Instant Pot Au Gratin Potatoes

Slice potatoes into 1/4-inch thick slices using a mandolin. Rinse under cold water to remove excess starch.

Turn on a multi-functional pressure cooker (such as Instant Pot). Add potatoes, chicken broth, onion, parsley, garlic powder, paprika, salt, and pepper. Close and lock the lid. Select high pressure according to manufacturer's instructions; set timer for 1 minute. Allow 10 minutes for pressure to build.

Release pressure carefully using the quick-release method according to manufacturer's instructions, about 5 minutes. Unlock and remove the lid.
