Please note that they do take a while to cook in the smoker or oven. You can reduce the cooking time by pre-baking the potatoes the day before.
I use regular potatoes and sweet potatoes. The sweet potatoes are a little chewier but still really good! Both are prepared the same basic way...
Drizzle olive oil over the slices and then add salt, pepper, mesquite rub, or whatever spices you like over the chips. Be careful not to add too much salt!
You can flip the slices over and add more spices but it usually isn't necessary.
I put these on the smoker at 250F - 300F depending on what else you are cooking. If the potatoes are pre-baked the cook time should be around 1 to 1 1/2 hours. If the potatoes are not pre-cooked then the cook time is 1 1/2 hours - 2 hours.
When done, they should be a bit crispy.
