Variations on this Roasted Tomato Soup Recipe

This particular way of cooking soup follows the same path regardless of which soup you’re making.

For any roasted vegetable soup, first season the vegetables, then roast them in the oven (without any oil), and thirdly, blend them with some homemade vegetable stock.

The final step is to mix in some unsweetened plant milk.

Other examples of my favourite roasted vegetable soups are roasted pumpkin soup and roasted sweet potato and carrot soup.

Omitting the Garlic in Your Tomato Soup

When making this roasted tomato soup recipe, you can omit the garlic if you like.

And even if you do include the garlic, be sure not to add too much or it might overpower the flavour of the soup.

Dry-roasted garlic has a pungent flavour, so if in doubt, add less than you think you need. You can always add more once you’ve tasted the soup after blending.

Homemade Vegetable Stock

You can also switch the homemade vegetable stock for plain water, but the veggie stock always adds a nice extra complexity to the flavour of any soup.

If you don’t have any ready-made stock, you can always boil up a pan of vegetable cuttings while you’re roasting the tomatoes.

If not, just switch the vegetable stock for water.

Adding Plant Milk

Choose any type of unsweetened plant milk that you normally prefer.

If you don’t have any plant milk in your home, you can use 1.5 cups of cashews instead.

Either soak the cashews in boiling water for 15 minutes to soften them and then discard the water before adding the cashews to the soup and cooking until soft enough to blend.

Or, if you don’t want the extra hassle of soaking first, you can also add the raw cashews straight to the pan and cook them until soft through before blending.

It will take a little bit longer time but a little bit less hands-on work.

Top Tip for Reusing Leftover Tomato Soup

Be sure to make extra soup so that you have some leftovers in the fridge for the next day. Then, remove the fridge and dilute it with extra veggie broth and/or unsweetened plant milk.

Meanwhile, the day before, eat a delicious meal of air fried vegetables with tofu, making sure to also make more than you need and keeping the leftovers for your day two of tomato soup.

Add the leftover air fried veggies and tofu to the diluted tomato soup. Break in some wholemeal rice noodles and heat through for 5-6 minutes or until the noodles are cooked.

You now have a complete meal in a bowl, and instant meal for day two of tomato soup.
