Using either a peeler, a very good knife or a mandolin, slice your beetroot into very thin pieces. The thinner the better with this recipe!
Toss all of the beet slices in 1/2 tablespoon of salt, then place all of the slices on a spread of paper towels. Let them sit for 15-20 minutes to release moisture, this should soak into the paper towels.
Start preheating your oven to 300°F.
After the draining time is up, lightly pat the beets with a paper towel just to make sure they are as dry as possible.
Coat your sheet pan in a thin coating of olive oil, then add the beets. You don't want to crowd the pan, but no need to have every single beet be completely flat and not touching, you just kind of want them spread out in an even layer.
Coat with the remaining salt and pepper.
Roast the beets at 300°F for 45 minutes, then check. If they still need more time to crisp, bake for another 15 minutes.
Use a spatula to release them off the pan and dig in!
