Introduction
This roasted red pepper soup is a comforting and flavorful dish perfect for cooler days. Enhanced with fragrant spices and topped with crispy wholemeal croutons, it makes for a satisfying, wholesome meal that’s quick to prepare.

Ingredients
- 2 red onions, roughly chopped
- 2 carrots (250g), roughly chopped
- 1 tsp olive oil
- 2 garlic cloves, roughly chopped
- 200g jarred roasted red peppers (drained weight), drained and roughly chopped
- 1 tsp rose harissa paste
- 1 tsp cumin seeds
- 1 tsp Kashmiri chilli powder (or any other chilli powder)
- 850ml low-salt vegetable stock
- 4 tbsp natural yogurt, to serve
- 100g slightly stale wholemeal crusty bread, cut into cubes
- 1 tsp olive oil (for croutons)
Instructions
- Step 1: Blitz the onions and carrots together in a food processor until finely chopped, or chop finely by hand. If making the croutons, preheat the oven to 220°C (200°C fan)/gas mark 6.
- Step 2: Heat 1 tsp olive oil in a large saucepan over medium heat. Cook the chopped onion and carrot with a pinch of salt for 5–6 minutes, stirring frequently until they start to soften.
- Step 3: Stir in the garlic and roasted red peppers, cooking for 1 minute more until fragrant.
- Step 4: Add the rose harissa paste, cumin seeds, and chilli powder. Cook for 1 minute while stirring to release the spices’ aroma.
- Step 5: Pour in the vegetable stock, increase the heat to medium-high, and bring the soup to a boil. Reduce heat and simmer for 15–18 minutes until the vegetables are soft.
- Step 6: Meanwhile, prepare the croutons by tossing the bread cubes with 1 tsp olive oil and seasoning well. Spread on a baking tray and bake in the oven for 8–10 minutes until deeply golden and crispy.
- Step 7: Transfer the soup mixture to a high-powered blender or use a hand blender to blend until smooth. Season to taste.
- Step 8: Ladle the soup into bowls, add a dollop of natural yogurt on top, and scatter with the crispy croutons before serving.
Tips & Variations
- For a richer flavor, roast your own red peppers instead of using jarred.
- Adjust the chilli powder to suit your heat preference or omit for a milder soup.
- Swap natural yogurt for sour cream or crème fraîche for a different tangy touch.
- Use gluten-free bread for croutons to make this recipe gluten-free.
Storage
Store leftover soup in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or in the microwave until piping hot. Keep croutons separate and add just before serving to maintain their crispness.

FAQs
Can I make this soup vegan?
Yes, simply skip the natural yogurt or replace it with a plant-based alternative like coconut yogurt to keep it vegan-friendly.
What can I use if I don’t have a blender?
