Begin by preparing all the ingredients.

Generously season the trimmed baby back ribs with salt and freshly ground black pepper, ensuring they are evenly coated.

Pour ½ cup of water into the base of your slow cooker, then carefully place the seasoned ribs inside. Evenly distribute the sliced onion and minced garlic over the top of the ribs. Secure the lid and cook on Low for 8 hours, or on High for 4 hours, until the ribs are tender and succulent.

As the ribs near the end of their cooking time, preheat your oven to 375°F (190°C) to get it ready for the final step.

Once the ribs are fully cooked, transfer them from the slow cooker to a baking sheet, discarding the onion and garlic. Generously brush the ribs with your favorite barbeque sauce, ensuring they are well coated.

Place the baking sheet in the preheated oven and bake for 10 to 15 minutes, or until the sauce caramelizes beautifully, adhering to the meat and creating a mouthwatering glaze.

Serve the ribs hot and savor the delicious flavors. Enjoy!
