Slow cooker carrot and coriander soup uses carrots, a potato, onion, vegetable stock, ground coriander, and fresh coriander. Everything goes into the slow cooker together and cooks on LOW for 6 hours, then blends smooth. The recipe serves 4 and takes about 6 hours 20 minutes total.

The potato is what makes this soup creamy without any added cream or dairy. Starchy potato breaks down slowly over 6 hours and thickens the broth from the inside out, so the finished soup coats a spoon cleanly. Without it, the texture is thinner and blending alone doesn’t fix it.

The fresh coriander goes in after blending, never before. Six hours of low heat cooks out coriander’s volatile oils, leaving only a faint background note by the finish. Stirring the fresh herb through at the end keeps that clean, herbal flavour intact in every bowl.

Slow Cooker Carrot and Coriander Soup: carrots, potato, and vegetable stock on LOW for 6 hours, then blended smooth. Serves 4. Only 123 calories per serving

Ingredients

• Soup

• 1 medium onion (approx 140g), peeled and cut into eighths

• 575g carrots, peeled and cut into 2.5cm pieces

• 1 medium potato (approx 300g), peeled and cut into 2.5cm pieces

• 1.5 litres vegetable stock

• ½ tsp ground coriander

• ¼ tsp salt

• ¼ tsp black pepper

• To Finish

• 3 tbsp fresh coriander, chopped

Directions

• Place the onion, carrots, potato, vegetable stock, ground coriander, salt, and pepper into a 3.5-litre slow cooker. Stir briefly to combine.
• Put the lid on and cook on LOW for 6 hours, until all the vegetables are completely tender.
• Remove the lid and allow the soup to cool for 15 to 20 minutes before blending. (Hot liquids can expand rapidly under pressure.)
• Blend in batches using a blender or NutriBullet until the soup is silky smooth, or blend directly in the slow cooker using a stick blender.
• Stir through the freshly chopped coriander and taste for seasoning. Add more salt and pepper if needed, then serve hot.

FAQs

Do the vegetables need browning before they go in?

No, this recipe is a true dump-and-go: everything goes in raw and the slow cooker handles the rest. Browning onions first adds caramelised depth, though in a soup this light the difference is marginal and the simplicity is the whole point. Skip the extra pan and add everything directly; the 6 hours does enough.

What size slow cooker do I need?

A 3.5-litre slow cooker fits this recipe comfortably, which is the small to medium size found in most UK households. A larger 5- or 6-litre cooker also works, with the only difference being the soup may reduce slightly more as it cooks. Top it back up with a splash of extra stock before blending if it looks too thick.

Can I use ground coriander without the fresh coriander?

Ground coriander on its own produces a warmer, earthier soup with no brightness or freshness at the finish. Fresh coriander carries the top note that makes this soup taste vibrant rather than just earthy, and removing it shifts the whole profile. Keep both in if you can; they do different jobs and work better together than either does alone.

What other slow cooker vegetable soup is worth making this week?

A squash-based soup is the natural companion to this recipe: creamy, sweet, and just as easy to make. A slow cooker squash and coconut soup on easypeasyslowcook.com follows a similar dump-and-blend method, with coconut milk adding creaminess in place of potato. The coconut base gives it a completely different flavour profile, so the two soups contrast well side by side.

What if I want something heartier to serve after this?

The chicken, bacon, and potato combination brings a completely different weight to the table than this light vegetable soup. A slow cooker chicken, bacon and potato stew on easypeasyslowcook.com is the natural follow-on: richer, meatier, and ready from the same pot. They share the same potato base yet land at entirely opposite ends of the table.
