Yields: ~5kg finished salad (40 x 125g servings)
Perfect as a cold side for buffets, picnics, or light lunches
5.5–6kg baby potatoes or waxy salad potatoes (skin on, halved if large)
200ml olive oil (~¾ cup)
Zest + juice of 4 lemons
3–4 tbsp white wine vinegar
3 tsp Dijon mustard (optional)
4–5 garlic cloves, finely minced
2 medium red onions, finely chopped (optional; soak 10 mins in water to mellow)
2 tbsp sea salt (adjust to taste)
1 tsp black pepper
1 large bunch fresh parsley, finely chopped
1 large handful fresh dill or mint, chopped (or a mix — ~1 cup total)
Boil the Potatoes:
Boil potatoes in well-salted water until just fork-tender (10–15 mins).
Drain and let cool slightly (warm potatoes absorb dressing best).
Make the Dressing:
In a large jug, whisk together olive oil, lemon zest + juice, vinegar, mustard, garlic, salt, and pepper.
Combine:
Place warm potatoes and red onion in a very large bowl.
Pour over the dressing and toss gently to coat.
Add chopped herbs and toss again.
Rest & Chill:
Rest at room temp 30 mins, then refrigerate for 2–24 hours.
Stir gently before serving, and adjust seasoning if needed.
Serve in wide, shallow bowls or trays for easy access.
Garnish with lemon wedges and a sprinkle of chopped herbs before serving.
Can be made 1–2 days ahead; just drizzle with a little more olive oil to freshen it up.
