Ensure the radishes are washed, trimmed, and sliced in half for even cooking.
In a skillet over low heat, melt the butter until it begins to shimmer. Arrange the halved radishes cut-side down in the pan, allowing them to develop a rich, golden-brown sear. Sprinkle with salt and freshly ground black pepper, adjusting to taste.
Stir occasionally, ensuring all sides of the radishes soften and caramelize evenly. Continue cooking for about 10 minutes or until they reach a tender yet slightly crisp texture.
Transfer the sautéed radishes to a serving dish and enjoy them hot as a flavorful side dish or a unique addition to any meal.
