Preheat your oven to 400°F.
In a large bowl, combine ground chicken, breadcrumbs, Parmesan cheese, parsley, egg, garlic, onion powder, salt, black pepper, and smoked paprika. Mix until all ingredients are well combined.
Using your hands, form the mixture into meatballs, about 1 inch in diameter. Place the meatballs on a baking sheet lined with parchment paper.
Drizzle the olive oil over the meatballs to help them brown. Bake in the preheated oven for 20 minutes or until cooked through and golden brown.
While the meatballs are baking, heat the BBQ sauce in a small saucepan over medium heat until warm.
Once the meatballs are done, remove them from the oven and toss them in the warm BBQ sauce until well coated.
Serve immediately, garnished with additional parsley if desired.
