A low and slow cooking method makes these oven baked ribs so tender they fall off the bone. Once baked, we like to add a sweet and spicy barbecue sauce to the ribs, but a variety of sauce options are also tasty. For teh most tender oven baked ribs, we remove the thin membrane covering the back of the rack.
If the ribs still have a thin membrane covering the backside of the rack, remove it
Season both sides of the rack with a generous amount of salt and pepper. Place the rack, meat side up, in a large roasting pan or rimmed baking sheet. It may be necessary to break the rack in half to fit in the pan.
Cover the pan or baking sheet tightly with aluminum foil and bake until the meat falls easily off the bone, approximately 3-4 hours.
Make Barbecue Sauce
While the ribs bake, make the barbecue sauce. Heat the olive oil in a saucepan over medium heat.
Add the onions and cook until soft and translucent, approximately 5-8 minutes. Stir in the cumin and cook for an additional 30 seconds.
Add the ketchup, hot chili sauce, brown sugar, and apple cider vinegar. Stir to combine, season with salt and pepper and cook for two minutes. Set aside
To Finish
Remove the ribs from the oven. Discard teh foil and generously brush both sides of the rack with the barbecue sauce.
Optional: Move an oven rack near the top of the oven. Turn broiler to high and broil the rack for 3-4 minutes, just until the barbecue sauce begins to carmelize. Keep a close eye on the ribs to avoid burnt sauce.
