This slow-roasted arctic char with fennel salad is an elegant high-protein dish that relies on gentle temperatures to achieve a melt-in-the-mouth texture. By cooking the fish slowly in a moderate oven, the delicate oils of the char or salmon are preserved, resulting in a succulent finish that contrasts beautifully with the bright, acidic notes of the salad. The caraway seeds and preserved lemon offer a sophisticated flavour profile that elevates the fish without overpowering its natural sweetness.
Perfect for a light lunch or a nutritious evening meal, this dish is as healthy as it is vibrant. The combination of quick-pickled fennel and fresh dill provides a refreshing crunch that cuts through the richness of the fish. Prepare the pickled garlic and fennel components up to a day in advance for a quick yet impressive homemade meal that is naturally rich in essential omega-3 fatty acids.

Ingredients for Slow-Roasted Char with Fennel Salad
120ml unseasoned rice vinegar
1 tablespoon sugar
1 teaspoon caraway seeds
2 teaspoons kosher salt, plus more
6 garlic cloves, thinly sliced
1 small fennel bulb, thinly sliced on a mandoline, divided

How to make Slow-Roasted Char with Fennel Salad
Back to contentsPreheat oven to 149°C. Bring vinegar, sugar, caraway seeds, 2 teaspoons salt, and 80ml water in a small saucepan to a simmer over medium heat, stirring to dissolve sugar. Remove from heat and add garlic. Let sit until garlic is slightly softened, 10–15 minutes.
Add half of fennel and toss to coat. Let sit until fennel softens slightly and tastes pickled, 8–10 minutes.
Meanwhile, place char in a 2- or 3-qt. baking dish and coat with 1 tablespoon oil; season with salt and pepper. Roast until flesh easily flakes apart and a paring knife inserted into fish meets no resistance, 15–18 minutes.
Drain fennel mixture; discard liquid. Toss in a small bowl with lemon juice, preserved lemon, remaining 3 tablespoons oil, and remaining fennel; season with salt and pepper. Mix in dill.
Serve char topped with fennel salad.
Garlic and fennel can be pickled 1 day ahead. Cover and chill.
