Spray 2-3 large rimmed backing sheets with cooking spray. Place two short pieces of foil on top of the baking sheet followed by one long piece on top of the two short pieces (see photo above for wrapping reference). Remove baby back ribs from packaging. Pat dry with a paper towel, then rub with your favorite barbecue sauce on both sides. Tightly fold foil on top of ribs, folding in the ends. Then place on the baking sheet. Repeat until all the racks are slathered with barbecue sauce and packaged.
Bake for 90 minutes. Half way through the cooking time, turn the baking sheets. Remove the baby back ribs from the oven after the 90 minutes.
Brush additional sauce on the ribs and bake for an additional 30 minutes uncovered.
Flip the ribs, brush more barbecue sauce on and cook for an additional 15 minutes.
Remove the ribs from the oven, cut the ribs, and coat with additional barbecue sauce. Enjoy immediately.
Barbecue Sauce - I love Sweet Baby Ray's barbecue sauce, but you can use whatever barbecue sauce you love.
Ribs - I like to make three large slabs that equals about 8.5 pounds.
Yield - I like to serve 1 pound of ribs per person that's about ⅓ rack of ribs.
