Add the broth, cream, garlic, salt, pepper and noodles to the Instant Pot in that order. Do not stir, but make sure all noodles are covered. You can move things around a bit, but don't stir.
Lay the frozen chicken tenderloins on top of the pasta.
Set your Instant Pot to Manual high pressure for 6 minutes. Allow for a 6 minute natural pressure release before turning the knob to quickly release the pressure.
Remove the chicken. Let it rest while we finish the sauce.
Slowly add in the parmesan cheese and twirl the noodles with some tongs. The cheese will thicken the sauce.
Once the cheese has been added and the sauce has thickened, dice the chicken and add back into the pot.
It is ready to eat, enjoy!!
