Preheat the oven to 350 degrees. Line 2 baking sheets with unbleached parchment paper.
You can trim the stems off the leaves and just roast the leaves if you want. I did a mix of both. The stems become very tender, but not crispy. Place the greens in a large mixing bowl and drizzle with a little coconut oil. You only need enough to lightly coat the leaves. Rub a little coconut oil on both sides of the leaves and arrange the greens in one layer on the prepared baking sheets. Sprinkle with a little salt. Be conservative with the salt since beet greens are high in natural sodium.
Bake for 5 minutes and then turn the leaves over and bake for another 5 minutes or until dry and crispy. Oven temperatures vary wildly, so if your oven runs hot, you may want to check the greens after 3 minutes. They won’t taste good if they’re burned!
