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!

Making the Perfect KETO Salad at Firehouse Subs

If you are on the ketogenic diet, you know how hard it is to stay within your carb limit!

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)
  • Hook & Ladder Salad: 16g net carbs

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!

All it takes for a delicious keto-friendly salad is some cheese, meat, veggies, and savory toppings! Mix and match the following low-carb items as per your taste:

PS: The portion size of these toppings is based on a MEDIUM sub.

The Coleslaw served at Firehouse Subs is quite high in carbs (7g net carbs) because it contains carrots and a lot of mayo.

Now you are well prepared to make your own deliciously low-carb salad! Mix and match from the above ingredients to suit your taste buds.

PS: I highly recommend that you don’t cross the “10g carbs” mark with a salad. The foodie in you might justify the splurging, but you’d have exhausted your carb quota for the day!

My #1 KETO Order at Firehouse Subs

Firehouse Subs is undoubtedly my favorite keto restaurant. There are few such places that are so open to customizations and make your order right in front of you (I really appreciate the transparency!)

Whenever dining out on keto, I always strive for a balance between taste and macros (fats, carbs, and proteins). I look for options that will keep me full for at least the next few hours.

This is my staple keto salad at Firehouse Subs:

  • Provolone Cheese
  • USDA Choice Corned Beef Brisket
  • USDA Choice Pastrami
  • Italian Salad Dressing
  • Spicy Mustard

Nutrition: 500 calories | 25g fat | 6g net carbs | 0g fiber | 4g sugar | 61g protein

The portion size of toppings is the same as that of a large Speciality Sub. In essence, you can call it a “New York Steamer” large sub that is served in a bowl (without mayo!)


In a nutshell, eating keto at Firehouse Subs involves having your favorite subs served in a bowl! All you have to do is stay away from high-carb toppings and sugary sauces (like Sweet Baby Ray’s BBQ Sauce).

Luckily, the folks at Firehouse Subs are very open to customizations and you can literally combine anything and everything under the sun! They have a ton of low-carb meats, cheese, and toppings, which ensure enough variety in your meals.
