Preheat oven to 375F. Thoroughly clean sunchokes - the skin is edible so no need to peel, but they are roots so you want to clean off any dirt. 1
Use a mandolin to make the sunchokes into thin even slices. Alternatively, use a knife to slice off one side lengthwise to make a flat surface (as pictured), then cut into slices.
Un mixing bowl, toss sunchokes in a drizzle of vegetable oil.
Optionally add any seasonings of choice
Line baking tray with mat / parchment paper, then line up the sunchoke slices and sprinkle salt over.
Place tray on middle rack of oven and set a timer for 10 min. After 10 min, check and remove any that're done – look for ones that have started showing some golden, light brown.
Put the rest back in the oven, and set a repeat timer to check every 2 min to remove ones that're done. 2
Let cool on a plate until crunchy. Store in airtight container (I like to store with that little silica packet that's in vitamin bottles to absorb moisture). Or, eat em' all
