Place ribs in a large pot and cover with water. Stir in kosher salt, garlic powder, and pepper, and bring water to a boil over medium heat. Continue to boil until ribs are tender, 40 to 45 minutes.
While the ribs are boiling, preheat the oven to 325 degrees F (165 degrees C).
Remove ribs from the pot, and place them in a 9x13-inch baking dish. Pour barbeque sauce over ribs. Cover the baking dish with aluminum foil.
Bake in the preheated oven until the internal temperature of the pork has reached 160 degrees F (70 degrees C), 1 to 1 1/2 hours.
