Prepare Radishes: Start by placing your rinsed and trimmed radishes in a medium saucepan. Cover them with water and boil for about 20 minutes, or until they are fork-tender.

Preheat Oven: While the radishes are boiling, preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.

Drain Radishes: Once tender, drain the radishes in a colander and let them rest for about 5-10 minutes.

Make Butter Mixture: In a small saucepan, melt the unsalted butter over low heat. Add the minced garlic, chopped fresh rosemary, and a sprinkle of sea salt.

Smash and Season: Transfer the radishes onto the lined baking sheet. Using a fork, gently smash each radish and drizzle the butter mixture over them.

Roast: Place the baking sheet in the preheated oven and roast the radishes for about 25-30 minutes, until golden brown.

Enjoy warm! Garnish with additional fresh rosemary before serving.
