Dinner Salad with Radicchio and Roasted Sweet Potatoes

This roasted sweet potato and radicchio salad is a masterclass in balancing bold flavours and satisfying textures. The natural sweetness of the roasted tubers provides a perfect foil for the pleasantly bitter radicchio and crisp fennel, while a creamy cashew dressing adds a luxurious, savoury depth. It is a vibrant vegetarian dish that feels indulgent yet remains incredibly nourishing, making it ideal for a light midweek supper or an impressive weekend lunch.

While the elements may seem sophisticated, this salad is remarkably simple to assemble. The contrast between the warm, caramelised potatoes and the cool, zesty dressing ensures every bite is interesting. This recipe is particularly well-suited for those looking for a heartier plant-forward meal that provides plenty of protein through the addition of jammy boiled eggs and roasted nuts.

Ingredients for Dinner Salad with Radicchio and Roasted Sweet Potatoes

  • 120ml salted, roasted cashews

  • 60ml vegetable oil

  • 3 tablespoons unseasoned rice vinegar

  • 3/4 teaspoons crushed red pepper flakes

  • 3/4 teaspoons fish sauce

  • 3/4 teaspoons honey

  • 1 garlic clove

  • Kosher salt

  • 4 small sweet potatoes (about 675g total), scrubbed, halved lengthwise

  • 2 tablespoons extra-virgin olive oil

  • 4 large eggs

  • 2 heads of radicchio (about 450g total), quartered, cores removed, leaves separated

  • 1 small fennel bulb, quartered lengthwise, thinly sliced lengthwise

  • 2 tablespoons unseasoned rice vinegar

  • 1/2 cup crushed salted, roasted cashews

  • 1/2 cup coriander leaves with tender stems

  • Kosher salt

Blend cashews, oil, vinegar, red pepper flakes, fish sauce, honey, garlic, and 80ml warm water in a blender until very creamy, smooth, and pourable. Taste dressing and season with salt.

Do Ahead: Dressing can be made 3 days ahead. Cover and chill.

Place a rack in middle of oven; preheat to 218°C. Place sweet potatoes on a rimmed baking sheet, drizzle with oil, and season with kosher salt; turn to coat. Arrange cut side down; roast until tender and cut sides are browned, 20–25 minutes. Let cool.

Bring a medium pot of water to a boil. Carefully lower eggs into water and cook 8 minutes. Transfer eggs to a bowl of ice water and let cool. Remove eggs from ice water, pat dry, and peel.

Toss radicchio, fennel, and vinegar in a large bowl; season with sea salt. Drizzle 120ml dressing down sides of bowl. Using your hands, fold salad, working from the bottom out toward the sides of the bowl, until evenly coated in dressing.

Transfer salad to a platter. Tear sweet potatoes and eggs into 1 1/2" pieces and nestle into salad. Season egg yolks with sea salt. Drizzle more dressing over and top with cashews and coriander. Serve with remaining dressing alongside.
