Prep the shrimp: Pat shrimp dry with paper towels. Moisture is the enemy of crispiness. Lightly season with salt and pepper.
Set up dredging stations: In one shallow bowl, whisk eggs with mayo until smooth.
In a second bowl, mix almond flour, shredded coconut, garlic powder, smoked paprika, a pinch of salt, and a dash of cayenne.
Coat the shrimp: Dip each shrimp in the egg mixture, let excess drip off, then press into the coconut-almond mixture. Pack the coating on gently for full coverage. Place on a sheet pan while you finish the rest.
Choose your cooking method: Air fryer: Preheat to 390°F (200°C).
Lightly oil the basket. Arrange shrimp in a single layer and mist the tops with oil. Cook 6–8 minutes, flipping halfway, until golden and opaque.
Oven: Preheat to 425°F (220°C).
Place shrimp on a wire rack over a parchment-lined tray. Brush or mist with oil. Bake 10–12 minutes, flipping at 7 minutes, until crisp and cooked through.
Skillet: Heat 2–3 tablespoons avocado oil over medium heat.
Fry shrimp 2–3 minutes per side until golden and cooked. Work in batches and don’t crowd the pan.
Finish with freshness: Zest a little lime over the hot shrimp and squeeze a bit of juice for brightness.
Serve: Plate with cilantro, extra lime wedges, and a keto-friendly dipping sauce. Eat while hot and crispy.
