Firehouse Subs Menu: An OVERVIEW

Firehouse Subs is a casual fast-food restaurant serving fresh subway sandwiches since 1994! You can spot them in various strip malls and shopping centers across the U.S. and neighboring areas.

Their concept is quite similar to Subway, but you’ll find a lot more options at Firehouse Subs! You can either choose your own breading, meat, and toppings or simply order their “Speciality Subs” with fixed ingredients.

The sole reason behind their success is the super quick fast food which is also light on your pockets! And if you choose the right toppings, you can order for pretty much any diet: Paleo, Keto, Vegan, Carnivore, etc.

Firehouse Subs offers 3 sizes of Sub:

Small Subs: 4 inches long
Medium Subs: 8 inches long
Large Subs: 12 inches.

Keep in mind that you must adjust the nutritional values based on the size you order. I’ve seen a lot of people mess this up! Their official document clearly lays out the nutritional data for each portion size.

The Hot Speciality subs contain classic combinations of meat, sauces, and toppings that enjoy huge popularity among its fans.

Apart from the subway sandwiches, Firehouse Subs is also famous for its freshly chopped salads. The Hook & Ladder salad always gets me drooling! (You have to toss out the ham to make it truly keto-friendly.)

Let’s talk beverages. I must say they have a humungous range of beverages to choose from! At Firehouse Subs, you can find every Coca-Cola drink present on Earth! Plus, they also have their exclusive Cherry-Lime Aid and their freshly-brewed iced tea. The law of keto says we can have anything as long as it’s sugar-free.

Tip: Always carry a pack of liquid stevia or any other sweetener to light up your sugar-free drinks at restaurants!

Having a salad is a no-brainer on any kind of weight-loss diet. And it becomes all the more important on keto. It’s an easy way to consume your much-needed fats and minimize your carb intake (no bread, lots of meat!)

Firehouse Subs offer three salads be default in their menu:

Italian Salad with Grilled Chicken: 9g net carbs
Firehouse Salad: 9-22g net carbs (depending on your choice of meat)

You can further lower the carb count with a few changes in the toppings. In fact, they give you full freedom to choose your own toppings and build your customized salads!

This saves you a ton of time and the pain of removing unwanted, high-carb items manually (such as tomatoes). Plus, it also avoids food wastage!
