How to Make The Best Spicy Chicken Sandwich Recipe
Step 1: Marinate for Maximum Flavor
Begin by combining buttermilk, Sriracha, salt, pepper, and garlic powder in a medium bowl. This marinade not only adds layers of spice and tang but also tenderizes the chicken thighs. Immerse the chicken thoroughly and refrigerate for at least 4 hours; overnight marinating yields the juiciest, most flavorful results.
Step 2: Prepare the Crispy Coating
Mix together the flour, cornstarch, paprika, salt, pepper, garlic powder, and cayenne powder in a large bowl. This seasoning blend creates that signature crunch and vibrant color you’ll love. Adding 2 tablespoons of the spicy marinade to the dry mix elevates the flavor intensity for the ultimate crust.
Step 3: Coat the Chicken Evenly
Dip each piece of marinated chicken into the flour mixture, making sure the coating clings generously and evenly. This step is key for building that addictive crisp outside while sealing in the juicy, tender interior.
Step 4: Fry to Golden Perfection
Heat your oil to 325˚F (165˚C) in a deep skillet—this temperature is perfect to cook the chicken through without burning the crust. Fry each piece for 3 to 4 minutes on each side until the chicken reaches an internal temperature of 165˚F (75˚C) and boasts a beautiful golden brown hue.
Step 5: Build Your Sandwich
While the chicken fries, mix the spicy mayo by combining mayonnaise and Sriracha. Spread this flavorful sauce generously on both halves of the toasted and buttered buns. Add your perfectly crispy chicken along with your chosen fresh toppings like lettuce, tomato, and pickles. Serve immediately and enjoy every spicy, crunchy bite!
How to Serve The Best Spicy Chicken Sandwich Recipe
Garnishes
The simplest garnishes like crisp lettuce, juicy tomato slices, and tangy pickles add just the right freshness and crunch to balance the sandwich’s heat and richness. Feel free to customize with sliced onions or even a drizzle of honey for a playful sweet contrast.
Side Dishes
This sandwich pairs incredibly with classic sides like crispy French fries or crunchy coleslaw to keep things fresh and satisfying. For a lighter twist, consider a crisp pickle spear or a refreshing cucumber salad to cut through the spice.
Creative Ways to Present
For a fun presentation, serve the sandwich with a stack of thick-cut sweet potato fries or alongside a zesty slaw served in a mason jar. Wrapping the sandwich in parchment paper adds a rustic, street-food vibe that amps up the overall experience.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, store the cooked chicken separately from the buns to prevent sogginess. Keep the chicken in an airtight container in the fridge for up to 3 days. This way, the chicken will retain a better texture for reheating.
Freezing
You can freeze the fried chicken pieces by wrapping them tightly in foil or plastic wrap, then placing them in a freezer-safe container for up to 2 months. Avoid freezing the buns or any mayo-based sauces to maintain freshness and quality.
Reheating
Reheat the fried chicken in an oven or air fryer set to 350ËšF (175ËšC) for about 10 minutes to help maintain its crispiness. Avoid microwaving, which tends to make the crust soggy. Toast the buns fresh before assembling the sandwich again.
FAQs
Can I use chicken breasts instead of thighs?
Absolutely! Chicken breasts will work, though thighs tend to stay juicier and more flavorful after frying. If you use breasts, pound them to an even thickness to ensure they cook evenly.
How spicy is the sandwich?
This sandwich has a noticeable kick thanks to the Sriracha and cayenne, but you can easily adjust the heat level by reducing the cayenne powder or choosing a milder hot sauce.
Do I have to marinate the chicken overnight?
While marinating overnight gives the best flavor and tenderness, 4 hours is sufficient if you’re short on time. The longer, the better!
What’s the best oil for frying?
Use a neutral oil with a high smoke point like vegetable, canola, or peanut oil. These oils allow for even frying and won’t overpower the spices in your chicken.
Can I make the spicy mayo ahead of time?
Yes! You can prepare the spicy mayo a day in advance and keep it refrigerated in an airtight container. This allows the flavors to meld and saves time when assembling the sandwich.

Ingredients
Chicken Marinade
- 4 pieces boneless skinless chicken thighs, pounded to even thickness
- 1 cup buttermilk
- 2 tbsp Sriracha (or your favorite hot sauce)
- 1 tsp salt
- 1 tsp pepper
- 1 tsp garlic powder
Flour Coating
- 1 cup all-purpose flour
- 3 tbsp cornstarch
- 1 tbsp paprika powder
- 1 tsp salt
- 1 tsp pepper
- 1 tsp garlic powder
- 1 tsp cayenne powder (reduce for less spice)
Spicy Mayo Sauce
- 1/2 cup mayonnaise
- 2 tbsp Sriracha (or your choice of hot sauce)
Other Ingredients
- Cooking oil (for frying)
- 4 burger buns, lightly toasted with butter
- Lettuce, tomato, and/or pickles, sliced (or your choice of toppings)
Instructions
- Marinate the Chicken: In a medium bowl, combine buttermilk, Sriracha, salt, pepper, and garlic powder. Add the pounded chicken thighs and ensure they are fully submerged. Cover and refrigerate for at least 4 hours or preferably overnight to tenderize and infuse flavor.
- Prepare the Flour Mixture: In a large bowl, whisk together all-purpose flour, cornstarch, paprika, salt, pepper, garlic powder, and cayenne powder until evenly combined. This mixture will give the chicken a crispy and spicy coating.
- Coat the Chicken and Make Sauce: Add 2 tablespoons of the marinade liquid to the flour mixture and stir with a fork to create a slightly moistened dredge. Dredge each piece of marinated chicken in the flour mixture, pressing gently to ensure an even, thorough coating. Separately, mix the mayonnaise and Sriracha in a small bowl to prepare the spicy mayo sauce.
- Fry the Chicken: Heat cooking oil in a deep skillet over medium heat until it reaches 325ËšF (165ËšC). Carefully place the coated chicken thighs in the hot oil and fry for about 3-4 minutes on each side, or until the crust is golden brown and an internal thermometer reads 165ËšF (75ËšC) at the thickest part.
- Assemble the Sandwich: Generously spread the spicy mayo sauce on the lightly toasted buns. Layer the fried chicken thighs on the bottom bun, followed by your choice of lettuce, tomato slices, and pickles. Top with the other bun half, serve immediately, and enjoy the perfect spicy chicken sandwich.
Notes
- For best results, marinate the chicken overnight to enhance tenderness and flavor.
- If you prefer less spice, reduce or omit cayenne powder and adjust Sriracha to taste.
- Use a thermometer to ensure the oil temperature remains steady for optimal frying.
- Leftover spicy mayo can be stored in the refrigerator for up to 3 days.
- Try swapping out burger buns for brioche or sandwich rolls for a different texture and flavor.
