This delicious creamy potato gratin is the kind of dish I like to make with leftover ham roast.

If the piece of ham has been frozen, thaw it and pat the ham slices dry with paper towels before using. Depending on the season and the variety of potatoes the cooking time may vary. If necessary, cook for a few more minutes, remembering to let stand 10 minutes before depressurizing.

The gratin is just as good reheated. Simply cover it with aluminum foil and reheat in the oven at 250 ° F.

A mandolin is handy for slicing potatoes.

In step 9 you can grill the gratin with the lid of an air fryer that fits the Instant Pot.

Note that the total cooking time takes into account the time that the Instant Pot takes to start cooking, cooking and the standing time before releasing pressure.

Whisk the liquid mixture again and pour into the mold, taking care to pour some on all the potatoes.
