This is the ultimate comfort food meatball recipe, perfect for dinner parties. You can bake them ahead of time and simmer them in sauce for an hour before serving to warm them up.
1. Preheat oven to 350°F; soak oats in milk and set aside for at least 5 minutes. 2. Mix together the ground beef, pork sausage, parsley, eggs, garlic, white wine, Parmesan cheese, olive oil, salt and pepper; drain excess milk out of the oats and then add them to the meat mixture; mix until evenly combined. 3. Form slightly smaller than tennis ball shape balls and place onto a baking sheet (the recipe yields 9 balls). 4. Bake at 350°F for 30 minutes, check with meat thermometer to ensure meat is at least 165°F. 5. Place into a pot of marinara sauce and serve immediately or simmer for up to 1 hour.
