How can I achieve tender and flavorful slow-cooked ribs in the oven?

To achieve tender and flavorful slow-cooked ribs in the oven, first season the ribs generously with a dry rub or marinade. Then, cook the ribs at a low temperature (around 250F) for several hours, allowing the meat to become tender and absorb the flavors. You can also baste the ribs with a sauce or liquid to keep them moist during cooking. Finally, finish the ribs under the broiler or on the grill to caramelize the outside and add a delicious crust.
