Making tilapia in the air fryer is my secret for an easy meal for busy weeknights. These mild fish fillets cook quickly with minimal effort, and the garlic butter coating makes this a delicious dinner my entire family loves. Works with fresh or frozen tilapia!
In a small bowl, combine the melted butter, smoked paprika, garlic powder, dried thyme, lemon zest, salt, pepper, and red pepper flakes. Stir until combined.
Pat the tilapia fillets completely dry with paper towels.
Brush both sides of each fillet with the garlic butter seasoning mixture.
Spray the air fryer basket with cooking spray. Place the fillets in a single layer, making sure they do not overlap.
Air fry at 400°F for 8 to 10 minutes, or until the fish flakes easily with a fork and reaches an internal temperature of 145°F. Do not flip.
While the fish cooks, whisk together the mayonnaise, olive oil, minced garlic, lemon juice, salt, and pepper in a small bowl.
Serve the tilapia with the garlic lemon aioli, fresh lemon wedges, and fresh thyme, if desired.
Notes
Frozen tilapia: Cook at 400°F for 15 to 17 minutes, or until the fish flakes easily and reaches 145°F.
For best results with frozen fish, quick-thaw the fillets in cold water for about 15 minutes first, then pat dry and cook as directed.
Do not flip the fish. Tilapia is delicate and can break apart easily.
Store leftovers in an airtight container in the refrigerator for up to 2 days.
Reheat in the air fryer at 400°F for 3 to 4 minutes, or until warmed through.
