how long should a rub be on ribs before you grill them
Slow Roasting the Ribs. Another way to precook ribs for the grill is in your oven or slow cooker. Season the ribs ahead of time with a dry rub made from herbs and spices or dried spicy dip mix, then place them on a sheet pan or in your slow cooker. Use the low setting on the slow cooker, or preheat your oven to 250 degrees Fahrenheit. Slow-roast the ribs until they are nearly fork-tender, usually for 2 1/2 to 4 hours depending on the size of the rack. Transfer the ribs to your grill, and finish them over direct heat with your favorite sauce.
