Preheat your oven to 200°C (400°F). Line a baking sheet with parchment paper, ready for the radishes.
Wash the radishes thoroughly, then trim off the tops and roots. Cut the smaller radishes in half, and quarter larger ones so they cook evenly and look uniform.
In a small bowl, mix the minced garlic with the olive oil, a pinch of salt, and freshly cracked black pepper. Stir until well combined and fragrant.
Toss the prepared radishes in the garlic oil mixture, ensuring each piece is generously coated with the fragrant oil.
Spread the coated radishes evenly on the prepared baking sheet, making sure they are in a single layer with space around each piece for crispy edges.
Place the baking sheet in the oven and roast for about 20-25 minutes. Halfway through, flip the radishes to promote even caramelization and smoky edges.
Keep an eye on the radishes as they roast; they should turn deep golden amber around the edges and become tender when pierced with a fork.
Remove the radishes from the oven and let them rest for a couple of minutes. Drizzle with a little extra olive oil if desired, and sprinkle with additional salt or herbs for extra flavor.
Serve these smoky, tender radishes warm as a side dish that surprises with their rich, caramelized flavor and soft, melt-in-your-mouth texture.
