1. In a medium saucepan, add the radishes and enough water to cover them by one inch. Bring to a boil, then cover, reduce to a simmer, and cook for 20-minutes, until fork tender.
2. Meanwhile, preheat your oven to 400 degrees. Line a large baking sheet with parchment paper and set it aside.
3. Drain the radishes and allow them to rest for 5-10 minutes in a colander over the sink.
