Preheat oven to 350 degrees. To obtain meatier ribs, cut out every other bone. Season with salt and pepper.
Arrange ribs in a single layer in 9x13-inch baking pans and cover tightly with foil. Bake until very tender, about 1 hour 10 minutes. Cool slightly.
Increase oven temperature to 425 degrees. Line a baking sheet with foil and place a baking rack on the sheet.
Brush ribs generously with BBQ sauce. Bake until ribs are hot and sauce starts to glaze, about 25 minutes.
