Herb-Crusted Salmon with Roasted Vegetables and Herby Couscous
Salmon fillets coated in a fragrant crust of fresh herbs, garlic, and lemon zest, roasted alongside a colorful medley of vegetables kissed with a subtle Asian-inspired glaze — all served over a fluffy, herb-flecked couscous that soaks up every last drop of those gorgeous juices. Fresh basil brings a beautiful sweet, peppery warmth to the herb crust and couscous, making this feel a little more Italian countryside than weeknight dinner — in the best possible way. Salmon's rich, fatty flesh pairs beautifully with the bright herby crust, making every bite feel a little indulgent.

Ingredients
- 4 (6 oz) fillets salmon fillets, skin-on, patted dry (centre-cut fillets of similar thickness will roast most evenly)
- ¾ cup, packed fresh flat-leaf parsley, roughly chopped (½ cup for the herb crust, ¼ cup for the couscous)
- ½ cup, packed fresh basil, roughly chopped (¼ cup for the herb crust, ¼ cup for the couscous)
- 5 tbsp fresh chives, roughly chopped (3 tbsp for the herb crust, 2 tbsp for the couscous)
- 2 tbsp fresh mint, roughly chopped (for the couscous)
- 5 cloves garlic, peeled
- 3 lemons lemon, zested and juiced (one for the crust, one for the couscous, one for serving)
- 6 tbsp olive oil (divided — 1 tbsp for glaze, 1 tbsp for veg, 2 tbsp for herb crust, 2 tbsp for couscous)
- 2 tbsp coconut aminos (adds a subtle umami-sweet Asian note)
- 1 tbsp rice vinegar
- 1 tsp honey
- 2 tsp fine sea salt (divided across fish, veg, herb crust, and couscous)
- ¼ tsp red chilli flakes (optional, for a little heat)
- 2 medium zucchini, cut into half-moons
- 2 large red bell pepper, deseeded and cut into chunks
- 7 oz broccolini, trimmed (regular broccoli florets work too)
- 1 cup cherry tomatoes
- 1 tbsp margarine (dotted over the fish just before roasting)
- 1½ cups couscous (regular or whole wheat both work great)
- 1½ cups vegetable or chicken stock (for cooking the couscous — water works too but stock is tastier)
- ½ tsp ground cumin (stirred into the couscous for warmth)
Instructions
- Preheat your oven to 425°F (220°C). Line a large baking sheet (or use two if needed) with parchment paper or foil.
- Make the vegetable glaze: in a small bowl, whisk together 2 tbsp coconut aminos, 1 tbsp rice vinegar, 1 tsp honey, and 1 tbsp olive oil. Set aside.
- Cut 2 medium zucchini into half-moons and 2 large red bell peppers into chunks. Trim 7 oz (200 g) broccolini. Spread all the vegetables plus 1 cup cherry tomatoes across the baking sheet(s). Drizzle with the vegetable glaze and 1 tbsp olive oil, sprinkle with ½ tsp salt, and toss well to coat. Spread into a single layer.
- Slide the vegetables into the oven and roast for 15 minutes. While they roast, you'll make the herb crust and get the couscous going.
- While the vegetables roast, make the herb crust: add ½ cup packed fresh parsley, ¼ cup packed fresh basil, 3 tbsp fresh chives, 5 peeled garlic cloves, the zest and juice of 1 lemon, 2 tbsp olive oil, and ½ tsp salt to your food processor. Pulse 8–10 times until you have a coarse, bright-green paste — chunky is great, you don't want a smooth purée.
- Now start the couscous: bring 1½ cups (360 ml) vegetable or chicken stock to a boil in a small saucepan. Stir in ½ tsp ground cumin and ¼ tsp salt. Add 1½ cups (265 g) couscous, stir once, cover tightly, and remove from the heat. Let it steam, undisturbed, for 10 minutes.
- Pat 4 (6 oz / 170 g) salmon fillets completely dry with paper towels. Season the tops lightly with ½ tsp salt. Spoon and press the herb paste generously onto the top of each fillet.
- When the 15-minute vegetable roast is done, give the vegetables a quick toss. Push them to the edges of the baking sheet to make space in the centre. Nestle the herb-crusted salmon fillets skin-side down in the middle. Dot 1 tbsp margarine in small pieces across the tops of the fillets.
- Return the pan to the oven and roast for another 10–12 minutes, until the herb crust is golden and fragrant and the salmon is just cooked through — it should flake easily when pressed with a fork and be opaque throughout, or still have a very slightly translucent centre if you prefer it medium. The internal temperature should read 125–130°F (52–54°C) for medium or 145°F (63°C) for fully cooked. Salmon cooks faster than white fish, so start checking at 10 minutes.
- While the salmon finishes roasting, fluff the couscous with a fork. Drizzle in 2 tbsp olive oil and the zest and juice of 1 lemon. Fold in ¼ cup packed fresh basil, ¼ cup packed fresh parsley, 2 tbsp fresh chives, and 2 tbsp fresh mint. Taste and adjust salt. The couscous should be light, fragrant, and bright green — basically a salad that decided to be a grain.
- Remove the salmon and veg from the oven and let everything rest for 2 minutes. Squeeze the remaining 1 lemon over the salmon and vegetables. Spoon a generous mound of herby couscous onto each plate, top with the roasted vegetables, then lay the herb-crusted salmon on top. Scatter any leftover fresh herbs over everything and serve immediately.
