Preparation Time 15-20 minutes
Cooking Time 180-420 minutes
Total Time 195-440 minutes
Level of Difficulty Medium

Ingredients

  • 1.2 kg vine-ripened tomatoes
  • 1 tablespoon olive oil
  • 5 garlic cloves
  • 130 grams roughly chopped red onion
  • 2 teaspoons mixed herbs
  • 1 vegetable stock cube
  • 400 ml freshly boiled water
  • 1 teaspoon sugar (caster or granulated)
  • 2 tablespoons tomato paste
  • A handful of basil leaves
  • Black pepper to taste

Step 1: Prepare and Roast the Tomatoes

Preheat your oven to 180°C (350°F).

Cut each tomato in half and place them in a baking tray.

Drizzle with olive oil and crush the cloves of garlic, then add them to the tray.

Roast the tomatoes for approximately 35 minutes, until they are soft and slightly caramelized.

Step 2: Transfer Ingredients to the Slow Cooker

Once the tomatoes are roasted, transfer the chopped red onion, roasted tomatoes, and any juices from the pan into the slow cooker.

Add two of the cloves of garlic by squeezing the soft garlic out of the skin.

Then, add the mixed herbs, vegetable stock cube, 400 ml (1.5 cups) of water, sugar, and tomato puree to the slow cooker.

Step 3: Cook the Soup

Cover the slow cooker and cook the soup on high for approximately 3 hours or on low for 6-7 hours.

This slow-cooking process will allow the flavors to meld together beautifully.

Step 4: Blend the Soup

Once the cooking time is complete, use a stick blender or jug blender to blend the soup until it reaches a smooth consistency.

Be careful if the soup is hot, and blend in batches if using a jug blender to avoid overfilling.

Step 5: Serve and Garnish

After blending, serve the soup in bowls.

Season with black pepper to taste, and garnish with some torn basil leaves for a fresh and aromatic finish.

Enjoy your homemade roasted tomato soup!
