• Roma tomatoes - or regular tomatoes. Try and buy the juiciest, ripest tomatoes you can! Although the beauty about making soup with roasted tomatoes is that you can use less than perfect tomatoes and it will still taste great!

• Brown onion - or yellow onion.
• Red capsicum - also known as red pepper or red bell pepper.
• Garlic - use fresh garlic cloves and mince them yourselves, or use store-bought minced garlic if you are pressed for time!
• Olive oil - for roasting the vegetables in. Using olive oil adds a delicious flavour too!
• Salt and pepper - to season the soup.
• Tomato paste - adds an extra depth of tomato flavour.
• Vegetable stock liquid - or make your own using powdered vegetable stock mixed with water.
• Fresh basil - adds a delicious flavour to the roasted tomato soup.

Expert Tips

• Roast the tomatoes - until tender and the edges are beginning to colour. This will create a flavour-packed soup with a beautiful silky smooth texture.
• Sugar - underripe tomatoes can make the soup taste a little sour, however this is easy to fix! Stir in a pinch of white sugar to taste.
• If pureeing the soup in a blender - leave to cool slightly for 5 minutes before blending to avoid steam building up in the blender which can cause the top to come off and can result in burns.
• Storage - store any leftover roasted tomato soup in an airtight container in the fridge for up to 3-4 days.
• Serving ideas - hot buttered toast, cheese toasties, homemade rolls or scrolls, or fresh crusty bread!
