Cut the pork shoulder into 5-6 equal pieces and place into the instant pot. NOTE: Don't miss this step! Cutting up the pork shoulder makes the protein super tender that's easy to shred.
Take your knife and score the fat on the pork shoulder. This will allow the fat to render down and create more tenderness.
Pour the can of diet coke.
In a mixing bowl combine 2 cups of BBQ sauce with the remaining ingredients. The maple extract is optional but it will help mimic the flavor of brown sugar.
Pour BBQ mixture over pork shoulder.
Place lid on the pressure cooker and make sure it is set for "SEALED". Set to pressure cook on high for 45 minutes. Once it is done cooking, turn the valve to the vent position and remove lid once the float valve has dropped.
Remove the pork from the Instant Pot. Let the pork rest for 10-15 minutes to "relax" the meat.
Once pork is in set aside, select the sauté setting and cook down the liquid for 15-25 minutes.
Shred pork shoulder with two forks and pour reduced sauce over the pulled pork.
Place the shredded pulled pork with the sauce in the oven under broil for about 5-10 minutes. This will create crispy ends!
Serve with a side of low carb coleslaw or a simple salad. Enjoy!
Tip: If you dont want to wait 15-25 minute for the sauce to reduce, save 1/2 cup of the BBQ sauce. Once the pork is done cooking in the instant pot, spread the 1/2 cup of BBQ sauce over the shredded pulled pork. Broil in the oven for 5-10 minutes until the pork edges are crispy and the sauce is slightly caramelized! While the pork is in the oven, saute the liquid in the instant pot until reduced (15-25 min). Freeze the sauce and save for your next batch of Instant Pot Pulled Pork!
