For the marinade
For the accompaniments
Start by mixing all marinade ingredients in a bowl before pouring 2/3 over the salmon, covering and setting aside in the fridge for 1-24 hours. Keep the remaining marinade aside to serve.
Onto the roasts – pre-heat the oven to 220ºC/200ºC fan/gas 7. Tip the potato cubes into a large pan of cold water, bring to the boil over a high heat, then immediately drain and leave to steam-dry for a few minutes in a colander.
Lay onto a baking tray, drizzle with 1tbsp olive oil, dried mixed herbs, pinch of cracked black pepper and salt and use your hands to mix so evenly coated before spreading into a single layer. Place in the oven for 30 minutes ensuring to flip half-way through.
Meanwhile, lay brussels and shallots on a baking tray, drizzle with a tbsp of olive oil and season with a pinch of salt and pepper. When the potatoes have 20 minutes left, place in the oven to roast.
When your accomps have 15 mins left, place your marinated salmon on a lined baking tray and place in the oven for 12-15 mins until cooked through.
Meanwhile, mix a tbsp of olive oil with a tbsp of honey, add to a pan over a medium heat, add the walnuts and fry for 3-5 mins until evenly coated, sticky and starting to colour. Remove all veg accomps from the oven.
To serve, split the shallots, brussels and potatoes across two plates, top each with a salmon fillet followed by a scatter of walnuts, sprinkle of fresh parsley and a dollop of crème fraîche. Pour any remaining salmon marinade over the salmon and serve.
