Step 1

Make sure the stainless steel insert is in your Instant Pot.

Step 2

In a small bowl, mix the rub ingredients. Rub all over the pork roast. Cut the meat into 4 pieces.

Step 3

Press "saute" setting on your Instant Pot. Wait 2 minutes, then add olive oil. Place meat in the Instant Pot. Let it sear on each side for 2 to 3 minutes. Remove onto a plate.

Step 4

Add 1/4 cup of water and deglaze the bottom of the pot (with a wooden spoon, scrape any cooked on bits). Add remaining water and apple cider vinegar.

Step 5

Place pork back in the IP. Sprinkle chopped onion around and between the meat pieces.

Step 6

Pour BBQ sauce over the meat, do not stir.

Step 7

Close the lid, set the valve to "sealing" position. Make sure the IP is set to cook on HIGH pressure. Press "manual" setting, set timer to 45 minutes.

Step 8

The IP will take 12 to 14 minutes to come to pressure. Once the timer is done, press "cancel/off" button and do not touch the valve. Let the IP release the pressure naturally. If you quickly release it, the meat will be tough.

Step 9

Carefully open the lid away from your face. Remove the meat onto a plate and shred with two forks.

Step 10

Reserve 1/2 cup of the liquid from the IP, discard the rest. Pour the sauce over pork just before serving.
