A classic French brasserie salad with crisp Batavia lettuce, good cooked ham, Emmental, eggs with just-set yolks and dry-fried mushrooms. Toss with a generous Dijon mustard vinaigrette, then add herbs, toasted seeds or microgreens if you fancy.
Bring a saucepan of water to the boil. Gently lower in the eggs (at room temperature) and cook for 9 minutes. Transfer them immediately to cold water, then peel and cut into quarters.
Optional step (if not using raw mushrooms): Heat a dry frying pan over medium-high heat. Add the sliced mushrooms and cook for 3–4 minutes, tossing regularly, until lightly coloured and any released moisture has evaporated. Transfer to a plate and leave to cool.
Put the oil, vinegar, mustard, salt and pepper in a clean jam jar. Close the lid tightly and shake until emulsified.
Chop the lettuce into manageable pieces and place in a large salad bowl. Add the ham, Emmental and cooled mushrooms.
Pour over most of the vinaigrette and toss thoroughly until everything is generously coated to your liking, then add the egg quarters.
Finish with the parsley, chives and any optional pumpkin seeds or microgreens.
Notes
To serve: Toss with the vinaigrette at the last moment and serve immediately, lightly chilled or at cool room temperature.
Mushrooms: Dry-frying adds flavour without oil. For the more usual brasserie version, leave the mushrooms raw and slice them shortly before serving.
Ham: Ask for one thick slice of unsmoked cooked ham. Leftover ham works too, although strongly smoked or sweet-glazed ham will change the classic flavour.
Dressing: This makes approximately 180ml / ¾ cup - a deliberately generous quantity. Refrigerate any remainder in the closed jar for 3–4 days, then bring it briefly to room temperature and shake again.
Lettuce: Batavia or curly lettuce may appear as Summer Crisp or French Crisp in the US.
Make ahead: Prepare the eggs, mushrooms, ham, cheese and vinaigrette one day ahead and refrigerate separately. Assemble and dress just before serving.
