Preheat your oven to 350�F (175�C). Line a baking sheet with parchment paper or lightly grease it to prevent sticking.
In a large mixing bowl, combine the ground meat, breadcrumbs, eggs, finely chopped onion, minced garlic, salt, and pepper. Mix well until all ingredients are evenly incorporated.
Using your hands, shape the mixture into meatballs of your desired size. Aim for uniformity to ensure even cooking.
Place the formed meatballs onto the prepared baking sheet, spacing them evenly apart.
Bake the meatballs in the preheated oven for 20-25 minutes, or until they are cooked through and golden brown.
While the meatballs are baking, prepare the sauce. In a saucepan over medium heat, combine grape jelly and barbecue sauce. Stir occasionally until the jelly is melted and the sauce is smooth.
Once the meatballs are cooked, transfer them to a serving dish. Pour the grape jelly barbecue sauce over the meatballs, ensuring they are evenly coated.
Serve the Grape Jelly Meatballs hot, and enjoy the delicious combination of sweet and savory flavors!
