Preheat oven to 350°F.
Put all ingredients into the bowl of a stand mixer. Using the paddle attachment, mix all ingredients at medium speed just until fully combined. Do not over mix as this will make your meatballs more dense.
1 lbs ground pork, 1 egg, 1/8 cup milk, ¼ cup bread crumbs, ½ cup onion, 1 tsp Worcestershire sauce, 1 Tbsp fresh parsley, 1 tsp salt, ½ tsp pepper
Line a cookie sheet with parchment paper or a silicone baking mat.
Roll the meat mixture into golf ball-sized balls. I use a tablespoon measuring spoon as a scoop without leveling it off – approximately 1 ½ tablespoon of meat mixture per meatball. Roll them in your hand to shape the balls.
Place the meatballs on a cookie sheet lined with parchment paper or a silicone baking mat.
Bake at 350°F for 20-25 minutes or until the temperature in the center reaches 160°F. The timing will vary depending on the size of each meatball. It’s important to make them all even to ensure they are all cooked to the right temperature.
Cool the meatballs on the cookie sheet. Once cooled, place a cookie sheet in the freezer for an hour. After an hour, transfer meatballs to a Ziploc or reusable silicone bag.
