For an overview of InstaMash in the Fallout series of games, see InstaMash.


InstaMash and preserved InstaMash are consumable items in Fallout 4.


InstaMash comes in a rectangular box, with what appears to be an electrical unit on the rear and its beaters on the bottom of the box. As the name suggests this is most likely a potato-based food product.

Although it heals 20 HP, there is also a cost of 7 rads added to the Sole Survivor's rad meter. As such consumption in large quantities, without taking precautions, could prove fatal.

Preserved InstaMash can be found rarely in the Commonwealth but can be manufactured in the food processor. Consuming preserved InstaMash will heal for 45 HP without a rad penalty.
