  • 2 salmon fillets, about 100g/4oz each
  • 700g celeriac, peeled to remove all the knobbly skin and cut into chunks like potato



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

  • 2 tsp wholegrain mustard



    A condiment made by mixing the ground seeds of the mustard plant with a combination of…

  • 2 tsp lemon juice
  • 100g baby spinach leaves



    Used in almost every cuisine across the world, spinach is an enormously popular green vegetable…


  1. Brush the salmon lightly with olive oil, and season with salt and pepper. Line a grill pan with foil and lay the salmon on top.

  2. Place the celeriac in a pan with cold water to cover. Salt and bring to the boil. Lower the heat, cover and simmer for 12-15 minutes until tender. Preheat the grill to medium. Whisk together the mustard, lemon juice, a pinch of sugar, salt, pepper and 1 tbsp olive oil.

  3. Grill the salmon for five minutes on each side. Meanwhile, drain the celeriac, reserving 1 tbsp cooking water. Return the celeriac to the pan. Mash until fairly smooth. Add the spinach, stirring occasionally over a low heat, until wilted. Stir in 1 tbsp mustard dressing and the reserved cooking water. Season.

  4. Spoon the mash on to two warm plates and top each with a fillet. Drizzle over the leftover dressing.

The calorie count is all wrong on this; 100g Salmon 147c, 350g celeriac 134.40c, 100g Spinach 7g, 1 teaspoon olive oil (not even tablespoon as suggested) 40 calories = 328c = not suitable for a fast day meal on the 5:2

This is just brilliant! Really easy and VERY tasty - definitely one of the top salmon recipes! A couple of tweaks: Double-up the quantities of the mustard mix, and don't use any cooking water when mashing the celeriac.

Really delicious. We love celeriac anyway, but the addition of the spinach and mustardy dressing take it to another level. Half potato/half celeriac also works really well, if you need to double the recipe to serve four.

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

Absolutely lovely. The celeriac made a fantastic change and the mustard dressing complemented both the celeriac and the salmon fabulously. I'll certainly be making this again.

This is an excellent dish. I've made it several times now, so simple and so delicious. The celeriac ends up tasting quite creamy in spite of there being no cream in it and the wholegrain mustard really complements its delicate flavor. Makes for a really filling and quite posh meal, and very low on carbs and calories. Super.

I did not have salmon so used beef casserole instead and added a little creme fraiche to the celeriac mash. Delicious. It is a nice way of eating spinach which I only stirred in for a couple of minutes rather than wilting it.

very easy to prepare! I think celeriac is an acquired taste but nevertheless interesting! Mustard dressing really complimented the dish!

Was cooking salmon and thinking of sides, trying to utilise whatever was in the fridge. Had 1 celeriac and some spring greens so went with it. Added spring greens 5 min before taking celeriac off the hob.... there was handful of peas as well. Super tasty - my mega fussy bf who is on low carbon has asked me to make it again and again. . !
