Spicy Chicken Sandwich Homemade Sauce

Featured in: Quick Crunch Fix

Master the art of a homemade spicy chicken sandwich. Start with chicken marinated in buttermilk and spices for tender flavor, then double-dredge for an ultra-crispy fried exterior.

Whip up a cooling, creamy sauce using mayo, sour cream, and a touch of hot sauce and lemon to perfectly balance the chicken's heat. Assemble this delight on a toasted brioche bun with fresh toppings for a crave-worthy, crunchy, and juicy experience.

The first time I attempted spicy chicken sandwiches at home, I severely underestimated the oil splatter situation. My kitchen looked like a crime scene, but that first bite—shatteringly crisp crust, juicy meat inside, cooling sauce hitting the heat—made every paper towel worth it. Now I keep extra aprons on hand and accept that great fried chicken demands a little chaos. My family starts asking for these as soon as the weather turns even slightly cool.

Last summer I made these for a crowd of skeptical friends who claimed nothing beats the famous chains. Silence fell over the patio after that first crunch—one person actually asked if I'd secretly ordered delivery. Now they're my go-to for feeding hungry groups, whether we're watching football or just celebrating Friday. The sauce recipe alone has been copied onto at least a dozen phone notes.

Ingredients

  • Chicken & Marinade: Buttermilk tenderizes the meat while hot sauce and spices build layers of flavor deep inside
  • All-purpose flour and cornstarch: This combination creates the crispest coating—cornstarch adds extra crunch flour alone cant achieve
  • Vegetable oil: You need enough depth to submerge the chicken without crowding the pan
  • Mayonnaise and sour cream: The duo creates a sauce thats tangy and rich without being overwhelmingly heavy
  • Brioche buns: Their slight sweetness and buttery texture stand up to bold flavors without getting soggy

Marinate the Chicken:
Whisk buttermilk with hot sauce and spices until fully blended, then submerge chicken pieces and refrigerate for at least one hour. This step is worth every minute of waiting.
Prepare the Dredge:
Mix flour, cornstarch, and all seasonings in a shallow dish until evenly distributed. Press chicken firmly into the mixture for the best adhesion.
Heat Your Oil:
Bring oil to 350°F and set up a wire rack over a baking sheet for draining. Proper temperature prevents greasy, soggy coating.
Dredge and Fry:
Coat marinated chicken in the flour mixture, pressing firmly and optionally repeating for extra crunch. Fry 4–6 minutes per side until deep golden and cooked through.
Make the Sauce:
Whisk together mayonnaise, sour cream, hot sauce, lemon juice, and spices until smooth. Let it sit for 10 minutes to meld flavors.
Assemble and Serve:
Toast buns lightly, spread sauce generously, then stack with chicken, pickles, lettuce, and tomato. Serve immediately while the crust is at its peak.

My younger brother used to insist on picking off every pickle slice until he tried one sandwich with them left on. Now he demands extra pickles on his portion and acts like he discovered the combination himself. Watching people customize these to their perfect bite has become part of the fun.

Mastering the Marinade

Overnight marinating makes a noticeable difference in tenderness and flavor penetration. I've learned to set up the marinade before bed so dinner practically cooks itself the next day. The chicken becomes impossibly juicy, with spice woven throughout rather than just clinging to the surface.

Temperature Control Secrets

An instant-read thermometer eliminated my worst fried chicken failures. Oil that's too cool absorbs grease, while too hot burns coating before meat cooks through. I aim for 350°F and let the oil recover between batches—patience yields better results than rushing.

Make-Ahead Magic

The sauce develops beautifully in the refrigerator and actually tastes better after a day. I often double the batch and keep it ready for quick sandwiches, fries, or drizzling over roasted vegetables. The dredge mixture can be pre-mixed and stored in an airtight container for weeks.

  • Freeze uncooked dredged chicken pieces between parchment paper for up to a month
  • Reheat leftover fried chicken at 375°F for 10 minutes to restore crispiness
  • Toast buns in the oven while chicken rests for optimal temperature alignment

There's something deeply satisfying about making restaurant-quality food in your own kitchen, especially when it involves crispy fried chicken and custom sauce. Hope these bring some crunch and joy to your table.

Recipe Questions & Answers

How can I ensure my chicken is extra crispy?

For maximum crispiness, after marinating, coat the chicken thoroughly in the dredge mixture, pressing firmly to adhere. For an even crunchier texture, perform a double-dredge by dipping the chicken back into the buttermilk mixture and then into the dredge again before frying.

What are good ways to adjust the spice level?

To increase the heat, simply add more cayenne pepper to both the chicken marinade and the dredge mixture. You can also boost the hot sauce content in both the marinade and the creamy topping for an extra kick. For less spice, reduce or omit the cayenne.

Can I prepare the sauce ahead of time?

Absolutely! The creamy homemade sauce can be prepared up to 2-3 days in advance. Store it in an airtight container in the refrigerator. A quick stir before serving will bring it back to its perfect consistency.

Are there alternatives if I don't want to deep fry the chicken?

While deep frying yields the crispiest result, you can try air frying or baking for a lighter option. For air frying, lightly spray the dredged chicken with oil and cook at 375°F (190°C) for 15-20 minutes, flipping halfway. For baking, bake at 400°F (200°C) until cooked through and golden.

What if I don't have brioche buns available?

While brioche buns add a delightful richness, you can certainly use other sturdy buns like potato buns, classic hamburger buns, or even a toasted ciabatta roll. Choose a bun that can hold up to the juicy chicken and generous sauce.

Can I use chicken thighs instead of breasts?

Yes, absolutely! Chicken thighs are an excellent alternative and often result in a juicier finished product due to their higher fat content. Just ensure they are pounded to an even thickness for consistent cooking and adjust cooking time if needed.

How to make it

Step 01

Prepare the Marinade: Whisk together buttermilk, hot sauce, salt, paprika, cayenne, garlic powder, and onion powder in a large bowl. Add chicken breasts, turning to coat completely. Cover and refrigerate for at least 1 hour, or overnight for maximum flavor penetration.

Step 02

Mix the Dredge: Combine flour, cornstarch, paprika, garlic powder, onion powder, salt, cayenne, and black pepper in a shallow dish. Mix thoroughly to distribute spices evenly throughout the coating mixture.

Step 03

Heat the Frying Oil: Pour vegetable oil into a heavy skillet or Dutch oven. Heat to 350°F. Place a wire rack over a baking sheet lined with paper towels for draining cooked chicken.

Step 04

Coat the Chicken: Remove chicken from marinade, allowing excess liquid to drip off. Press each piece firmly into the dredge mixture, coating completely. For extra crunch, repeat the dredging process to create a double layer.

Step 05

Fry the Chicken: Carefully place coated chicken into the hot oil. Fry for 4 to 6 minutes per side until deep golden brown and crispy. Verify internal temperature reaches 165°F. Transfer to wire rack to drain excess oil.

Step 06

Prepare the Sauce: Whisk mayonnaise, sour cream, hot sauce, lemon juice, smoked paprika, garlic powder, and honey in a small bowl until smooth and fully combined. Season with salt and pepper to taste.

Step 07

Toast the Buns: Lightly toast brioche buns in a skillet or toaster until golden and warm.

Step 08

Assemble the Sandwiches: Spread a generous layer of sauce on both cut sides of each bun. Place fried chicken on the bottom bun. Top with pickle slices, lettuce, and tomato if using. Crown with the top bun and press gently.

Step 09

Serve: Serve immediately while chicken remains crispy. Offer additional sauce on the side for dipping.
