Instructions

Get Prepped
1

Preheat your oven to 220°C/200°C fan/gas mark 7.

Chop the potatoes into 2cm chunks (no need to peel).

Halve, peel and thinly slice the onion. Trim the root and dark green leafy part from the leek and discard. Halve lengthways, then thinly slice. 

Halve the tomatoes and pop into a medium bowl along with the French dressing. Set aside.

Roast the Potatoes
2

Pop the potato chunks onto a large baking tray. Drizzle with oil, season with salt and pepper, sprinkle over the dried rosemary, then toss to coat.

Spread out in a single layer. TIP: Use two baking trays if necessary.

When the oven is hot, roast on the top shelf until golden, 25-35 mins. Turn halfway through.

Soften the Veg
3

Meanwhile, heat a drizzle of oil in a large frying pan on medium-high heat.

Once hot, add the onion and fry for 2 mins.

Add the leek and season with salt and pepper. Fry, stirring occasionally, until both veg are softened, 4-5 mins.

Once softened, transfer to another medium bowl - keep the pan, you'll use it again.

Mix Things Up
4

Add the mustard, onion marmalade, flour, salt and egg (see pantry for all three amounts) to the bowl of onion and leek.

Season with salt and pepper, then mix well.

Crumble in the Greek style salad cheese and mix again until combined. TIP: Lift out some of the mixture with a spoon. If it's too wet and doesn't hold its shape, add a little more flour. 

Fry the Fritters
5

Return the frying pan to medium-high heat with enough oil to coat the bottom.

Once the oil is hot, place heaped tablespoons of the fritter mixture (in batches) into the pan. Flatten slightly with the back of the spoon, then fry until golden and cooked through, 3-4 mins each side. TIP: Don't flip them too early, they need time to set.

Once cooked, transfer to a plate lined with kitchen paper.

Keep cooking in batches until all the mixture is used up - you should get 3-4 fritters per person. TIP: Add extra oil in between batches if needed. 

Finish and Serve
6

Add the baby leaves to the bowl of tomatoes and toss together.

Share the fritters between your plates, then serve the salad and roast potatoes alongside.

Finish with a dollop of mayo (see pantry for amount) for dipping.

Enjoy!

Review summary

Updated on Feb 2026
  • Flavour: Many enjoyed the unique combination, though some found the mustard overpowering; consider adjusting to taste.
  • Ease of prep: Generally easy to make, though a few found the fritters tricky to form or cook properly.
  • Suggestions: Use a stronger cheese like cheddar instead of feta for more flavour; reduce mustard if sensitive to it.
  • Portions: Some found the meal filling, while others felt the portion size was too small, especially for the fritters.
  • Texture: Several noted the fritters could be improved; try cooking longer or adding a raising agent for a lighter texture.
