How I Discovered This Ultra Crunchy Fried Chicken Burger

The first time I bit into what I now call my Ultra Crunchy Fried Chicken Burger I swear I heard that satisfying rasp of crust against teeth and the kitchen suddenly smelled like a festival. It started as a weekend experiment: I had 2 x 250g/8oz chicken breast (I use this) and 4 boneless thigh fillets in the fridge, and a jar of buttermilk that needed using. If you like deep-fried comfort and hearty sandwiches, you might also enjoy a different kind of fried chicken recipe I sometimes turn to: a classic chicken fried chicken for a change of pace. That little detour helped me figure out what texture I wanted from the meat before I even thought about the coating.

The Ingredients I Keep on Hand

I talk through the ingredients like I would if you were here and we were assembling them on the counter. For the chicken I use 2 x 250g/8oz chicken breast ((I use this)) plus 4 boneless thigh fillets. The marinade is simple: 3/4 cup buttermilk ((Note 1 for sub)), 1 1/2 tsp cooking / kosher salt and 1 large egg. For the buns and fillings I like 4 soft buns (, split and lightly toasted (mine are 10cm/4")), 2 – 3 cups iceberg lettuce (, finely sliced (or other leafy greens of choice)), 2 tomatoes (, sliced (optional, sometimes I do)) and 2 gherkins / dill pickles (, sliced on an angle). The spread is 2/3 cup mayonnaise (, preferably whole egg) mixed with 3/4 tsp garlic (, finely grated (1 clove)). The crunchy coating is where the magic happens: 3/4 cup flour (, plain / all purpose), 1/4 cup corn flour / cornstarch, 1/4 tsp celery salt ((or heaped 1/8 tsp celery seed)), 1/2 tsp sweet paprika, 1/8 tsp cayenne pepper ((inc to 1/2 tsp for spicy ZINGER burger!)), 1/2 tsp onion powder, 1 tsp garlic powder, 1/4 tsp mustard powder, 1/4 tsp ginger powder, 1/2 tsp dried thyme, 1/2 tsp dried oregano, 1/2 tsp cooking salt / kosher salt and 1 1/2 tsp black pepper. Finally you need 3 cups vegetable oil ((or canola or peanut) (2.5cm/1" depth in cooking vessel)) for frying.

The Little Tricks That Give It the Crackle

Here is the shortform of how I think about the process: pound chicken to 1cm / 0.4" thickness, trim, marinade 3 – 24 hrs. Mix coating and seasoning, mix in 2 tbsp marinade. Coat chicken, fry at 180°C/350°F for 4 min (don’t touch for first 90 sec). Assemble. That quick line is my mental checklist, but the real trick is the tiny steps in between.

First, cover the chicken with a freezer bag or plastic sheet and pound to 1cm / 0.4" even thickness. Trim the pieces so they are just a touch larger than the bun—those offcuts are too good to waste; I toss them into a stir fry later, or my dog Dozer gets very happy. Next whisk the marinade ingredients (buttermilk, egg, salt) in a bowl, add the chicken and toss. Let it sit in the fridge for at least 3 hours, but I often leave it overnight. Do not go beyond 24 hrs because the texture starts to go mushy.

The other small thing that changes everything is the coating method. Mix your 3/4 cup flour and 1/4 cup cornflour with all the seasoning ingredients listed above. Then drizzle over 2 tablespoons of the marinade and use your fingers to mix through so it forms lumps. Those little lumps stick to the chicken and fry up into the most incredible crunchy bits. I cannot stress this enough: those lumps are not mistakes, they are features.

A couple of quick tips I always tell friends: rinse and dry your lettuce right before assembling so it’s crisp; if you need a buttermilk substitute, mix milk with a tablespoon of vinegar or lemon juice and let it sit for 5 minutes; and don’t overcrowd the pot when frying—two pieces at a time is my usual.

Step-by-step: How I Cook It

When I actually cook it, I heat oil in a large heavy based pot over medium high heat to 180°C/350°F (Note 2). While the oil comes up to temperature, I make the garlic mayo by mixing 2/3 cup mayonnaise and 3/4 tsp finely grated garlic in a small bowl, then refrigerate it until assembly. To coat the chicken pick up a piece and let excess marinade drip off, then press it into the flour coating so the lumps adhere. Shake off the excess and gently lower into the oil.

Fry for about 2 minutes on each side until the crust is a golden, deep tan. Critically, do not touch the piece for the first 90 seconds so the crust can set. I usually fry two pieces at a time and, once golden, lift them onto paper towels to drain. Cook the remaining chicken the same way. The whole fry for each piece is about 4 minutes total at 180°C/350°F, but if you have a meat thermometer aim for an internal temperature of around 74°C/165°F to be safe.

Assemble immediately. Smear garlic mayo on top and bottom buns, pile finely sliced iceberg lettuce on the base, add tomato if you like that juiciness, then the chicken and a few angled slices of gherkin for a bright contrast. Put the lid on, press down slightly and sink your teeth in.

A Few Ways I Make It My Own and Store Leftovers

I love this recipe because the contrast between the hot, crunchy, well-seasoned chicken and the cool garlicky mayo is so satisfying. If you want to change it up, there are a couple of variations I switch between. For a spicy ZINGER-style burger I up the cayenne to 1/2 tsp and add extra paprika for color. For a more herbaceous twist I fold chopped fresh parsley or tarragon into the mayo. If you prefer a lighter sandwich, use just the breasts and skip the thighs.

Leftovers keep well for a day or two in the fridge. I wrap each sandwich tightly or store chicken separately in an airtight container. To reheat and try to recover the crunch, I preheat the oven to 200°C/400°F and put the chicken on a wire rack for about 8 minutes until hot and crisp again. You can also slice leftover chicken and toss it into fried rice; sometimes I pair it with a quick chicken fried rice with vegetables or even a garlicky rice like crispy garlic chicken fried rice when I want a heartier meal.

How do you know you’ve done it right? The crust should be a deep golden brown and make a clear crackle when you bite. The meat inside should be juicy but cooked through. The smell of frying spices and garlic is a good indicator that everything is coming together.

I have a few habits that help each batch turn out: preheat the oil and monitor it, always press the flour onto the surface so it adheres, and keep a small bowl of hot water nearby to wipe hands when the coating gets messy. Those are small things, but they save time and keep the kitchen much cleaner.
