Crispy Chicken Sandwich Recipe

There are some meals that just hit the spot, and for me, a truly magnificent crispy chicken sandwich is right at the top of that list. I’m not talking about a limp, sad fillet in a soggy bun. I mean a sandwich with a shattering, craggy crust that gives way to incredibly juicy, flavourful chicken, all tucked into a soft, toasted brioche bun with a tangy sauce and crisp pickles. It’s the kind of lunch that makes a weekend feel special.
Crafting the ultimate fried chicken sandwich has been a bit of a mission in my kitchen. It took quite a bit of tinkering with marinades, flour blends, and frying techniques to land on this version. After testing this recipe five times, I finally got it just right. The secret lies in a buttermilk brine that tenderises the chicken beautifully, and a double dredge in seasoned flour which guarantees that coveted crunchy coating. It’s a bit more involved than just popping something in the oven, but the results are absolutely worth the effort.
This is the kind of recipe that works beautifully for a relaxed Saturday lunch, a fun dinner, or whenever you feel like treating yourself to something truly satisfying. It’s a hands-on cook that always gets compliments, turning a simple chicken sandwich into a memorable meal.
Recipe Overview
This crispy chicken sandwich recipe focuses on creating two key textures: an incredibly crunchy, well-seasoned crust and a supremely tender, juicy chicken thigh interior. The buttermilk brine is non-negotiable; it works its magic to ensure the chicken doesn’t dry out during frying. The flavour profile is savoury with a hint of warmth from smoked paprika and a gentle kick of cayenne, balanced by a creamy, tangy sauce. I found that using chicken thighs instead of breast meat makes a world of difference in the final taste and texture.

Why You’ll Love This Crispy Chicken Sandwich Recipe

Ingredients You’ll Need
For this recipe, we’re using simple, readily available ingredients. The key is using chicken thighs, as their higher fat content keeps them moist and flavourful during frying. When it comes to mayonnaise for the sauce, I always reach for Hellmann’s Real Mayonnaise; its creaminess and balanced flavour provide the perfect base.
- For the Chicken:
- 4 boneless, skinless chicken thighs (approx. 600g)
- 300ml buttermilk
- 1 tbsp dill pickle juice (from the jar)
- 1 tsp fine sea salt
- 1 litre vegetable or sunflower oil, for frying
- For the Flour Dredge:
- 250g plain flour
- 2 tbsp cornflour
- 2 tsp smoked paprika
- 2 tsp garlic powder
- 1 tsp onion powder
- 1 tsp black pepper, freshly ground
- 1 tsp fine sea salt
- ½ tsp cayenne pepper (or more, to taste)
- For Assembly:
- 4 brioche buns
- Butter, for toasting
- 100g mayonnaise
- 1 tbsp sriracha or other chilli sauce (optional)
- Dill pickles, sliced
- Iceberg lettuce, shredded
Sophia’s Tip: Don’t be tempted to skip the pickle juice in the brine! It seems like a minor addition, but its acidity works with the buttermilk to tenderise the chicken and adds a subtle background tang that really elevates the final sandwich.
How to Make This Crispy Chicken Sandwich Recipe
The process is straightforward. We’ll start by brining the chicken, then prepare the seasoned flour, and finally, fry the chicken to golden perfection before assembling our delicious sandwiches.
- Brine the Chicken: In a medium bowl, whisk together the buttermilk, pickle juice, and 1 tsp of salt. Add the chicken thighs, ensuring they are fully submerged. Cover the bowl and refrigerate for at least 4 hours, or preferably overnight for the most tender results.
- Prepare the Dredge: In a separate shallow dish or large bowl, combine the plain flour, cornflour, smoked paprika, garlic powder, onion powder, black pepper, remaining salt, and cayenne pepper. Whisk until everything is evenly distributed.
- Set Up Your Station: Remove the chicken from the fridge about 20 minutes before you plan to fry. Place the bowl of brined chicken, the dish of seasoned flour, and a clean plate or wire rack next to your hob. This makes the dredging process much tidier.
- Dredge the Chicken: Take one chicken thigh from the buttermilk, letting any excess drip off. Place it in the seasoned flour and toss to coat completely. Now, dip it *back* into the buttermilk for a second, and then return it to the flour for a final, generous coating. I find that pressing the flour firmly into the chicken on this second dredge is the real secret to those craggy, ultra-crispy bits we all love. Place the coated chicken on your clean plate and repeat with the remaining thighs.
- Heat the Oil: Pour the oil into a large, heavy-bottomed pan or Dutch oven until it’s about 4-5 cm deep. Heat over a medium-high heat until it reaches 175°C (350°F) on a cooking thermometer. Getting the temperature right is crucial for a non-greasy finish. For guidance on cooking chicken safely, the Food Standards Agency has helpful advice.
- Fry the Chicken: Carefully place two chicken thighs into the hot oil, making sure not to overcrowd the pan. Fry for 4-6 minutes on each side, until deep golden brown and the internal temperature reaches 75°C (165°F).
- Rest the Chicken: Once cooked, remove the chicken from the oil using tongs and place it on a wire rack to drain. This allows air to circulate, keeping the underside crispy. Let it rest for a few minutes while you fry the remaining chicken.
- Prepare the Buns and Sauce: While the chicken is resting, split your brioche buns and lightly butter the cut sides. Toast them in a dry pan until golden. In a small bowl, mix the mayonnaise with the sriracha, if using.
- Assemble Your Sandwich: Spread the spicy mayo on both halves of the toasted buns. Place a piece of crispy chicken on the bottom bun, top with sliced pickles and a generous handful of shredded lettuce, and finish with the top bun. Serve immediately.
Tips From My Kitchen
- Temperature Control is Key: An oil thermometer is your best friend here. If the oil is too cool, the chicken will absorb it and become greasy. If it’s too hot, the crust will burn before the chicken is cooked through. Maintain the oil at a steady 175°C.
- The Secret Step for Crunch: Don’t skip the double dredge (flour -> buttermilk -> flour). I learned that adding a tablespoon of the wet buttermilk brine into your dry flour mixture and mixing it with your fingertips creates little clumps that stick to the chicken, resulting in an even craggier, crispier texture.
- Make-Ahead Advice: The chicken can be left to marinate in the buttermilk for up to 24 hours, which is great for prep. You can also mix the seasoned flour and store it in an airtight container for weeks. The frying, however, is best done just before serving.
- Storage: Leftover fried chicken can be stored in an airtight container in the refrigerator for up to 2 days. To reheat and revive the crispiness, place it in an oven or air fryer at 190°C (170°C fan) for 10-15 minutes until hot and crispy again.
Equipment You’ll Need
- Large heavy-bottomed pan or Dutch oven (for frying)
- Cooking thermometer
- Tongs
- Wire rack
- Mixing bowls and shallow dishes
Common Mistakes to Avoid
- Overcrowding the pan: Frying too many pieces at once will cause the oil temperature to drop dramatically. This steams the chicken rather than frying it, leading to a pale, greasy coating. Fry in batches of two for the best results.
- Incorrect Oil Temperature: Guessing the oil temperature is a common pitfall. Using a thermometer removes all guesswork and ensures a perfectly cooked, crispy chicken sandwich every single time.
- Skipping the Rest on a Wire Rack: Placing hot fried chicken directly onto paper towels traps steam, which will quickly make that beautiful crust you worked so hard for go soft. A wire rack is essential for maintaining that crunch.
Delicious Variations to Try
Once you’ve mastered the basic recipe, it’s fun to start experimenting. Here are a few ideas to get you started:
- Nashville Hot Style: After frying, brush the chicken with a spicy oil. Mix 60ml of the hot frying oil with 1 tbsp cayenne pepper, 1 tsp brown sugar, ½ tsp garlic powder, and a pinch of salt. Brush it on and serve with extra pickles.
- Healthier Air Fryer Version: For a lighter option, you can adapt this for the air fryer. Dredge the chicken as instructed, then spray it generously on all sides with cooking oil. Air fry at 200°C for 18-22 minutes, flipping halfway, until golden and cooked through. The crust won’t be quite as craggy, but it’s still very tasty.
- Add Some Cheese: A slice of melted Monterey Jack or a sharp cheddar cheese on top of the hot chicken fillet is a glorious addition.
What to Serve With Your Crispy Chicken Sandwich
A great sandwich deserves a great side dish. Here are a few of our favourites that complement this fried chicken sandwich beautifully:
- Homemade Slaw: A sharp, vinegary coleslaw (rather than a creamy one) provides a fantastic contrast to the rich, fried chicken. The acidity cuts through the fat and refreshes the palate.
- Crispy Potato Wedges: A classic pairing that never fails. For a fun twist, you could serve these alongside my Bacon Brown Sugar Chicken Tenders for the ultimate feast.
- A Cold Drink: A crisp, cold lager or a sharp, fizzy lemonade works wonderfully to cleanse the palate between bites.
