Cook the ribs

• Slice the ribs in half and coat them in the dry rub. 
• Place a trivet in the inner pot of the Instant Pot and add the broth, apple cider vinegar, Worcestershire sauce, and liquid smoke (if using). 
• Stack the ribs on top of the trivet. Place the lid on the Instant Pot and make sure the valve is in the sealed position. 
• Set the Instant Pot on high for 16 minutes for tender, firm ribs or 35 minutes for ribs that shred with a fork. 
• Allow the IP to do a natural pressure release for 10 minutes then manually release any remaining pressure. 

Caramelize the Sauce

In the Oven

• Set your oven to broil and place the oven rack 6 inches below the broiler unit. 
• Place the ribs on a sheet pan and coat them all over with barbecue sauce.
• Slide the ribs under the broiler and broil them for 2 to 3 minutes on each side until the sauce gets thick and caramelized.

Air Fryer 

• Coat the ribs in BBQ sauce and place them in a single layer in the air fryer. Cook at 400°F for 6 to 8 minutes or until the sauce gets thick and sticky. 

Instant Pot Air Fryer Lid

Place air fryer basket in the inner pot of the Instant Pot. Add the air fryer lid and cook at 400°F for 6 to 12 minutes or until the sauce is sticky and thick.
