Preheat the oven to 400 degrees. Spread your diced beets onto a rimmed baking sheet. Drizzle with coconut oil and toss to evenly coat all the beets. Add the salt and toss again to coat with the salt.
Roast in the preheated oven 35-45 minutes, until the beets are soft, slightly caramelized, and starting to get crispy. Cook them shorter for soft and not crispy, longer if you like the crispy edges. Be careful not to burn, them, though. Enjoy!
