar Brisket, add bacon, then layer in pastrami, corned beef or extra cheese if the store can build it. |
Named Sub Rebuilds at Firehouse Subs
Hook & Ladder Club, Firehouse Hero Fully Overloaded, New York Steamer Rebuild and Italian Inferno all rebuild a named sub with extra layers. Bacon, extra cheese and extra pickles turn up across all four requests. Firehouse Subs kitchens treat these as modified orders, not separate recipes.
| Item | How to Order |
|---|---|
| Hook & Ladder Club | Ask for a Hook & Ladder with bacon added, or request extra turkey and a cheese swap to build it out further. |
| Firehouse Hero, Fully Overloaded | Order a Firehouse Hero with bacon and extra provolone added, then finish with hot sauce or extra pickles. |
| New York Steamer Rebuild | Request a New York Steamer with extra mustard and extra pickles, then add a Hot Sauce Bar bottle like TABASCO Green Jalapeno, Cholula or Backdraft Fire Sauce. |
| Italian Inferno | Ask for an Italian with extra pepperoni added, plus banana peppers or jalapenos and a bottle from the Hot Sauce Bar. |
Hot Sauce Bar Hacks at Firehouse Subs
Captain Sorensen’s Sweet Heat Sub and Turkey Bacon Ranch But Make It Actually Interesting both draw from the same nine-bottle Hot Sauce Bar lineup.

Firehouse Subs keeps those bottles stocked at the counter of most locations.
| Item | How to Order |
|---|---|
| Captain Sorensen’s Sweet Heat Sub | Pick a Hook & Ladder, Turkey Bacon Ranch, Italian, Chicken ‘N’ Cheddar Rancher or Steak & Cheese Melt, then add Captain Sorensen’s Datil Pepper Hot Sauce or Bee Sting Honey n’ Habanero. |
| Turkey Bacon Ranch, But Make It Actually Interesting | Order a Turkey Bacon Ranch with pepper jack swapped in for the cheddar, then add jalapenos and a mild or medium Hot Sauce Bar bottle. |
| Chicken ‘N’ Cheddar Rancher Hot Sauce Hack | Ask for a Chicken ‘N’ Cheddar Rancher finished with Captain Sorensen’s, Frank’s RedHot, TABASCO Green Jalapeno or Bee Sting Honey n’ Habanero. |
| Steak & Cheese Melt With Heat | Request a Steak & Cheese Melt with hot sauce added, plus jalapenos or extra onions and peppers if wanted. |
