Rub pork roast with garlic powder, onion powder, seasoned salt, and pepper. Place roast in Instant Pot.
Pour Dr. Pepper and your favorite BBQ sauce on top of roast.
Place lid on the Instant Pot and lock in place. Set the knob to sealing, not venting.
Push the Manual button and set for 60 minutes. If your roast is bigger, cook it for longer.
(For example if you have a 5 pound roast, you will need to cook it for 90 minutes.)
Notes
To turn this recipe into a freezer meal, follow the following steps:
Place leftover pork, garlic powder, onion powder, seasoned salt, black pepper, chili powder, Dr. Pepper, and BBQ sauce into a gallon-sized freezer bag. Place freezer bag into freezer and it will last up to 60 days.
When ready to use, dump ingredients from bag into Instant Pot and add 1/2 cup of beef broth or little water in with the frozen food.
Place the lid on top, move the valve to SEALING, and press the MANUAL button. Set timer for 90-100 minutes (or about 30 minutes per pound of your roast).
Do a NATURAL RELEASE when the timer is done – I even like to let it sit in the Instant Pot for a few hours so that it falls apart so easily. Follow the rest of the instructions as written.
