Assemble Crostini: Spread a generous layer of the browned butter on each toasted baguette slice. Top them with the thinly sliced radishes, then season with freshly cracked black pepper and a sprinkle of flaky sea salt.
Garnish: Finish each crostini with a light sprinkle of fresh thyme leaves and a squeeze of fresh lemon juice to add an extra layer of brightness before serving.
