Set the Instant Pot to Saute mode. Add sesame oil and let it heat up. Add the chopped garlic, ginger, onion, and scallions and saute for 3 minutes.
Then add the chopped veggies - I have used mushrooms, cabbage, and carrots here. Saute for another 2-3 minutes.
Turn off the Instant Pot, add the veggie broth, brown sugar, soy sauce, and sriracha.
Add the ramen noodles (discard the ramen seasoning). Then add the rice vinegar and give it a mix.
Seal the Instant Pot and set the pressure-cooking cycle to 3 minutes. After the cooking cycle is complete, immediately quick-release pressure and let the valve drop down.
Once the pressure has released, and the valve has dropped, add in the bok choy and give it a mix. The bok choy needs just a few minutes in the hot ramen to be cooked.
Instant Pot Ramen with Vegetables is now ready. Serve it with a garnish of chili oil and sesame seeds.
