Making Classic Italian Meatballs is easy if you follow these steps carefully:

1. Preheat Oven: Start by preheating your oven to 375°F (190°C).
2. Mix the Meat: In a large bowl, combine the ground beef and ground pork. Mix gently until blended.
3. Add Breadcrumbs and Cheese: Stir in fresh breadcrumbs and grated Parmesan cheese. Mix everything well.
4. Combine Herbs and Spices: Add chopped parsley, minced garlic, salt, black pepper, and Italian seasoning. Stir until evenly distributed.
5. Incorporate Egg and Milk: Crack the egg into the mixture and pour in the milk. Combine all ingredients until just mixed. Avoid overworking the meat to keep the meatballs tender.
6. Form Meatballs: Shape the mixture into balls about the size of a golf ball and place them on a greased baking sheet.
7. Bake the Meatballs: Bake in the preheated oven for 20-25 minutes or until they are browned and cooked through.
8. Simmer in Sauce: While the meatballs are baking, heat the marinara sauce in a large pot. Once the meatballs are done, gently add them to the sauce and simmer for an additional 10-15 minutes.

These steps will help you create classic, tender meatballs that are packed full of flavor.
