Cold Roast Salmon with Smashed Green Bean Salad

This cold roast salmon with smashed green bean salad is a sophisticated yet simple heart-healthy dish, perfect for relaxed summer entertaining or a nutritious weekend lunch. The salmon is slow-roasted at a gentle temperature to ensure a buttery, melt-in-the-mouth texture that contrasts beautifully with the crunch of the vegetables. By smashing the green beans, you allow the zesty lemon dressing to penetrate deeply, creating an incredibly vibrant and savoury side dish.

Packed with omega-3 fatty acids and fresh seasonal produce, this recipe is as nourishing as it is flavourful. The addition of toasted pistachios and crisp radishes provides a wonderful variety of textures, making it a satisfying standalone meal or a stunning centrepiece for a buffet. It is also highly practical, as both the salmon and the marinated beans can be prepared a day in advance, allowing you to simply assemble and serve when your guests arrival.

How to make Cold Roast Salmon with Smashed Green Bean Salad

Preheat oven to 149°C. Place salmon on a rimmed baking sheet and rub 2 tablespoons oil over each side. Season all over with black pepper, 2 teaspoons kosher salt, and 1/4 teaspoons red pepper flakes. Arrange skin side down and roast until a tester, metal skewer, or thin-bladed knife inserted laterally through salmon flesh meets no resistance, 20–25 minutes. (Fish should be opaque throughout and just able to flake.) Let cool.

While salmon is roasting, make the salad. Whisk lemon juice, 3 tablespoons oil, 2 teaspoons kosher salt, and remaining 1/4 teaspoons red pepper flakes in a large bowl to combine. Set dressing aside.

Working in batches, place green beans in a large resealable plastic bag. Seal bag and whack beans with a rolling pin to split the skins and soften the insides without completely pulverizing the flesh. Place in bowl with reserved dressing. Toss, massaging with your hands to break beans down further and coat. Let sit at room temperature at least 1 hour.

Thinly slice radishes lengthwise. Place in a large bowl of ice water, cover, and chill until ready to serve (this will allow you to get the prep out of the way and keep the radishes crisp and firm).

Just before serving, drain radishes and toss with marinated green beans. Add pistachios; taste salad and season with pepper if needed. Transfer to a platter and drizzle with oil and sprinkle with sea salt.

Using 2 spatulas, carefully transfer salmon to another platter, leaving skin behind on baking sheet. Drizzle with oil and squeeze juice from a lemon wedge or two over; sprinkle with sea salt. Serve with more lemon wedges and Lemony Yoghurt Sauce and/or Grilled Serrano Salsa Verde alongside.

Salmon can be roasted and green beans can be marinated 1 day ahead; cover and chill separately. About 45 minutes before serving, remove green beans from the fridge and let sit at room temperature to warm up a bit. Radishes can be sliced 1 day ahead; keep chilled.
