Equipment

To prepare Shrimp Katsu Burgers smoothly, gather the right tools before starting. A food processor is essential for blending part of the shrimp into a cohesive mixture. A sharp chef knife helps with trimming and chopping shrimp evenly. Mixing bowls are needed for breading and slaw preparation. Use shallow bowls for flour, eggs, and panko to keep the coating process tidy. A heavy bottom skillet or pot ensures even frying and stable oil temperature. A slotted spoon or spider strainer helps lift patties safely from the oil. Paper towels are useful for draining excess oil, and a thermometer is helpful to monitor frying temperature accurately.

Ingredients List

For the shrimp patties, you will need one half cup finely chopped onion, one tablespoon cornstarch, one and one quarter pounds large shrimp peeled, deveined, and tails removed, divided into two portions, and kosher salt to season.
For the coating, prepare two large eggs, one quarter cup all purpose flour, and one cup panko bread crumbs for extra crunch.
For frying, use two cups vegetable oil with a neutral flavor.
For the slaw, you will need two cups coleslaw mix, two tablespoons mayonnaise such as Kewpie style mayo, one tablespoon fresh lime juice, and salt to taste.
For assembly, use four brioche style burger buns such as Pepperidge Farm Brioche Burger Buns, Martin’s Potato Rolls, or Canyon Bakehouse Brioche Style Buns.
For finishing, use a smooth drizzle of Kikkoman Tonkatsu Sauce, Otafuku Tonkatsu Sauce, Heinz Tomato Ketchup, or Primal Kitchen Unsweetened Ketchup.

Step by Step Preparation

Begin by preparing the shrimp base. Place the chopped onion, cornstarch, and about two thirds of the shrimp into a food processor. Add a quarter teaspoon salt. Pulse for about thirty seconds until the mixture forms a thick paste. This paste acts as the binder and keeps the patties juicy during frying.

Add the remaining one third of shrimp to the processor. Pulse just two or three times until the shrimp pieces are chopped into small chunks. Stop immediately once they are evenly distributed. Over processing will turn the mixture into a paste, which reduces texture.

Transfer the shrimp mixture to a bowl. Lightly dampen your hands with water and divide the mixture into four equal portions. Shape each portion into a patty about half an inch thick. Place patties on a plate, cover, and refrigerate for at least thirty minutes. Chilling helps the patties hold their shape during breading and frying.
While the patties chill, prepare the slaw. In a medium bowl, combine the coleslaw mix, mayonnaise, and fresh lime juice. Toss gently until coated. Season lightly with salt, then refrigerate to keep it crisp and refreshing.

Set up a breading station. Place flour in one shallow bowl. In another shallow bowl, beat the eggs until smooth. In a third bowl, add the panko bread crumbs.
Remove the chilled shrimp patties from the refrigerator. Working one at a time, coat each patty lightly in flour, shaking off any excess. Dip it into the beaten egg, allowing extra egg to drip away. Finally, press the patty gently into the panko, coating all sides evenly. Place breaded patties on a clean plate.

Heat the vegetable oil in a heavy pot or deep skillet to a depth of about half an inch. Heat over medium until the oil shimmers. The ideal temperature is around three hundred fifty degrees Fahrenheit.

Carefully place patties into the oil, working in batches to avoid overcrowding. Fry for one to two minutes per side until golden brown and cooked through. The shrimp should feel firm but still juicy inside.

Transfer cooked patties to a paper towel lined plate to drain excess oil.

To assemble, place each shrimp katsu patty on the bottom bun. Drizzle generously with tonkatsu sauce or ketchup. Add a mound of coleslaw, then cap with the top bun. Serve immediately while hot and crispy.

Tips and Tricks

For the best Shrimp Katsu Burgers, keep the shrimp very cold before processing. Cold shrimp blend more cleanly and prevent a gummy texture.
Do not skip the chilling step. Refrigeration helps the cornstarch and shrimp proteins bind properly.

When breading, use one hand for dry ingredients and one for wet ingredients to avoid clumping.

Maintain consistent oil temperature. If the oil is too hot, the coating browns before the shrimp cooks. If too cool, the patties absorb oil and become greasy.
Use panko rather than regular bread crumbs. Panko creates larger air pockets, resulting in a lighter, crunchier crust.

Season lightly at each step. Proper seasoning enhances flavor without overpowering the shrimp.

Toast the buns lightly before assembling to prevent sogginess.
If you want extra crunch, double coat the patties by repeating the egg and panko steps once more.

Notes

Shrimp Katsu Burgers are inspired by classic katsu techniques adapted for seafood. The combination of shrimp paste and chopped shrimp delivers both structure and texture.

Coleslaw provides acidity and crunch that balance the fried patty. Lime juice adds brightness that cuts through richness.

Brioche style buns offer a soft, slightly sweet contrast to the savory shrimp.
You can prepare the shrimp patties a day ahead and keep them covered in the refrigerator. Bread them just before frying for best results.

Avoid over processing the shrimp, as this changes the mouthfeel.

Always pat shrimp dry before processing to control moisture levels.

Serve immediately after frying for optimal crispness.

Storage

Shrimp Katsu Burgers are best enjoyed fresh, but leftovers can be stored properly.
Cooked patties can be refrigerated in an airtight container for up to two days. Allow them to cool completely before storing.

To reheat, place patties in a hot oven at three hundred seventy five degrees Fahrenheit for about eight minutes to restore crispness.

Avoid microwaving, as it softens the coating.

Uncooked patties can be frozen before breading. Wrap tightly and freeze for up to one month. Thaw overnight in the refrigerator before breading and frying.
Store slaw separately and add fresh before serving.

Variations

For a spicy version, mix a teaspoon of hot sauce such as Texas Pete Original Hot Sauce or Crystal Hot Sauce into the shrimp mixture.

Add finely chopped scallions or cilantro for a fresh herbal note.

Swap the slaw dressing with a light yogurt based sauce for a tangy profile.

Serve the shrimp katsu patty over rice with slaw on top for a burger bowl experience.

Use sesame seeds mixed into the panko for added aroma and crunch.

Serving Suggestions

Serve Shrimp Katsu Burgers with oven roasted fries, sweet potato wedges, or a crisp cucumber salad.
A sparkling citrus drink or iced tea pairs well with the crunchy texture and bright flavors.
