  • 750 g new potatoes/baby potatoes/Jersey Royals scrubbed, unpeeled, halved or quartered if large
  • 4 salmon fillets (skin on) see notes
  • 2-3 spring onions finely sliced
  • 1 teaspoon (heaped) dried thyme or leaves taken off few sprigs of fresh thyme see notes
  • 1 lemon
  • 2 tablespoon rapeseed or olive oil
  • salt, pepper


  • Preheat the oven to 180C/350F/Gas mark 4. 
  • Scrub your potatoes but leave them unpeeled. Halve or quarter bigger ones and leave the really small ones whole trying to keep them similar size so that they roast evenly. 
  • Put them in the roasting tray with olive oil, thyme and good amount of salt and pepper. Give them a mix with your hands making sure they are evenly covered with oil and seasoning and put into preheated oven for 20 min. 
  • After 20 minutes take the roasting tray with the potatoes out of the oven and give the potatoes a little shake (you might need to use spatula if they got a bit stuck to the bottom) and put your salmon fillets on top (skin down). 
  • Sprinkle the fillets with juice squeezed out of half a lemon , season with some salt and pepper and put back in the oven for 13-15 min or until salmon fillets are cooked  (the timing will depend on the thickness of your fillets). The fish should be just opaque.  
  • Take baking tray out of the oven and sprinkle salmon and potatoes with some spring onions.
  • Serve with sides of your choice and extra lemon wedges.


  • Nutritional information is approximate and per serving (without any sides) and should be treated as a guideline only. 
  • Feel free to substitute thyme with rosemary or simply use both.
  • If using frozen salmon fillets, make sure they are defrosted first.
