Enjoy a taste of nostalgia with these delightfully tender and flavorful sweet and sour meatballs. The perfect balance of savory beef and tangy sauce come together in a hearty dish that's easy to make and perfect for sharing with loved ones. No wonder it's a beloved family favorite!
In a large bowl, combine the lean ground beef, finely chopped onion, minced garlic, dried mixed herbs, tomato paste, beaten egg, freshly ground black pepper, and sea salt. Mix thoroughly with your hands.
Form the mixture into 48 one-inch round meatballs and set aside on a plate.
Heat a nonstick frying pan and brown the meatballs in batches on the outside. Transfer them to an ovenproof casserole dish.
In a medium-sized saucepan, combine the dark brown sugar, white vinegar, water, mustard powder, and tomato ketchup. Whisk over medium heat until the sugar is dissolved and the mixture starts to bubble.
Dissolve the cornstarch in the cold water, and then whisk the cornstarch mixture into the sauce to thicken it. Pour the thickened sauce over the meatballs in the casserole dish.
Bake the meatballs in the preheated oven for 30 minutes.
Serve the sweet and sour meatballs with steamed rice and a green vegetable of your choice.
