Remove the membrane from the back of the ribs and cut them into sections if needed.

In a small bowl, mix together paprika, brown sugar, garlic powder, onion powder, salt, black pepper, and cayenne pepper.

Rub the seasoning mixture all over the ribs.

Add water to the Instant Pot and place a trivet inside.

Arrange the ribs on the trivet, standing them upright if necessary.

Close the lid and set the Instant Pot to cook on high pressure for 30 minutes.

Once cooking is complete, allow for a natural pressure release for 10 minutes, then quick release any remaining pressure.

Carefully remove the ribs from the Instant Pot and brush with barbecue sauce.

Optional: Place ribs under the broiler for 3-5 minutes to caramelize the sauce.

Serve with additional barbecue sauce on the side.
