Moroccan Spiced Sweet Potato Soup, Harissa Sweet Potato Soup
This moroccan sweet potato soup recipe simmers sweet potatoes with carrot, onion and garlic in vegetable stock, blooms cumin, coriander, cinnamon and harissa in olive oil, then blends everything smooth and finishes it with lemon and a yogurt swirl. One serving is about 465 g.
Sweet potato soup is a modern Moroccan table favourite, built on the same spice cupboard as harira and tagines — cumin, coriander, cinnamon and harissa — but lighter and quicker than the classic bean and lentil soups. Sweet potatoes arrived in North Africa through Atlantic trade and settled into everyday cooking; cooks in Marrakech and Casablanca now simmer them with the spices that define Moroccan flavour, and finish the bowl with lemon and yogurt the way they would a tagine.
Pairs well with: Crusty bread and a lemon wedge

A good Moroccan sweet potato soup is velvety, bright orange and warmly spiced — never thin, never dull, never burning hot.
Execution Methodology & Culinary Technique
Prep Stage: Chop Vegetables and Measure Spices
15 Mins • Chop Vegetables + Measure Spices
Peel and chunk the sweet potatoes, peel and slice the carrots, chop the onion and mince the garlic. Measure the cumin, coriander, paprika and cinnamon into one small bowl and the harissa into another, so the spices can go into the pot in one move — blooming them takes less than a minute and they burn fast.
Maestro Tip: Measure the spices before the pot goes on — once the onion is soft you have seconds, not minutes, to get them in.
8 Mins Medium heat, about 160°C (320°F)
Warm the olive oil in a large pot over medium heat. Add the onion and cook for 5 minutes until soft and translucent, then add the garlic and cook 1 minute more until fragrant.
Do not let the garlic brown — browned garlic turns bitter and the whole pot tastes of it.
Done when: Onion soft and sweet-smelling, garlic fragrant but still pale.
2 Mins Medium heat, about 160°C (320°F)
Add the cumin, coriander, paprika and cinnamon and stir for 30 seconds until fragrant, then stir in the harissa paste and cook 30 seconds more.
Keep stirring — dry spices scorch in seconds on a hot pot base, and scorched cumin tastes bitter.
Done when: A dark, fragrant spice paste coating the onion, smelling warm and smoky.
20 Mins Gentle simmer, about 100°C (212°F)
Add the sweet potato, carrot and vegetable stock, stir once, and bring to a gentle simmer. Cover and cook for 18–20 minutes until the sweet potato is completely tender and breaks apart with a spoon.
Keep the simmer gentle — a hard boil splashes and the potatoes break up before they are cooked through.
Done when: Sweet potato collapsing-soft, carrot tender, broth orange and fragrant.
7 Mins Hot, about 90°C (194°F)
Take the pot off the heat and blend the soup until completely smooth, in batches if needed. Stir in the lemon juice and salt, taste, and add a little more harissa or lemon if it needs it. Ladle into warm bowls, swirl a spoonful of plant yogurt over each one, dust with a pinch of smoked paprika and scatter the fresh coriander on top.
Blend in batches and never fill the blender more than half full with hot soup — steam builds pressure fast.
Done when: A velvety orange soup with a pale yogurt swirl, red paprika dusting and green coriander on top.
Finishing Touches & Plating
Ladle the soup into warm bowls, swirl the yogurt over the top and dust with paprika — the swirl is not decoration, it is the cool, tangy contrast that balances the harissa heat.

Vitamin A and Fibre
Sweet potato and carrot give vitamin A and about 9 g of fibre per serving, which supports steady digestion.
Filling but Light
At about 302 kcal a bowl with no cream and no coconut milk, it is a filling lunch that stays light.
Spice, Not Salt
Cumin, coriander and cinnamon bring the flavour, so the soup needs very little salt to taste seasoned.
Food Pairings
To optimize nutrient absorption and elevate the sensory depth, pair with these authentic accompaniments:
Sides
Crusty Bread
Crusty bread is made for this soup — it soaks up the spiced broth and turns a bowl into a full lunch.
Vegetables
Cucumber and Tomato Salad
A crisp cucumber and tomato salad with lemon cools the palate between spoonfuls of warm, spiced soup.
Drinks
Mint Tea
A squeeze of lemon and a mint tea on the side are the Moroccan way to finish — bright, fresh and cleansing.
Sauces
Extra Harissa
A spoonful of extra harissa on the side lets everyone set their own heat, instead of the cook guessing.
Complete menu
Serve the soup with crusty bread and a cucumber and tomato salad, follow with grilled fish or a chickpea tagine, and finish with mint tea.
Digestive Guardrails
To prevent digestive distress, sluggishness, or palate clash, avoid pairing the dish with these elements:
Overfilling the Blender
Blending a full blender of hot soup can blow the lid off — blend in batches, hold the lid down with a towel, and never fill past half. This is general guidance, not medical advice.
Adding All the Harissa at Once
Adding all the harissa at once can make the soup too hot to enjoy — add half, taste, then add more. This is general guidance, not medical advice.
General information only, not medical advice — consult a doctor for personal dietary decisions.

Moroccan chicken tagine is the dish Morocco is best known for: chicken braised slowly with onions, ginger and saffron, then finished with salty preserved lemon and green olives. This moroccan chicken tagine recipe uses a heavy pot instead of a clay tagine, so anyone can make it — the conical lid's job is done by a tight-fitting lid and a gentle flame. One serving is about 315 g.
