Preheat the oven to 400 degrees Fahrenheit.

Wash the burdock roots thoroughly to eliminate any dirt or grit before slicing into one-inch rounds.

Toss the burdock rounds in a basin with the olive oil, salt, and pepper.

Place the roots on a sheet pan, cut sides down. Roast for 15 minutes, or until one side is browned, then turn. Return to the oven for 10 minutes more.

If preferred, serve with a splash of soy sauce and a sprinkling of sesame seeds.
