Firehouse Subs Grilled Chicken Breast Sub (Copycat Recipe)
Ingredients
For the Grilled Chicken:
- 2 boneless, skinless chicken breasts
- 1 tbsp olive oil
- 1 tsp garlic powder
- 1 tsp paprika
- ½ tsp salt
- ¼ tsp black pepper
For the Sandwich:
- 1 sub roll (French bread or hoagie roll works too)
- 2 slices provolone cheese
- Mayonnaise (to taste)
- Deli mustard (to taste)
- Shredded iceberg lettuce
- Sliced tomato
- Thinly sliced white or red onion
- Pickle spears (for serving on the side)
Instructions
- Prep the Chicken
- Place each chicken breast between two sheets of plastic wrap or in a plastic bag.
- Gently pound with a meat mallet or rolling pin until about ¾-inch thick for even cooking.
- Season the Chicken
- In a small bowl, mix garlic powder, paprika, salt, and black pepper.
- Rub olive oil over both sides of the chicken.
- Sprinkle seasoning evenly on both sides.
- Grill the Chicken
- Preheat grill or grill pan to medium-high heat.
- Cook chicken for 4–7 minutes per side, until the internal temperature reaches 165°F (74°C).
- In the last minute, place provolone slices on top of the chicken to melt slightly.
- Toast the Roll
- Slice the sub roll lengthwise and lightly toast it on the grill or in a toaster until golden.
- Assemble the Sub
- Spread mayonnaise and deli mustard on both cut sides of the toasted roll.
- On the bottom half, layer shredded lettuce, sliced tomato, and onion.
- Place the cheesy grilled chicken breast on top.
- Close with the top half of the roll.
- Serve
- Slice the sub in half.
- Serve immediately with a crisp pickle spear on the side.
✨ Tips for Perfection:
- Marinate the chicken in olive oil, garlic powder, and paprika for 30 minutes before grilling for extra flavor.
- Use freshly baked sub rolls for that true Firehouse Subs taste.
- If you like a smoky flavor, add a pinch of smoked paprika to the seasoning mix.
