Why we love this recipe:
Aside from being delicious, red capsicum/bell pepper has a lot of health benefits! They’re a great source of Vitamins A, B6 and C, and are packed full of antioxidants.
I enjoy eating capsicum both raw and cooked. Serve strips of capsicum on a dip platter or add to your salad for a burst of colour. Capsicum is a great addition to pasta sauces and on pizza.
This Roasted Red Pepper Soup is simple to prepare and the flavour is truly delicious. Make a big batch, and store some serves in your freezer for those days you need a quick lunch or dinner!
Ingredients in this recipe:
Please see the recipe card further along in the post for exact quantities of ingredients and the full method.
Red Capsicums/Bell Peppers and Tomatoes – our flavour base for the soup. We roast them for extra depth of flavour and sweetness.
Brown/yellow onion – indispensable as a flavour base in this soup.
Olive oil – to roast the vegetables and blend with the fresh basil.
Vegetable stock – you can make your own or use a commercial variety.
Dried Oregano – works well with the vegetables and also complements the basil oil.
Fresh Basil – we use fresh basil to make the basil oil. This is optional, but it works so well and is very easy to make, so I highly recommend serving the soup with this.
Sea salt and pepper – to taste.
Step by Step Instructions:
- Prepare your vegetables and put them on a baking tray.
- Roast until they are tender.
- Add the roasted vegetables to a blender, along with the stock.
- Blend until a smooth consistency. Season to taste. Then, prepare your basil oil to drizzle over the top.
Tips for Success and FAQs:
Make sure that the vegetables are cooked through before attempting to blend them. It will be impossible to blend it smoothly if they are slightly undercooked.
You can use an immersion blender – I do. You will get a smoother, creamier texture if you use a blender. However, it is important to understand that blending hot liquids in a blender can be dangerous and could result in severe burns.
If you do use a blender for hot liquids, you must be careful. You will need to remove the central cap in the blender lid and then cover the lid with a folded tea towel to let the steam escape. Hold the lid on securely and blend on a low speed. This will allow steam to escape so that it doesn’t build up. Not doing this can pose a risk that soup may overflow out of the blender.
Make this soup your own. The basic recipe is vegan and gluten-free and delicious as it is. However, if you do not have specific dietary restrictions you can tailor it to your own requirement – perhaps a drizzle of cream instead of the basil oil.
The soup will last for 3 days in the fridge.
Yes, soup is one of the best meals to make ahead because it freezes so well.  Make a big batch and allow the soup to cool completely before storing in freezer-safe containers. The soup can be frozen for about 3 months. Be sure to label the container with the name and date – frozen objects can be difficult to identify.
I would freeze the soup without the basil oil, and prepare this fresh when serving.

Notes
- Red capsicums (bell peppers) have the best flavour and are ideal for this recipe.
- I have used vegetable stock in this recipe to keep it vegan, but you could also use chicken stock.
- The herb oil also works well with parsley, if you don’t have any basil.
- If you do use a blender for hot liquids, you must be careful. You will need to remove the central cap in the blender lid and then cover the lid with a folded tea towel to let the steam escape. Hold the lid on securely and blend on a low speed. This will allow steam to escape so that it doesn’t build up. Not doing this can pose a risk that soup may overflow out of the blender.
