Preheat oven to 400 degrees Fahrenheit. Line a baking sheet with Gefen Parchment Paper.

Fill a medium pot of water and bring to a boil. Cook radishes 15–20 minutes. Drain. (Alternatively, to best retain their vivid color, blanch the radishes by boiling for just two to three minutes and then plunging in ice water for two to three minutes. Then proceed to the next step.)

Place radishes on the prepared baking sheet and smash them with the bottom of a glass or a fork. (If you blanched them, they will only smash slightly.)

In a small bowl, whisk together oil, garlic, parsley, salt, and pepper. Brush over radishes.

Bake 30 minutes, flip, and bake another 10–15 minutes, until golden brown.
