Ingredients and Substitutes
- baby potatoes: new baby potatoes, jersey royals, charlotte potatoes or any other small waxy potatoes will work great! Make sure to cut large ones in half in order for them to cook at the same time.
- mixed dried herbs: can be replaced with dried thyme or oregano. Don’t use fresh herbs as they will burn in the oven.
- olive oil: will be used for coating the potatoes before roasting as well as in dressing.
- eggs: choose free-range eggs if you can. The bright orange yolk looks beautiful on this no mayo tuna salad.
- capers: use small capers. Capers are bursting with sharp vinegary flavour, so you ideally want to use small little pearls that make it into each bite and do not overpower other flavours. Our favourite varieties of capers are surfines and capucines.
- sundried tomatoes: in oil, drained and dabbed with a piece of paper towel, then sliced into thin strips.
- spinach: we used baby spinach. Replace spinach with watercress, rocket or mixed baby leaves.
- tinned tuna: in brine or spring water, drained.
- red onion: can be replaced with spring onion.
- cucumber: we used English cucumber.
- honey: clear runny honey will be easier to mix with the rest of the dressing ingredients.
- Dijon mustard.
- cider vinegar: can be replaced with white wine vinegar.
How to Make Tuna Nicoise with Honey Mustard Dressing?
Preheat the oven to 220°C Fan. Cut the bigger baby potatoes in half. Place the potatoes in a large bowl, drizzle with a tablespoon of olive oil, and add the mixed dried herbs and some salt. Shake the bowl to cover the potatoes in seasoning and tip onto a baking tray, spread out. Cook in the oven for 35-40 minutes, turning them once halfway through, until tender and browned.


In the meantime, make the dressing by mixing extra virgin olive oil, mustard, honey and vinegar. Season with salt and pepper.
Cook the eggs in boiling water for 6-7 minutes. Then immediately place in cold water for a few minutes. Peel the eggs and cut them in half. You should have a soft yolk. If you prefer hard-boiled eggs, cook them for longer.
Slice the sundried tomatoes into thin strips, and thinly slice the red onion and cucumber. Divide the spinach between two plates. Scatter the capers, sundried tomatoes, red onion and cucumber on to. Add the tinned tuna in small piles on top.
Once the potatoes are cooked, add them to the salad alongside the soft-boiled eggs and drizzle everything with honey-mustard dressing!
