Make the Herb Butter: In a small bowl, combine the softened butter, minced garlic, chopped parsley, chopped dill, lemon zest, and a pinch of salt and pepper. Mix until well combined. Set aside.
Prepare the Tilapia: Pat the tilapia fillets dry with paper towels. Drizzle olive oil over the fillets and rub to coat evenly. Sprinkle paprika, onion powder, and a little more salt and pepper over both sides of the fillets.
Prepare the Crispy Edamame: In a medium bowl, toss the thawed edamame with olive oil, sea salt, garlic powder, and chili flakes (if using) until evenly coated.
Air Fry the Edamame: Preheat your air fryer to 400. Place the edamame in the air fryer basket in a single layer. Cook for 8-10 minutes, shaking the basket halfway through, until they're crispy and slightly golden. Remove and set aside.
Air Fry the Tilapia: Place the tilapia fillets in the air fryer basket (you may need to do this in batches depending on the size of your air fryer) and spread a generous amount of the herb butter on top of each fillet. Cook in the air fryer at 400 for 8-10 minutes, or until the fish flakes easily with a fork and is cooked through.
Serve: Once the tilapia is done, transfer it to plates, and serve immediately with the crispy edamame on the side. You can garnish with additional fresh herbs or lemon wedges for a burst of freshness.
