Make your foil packet with your potatoes and carrots by placing your potatoes, carrots and diced onions into a piece of foil and fold the foil around the veggies making a bowl.
Add your house seasoning, 1 T of water and butter to the foil bowl
Seal the bowl by pinching the foil at the top
Set to the side
Place your water, sliced onions and a few drops of liquid smoke, if using, in the bottom of the crockpot
Place the foil packet on top of the onions.
Season your ribs with the bbq seasoning and place on top of the foil packet
Cook on High Pressure for 30 minutes then let it Natural Release or 10 minutes
Remove the ribs from the instant pot and brush with BBQ sauce
If you’d like to crisp the ribs up a little you can put them under the broiler for just a few minutes.
Remove the veggie packet
Serve and Enjoy!
