The easiest party appetizer on the planet is also the most delicious. Crockpot Meatballs with Grape Jelly Sauce is a lifesaver for hungry crowds and cocktail parties, so make a double batch!
Add frozen meatballs to crockpot. Add chili sauce and grape jelly. Cover and cook for 2 to 3 hours on HIGH or 4 to 6 hours on LOW, until the sauce is hot. Serve directly from the crockpot with a serving spoon or toothpicks, or transfer to a serving dish.
To sauce the meatballs on the stovetop:
Add meatballs to saucepan. Add chili sauce and grape jelly. Cover and simmer over medium heat until the sauce is hot, about 10 minutes.
In a large bowl, combine beef, pork, bread crumbs, onion, milk, egg, Worcestershire sauce, 1 teaspoon salt, and 1/2 teaspoon pepper.
Using a strong spatula or your hands (I like to wear latex gloves), mix well. Shape the mixture into 1-inch balls (you should have around 48 total).
To fry the meatballs:
Heat vegetable shortening in a large skillet over medium-high heat. Fry the meatballs in batches until browned on all sides and the meatballs are cooked, about 5 to 7 minutes per batch (an internal thermometer should read 155 degrees for 15 seconds). Add more shortening between batches if the skillet looks dry.
To bake the meatballs:
Preheat oven to 400 degrees. Line a rimmed baking sheet with foil and set a rack on top. Arrange meatballs on rack and bake until browned with crispy edges, about 20 minutes (an internal thermometer should read 155 degrees for 15 seconds).
Additional notes:
Sweet chili sauce may be substituted for regular chili sauce. The flavor will be a little different but still delicious!
