Preheat and prep: Heat the oven to 400°F (200°C). Line a rimmed baking sheet with parchment or lightly oil it.
This helps the meatballs brown and release easily.
Mix the glaze: In a small bowl, whisk the BBQ sauce, apple cider vinegar, Dijon, honey, and liquid smoke. Set aside.
Make the meatball mixture: In a large bowl, combine ground turkey, Greek yogurt, egg whites, oats or breadcrumbs, onion, garlic, Worcestershire, smoked paprika, onion powder, garlic powder, salt, and pepper. Mix gently with a fork or your hands until just combined.
Do not overmix or the meatballs can turn dense.
Shape the meatballs: Lightly wet your hands and form 20–24 meatballs, about 1.5 inches wide. Place them evenly on the baking sheet with a bit of space between each.
Bake: Bake for 12 minutes, then remove from the oven.
Glaze and finish: Brush the meatballs generously with the BBQ glaze. Return to the oven and bake another 6–8 minutes, until cooked through and glossy.
Internal temperature should reach 165°F (74°C) for turkey or 160°F (71°C) for beef.
Optional broil: For a stickier finish, switch to broil for 1–2 minutes. Watch closely to avoid burning.
Rest and serve: Let the meatballs rest for 3–5 minutes. Garnish with green onions or sesame seeds if you like.
Serve with rice, roasted vegetables, or a crisp salad.
