Sweet and Sour Meatballs in Sauce

Step 1
Preheat oven to 350 degrees F (175 degrees C).

Step 2
Mix the ground beef, eggs, bread crumbs, onion, milk, salt, and black pepper together in a large mixing bowl until evenly combined. Form the mixture into 12 large meatballs. Arrange the meatballs into a 9×13-inch baking dish.

Step 3
Stir the ketchup, tomato sauce, water, brown sugar, white sugar, Worcestershire sauce, Italian seasoning, and chili powder together in a saucepan over medium heat; cook and stir until well combined and hot, about 5 minutes. Pour the tomato sauce mixture over the meatballs in the baking dish. Turn the meatballs to coat in the sauce.

Step 4
Bake in the preheated oven until the meatballs are cooked through and no longer pink in the center, 60 to 90 minutes.
