About halfway through rolling, heat the oil in a large skillet over medium-high heat and preheat the oven to 400 degrees. Once all meatballs are rolled, carefully place in the hot oil. Brown for 2 to 3 minutes, then flip and cook for another 1 to 2 minutes on the second side. Transfer to the prepared baking sheet and finish cooking in the oven for 8 minutes.
Serve with tomato sauce as an appetizer or with spaghetti and tomato sauce for a full meal.
To freeze: Lay out the meatballs in a single layer on a parchment-lined baking sheet. Freeze overnight or until frozen solid. Transfer to freezer-safe resealable plastic bag and store in freezer. For best quality, the meatballs will last up to 4 months in the freezer.
To reheat from frozen: Heat in a sauce on the stovetop or in a preheated 350-degree oven for 10 to 15 minutes, or until hot in the middle. Or you can microwave the meatballs for 3 to 4 minutes on high in a single layer with a little water at the bottom of a microwave-safe plate, or in a slow cooker with sauce.
