Spring onion, tahini and harissa smash potato salad
Smashed potato salad season has arrived
Looking for a smashed potato salad with a twist? Meet the Middle Eastern-inspired potato salad you didn’t know you needed – my spring onion, tahini and harissa smash potato salad. This has everything going for it, and by that I mean that it’s creamy, spicy, tangy, and crunchy in all the right places. It’s the perfect side dish for BBQs, picnics, Easter buffets or just when you want to give your basic spud salad a big, bold upgrade.
I’ve taken crispy smashed potatoes (which I typically get a bit obsessed over) and given them the salad glow-up with a mouth watering tahini-harissa dressing and loads of crunchy spring onions for a bit of added texture. It’s light yet indulgent, spicy but balanced, and honestly, I could eat the whole bowl straight from the fridge. Please don’t judge.
The dressing that delivers
Aside from potatoes, this creamy, punchy dressing is the star of the show and is made from:
Rose harissa (a spicy, fragrant chilli paste)
Tahini (rich sesame paste)
Greek yoghurt
Mayonnaise
Lemon juice
Spring onions
Nigella seeds
Salt & pepper
It’s loaded with Middle Eastern flavour and it clings to each golden edge of the smashed potato like an absolute dream.
FAQs
What is rose harissa and how is it different?
Rose harissa is a North African chilli paste that includes rose petals or rose water for a subtle floral note. It’s slightly sweeter and more complex than regular harissa, with layers of spice and smokiness. Think of it as harissa’s fancy cousin, so still fiery, but with depth and a little hint of perfume from the rose. Basically, it’s really nice.
What else can I use harissa for?
Once you’ve got a jar open and need to use it asap, you can stir rose harissa into:
Marinades for chicken, lamb or tofu
Soups and stews
Pasta sauces (spicy tomato harissa rigatoni is a go-to)
Roasted veg (try it on carrots or cauliflower)
Toasted sandwiches or mayo to add a spicy element
What is tahini?
Tahini is a paste made from ground sesame seeds, and it’s a staple in Middle Eastern and Mediterranean cooking. It’s rich, nutty, slightly bitter, and creamy, kind of like a seed butter. It adds silkiness that balances spicy or citrusy ingredients beautifully. Most people may recognise it from adding it to hummus. And who doesn’t love to dunk some pitta in a tub of hummus?!
What else can I use tahini for?
Tahini isn’t just for hummus, oh no babs. Try it in:
Salad dressings or dips
Tahini brownies or cookies
Stirred into porridge with honey
Swirled into roasted veg
Drizzled over toast or pancakes
It’s a really versatile ingredient and lasts for ages in the cupboard so don’t throw the pot out! Make sure you use up the full thing.
How long will this potato salad keep?
This smashed potato salad will keep in the fridge for up to 3 days in an airtight container, but to be honest it’s best enjoyed fresh as once the dressing has been added, the crunchiness will start to die down a little. Best served slightly chilled or at room temp.
Will it be spicy?
It has a gentle heat, thanks to the harissa, but it’s well balanced by the creamy tahini, mayo and yoghurt. If you’re heat-sensitive, you can either simply use less harissa, add a drizzle of honey or swap for a milder paste or paprika.
How can I make it vegan?
Yep! So to make it vegan you’d need to use a plant-based mayo or even a coconut yoghurt. I’d check the tahini and harissa are definitely vegan, most are but always worth a double check! Everything else should be good to go!

Metric

Instructions
- Slice your potatoes in half (or quarters if needed to make them all the same) and place into a saucepan. Cover with cold water and add a big pinch of salt. Bring to a boil and cook for 15-20 minutes until tender, then drain into a colander and leave to dry for 10 minutes.
- While the potatoes are steam drying, preheat the oven to 200ºc fan/220ºc/400ºf. In a small bowl, mix together the smoked paprika, garlic granules, dried mixed herbs, olive oil and a pinch of salt and black pepper. Tip all of the potatoes onto a baking tray (you might need 2) and use the base of a mug or bowl to smash them down flat.
- Brush the potatoes with the spiced oil mixture and pop the trays into the oven. Bake for 45 minutes, turning halfway, until super crispy. While they're in the oven, make your dressing.
- In a large mixing bowl, combine the tahini, yoghurt, lemon, mayonnaise, harissa, a pinch of salt and pepper and the sliced spring onions. Toss the crispy potatoes through the dressing and serve up in a large bowl, before sprinkling with the remaining spring onions and the nigella seeds. Serve with marinated barbecued chicken thighs for a delicious summer lunch.
