In an electric pressure cooker, combine onion, garlic, shallots, ginger, chicken broth and chicken breasts. Salt generously. Secure lid, place vent to “airtight” and cook on High Pressure for 15 minutes.
Meanwhile, boil noodles according to package directions.
Once cooking cycle on chicken is complete, allow to depressurize naturally. Stir in noodles.
Serve with toppings and invite guests to make their own ramen bowls.
