Preheat the oven to 450 degrees.
Peel and wash the beets and carrots. Slice to make the thickness even so everything cooks properly.
Add to a baking sheet and toss with olive oil, sea salt and pepper.
Bake for 20 minutes.
While the vegetables are roasting, mix melted butter and honey. Whisk so it's well combined.
After 20 minutes, remove the vegetables from the oven and drizzle with the honey butter mix. Toss with tongs so everything is well coated.
Bake for another 5 minutes and then serve with salt and pepper to taste.
