I pat the wings dry, place them in a large bowl, add the vegetable oil, and toss with the lemon-pepper seasoning until evenly coated. This quick coating helps the seasoning cling and prevents flare-ups from excessive oil on the grill.
I preheat the grill to about 375°F and place the wings directly over medium heat, cooking for about 20 minutes first. After the initial sear I turn them and continue grilling for another 15–20 minutes, checking for golden, slightly charred skin and an internal temperature near 165°F.
While the wings finish, I gently melt butter and whisk in an extra pinch of lemon-pepper seasoning. Once the wings are done, I drizzle the butter over them and toss to coat—this adds shine and boosts the citrus-pepper flavor without making the skin soggy.
