I pat each shrimp completely dry with paper towels before doing anything else. Any extra moisture on the surface stops the flour from sticking properly. This one small step makes a noticeable difference in how crisp the final coating turns out.
In a shallow bowl, I mix the flour with sea salt and black pepper until it's evenly combined. This seasoned flour is the very first layer of flavor the shrimp gets. I toss the dried shrimp in it, shaking off any excess before moving on.
Next, I dip the floured shrimp into the beaten egg, making sure each piece is fully coated. The egg acts as the glue that holds the panko crumbs in place during frying. I let any drips fall back into the bowl before the next step.
I press each shrimp gently into the panko crumbs, turning it a few times so every side is covered. Pressing rather than just rolling helps the crumbs really cling on. This is the step that gives the shrimp its signature crunchy shell.
I heat the oil to around 350-375°F in a large skillet before adding the shrimp in small batches. Each piece fries for about a minute and a half to two minutes per side, until deeply golden. I never crowd the pan, since that drops the oil temperature and leads to soggy shrimp.
Once golden, I lift the shrimp out with tongs and set them on a wire rack to drain. This keeps the bottom from steaming and going soft the way paper towels sometimes can. A quick pinch of extra salt while they're still hot finishes them off perfectly.
