Prep the shrimp: Pat shrimp very dry with paper towels. Dry shrimp sear better and take on more flavor.
Preheat the air fryer: Set to 390°F (200°C) for 3 minutes so the basket is hot when the shrimp go in.
Make the coating: In a large bowl, whisk melted butter, olive oil, garlic, lemon zest, lemon juice, paprika, red pepper flakes, salt, and pepper.
Add Parmesan and panko: Stir in Parmesan and panko until a moist crumb forms.
It should lightly cling to the shrimp without clumping.
Toss the shrimp: Add shrimp to the bowl and gently toss until evenly coated. If using veggies, toss them separately with a drizzle of oil, a pinch of salt, and a little Parmesan.
Load the basket: Arrange shrimp in a single layer in the preheated basket. If adding veggies, place them around the edges or cook in batches to avoid overcrowding.
Air fry: Cook for 5–7 minutes, shaking or flipping once halfway.
Shrimp are done when pink, opaque, and just firm. Avoid overcooking.
Finish and garnish: Transfer to a plate. Sprinkle with parsley and extra Parmesan.
Serve with lemon wedges.
Make it a full dinner: Serve over rice, orzo, or a light salad. Garlic bread is a great side if you want something extra.
