Gently rub into ribs and let rest so that flavors work into meat at least 1 hour (this can also be done one day before cooking)
Heat oven to 325
In a ½ inch to 1 inch deep baking sheet, add onion, garlic and enough water to cover the bottom of the sheet. Place a baking rack on top of the baking sheet and add the ribs to the rack
Loosely cover ribs with foil and bake for 90 minutes covered
Remove ribs from oven and remove foil cover. Brush barbecue sauce over the ribs and place back in the oven for another 90 minutes, uncovered
When the ribs easily twist off the rack, raise oven rack and broil for five minutes
Enjoy right away!
