Cut radishes in half lengthwise and place on a baking sheet. Drizzle with olive oil, season with salt and pepper, and toss to coat. Arrange in a single layer, cut side down.
Drizzle with balsamic vinegar and bake for 15-20 minutes or until radishes are caramelized and fork tender. Season with additional salt and pepper to taste.
