Preheat the oven to 400 degrees. Drizzle the oil on the baking sheet and spread it evenly over its surface.
Combine the flour, garlic powder, black pepper, and sea salt, to taste in a large zip lock bag; seal and mix until well combined.
Add a large handful of wings to the flour mixture and toss until evenly coated.
Remove from the flour shaking excess off; place skin side UP on the prepared baking sheet without crowding them. Repeat with the remaining wings. Discard any leftover flour.
Place the baking sheet into the oven and bake the wings undisturbed for 30 minutes.
After 30 minutes, carefully flip the wings over and continue to bake for another 15 minutes. Remove from the oven and place on paper towels to drain grease.
Make the lemon garlic butter by combining the hot melted butter, garlic, parsley, lemon zest, and juice in a small bowl; whisk until well combined.
Place the wings in a large bowl then drizzle the well-whisked lemon garlic butter on the wings then toss to coat evenly. Serve immediately with fresh parmesan sprinkled on top, if desired. Enjoy.
