Creating Slow-Cooker Italian Meatballs is simple when you follow these steps:

1. Prepare the Meat Mixture: In a large bowl, combine the ground beef, ground pork, breadcrumbs, Parmesan cheese, parsley, eggs, garlic, salt, black pepper, oregano, and basil. Mix until well combined.
2. Form the Meatballs: Using your hands, shape the mixture into meatballs, about 1 to 1.5 inches in diameter.
3. Brown the Meatballs (Optional): For added flavor, you can brown the meatballs in a skillet over medium heat for 2-3 minutes on each side. This step is optional but recommended.
4. Place in Slow Cooker: Arrange the meatballs in the slow cooker. You can layer them if necessary.
5. Add Sauce: Pour the marinara sauce over the meatballs, ensuring they are well covered.
6. Cook: Set your slow cooker to low for 6-8 hours or high for 3-4 hours. Cook until the meatballs are thoroughly cooked and tender.
7. Serve: Once cooked, gently stir the meatballs in the sauce before serving. Garnish with fresh basil if desired.
