Behind the Heat: The Secret Ingredients in Firehouse Subs’ ‘Hot Ones’ Collaboration.

Firehouse Subs has officially turned up the heat with its ‘Hot Ones’ collaboration, bringing the fiery flavors of the viral interview series to its sandwich lineup.

At the heart of this spicy lineup is the Last Dab Dill Pickles, a Firehouse-exclusive twist on Hot Ones’ legendary Last Dab hot sauce.

Traditionally, the Last Dab is made with Pepper X, a chili that surpasses even the Carolina Reaper in heat. For Firehouse Subs, this blistering sauce has been infused into pickles, adding a tangy yet scorching kick to every bite.

A Sauce Lineup That Builds the Burn Firehouse Subs isn’t just relying on one sauce. The ‘Hot Ones’ sandwiches feature a layered heat experience:

Classic Hot Ones Sauce – A balanced mix of smoky, tangy, and spicy notes to start the heat. Los Calientes Rojo – A mid-level spice with a blend of applewood smoked red jalapeños and citrus.

To complement the heat, Firehouse Subs has perfectly paired these sauces with their signature meats, such as slow-smoked turkey or grilled chicken, ensuring a spicy yet flavorful experience rather than just pure burn.

With this Hot Ones collab, Firehouse Subs is proving that spice lovers don’t have to settle for bland sandwiches. This lineup brings authentic, layered heat—but only the boldest should dare to take the first bite!

Spicy food challenges can be entertaining, but they shouldn’t be taken lightly. Know your limits, stay hydrated, and never push past the point of real pain. After all, there’s a fine line between fun and fiery regret.
