In a 6-quart Instant Pot, press the sauté button set to“normal” or “medium”. Add oil and once the oil is hot, add the onion, garlic, and ginger and saute until browned, about 5 minutes. Stir in the spices for about 1minute to toast them.
Add the water, chicken, soy sauce, fish sauce, and salt. Scrape up any bits that are stuck to the bottom of the pot. Lock the lid in place and set the vent to “sealing”. Select “manual pressure” (set to high) and set the timer for 12 minutes
Once the timer goes off, let it naturally release for 10minutes, then manually release the pressure. Remove the lid and transfer the chicken pieces to a cutting board and shred up the meat. Set a fine mesh strainer over a large heat-proof bowl (it helps if the bowl has a pour spout) and pour the broth through the strainer to strain out the solids. Taste the broth and add more salt, soy sauce, or fish sauce if needed
Into each soup bowl, add your cooked noodles, shredded chicken, and any veggies (if using). Pour about 2 cups of broth over top. Top with bean sprouts (infusing), lots of herbs, and squeeze of lime. To increase the spice, you can stir in some sriracha or other spicy chili paste.
