Directions
Set your Instant Pot to the Sauté function on high.
Pour in the chicken stock and soy-free Korean stock and bring to a simmer, cooking for 2 minutes to allow the flavors to meld.
Add the thinly sliced pork to the pot. Cancel the Sauté function. Secure the lid, ensure the steam valve is set to 'Sealing,' and cook on the 'Stew/Meat' setting for 15 minutes.
Once the timer finishes, perform a quick pressure release by carefully turning the valve to 'Venting.'
Once the pin drops, open the lid and stir in the spiralized zoodles and quartered shiitake mushrooms.
Reseal the pot, set the valve to 'Sealing' again, and cook on the 'Stew/Meat' setting for 1 additional minute. This is just enough time to tender-crisp the vegetables.
Perform another quick pressure release. Carefully open the lid, ladle the pho into bowls, and enjoy immediately.
Don't have pork shoulder? Thinly sliced beef sirloin or chicken thighs are excellent substitutes.
Adjust cook time for chicken down to 10 minutes.
