  • 2 salmon fillet, about 140g/5oz each
  • 2 tsp wholegrain mustard
  • squeeze lemon juice
  • 1 small celeriac, about 350g/12oz, peeled and cubed



    The unsung hero of the vegetable world, knobbly, odd-shaped celeriac has a subtle, celery-like…

  • 1 floury potato, peeled and cubed



    The world's favourite root vegetable, the potato comes in innumerable varieties. A member of…

  • 140g frozen pea


  1. Line a grill pan with foil and lightly brush with oil to stop the salmon sticking. Add the salmon and spread each fillet with 1 tsp mustard. Curl up the edges of the foil to catch any juices, then squeeze over a little lemon juice. Heat the grill to medium.

  2. Boil the celeriac and potato for 15 mins. Add the peas, then cook for a further 5 mins until the vegetables are tender. Meanwhile, grill the salmon for 12-15 mins.

  3. Drain the vegetables, reserving a cup of the cooking water, then mash roughly so that the peas start to break up. Add a little of the cooking water to loosen the mix, if you like. Season to taste, then divide between two warm plates and top with the salmon. Pour over any pan juices, then serve.

I was not convinced about the taste of the pea & celeriac mash. But overall a fine dish

Just Great

Instead of the cooking water I use half fat creme fraiche - makes the mash beautifully creamy.

As it was my wedding anniversary today I wanted something quick and simple. I also put the salmon in a hot oven for 15 minutes and it came out perfectly cooked and tasted delicious.

This was a quick midweek dinner. Instead of grilling the salmon, I put it in a hot oven for 15 minutes and it came out cooked perfectly. Mashing the celeriac with the potato gave a pleasant taste - not too strong. Would make again.

Combination of the mustard salmon and vegetables is lovely. Great way to prepare celeriac.

Very easy, very tasty. We had organic, boneless, skinless chicken thighs in the fridge, so substituted for the salmon. Grilled under medium heat for 20 mins. (10 mins. per side)
