Katie Lee Biegel makes fall-off-the-bone tender Kansas City-style barbecue ribs in the oven.
For the barbecue sauce:
Heat the butter in a medium saucepan over medium heat. Sauté the onions until translucent, 7 to 8 minutes. Stir in remaining ingredients. Bring to a low boil, reduce the heat to low and simmer, stirring occasionally, until reduced and thickened, about 45 minutes.
For the ribs:
1. In a small bowl, combine the chili powder, brown sugar, salt, celery seed, garlic powder, onion powder, dry mustard, smoked paprika and black pepper.
2. Place each rack of ribs on a large piece of heavy-duty aluminum foil. Season each side generously with the spice mixture. Wrap the ribs tightly in foil and place on a baking sheet.
3. Bake at 500 F for 20 minutes, then reduce heat to 250 F. Bake for 2½ hours, until tender. Unwrap ribs and baste with a few tablespoons of barbecue sauce.
4. Grill or broil ribs a few minutes on each side until browned and crispy. Cut ribs and toss with additional sauce in a bowl.
