Fennel, Apple & Celery Salad with Blue Cheese & Walnuts

Fennel, Apple & Celery Salad with Blue Cheese & Walnuts

Published September 28, 2026

Crisp raw salad of shaved fennel, apple, and celery dressed with a light vinaigrette, topped with crumbled blue cheese and toasted walnuts.

Toss apple slices with lemon juice immediately after slicing to prevent oxidation and browning. Toast walnuts in a dry skillet over medium heat for 3–4 minutes, stirring frequently, until fragrant and lightly browned. Cool before adding to salad.

Assemble salad just before serving to keep fennel and celery crisp; the dressing will soften them over time. For a creamier salad, whisk a small amount of crème fraîche or Greek yogurt into the vinaigrette.
