Creating Slow Cooker Apple Butter Meatballs involves a series of simple steps:

1. Combine Ingredients: In a large bowl, combine the ground beef, breadcrumbs, grated Parmesan cheese, chopped onion, minced garlic, salt, pepper, and dried thyme. Mix well until fully incorporated.
2. Form Meatballs: Shape the mixture into meatballs, about 1 inch in diameter. You should get approximately 24-30 meatballs, depending on your preference for size.
3. Prepare Sauce: In a separate bowl, mix together the apple butter, BBQ sauce, Worcestershire sauce, and apple cider vinegar. Stir until well combined.
4. Add to Slow Cooker: Pour half of the sauce mixture into the bottom of the slow cooker. Then, place all the meatballs on top of the sauce.
5. Add Remaining Sauce: Pour the remaining sauce over the meatballs, ensuring they are well-coated.
6. Cook: Cover the slow cooker and cook on low for 4-6 hours or high for 2-3 hours, until the meatballs are cooked through and tender.
7. Garnish: Once cooked, gently stir the meatballs in the sauce to coat them evenly. Serve hot, garnished with fresh parsley if desired.

With these straightforward steps, you’ll have a dish that not only fills your home with delightful aromas but also pleases every palate at your dining table.
