Preparation:

Step 1:
In a small bowl, combine paprika, garlic powder, onion powder, salt, and pepper. Mix well until all the spices are evenly distributed.

Step 2:
Rub the spice mixture all over the lamb ribs, ensuring they are evenly coated. This will add layers of flavor to the meat.

Step 3:
Place the seasoned ribs in the crockpot. Arrange them in a way that they lie flat for even cooking.

Step 4:
In a separate bowl, mix the barbecue sauce, brown sugar, and apple cider vinegar until the sugar is dissolved and the sauce is smooth.

Step 5:
Pour the barbecue sauce mixture over the ribs in the crockpot, making sure to cover them evenly.

Step 6:
Cover the crockpot with a lid and set it to cook on low for 6-8 hours. The slow cooking process allows the ribs to absorb all the flavors and become tender.

Step 7 (Optional):
For a caramelized finish, preheat the oven to broil. Remove the ribs from the crockpot and place them on a baking sheet. Broil for 3-5 minutes, or until the top is slightly crispy and caramelized.
