What to Eat at Firehouse Subs: Healthy Menu Choices and Nutrition Facts

Firehouse Subs

Verywell / Christian Alzate

One of the popular subway sandwich franchises, you can find Firehouse Subs all over the U.S., Puerto Rico, and Canada. This fast, casual chain allows patrons to either choose their own sandwich toppings, protein, and bread type, or order a specialty subway sandwich with preplanned toppings. Certain locations also offer salads, wraps, and soups, and you can decide to pair your main meal with sides, such as potato chips or macaroni and cheese.

Firehouse Subs offers certain menu items with healthy, low-calorie foods from which to choose, and you can maintain complete control over your order—allowing this restaurant to please a number of discerning palates and diets. But you shouldn't eat here too often to keep your sodium intake down.

What Experts Say

Firehouse Subs is all about comfort foods, with offerings like specialty subs and macaroni and cheese. Unless you are eating a salad here (which still contains too much sodium), you want to make this an infrequent stop. Or become more conscious of your choices by reducing your portion sizes and sticking to lean proteins like grilled chicken and roast turkey or the veggie sub.

Most Nutritious Option

Unlike a number of fast casual restaurants, you can find a number of healthy options on the Firehouse Subs menu, and the engineer hot specialty sub on small wheat is the most nutritious option based on its nutritional profile.

You can order a hot specialty subway sandwich with predetermined toppings. These include sandwiches such as a meatball with hot marinara sauce, the Smokehouse Beef and Cheddar Brisket, and Italian with Italian seasonings and meats.

✓ Engineer – Small Wheat

The small Engineer sandwich on wheat contains 350 calories, 18g fat, 4g saturated fat, 30g carbohydrates, 19g protein, and 1,150mg sodium. This has the healthiest protein on the menu (the turkey breast), as well as sautéed mushrooms and vegetables. If you ask for no Swiss cheese, you can cut the fat by 8g.

✗ Smokehouse Beef & Cheddar Brisket – Large White

The large smokehouse beef and cheddar brisket sandwich on white has 1,500 calories, 102g fat, 33g saturated fat, 97g carbohydrates, 55g protein, and 3,200mg sodium. This is almost the total calories you should eat in a day. If you are craving this sandwich, order the small and switch to wheat bread, or split it in two and save half for later.

Local Specials

Rather than build-your-own subs with toppings and proteins, you can order cold specialty sandwiches with preplanned add-ons.

✓ Virginia Ham – Small Wheat

The small Virginia honey ham on wheat with vegetables contains 380 calories, 19g fat, 4g saturated fat, 36g carbohydrates, 19g protein, and 1,150mg sodium. You can customize this order if you'd like, but the calorie count will increase with extra liquid condiments and cheese toppings.

✗ Jamaican Jerk Turkey - Large White

The large Jamaican jerk turkey on white has 1,140 calories, 55g fat, 13g saturated fat, 111g carbohydrates, 62g protein, and 3,080mg sodium. You should split this sandwich up into several servings rather than eat this all for one meal. Even switching the bread to wheat can lessen the sodium count by 300mg.

Build Your Own Sub

The Firehouse Subs menu is also entirely customizable and you can build your own sub with any of the available meat, cheese, vegetable, and topping options. For the carb-enthusiasts, building your own sandwich with loads of low-calorie vegetables on wheat bread (lower in sodium than white bread) is the healthiest sandwich.

To create the healthiest sandwich, you should consider ordering the following toppings on your sub:

  • Spicy mustard for the liquid condiment (0 calories)
  • Iceberg lettuce (15 calories)
  • Cherry pepper ring (10 calories)
  • Onions (20 calories)
  • Pickles (5 calories)
  • Tomatoes (15 calories)
  • Mushrooms (5 calories)

For additional toppings, the turkey breast contains 150 calories per serving and cheese slices range from 100 to 110 calories for a medium sandwich.

✗ Tuna Salad - Large White

Meanwhile, the tuna salad sandwich on large white bread delivers 1,540 calories, 97g fat, 18g saturated fat, 103g carbohydrates, 71g protein, and 3,030mg sodium. Drop down to a small tuna salad sandwich to save nearly 1,000 calories and 2,000mg sodium.

Food Allergies and Safety

For those with food allergies, Firehouse Subs provides menu items free of gluten, tree nuts, soy, and dairy. However, you should eat with caution as the establishment can have cross-contamination of foods. All sandwiches are prepared on the same counter, and preparers might not switch latex gloves, allowing allergens to carry between sandwich preparations.

To ensure your safety against allergens, the following can help:

  • Use the website. The Firehouse Subs has a valuable interactive allergen menu on their website. You simply select the allergens you wish to avoid out of 14 choices. The site then displays items you can safely eat.
  • Build your own sub and skip the specialty sub offerings. This way you have complete control over the toppings.
  • Ask questions of the staff. They can let you know the ingredients in the bread and wraps in case you have a wheat or nut allergy.
