Broil the ribs for about 5 minutes, until the sugar in the dry rub is bubbling and the ribs are evenly browned. Bake the ribs: Set the oven to 300°F. Move the ribs to an oven rack in the middle of the oven. Roast for 2 1/2 to 3 hours for spare ribs or 1 1/2 to 2 hours for baby back ribs. Halfway through cooking, cover the ribs with aluminum foil to protect them from drying out. Repeat with the other rack of ribs, dry rub and foil. Place both baking sheets of ribs into the preheated oven. Bake for 3 1/2 to 4 hours, or until ribs are falling-apart tender. 4. Open up the rib packages, gently transfer the ribs to a cutting board and cut into one or two-rib chunks. 1 Place the ribs in the oven. 2  Cook ribs for 2-1/2 to 4 hours. 3  After about 2-1/2 hours, open a corner of one of your foil packets and test the ribs with a fork. 4  If they are tender, move on to step 5. 5  Otherwise, allow them to continue to cook until they are fork tender. Lay a couple more pieces of foil on top of the ribs and crunch the edges together to make a big package. Do the same with your second rack of ribs. Now for the fun part-pop them into a 275 degree oven for 3 1/2 to 4 hours. Place meat in large baking dish in about one inch of water (or halfway each rib). Bake at 250 degrees for one hour-remove from oven-turn meat. Bake at 250 degrees for one hour-remove from oven. Drain and add barbeque sauce as needed-increase heat to 400 degrees. For pork ribs that literally fall off the bone, I use an oven to slowly cook the ribs. The recipe is quite simple: mix 18 oz. of barbeque sauce (1 bottle) with 1/2 cup (120 mL) orange juice. Pour into a 9x13-in pan. Place ribs in pan and flip using tongs so ribs are coated. According to the USDA it is safe to bake (in the oven) frozen chicken. Simply add 50% of the normal time it would bake. So if you're cooking a whole chicken that is about 3 pounds, you'd normally cook it thawed for 1 hour. So frozen you'd cook it for an hour and 1/2.
