Dry the shrimp thoroughly
Moisture left on the shrimp can turn the flour into a paste and cause the coating to slide off.
After peeling and deveining, drain the shrimp well and pat every surface dry with paper towels.
Season according to your Cajun blend
Some Cajun seasonings are mostly spices, while others contain plenty of salt.
Taste or check the label before seasoning the shrimp separately. It is easier to add salt after cooking than to correct an overly salty coating.
Keep the breading station organized
Arrange the flour, egg, and breadcrumbs in that order before you begin.
Use one hand for the flour and breadcrumbs and the other for the egg. This helps prevent the coating from building up heavily on your fingers.
Remove excess flour and egg
Too much flour can leave dry patches beneath the coating, while excess egg can make the breadcrumbs clump.
Shake off the flour and let the extra egg drip back into its bowl before moving the shrimp into the breadcrumbs.
Press the breadcrumbs gently
The breadcrumbs should cover the shrimp without forming an unnecessarily thick shell.
Press just firmly enough to help them adhere, then shake off any loose crumbs before placing the shrimp in the basket.
Leave room around each piece
Arrange the shrimp in a single layer without letting the breaded surfaces overlap.
Cook in batches when necessary. Filling the basket too tightly traps steam and prevents even crisping.
Follow the temperature, but check your air fryer
Cook the shrimp at 200°C (400°F) for 10 minutes, flipping them halfway through.
Air fryers differ in power and basket design, so begin checking slightly early. Remove the shrimp as soon as the coating is golden and the centers are cooked to avoid making them dry or rubbery.
Serve immediately
The coating is crispiest shortly after it leaves the air fryer.
Let the shrimp rest only briefly before serving so steam does not soften the underside.
