Making Grape Jelly Meatballs is as easy as following these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Mix the Meatball Ingredients: In a large bowl, combine the ground beef, breadcrumbs, chopped onion, egg, milk, salt, and black pepper. Mix until well combined.
3. Form the Meatballs: Shape the mixture into small meatballs, about 1 inch in diameter. Place them on a baking sheet lined with parchment paper.
4. Bake the Meatballs: Place the meatballs in the preheated oven and bake for about 25 minutes, or until browned and cooked through.
5. Prepare the Sauce: While the meatballs are baking, mix grape jelly and barbecue sauce in a medium saucepan over medium heat. Stir until the jelly has melted and the mixture is well combined.
6. Coat the Meatballs: Once the meatballs are done, remove them from the oven and transfer them to the saucepan. Coat the meatballs well in the grape jelly sauce.
7. Simmer: Reduce the heat and let them simmer in the sauce for an additional 5 minutes to soak up the flavors.
8. Serve: Remove from heat, garnish with fresh parsley if desired, and enjoy!

These steps ensure you create delicious Grape Jelly Meatballs every time.
