As much as I love tomato soup I’m often horrified by the cost of making it at home. It’s common for recipes to call for a minimum of 1.5kg tomatoes for a few portions, that’s pretty darn expensive to buy, and even when I have a glut in my garden I’ll be hard pressed to provide that more than once a season.
So to satisfy the penny pincher in me (and to acknowledge that for yet another year in a row there’ll be little to no sunshine and my tomato harvest is likely to be nil) I’ve created a tomato soup that delivers all the flavour for a fraction of the cost, the tomatoes being bulked out a little with peppers and carrots, and a shot of concentrated tomato puree gives an extra boost of tomatoeyness. The basil oil isn’t strictly necessary, but I do think a homemade soup deserves that little extra dressing up, and it means you can make this in the winter (or our ‘summer’ equivalent), with hothouse-grown tomatoes, and still feel like you’re in the Provençal sunshine.
Roasted tomato & pepper soup with basil oil
500g cherry tomatoes
2 red peppers, quartered and deseeded
Half a red chilli (in the piece, not chopped)
3 small carrots, peeled
a small knob of butter
1 small red onion, peeled and finely diced
2 garlic cloves, bruised and peeled
pinch of celery salt
3 tbsp concentrated tomato puree
500ml vegetable stock
For the basil oil
15g basil leaves
Toss the tomatoes, peppers and chilli in a tiny drop of oil (just enough to stop them sticking), then roast at 200˚C/Gas 6 for 40-45 minutes. Remove the peppers to a bowl, cover with clingfilm and leave to cool before skinning. If you can be bothered, pinch the skins from the tomatoes too, but don’t be too fastidious about it.
Finely grate the carrots (use the finest side on a box grater, or a microplane), then sweat in the butter with the onion, bruised garlic, celery salt and tomato puree until meltingly tender. Add the roasted tomatoes, skinned peppers and the chilli, plus the vegetable stock. Bring to the boil, simmer for just a minute or two, then blitz and season to taste.
For the basil puree, whizz the basil leaves with a pinch of salt and just enough olive oil to form a smooth paste (using a stick blender or mini processor). Serve the soup drizzled with the oil.
