Turn your oven to 425 and grease or line a rimmed baking sheet with parchment paper. One of these split sheets is also a super helpful and reusable kitchen tool.
Peel kohlrabi: cut off a disc from the top and the bottom, and then like a melon, all the way around.
Slice the kohlrabi bulbs into home-fries.
Toss with the melted oil and sprinkle on some sea salt and cover generously in your spice blend (use your favorites to change it up! An Indian spice blend, a chipotle or Mexican blend, or just some store bought chili powder.)
Roast for 30 minutes, tossing halfway and rotating the pan. Serve right away with a dipping sauce.
