You grab chicken thighs, hit them with a mayo marinade, and 30 minutes on a hot grill later you're pulling off skewers with real char and garlic parmesan butter coated all the way through. The double-baste at the end is your move; that's what makes every bite taste insanely good.

Instructions
Marinate
Combine olive oil, mayonnaise, lemon juice, garlic powder, kosher salt, black pepper, dried parsley, and paprika in a large bowl. Add chicken cubes and toss until fully coated. Cover and refrigerate for at least 30 minutes, up to 4 hours.
Thread
Thread marinated chicken onto metal or soaked wooden skewers, packing cubes close with no gaps between pieces.
Preheat
Heat grill to medium-high, 400–450°F. Clean and oil the grates.
Make the Butter
Combine butter, lemon juice, minced garlic, Parmesan, kosher salt, red pepper flakes, and chopped parsley in a small saucepan over low heat. Stir until melted and smooth. Split into two portions before grilling.
Grill
Place skewers over direct heat. Turn every 2–3 minutes for even char on all sides. Grill 10–14 minutes total until internal temperature reaches 165°F.
Baste and Finish
In the final 60 seconds on the grill, brush skewers with the first portion of garlic parmesan butter. Pull at 165°F and immediately coat with the second clean portion of butter off the heat. Garnish with fresh parsley and serve with lemon wedges.
Notes
Marinating 2–4 hours gives noticeably better flavor than the 30-minute minimum.
Soak wooden skewers for at least 30 minutes before threading to prevent burning on the grate.
Always split the butter sauce into two portions before cooking - one for the grill baste, one for finishing. Never baste raw chicken with the sauce you'll serve.
Chicken thighs stay juicy at 175°F, and the texture improves past the 165°F minimum. Don't be afraid to push them.
Gas grill: Preheat all burners to medium-high for 10–15 minutes. Cook over direct heat. For added smoke flavor, set a foil packet of soaked wood chips (hickory or post oak work well) directly on the grates near the burners with a few holes punched in the top - it adds the smoke depth gas grills don't get on their own.
Charcoal grill: Bank the coals to one side for a two-zone fire. Grill the skewers over the hot side for direct char. Use the cooler side to manage any flare-ups from the butter baste in the final minute. The charcoal smoke layers with the garlic parmesan butter in a way that gas just doesn't replicate.
