Crispy Dill Chicken Sandwich

Last summer my roommate brought home an enormous bunch of dill from the farmers market and we spent the entire weekend trying to use it all before it wilted. This chicken sandwich happened after I accidentally dumped way too much fresh dill into the buttermilk marinade, then decided to lean into the herb overload with a matching mayo. The first bite was such a revelation that we made three batches that same week.

I served these at a backyard barbecue last month and watched my friend Alex actually close his eyes at first bite. He grabbed a second sandwich before anyone else had finished their first, which is basically the highest compliment I know how to receive in my kitchen. Something about the combination of hot crispy chicken and cool tangy sauce just works.

Ingredients

• 4 boneless chicken breasts: Pounding them to even thickness helps them cook uniformly and stay juicy
• 1 cup buttermilk: The acid tenderizes the meat while creating the perfect base for herbs to cling to
• Fresh dill: Use the fluffy fronds for maximum flavor impact in both marinade and sauce
• 1 cup all-purpose flour mixed with ½ cup cornstarch: This combo creates an extra crunchy exterior that stays crisp longer
• Smoked paprika: Adds subtle depth and a beautiful golden brown color to the coating
• Vegetable oil: Neutral flavor lets the dill shine while providing high heat stability
• Mayonnaise, lemon juice, and Dijon mustard: The foundation of a sauce that balances richness with brightness
• Brioche buns: Their slight sweetness and buttery crumb make them ideal for holding up to fried chicken
• Dill pickle slices: Essential acidity and crunch to cut through the richness
• Shredded iceberg lettuce: Adds necessary freshness and satisfying texture contrast

Instructions

Marinate the chicken:

Whisk buttermilk with chopped dill, garlic and onion powder, salt and pepper until fragrant. Submerge chicken breasts completely, cover the bowl, and let it sit in the refrigerator for at least 30 minutes, though 4 hours yields even better flavor penetration.

Prepare the coating station:

In a shallow dish, combine flour, cornstarch, smoked paprika, salt and pepper until well blended. This creates the perfectly seasoned crust that will become beautifully golden when fried.

Coat the chicken:

Lift each piece from the marinade, letting excess drip off briefly. Press firmly into the flour mixture, ensuring complete coverage on all sides. Let the coated chicken rest on a wire rack for 5 minutes to help the coating set.

Fry to perfection:

Heat oil until it reaches 175°C (350°F), maintaining temperature throughout cooking. Fry chicken for 4 to 5 minutes per side until deep golden brown and the internal temperature hits 74°C (165°F). Transfer to paper towels to drain.

Make the dill mayo:

Stir together mayonnaise, chopped fresh dill, lemon juice, Dijon mustard, garlic powder, salt and pepper until smooth and bright green speckles appear throughout.

Assemble the sandwiches:

Give brioche buns a quick toast until lightly golden. Spread a generous layer of dill mayo on both halves. Layer lettuce and pickles on the bottom bun, nestle the hot chicken on top, add tomato slices if desired, and crown with the top bun.

My nephew ordered this at a restaurant recently and texted me that it was good but mine was better, which might be the proudest moment of my cooking life. These sandwiches have become the thing my friends request most often, probably because they make any Tuesday dinner feel like a treat.

Getting That Perfect Crisp

The key to restaurant style crunch is letting your breaded chicken rest before hitting the oil. This gives the flour coating time to hydrate slightly from the buttermilk residue, forming a stronger bond with the meat. Do not skip this step unless you enjoy breading floating around in your oil.

Oil Temperature Matters

Invest in a kitchen thermometer if you do not already own one. Maintaining consistent oil temperature prevents soggy, greasy chicken and ensures the exterior browns evenly while the interior cooks through properly. Let the oil return to temperature between batches.

Make It Your Own

Try swapping dill for fresh tarragon in the spring, or add a pinch of cayenne to the flour mixture if you enjoy heat. The buttermilk marinade works beautifully with other herbs and the basic technique adapts easily to different flavor profiles.

• Use chicken thighs instead of breasts for extra juiciness and dark meat flavor
• Make these into sliders with mini buns for party appetizers
• Prep the marinade and sauce the night before for faster weeknight cooking

Hope these sandwiches bring as much joy to your table as they have to mine.

Recipe FAQs

→ How do I get the crispiest chicken coating?

For maximum crunch, double-dip the marinated chicken back into the buttermilk, then coat again in the flour mixture before frying. Letting the breaded pieces rest for 5 minutes also helps the coating adhere better during frying.

→ Can I bake this instead of deep frying?

Yes, arrange breaded chicken on a wire rack over a baking sheet and bake at 200°C (400°F) for 20-25 minutes, flipping halfway. The texture won't be quite as crunchy, but spraying with oil before baking helps achieve better crispiness.

→ What can I use instead of buttermilk?

Mix 1 cup regular milk with 1 tablespoon lemon juice or white vinegar. Let it sit for 5-10 minutes until thickened. This creates a similar acidity level that tenderizes the chicken while helping the breading stick.

→ How long should I marinate the chicken?

Marinate for at least 30 minutes to absorb the dill and savory spices. For deeper flavor penetration, marinate up to 4 hours in the refrigerator. Beyond that, the acidity may start breaking down the meat texture too much.

→ What oil temperature is best for frying?

Maintain oil at 175°C (350°F) throughout frying. If the oil is too cool, the coating becomes soggy; too hot and the outside burns before the inside cooks through. Use a kitchen thermometer for accuracy.

→ Can I make the dill mayo ahead of time?

Absolutely. The dill mayo actually tastes better after resting in the fridge for a few hours or overnight as the flavors meld. Store in an airtight container for up to one week.
