Preheat the Oven:

Preheat your oven to 275°F (135°C).

Remove Membrane:

Turn the ribs over to the bone side. Use a knife or your fingers to lift and loosen the membrane on one of the middle bones. Once loosened, grip the membrane with a paper towel and pull it off.

Prepare the Dry Rub:

In a bowl, mix the brown sugar, paprika, salt, black pepper, garlic powder, onion powder, and cayenne pepper to create the dry rub.

Season the Ribs:

Sprinkle the dry rub over both sides of the ribs and rub it in to ensure an even coating.

Wrap in Aluminum Foil:

Lay out two long pieces of heavy-duty aluminum foil (long enough to wrap each rack of ribs separately).

Place each rack of ribs on a piece of foil and wrap tightly. Make sure the foil is sealed so the juices won’t escape.

Bake in the Oven:
