Season ribs with salt, pepper, granulated onion powder and granulated garlic powder.
Lay ribs meat-side down on a baking sheet with an elevated edge. Add one cup of water and cover the sheet pan completely in aluminum foil.
Bake in 325-degree oven for approx. 2 1/2 hours or until meat is tender enough to be pulled from the bone.
Chill the baby back ribs in the refrigerator for about one hour so that the meat doesn't fall apart.
Apply canola oil to grill grates and heat to medium-high.
Place ribs on grill meat-side up and baste with BBQ sauce.
Grill for approx. 3 minutes.
Flip so meat-side is down, and grill for 3 minutes. Apply BBQ sauce to the back of the ribs.
Grill ribs until BBQ sauce has started to caramelize and meat has started to get crisp edges.
Let ribs rest for 5 minutes, then brush with BBQ sauce before cutting them into 1-and 2-bone pieces.
Serve with remaining BBQ sauce on the side for dipping.
You can find prepared and cut racks of ribs at your local butcher or grocery store. If you have a full rack of ribs, we suggest you cut them in half if you're cooking in an oven in your home kitchen or on a standard gas grill.
