It's hard to imagine an easier meal than this Instant Pot version of the takeout classic. Just mix the sauce in the cooker, then layer the noodles and frozen vegetables as directed in and onto the sauce. The machine doesn't really even come up to high pressure. When the float valve or pin rises to lock the lid onto the pot, turn it off and set it aside. Don't leave the pot unattended while it's coming to pressure. Pay attention to the cues in the instructions below.

Soy sauce provides the primary savory backbone of this dish, balancing the sharp acidity of unseasoned rice vinegar and the thick sweetness of hoisin. Because soy sauce brands vary wildly in sodium content, opting for a reduced-sodium variety prevents the liquid from concentrating too aggressively as the cooker heats. Rice vermicelli absorbs liquid rapidly compared to standard wheat pasta, meaning that any deviation in the three-cup broth ratio will drastically alter the final hydration level of the noodles.
Fresh ginger and garlic release sulfur compounds and aromatic oils into the braising liquid almost instantly upon contact with heat. Substituting garlic powder requires a conservative ratio of one-quarter teaspoon per fresh clove, though powdered aromatics lack the bright enzymatic bite that fresh minced roots contribute. When frozen stir-fry vegetables go into the cooker frozen solid rather than thawed, they release their moisture gradually into the sauce base instead of becoming waterlogged beforehand. Maintaining strict control over the two-minute natural release window prevents the delicate rice noodles from turning pasty against the residual bottom heat of the stainless steel insert.
