Mushroom and egg salad brings browned, savoury mushrooms into a familiar creamy lunch dish.

Mushroom and egg salad brings browned, savoury mushrooms into a familiar creamy lunch dish. The egg pieces stay distinct, while dill and Dijon keep the dressing lively. Cooking away the mushroom liquid matters more than adding extra mayonnaise: damp mushrooms make a thin dressing and soften the eggs. This version uses a modest amount of dressing and a single skillet for the vegetables. Start the eggs first so they can cool while the mushrooms cook.

Ingredients

Instructions

  1. Cook the eggs

    Cover eggs with cold water, bring to a boil, cover and turn off the heat. Leave 12 minutes, then cool in ice water for 5 minutes. Peel and chop.

  2. Brown the vegetables

    Heat oil in a 28 cm (11 inch) skillet over medium-high heat. Cook mushrooms and onion for 12–15 minutes, stirring, until the liquid disappears and edges brown. Stir in garlic for 30 seconds.

  3. Cool before dressing

    Spread vegetables on a shallow plate for 10–15 minutes until no longer warm. Whisk mayonnaise, Dijon, lemon, salt and pepper in a bowl.

  4. Combine gently

    Fold eggs, mushrooms and dill into the dressing without crushing the egg pieces. Serve promptly or cover and refrigerate.

Doneness checks

Helpful tips

  • Dice mushrooms small for even spoonfuls.
  • Let liquid evaporate before cooling.
  • Cool vegetables before adding mayonnaise.
  • Fold with a spatula to retain egg pieces.

Troubleshooting

  • The mushrooms retained liquid or were still warm. Cook them until dry and cool them before dressing.
  • Let liquid evaporate before cooling.

Serving ideas

  • Spoon over rye toast.
  • Fill lettuce cups.
  • Serve beside sliced cucumber.
  • Offer with a baked potato.

Substitutions

Use button mushrooms in the same amount; their flavour is milder. Plain thick yogurt can replace half the mayonnaise for a tangier dressing.

Variation

Add 1 tbsp finely chopped drained dill pickle for a sharper salad.

Make ahead

Boil eggs and cook mushrooms a day ahead; refrigerate separately and combine when needed.

Storage and reheating

Refrigerate covered at 4°C (40°F) or below for up to 3 days. Do not freeze; the eggs and dressing lose their texture.

Food safety

Use clean utensils and wash produce. Keep perishable ingredients refrigerated at 4°C (40°F) or below. Refrigerate perishable leftovers promptly, within 2 hours, or within 1 hour above 32°C (90°F).
