Gammon Steak with Parsley Sauce and Mash

A classic British-style plate of gammon steak, parsley sauce and mash brings together salty cured pork, buttery potatoes and a gentle herb sauce in a straightforward dinner. Gammon steaks cook quickly in a frying pan, developing a golden surface while staying tender and savoury. The parsley sauce is a simple white sauce enriched with butter and whole milk, then finished with fresh parsley for a clean, green note that cuts through the richness. Creamy mash makes the dish filling and familiar, while black pepper and a little lemon sharpen the finish without overwhelming the comforting flavours.

Why this recipe works

  • Classic comfort: Cured gammon, buttery mash and parsley sauce deliver the familiar savoury richness of a traditional British supper.
  • Balanced richness: Lemon brightens the creamy sauce and helps offset the saltiness of the gammon.
  • Ready quickly: The potatoes, sauce and gammon can be cooked in parallel, keeping the full meal within a short weeknight timeframe.
  • Creamy finish: A simple white sauce and well-drained mashed potatoes give the plate a smooth, comforting texture.

Ingredient notes

  • Choosing the gammon: Look for evenly cut gammon steaks so they cook at the same rate and brown without drying out.
  • Use fresh parsley: Fresh parsley gives the sauce a cleaner, brighter flavour than dried parsley, which can taste muted in a milk-based sauce.
  • Add lemon to taste: Start with a small squeeze and adjust at the end; the aim is brightness, not a sharp citrus sauce.

Texture tips

  • For smoother mash: Let the drained potatoes steam-dry briefly in the hot pan before mashing so excess water does not loosen the texture.
  • Keep the sauce silky: Whisk the milk in gradually and keep the heat moderate so the parsley sauce thickens evenly.

Common mistakes

  • Do not overcook the gammon: Gammon steaks are already cured, so they only need to be browned and heated through; extended cooking can make them tough.
  • Avoid a thick, pasty sauce: If the parsley sauce tightens too much, loosen it gradually with a little extra milk while whisking.

Make-ahead tips

  • Reheat gently: Warm leftover mash and sauce slowly with a splash of milk, stirring often, and heat the gammon separately until piping hot.
  • Best served freshly cooked: The gammon has the best texture straight from the pan, while the sauce is smoothest when served soon after making.

  1. Peel the potatoes and cut into even chunks. Put them in a large pot, cover with cold water, bring to the boil, then simmer for 12 to 15 minutes until very tender.
  2. Meanwhile, finely chop the parsley and cut the lemon in half. Pat the gammon steaks dry and season both sides with a little of the black pepper.
  3. Heat a large frying pan over medium-high heat and add 10 g of the butter. Pan-fry the gammon for 2 to 3 minutes per side until golden and heated through, then transfer to a warm plate to rest.
  4. In a saucepan over medium heat, melt 30 g of the butter. Stir in the flour and cook for 1 minute, then gradually whisk in 300 ml of the milk until smooth.
  5. Simmer the sauce for 2 to 3 minutes, whisking, until thick enough to coat the back of a spoon. Stir in the parsley, squeeze in a little lemon juice to taste, and season with a pinch more black pepper if you like.
  6. Drain the potatoes well and return them to the pot. Add the remaining 20 g butter and remaining 50 ml milk, then mash until creamy and smooth.
  7. Serve the gammon steaks with the mash and spoon over the parsley sauce. Finish with an extra squeeze of lemon at the table if you like.

Recipe notes

Tips

  • For the smoothest mash, drain the potatoes thoroughly, then let them steam-dry in the hot pot for 1 minute before mashing.
  • Keep the parsley sauce at a gentle simmer and whisk often so it stays silky and does not catch on the base of the pan.
  • If serving anyone vulnerable, make sure the gammon is piping hot all the way through before serving.

Substitutions

  • Replace Fresh parsley with Fresh chives for a milder, oniony finish.
  • Replace Lemon with Orange for a softer, sweeter citrus balance.
  • Replace Whole milk with Low-fat milk for a lighter sauce and mash.

Storage

  • Refrigerate up to 2 days
  • Cool leftovers quickly and refrigerate in airtight containers. Reheat the mash and sauce gently with a splash of Whole milk until piping hot; warm the Cured ham in a frying pan over medium heat until hot throughout.
