Giant Pearl Couscous Salad with Roasted Vegetables

This easy giant pearl couscous salad combines roasted sweet potato, butternut squash, rose harissa, feta, herbs, and pomegranate seeds for a warm, flavour-packed vegetarian meal or side dish.

This easy giant pearl couscous salad combines roasted sweet potato and butternut squash with chewy pearl couscous, rose harissa paste, feta cheese, fresh herbs, and pomegranate seeds.

It is great warm or cold, it's slightly sweet, and it's packed with flavour and texture.

The recipe works well as a vegetarian main course, meal prep lunch, or colourful side dish.

Between the roasted squash, chewy couscous, salty feta, and spoonful of rose harissa, it feels generous and deeply satisfying without being complicated to make.

Roasting the vegetables properly matters here. You want caramelised edges and concentrated sweetness rather than steamed cubes of squash. Taking the time to spread the vegetables out well on the tray gives you much better flavour. That sweetness then balances the warmth of cumin and the subtle chilli heat in the harissa.

Pearl couscous is especially good in recipes like this because it adds texture instead of disappearing into the background. Unlike standard couscous, which behaves more like a grain, pearl couscous feels closer to tiny pasta. It keeps its bite and gives the salad structure.

Try it as a side with Persian Grilled Vegetable Tofu Skewers or Portobello Mushroom Steaks.

Rose Harissa

Harissa is a North African chilli paste made with peppers, garlic, oil, and spices like cumin and coriander.

Traditional harissa is often smoky, earthy, and quite fiery, while rose harissa is softer and more aromatic.

It usually includes rose petals, which add a subtle floral note that works especially well with sweet vegetables like squash and sweet potato.

If you have only used standard harissa before, rose harissa is worth trying when you want warmth and complexity without overwhelming heat. Try it in Lentil Stew with Harissa or Roasted Vegetable Quinoa Salad.

Pearl Couscous

Pearl couscous, also called giant couscous or Israeli couscous, is a small round pasta made from toasted wheat flour.

Unlike regular couscous, which is tiny and fluffy, pearl couscous is larger, chewier, and more similar to pasta in texture.

It is usually boiled like pasta and works well in salads, grain bowls, soups, and warm side dishes because it holds its shape and absorbs flavour well.

Ingredients

• Sweet potato. Sweet potato gives the salad softness and sweetness. It roasts beautifully and helps balance the spice from the harissa. You could substitute carrots if needed, though the flavour will be less rich.
• Butternut squash. Butternut squash adds nuttiness and creamy texture once roasted. Pumpkin works well as an alternative if butternut squash is unavailable.
• Oil. Oil helps the vegetables caramelise rather than dry out in the oven. Olive oil is ideal for flavour, but neutral oils also work.
• Ground cumin. Cumin adds warmth and earthiness that ties the roasted vegetables and harissa together. Ground coriander can be added alongside it for extra depth.
• Giant pearl couscous. Pearl couscous provides chewiness and structure. Despite the name, it is actually pasta. Israeli couscous is the same thing in most supermarkets.
• Extra virgin olive oil. Extra virgin olive oil forms the base of the dressing and carries the flavour of the harissa through the salad.
• Rose harissa paste. Rose harissa brings spice, sweetness, and aromatic flavour. If you use regular harissa, start with a smaller amount because it can be much hotter.
• Feta. Feta adds saltiness and creamy contrast against the sweet vegetables. Goat cheese or vegan feta alternatives also work well.
• Pomegranate seeds. Pomegranate seeds add acidity, crunch, and freshness. Dried cranberries can work in a pinch, though they are sweeter.
• Parsley or mint. Fresh herbs lift the whole salad. Mint gives freshness while parsley adds grassy brightness. Using both creates the best balance.

Instructions

Follow this step-by-step photo tutorial, then scroll down to the recipe card for the full ingredients list and method.

Preheat the oven to 200°C/400°F.

Peel the sweet potatoes and butternut squash and cut them into small cubes.

Spread the vegetables evenly onto a baking sheet and drizzle with the oil, then sprinkle with the ground cumin.

Roast for 25-30 minutes, turning halfway, until golden and slightly crisp.

Meanwhile, mix the rose harissa paste into the oil and set aside.

When the vegetables are nearly roasted, cook the giant couscous according to package instructions (boil in double the amount of water for 10 minutes).

Drain then stir in the harissa infused oil.

Add the couscous to a large serving bowl and add the roasted sweet potato and squash and toss gently.

Top with the crumbled feta, pomegranate seeds and herbs.

Variations

• Add chickpeas for extra protein and fibre.
• Stir through baby spinach while the couscous is still warm.
• Replace feta with grilled halloumi.
• Use roasted carrots and cauliflower instead of squash.
• Add toasted almonds or pistachios for crunch.
• Swap rose harissa for pesto if you prefer a milder flavour profile.
• Include roasted red onions for sweetness and depth.
• Add cooked lentils for a heartier vegetarian main course.
• Use quinoa instead of pearl couscous for a gluten-free option.
• Stir through preserved lemon for extra brightness.
• Add roasted aubergine for a silkier texture.
• Top with tahini yoghurt sauce for creaminess.

Serving Suggestions

• Serve with garlic yoghurt, Vegan Aioli (Garlic Mayonnaise), or a little Chili Garlic Oil.
• Pair with beetroot balls (veggie meatballs).
• Add hummus and flatbread for a mezze-style meal.
• Spoon into lunch boxes with extra herbs.
• Add a fried egg on top for brunch.
• Use as part of a vegetarian buffet spread.
• Serve with roasted cauliflower steaks.
• Add avocado for extra richness.
• Spoon over rocket leaves for more freshness.

Storage, Freezing, Make-Ahead Advice

This salad keeps well in the fridge for up to 3 days in an airtight container. The flavours actually improve slightly as the couscous absorbs the harissa dressing.

Freezing isn't ideal as the veggies will turn a bit mushy.

For meal prep, divide the couscous and vegetables into containers and add feta and pomegranate seeds just before eating for the freshest texture.
