Making Slow Cooker BBQ Ribs is simple when you follow these steps:

1. Prep the Ribs: Remove the membrane from the back of the ribs for better flavor absorption.
2. Mix the Dry Ingredients: In a small bowl, combine brown sugar, garlic powder, onion powder, smoked paprika, salt, black pepper, and red pepper flakes if using.
3. Season the Ribs: Rub the dry spice mixture evenly over both sides of the ribs.
4. Prepare the Sauce: In another bowl, mix the BBQ sauce, apple cider vinegar, and Worcestershire sauce.
5. Layer in the Slow Cooker: Place the ribs in the slow cooker. If needed, cut them into sections to fit.
6. Add the Sauce: Pour half of the BBQ sauce mixture over the ribs, ensuring they are well coated.
7. Cook the Ribs: Cover and cook on low for 6 to 8 hours or on high for 3 to 4 hours until tender.
8. Baste the Ribs: About 30 minutes before serving, brush the remaining BBQ sauce over the ribs for added flavor.
9. Serve: Once cooked, carefully remove the ribs from the slow cooker and let them rest for a few minutes before slicing.
