What recipes have you tried?
I always slice 'em thin, to look like french fries, put a little olive oil on them, sprinkle garlic powder, mix together in a bowl. Spread them into a single layer on a cookie sheet. Oven at 425F for 15 minutes.
Always turn out yummie for me this way. I think if you flip them around mid cook, and maybe leave them in longer, you'll achieve more crispy-ness.
Stumbled into Primal due to food allergies, and subsequent elimination of non-primal foods.
