Preheat your oven to 250°F.

Place the frozen pulled pork in a baking dish and add a splash of water or broth to it.

Cover the dish with foil and place it in the preheated oven.

Cook for 20-25 minutes or until the internal temperature of the pork reaches 165°F.

Check the temperature with a meat thermometer.

Place the frozen pulled pork in the Instant Pot and add 1 cup of water or broth.

Close the Instant Pot lid and turn the pressure valve to the "sealing" position.

Set the Instant Pot to the "Manual" or "Pressure Cook" function, and adjust the time to 20 minutes.

Once the cooking time is up, allow the Instant Pot to naturally release pressure for 10-15 minutes.

Carefully open the Instant Pot lid and use a meat thermometer to check the internal temperature of the pulled pork. It should be at least 165°F to be safe to eat.

If the pulled pork is not heated through or at the right temperature, continue cooking for another 5-10 minutes.

Place the frozen pulled pork in a microwave-safe dish and cover it with a damp paper towel.

Microwave on high for 3-4 minutes, depending on the amount, or until the internal temperature of the pork reaches 165°F.

Check the temperature with a meat thermometer.

Stir the pork halfway through the cooking time to ensure even heating.

Place the frozen pork in a saucepan.

Add a cup of water or broth.

Cover and cook over low heat, stirring occasionally, until the pulled pork is heated through.
