What Is a Spicy Crispy Chicken Sub?

A spicy crispy chicken sub is a hearty submarine sandwich starring breaded and fried chicken that's marinated in spicy buttermilk for tenderness and heat. It's assembled on a long sub roll (or hoagie) with crisp lettuce, juicy tomatoes, tangy pickles, and a creamy spicy mayo or buffalo sauce for extra zing. Unlike milder chicken subs, this version packs a punch with cayenne, paprika, and hot sauce in the breading and marinade. Often compared to fast-food hits, it's a no-fuss homemade alternative that's fried or air-fried for that golden crunch. Great for meal prep or parties, it's customizable for heat levels and naturally gluten-free adaptable with the right buns.

Ingredients for Spicy Crispy Chicken Sub

This recipe serves 4 subs and uses simple pantry staples for an authentic spicy kick.

For the Chicken:

• 4 boneless, skinless chicken breasts (or thighs for juicier results)
• 1 cup buttermilk
• 2-3 tbsp hot sauce (like Sriracha or Frank's)
• 1 tsp paprika
• 1 tsp garlic powder
• 1 tsp salt
• 1/2 tsp black pepper

For the Breading:

• 1 cup all-purpose flour
• 1/4 cup cornstarch (for extra crispiness)
• 1 tsp cayenne pepper (adjust for spice level)
• 1 tsp paprika
• 1 tsp garlic powder
• 1 tsp salt
• 1/2 tsp black pepper

For Frying and Assembly:

• Vegetable oil for frying (about 2 cups)

• Tomato slices
• Pickle slices
• Optional: Cheese slices or coleslaw for added crunch

Step-by-Step Instructions: How to Make Spicy Crispy Chicken Sub

This straightforward method yields perfectly crispy chicken every time. Prep time: 15 minutes | Marinate: 30 minutes (optional) | Cook time: 15 minutes.

1. Marinate the Chicken: In a bowl, whisk buttermilk, hot sauce, paprika, garlic powder, salt, and pepper. Add chicken breasts, ensuring they're fully coated. Marinate in the fridge for at least 30 minutes (or up to 4 hours for deeper flavor).
2. Prepare the Breading: In a shallow dish, mix flour, cornstarch, cayenne, paprika, garlic powder, salt, and pepper.
3. Bread the Chicken: Remove chicken from marinade, letting excess drip off. Dredge each piece in the flour mixture, pressing to adhere. For extra crunch, double-dip: back into marinade, then flour again.
4. Fry the Chicken: Heat oil in a deep skillet or Dutch oven to 350°F (175°C). Fry chicken in batches for 5-7 minutes per side until golden and internal temperature reaches 165°F. Drain on paper towels.
5. Assemble the Subs: Slice sub rolls lengthwise and toast lightly. Spread spicy mayo on both sides. Layer with lettuce, fried chicken, tomato, pickles, and any extras. Close and slice in half if desired.

The Ultimate Spicy Fried Chicken Sandwich Recipe

For an air-fryer version, spray breaded chicken with oil and cook at 400°F for 12-15 minutes, flipping halfway.

Tips for the Perfect Spicy Crispy Chicken Sub

• Spice Control: Start with less cayenne and adjust—taste the breading mix before coating.
• Crispy Secret: Cornstarch in the breading ensures shatteringly crisp results without sogginess.
• Oil Temp: Use a thermometer to maintain 350°F; too low makes it greasy, too high burns the outside.
• Make-Ahead: Marinate chicken overnight; fry just before serving for best texture.
• Healthier Twist: Bake at 425°F for 20 minutes or air-fry to cut down on oil.
• Avoid Mistakes: Don't overcrowd the fryer—cook in batches for even browning.

Variations on Spicy Crispy Chicken Sub

Customize for endless excitement:

• Buffalo Style: Toss fried chicken in buffalo sauce and top with blue cheese slaw.
• Honey-Sriracha: Drizzle with honey-hot sauce glaze for sweet-heat balance.
• Vegan Option: Swap chicken for cauliflower florets or tofu.
• Cheesy Upgrade: Add melted pepper jack or cheddar.
• Asian Fusion: Use gochujang in the marinade for Korean-inspired spice.
• Low-Carb: Serve on lettuce wraps instead of rolls.

These tweaks suit diets or occasions like tailgates.
