Prep the shrimp: Pat the shrimp very dry with paper towels.
Dry shrimp crisp better and don’t steam in the air fryer.
Season the coating: In a bowl, mix 1/3 cup cornstarch, 1 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/2 teaspoon paprika, 3/4 teaspoon kosher salt, and 1/4 teaspoon black pepper.
Coat the shrimp: Toss the shrimp in the seasoned cornstarch until lightly and evenly coated. Shake off any excess.
Preheat the air fryer: Set it to 390–400°F (200–205°C) for 3–5 minutes. A hot basket helps the shrimp crisp quickly.
Oil the basket: Lightly spray the basket with oil.
Arrange the shrimp in a single layer with a little space between them. Work in batches if needed.
Air fry: Cook for 3 minutes. Flip or shake the basket, then cook another 2–4 minutes until the shrimp are opaque and lightly crisp around the edges. Don’t overcook—they go rubbery fast.
Make the Buffalo sauce: While the shrimp cook, melt 3 tablespoons butter.
Stir in 1/3 to 1/2 cup Buffalo hot sauce and 1 teaspoon honey or brown sugar (optional, for balance). Taste and adjust heat.
Toss and finish: Add hot shrimp to a bowl, pour over the Buffalo sauce, and toss to coat. Squeeze in a little lemon or lime for brightness.
Garnish with chopped parsley or chives.
Serve: Plate immediately with celery and your favorite ranch or blue cheese. They’re best hot and crisp.
