The Firehouse Subs secret menu features popular off-menu items made by fans, such as the Brisket Hat Trick, which includes brisket, turkey, and ham topped with BBQ slaw, and the BBQ Bacon Cheddar Meatball.
These items are not listed on the regular menu, but you can still order them in 2026 by asking for specific ingredient changes or simple “hacks,” like adding marinara sauce to a chicken sub to make a Chicken Parmesan–style sandwich. Since these are custom orders, it’s best to explain the ingredients clearly and place your order during slower times so staff can prepare it just the way you want.
