Preheat your grill to 425°F (220°C).
In a small bowl, combine the lemon zest, black pepper, kosher salt, minced garlic, and onion powder.
Pat the chicken wings completely dry using paper towels.
Drizzle or spray the wings with avocado oil.
Coat the wings evenly with the homemade lemon pepper seasoning.
Arrange the Lemon Pepper Wings directly on the grill grates.
Grill for 15–20 minutes, turning every 3–5 minutes until the skin is crispy and the internal temperature reaches 170–175°F (77–79°C).
In a large bowl, whisk together the melted butter and fresh lemon juice.
Transfer the cooked wings directly into the bowl and toss until evenly coated.
Garnish with extra cracked black pepper, fresh lemon zest, or chopped parsley if desired.
Serve immediately while hot and crispy
