In a large mixing bowl, combine ground beef and ground pork carefully. Add breadcrumbs, Parmesan cheese, garlic, onion, eggs, parsley, Italian seasoning, salt, pepper and milk. Mixing different meats together creates richer flavor and softer texture inside the finished meatballs.

Use clean hands or a spoon to mix everything gently until combined. Avoid pressing too hard because overmixing can make meatballs tough instead of tender. The mixture should feel moist, soft, and easy to shape into round meatballs afterward.

Take small portions of the meat mixture and roll into medium-sized balls using your hands. Place each meatball onto a tray or plate. Try keeping similar sizes so they cook evenly and develop beautiful golden color while cooking.

Place a large skillet or Dutch oven over medium heat. Add olive oil and allow it to warm slightly. Properly heated oil helps create golden brown crust outside the meatballs while keeping the inside juicy and flavorful during cooking.

Carefully place the meatballs into the hot pan without overcrowding. Cook each side for several minutes until browned evenly. Browning adds delicious savory flavor and helps the meatballs hold shape while simmering later inside rich tomato sauce.

Pour marinara sauce into the pan gently around the browned meatballs. Reduce the heat to low and let everything simmer together. The sauce absorbs flavor from the meatballs while keeping them moist, juicy and incredibly tender during cooking.

Cover the pan partially and simmer the meatballs for about 20 minutes. Stir gently once or twice during cooking. The meatballs should cook fully inside while soaking up the rich garlic tomato sauce flavors beautifully throughout every bite.

Sprinkle fresh basil and extra Parmesan cheese over the meatballs before serving. The herbs add fresh aroma and bright flavor. These simple toppings make homemade meatballs feel even more comforting, hearty and restaurant-style for family dinners or gatherings.

Serve the meatballs hot with spaghetti, garlic bread or mashed potatoes. The juicy texture and rich tomato sauce taste incredibly comforting together. Every bite feels hearty, savory and homemade, making this recipe perfect for cozy dinners and family meals.
