Set your oven to 350F.
While it’s warming, mix your beef, rice, milk, onion, parsley, and 1 tsp of the Worchestersauce together. Make sure everything is well-combined.
Shape into your meatballs, about 1 ½” in size.
Warm the olive oil over medium heat. Lay the meatballs to sautee inside. Leave yourself enough room to turn them. You may have to do two batches.
When they are golden (about 10 minutes), transfer them to an oil-treated baking dish.
Whip up your sauce in a blender with all the ingredients, including the last 2 tsp of Worcestershire sauce.
Pour some sauce on the bottom of the baking dish.
Add the meatballs and cover them evenly with the rest of the sauce.
Cover the dish with aluminum foil.
Bake for 40 minutes, then remove the foil.
Continue baking uncovered for 15 minutes.**
** If you’d like to add cheese, now’s the time. Mozzarella is an ideal choice. These go well with a pasta salad.
