Prep the radishes: Scrub the watermelon radishes and trim both ends. If the skin is tough, peel lightly, but keep as much color as possible.
Slice thinly: Using a mandoline or a sharp knife, slice into paper-thin rounds.
Aim for transparency—you should almost be able to see through them.
Arrange the carpaccio: Fan the slices on a large plate or platter, overlapping slightly to create a mosaic. Keep it to a single layer for best texture.
Make the dressing: In a small bowl, whisk 2 tablespoons olive oil with 1 tablespoon lemon juice, a pinch of zest, and 1/2 teaspoon honey. Season with salt and pepper to taste.
Dress lightly: Spoon or drizzle the dressing evenly over the radish slices.
You want a thin, glossy coat—not a pool.
Add the accents: Sprinkle with chopped fresh herbs. Scatter a few capers and a handful of shaved Parmesan if using. Finish with toasted nuts or seeds for crunch.
Season to finish: Add a final pinch of flaky sea salt and a twist of black pepper.
A light extra drizzle of olive oil won’t hurt.
Rest briefly: Let the plate sit for 5–10 minutes so the flavors open up and the radish softens slightly.
Serve: Bring it to the table as a starter or side. It pairs beautifully with crisp white wine, sparkling water with citrus, or a light roast chicken or fish.
