Start by washing the radishes thoroughly under cold water. Trim the tops and roots, then cut them in halves or quarters depending on their size. Set aside.
Heat your skillet over medium heat until it’s shimmering, then add the butter. Let it melt and foam gently for about a minute until it develops a nutty aroma and turns a light golden color.
Add the radishes to the skillet in a single layer. Sauté for about 3-4 minutes, stirring occasionally, until they start to turn golden on the edges and release a fragrant aroma.
Reduce the heat to medium-low and continue cooking, stirring every minute, for another 5-7 minutes. You'll notice the radishes soften, and their edges become more caramelized and tender.
Check the tenderness by piercing one with a fork; it should slide in easily. The radishes should look soft and glossy, with a light caramel hue on their edges.
Squeeze the lemon juice over the radishes and give everything a gentle toss. This brightens the dish and balances the richness of the butter.
Remove the skillet from heat. Transfer the radishes to a serving dish, drizzle with any remaining buttery juices, and sprinkle with flaky sea salt for added flavor and crunch.
Serve the sautéed radishes hot or warm as a comforting vegetable side, enjoying their tender texture and sweet, nutty flavor.
