Firehouse Subs Roast Beef Sub (Copycat Recipe)

Firehouse Subs is known for steaming their meats and cheese, not just stacking cold cuts. This creates a warm, melty core layered over crisp, fresh toppings — the hallmark of their “Fully Involved” subs. With this recipe, you can recreate their USDA Choice Roast Beef Sub at home.

Ingredients

For the Sub

• 1 sub roll or hoagie roll
• 4–6 oz thinly sliced deli roast beef (high-quality)
• 2 slices provolone cheese

“Fully Involved” Toppings

• Mayonnaise (to taste)
• Deli mustard (to taste)
• Shredded iceberg lettuce
• Sliced tomato
• Thinly sliced white or red onion

For Serving

• 1 kosher dill pickle spear

Instructions

1. Prepare the Bread

• Slice the sub roll in half lengthwise.
• Lightly toast if desired, but for authenticity, keep it soft or just warm slightly in the oven.

2. Steam the Meat & Cheese

Stovetop Method

1. Bring 1/4 cup water to a boil in a pot with a steamer basket.
2. Place roast beef slices on parchment, top with provolone.
3. Steam 1–2 minutes until the cheese melts and meat is hot.

Microwave Method

1. Place roast beef and cheese on a microwave-safe plate.
2. Cover with a damp paper towel.
3. Microwave 30–60 seconds, until cheese is melted and meat is warm.

3. Assemble the Sub

1. Spread mayonnaise on one side of the roll and deli mustard on the other.
2. On the bottom half, layer lettuce, tomato, and onion.
3. Add the hot roast beef and melted provolone over the fresh vegetables.
4. Close with the top half of the roll.

4. Serve

• Slice in half and serve immediately with a dill pickle spear on the side.
