Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a large bowl, combine chicken wings with flour, kosher salt, black pepper, garlic powder, and onion powder. Toss to coat evenly.
Arrange the coated wings in a single layer on the prepared baking sheet.
Bake for 20 minutes, then flip the wings and bake for another 25-30 minutes, or until golden brown and cooked through.
While the wings are baking, prepare the sauce: In a small bowl, whisk together melted butter, lemon juice, lemon zest, lemon pepper seasoning, and salt.
Once the wings are cooked, transfer them to a clean bowl and pour the lemon pepper sauce over them. Toss to coat.
Serve hot.
Notes
For extra crispy wings, you can bake them at 425°F (220°C) for the last 10-15 minutes. Garnish with fresh parsley if desired.
