Peel & slice 3 smaller sweet potatoes as thin as you possibility can. (Extremely thin)

A mandolin works really well for this.

I used my CleanFoodCrush.com/Spiralizer (slicing attachment)

Pour 1.5-2 cups (depending on vinegar intensity you enjoy) apple cider vinegar or white vinegar over the sliced potatoes in a medium glass bowl.

Pour room temperature water in the bowl just until potatoes are completely covered in liquid.

Soak potatoes for 1-2 hours, then DRY well(pat with paper towels). This step increases the crunchiness factor.

Preheat oven to 450 degrees f

The prepared sweet potato slices

2 Tbsp avocado oil, or extra virgin olive oil

1 tsp sea salt, or to taste

Combine & coat well. Spread potatoes onto 2 or 3 large flat sheet pans, in a single layer. They will not crisp if they are piled up. I have found that they are crispier when I use foil as a pan liner.

Roast in a preheated 450 degree oven for about 10 minutes per side (flipping once) until crispy. About 20 minutes total. Enjoy!
