Remove the membrane from the back of the ribs if it hasn't been done already. Pat the ribs dry with paper towels.
In a small bowl, mix together the salt, black pepper, paprika, garlic powder, onion powder, and cayenne pepper. Rub this seasoning mixture evenly over both sides of the ribs.
Place the ribs in a large baking dish and cover tightly with aluminum foil. Bake in the preheated oven for 2 hours, or until the ribs are tender.
Preheat your grill or oven broiler to medium-high heat. Brush the ribs generously with BBQ sauce.
Grill or broil the ribs for 5-10 minutes, basting with more BBQ sauce as needed, until the sauce is caramelized and slightly charred.
Remove the ribs from the heat, let them rest for a few minutes, then slice and serve. Enjoy!
Notes
These Party Ribs pair well with classic sides like coleslaw, baked beans, or cornbread. Adjust the cayenne pepper for a milder or spicier kick. Leftovers can be reheated in the oven or on the grill.
