Preheat the oven to 400 degrees F. Line a baking sheet with parchment paper.
In a large bowl combine the ground beef, breadcrumbs, egg, onion, smoked paprika, garlic powder, salt, and black pepper. Mix until just combined.
Form the mixture into 16 to 20 meatballs and place them on the prepared baking sheet. Bake for 15 minutes until lightly browned.
While the meatballs bake, warm the BBQ sauce and liquid smoke in a saucepan over medium heat. Stir until the sauce is heated through.
Add the baked meatballs to the saucepan and stir gently to coat them evenly. Cook for 5 minutes on low heat so the flavors combine.
Transfer the meatballs to a serving bowl and sprinkle with chopped parsley.
