Plug in your pressure cooker and add the avocado oil. Press the Sauté button and wait a minute or two for it to heat up. Add the red onion and sauté, stirring occasionally, for 3 minutes.

Unwrap the pork shoulder from the netting (if applicable) and lay it out on a cutting board (it will likely be folded over on itself or contain multiple pieces, so lay it all out). Sprinkle all sides with sea salt, ground cumin, paprika, garlic powder, and black pepper.

Move the onions off to one side of the Instant Pot and place the pork shoulder in the IP. Allow it to brown 3 to 5 minutes, until it has a nice crisp on it. Flip the roast over and brown on the other side another 3 to 5 minutes.

Add the remaining ingredients to the Instant Pot. Secure the lid and select “Manual.” Make sure it’s set on the high pressure setting and adjust the time for 1 hour and 20 minutes. Leaving the steam valve closed, allow the Instant Pot to do its thing. Once the time is up, allow it to naturally release for at least 20 minutes (up to 1 hour).

Remove the lid, and transfer the roast to a cutting board. Use two forks to shred the meat (it should fall apart very easily! I often just use tongs to shred the pork).

Transfer the shredded pork back to the Instant Pot and allow it to sit in the juices until ready to serve.

Note: If you’d like crispy shredded pork carnitas, heat a skillet over medium-high heat on your stove top and add a thin layer of shredded pork. Pan fry it, stirring occasionally, until the pork becomes crispy and golden-brown.

Use pineapple shredded pork for tacos, burritos, burrito bowls, or serve as-is with side dishes.
