- 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.
