Gammon Steak with Parsley Sauce and Chips

A plate of gammon steak with parsley sauce and chips is classic British comfort food: salty, cured pork served hot with a mild, creamy white sauce and crisp-edged potatoes. The gammon brings savoury depth and a firm, meaty bite, while the parsley sauce softens its saltiness with butter, milk, fresh herbs and a little mustard for gentle sharpness. Oven-baked Yukon Gold chips keep the meal practical without losing the familiar chip-shop appeal. It is a straightforward dinner that works well when you want something filling, unfussy and properly satisfying, with the sauce doing most of the work in tying the plate together.

Why this recipe works

  • Crisp and creamy contrast: Golden oven chips and a smooth parsley sauce give the plate more texture than a simple ham-and-potato dinner.
  • Balanced savoury flavour: Salty gammon is rounded out by buttery milk sauce, fresh parsley and a small amount of Dijon for gentle sharpness.
  • Straightforward timing: The chips bake while the gammon and sauce are prepared, keeping the meal manageable without complicated steps.

Ingredient notes

  • Check the gammon’s saltiness: Cured gammon steaks vary in salt level. If they seem very salty, soak briefly, pat dry well and season sparingly.
  • Use fresh parsley if possible: Fresh parsley gives the sauce its clean colour and herbal lift; dried parsley will taste flatter and less bright.
  • Mustard adds balance: Dijon brings mild acidity and helps cut through the richness of the milk-and-butter sauce.

Texture tips

  • Keep the chips spread out: Give the potatoes space on the tray so they roast rather than steam, turning them halfway for even browning.
  • Add the milk gradually: Whisk the milk into the roux in stages to keep the parsley sauce smooth and free from lumps.
  • Rest the gammon briefly: A short rest after searing helps the steaks stay juicy while the sauce is finished.

Common mistakes

  • Salting too early: Taste before adding the final seasoning, as the gammon and mustard may already provide enough salt.
  • Boiling the sauce hard: Keep the parsley sauce at a gentle simmer once the milk is added; high heat can make it catch or turn uneven.
  • Letting the chips sit too long: Serve soon after the gammon is cooked so the chips keep their crisp edges.

Make-ahead tips

  • Best served freshly cooked: The chips and gammon have the best texture straight after cooking, while the sauce is still warm and loose.
  • Reheat gently: Warm leftover gammon and chips on a tray at 200°C (390°F) until piping hot, and reheat the sauce slowly in a pan.
  • Keep sauce separate: Store the parsley sauce separately from the gammon and chips so it can be loosened and reheated without making the chips soggy.

  1. Heat the oven to 220°C (430°F). Cut the potatoes into chip shapes, then toss on a baking tray with 1 tsp of the fine sea salt and a pinch of the black pepper.
  2. Bake the chips for 30 to 35 minutes, turning halfway, until deeply golden and crisp at the edges. Keep them in the oven while you cook the gammon and make the sauce.
  3. Meanwhile, finely chop the fresh parsley. Pat the gammon steaks dry and season lightly with the remaining black pepper.
  4. Melt 15 g of the unsalted butter in a frying pan over medium-high heat. Add the gammon steaks and sear for 2 to 3 minutes per side until nicely browned and piping hot through; transfer to a warm plate to rest.
  5. For the parsley sauce, melt the remaining unsalted butter in a saucepan over medium heat. Stir in the plain flour and cook for 1 minute, stirring, until it smells biscuity but has not coloured.
  6. Gradually whisk in the whole milk until smooth, then bring to a gentle simmer and cook for 3 to 5 minutes until thickened enough to coat the back of a spoon. Stir in the Dijon mustard, then take off the heat and fold through the fresh parsley; taste and adjust with the remaining fine sea salt if needed.
  7. Serve the gammon steaks with the chips and spoon over the warm parsley sauce. Grind over a little extra black pepper if you like.

Recipe notes

Tips

  • If your gammon steaks are very salty, soak them in cold water for 20 minutes, then pat dry before cooking; this helps balance the seasoning.
  • Keep the parsley sauce just below a boil once the milk is added, and stir often, so it stays smooth and creamy.
  • If serving anyone who should avoid undercooked foods, make sure the sauce is simmered properly and the gammon is piping hot throughout.

Substitutions

  • Replace Dijon mustard with whole-grain mustard for a milder heat and a coarser texture.
  • Replace Fresh parsley with fresh chives for a gentler, oniony finish.

Storage

  • Refrigerate up to 2 days
  • Cool leftovers quickly and refrigerate in airtight containers. Reheat the gammon and chips on a baking tray at 200°C (390°F) until piping hot; warm the parsley sauce gently in a saucepan, stirring, and add a splash of whole milk if it has thickened.
