Combine the paprika, turmeric, cayenne, and salt in a small bowl and set aside.
Lightly grease 2 large baking sheets.
Wash and dry the potatoes and slice thinly with a knife, mandolin, or veggie peeler, and transfer to a large bowl.
Add the olive oil and toss to coat, start with 2 tablespoons, then add more if needed.
Sprinkle in the spice mixture and toss to evenly coat all the potatoes evenly.
Layout in a single layer on the baking sheets and bake for 7-10 minutes. Flip and return to the oven for another 7-10 minutes. At this point, I may flip a few more times and rotate the pans. Cooking time really depends on the thickness of the potatoes. Keep a close eye on them and turn the oven down if it looks like they're cooking too fast or burning. If using a mandolin, cooking time will be quicker, so check after 5 minutes.
Remove from oven and sprinkle with coarse sea salt.
Enjoy!
