Instructions

Fry the Leek
1

Preheat your oven to 220°C/200°C fan/gas mark 7 for the ciabatta

Trim the root and dark green leafy part from the leek and discard. Halve lengthways, then thinly slice. Peel and grate the garlic (or use a garlic press).

Heat a drizzle of oil in a large saucepan on medium-high heat.

Once hot, add the leek and season with salt and pepper. Cook the leek until softened, 4-6 mins, stirring occasionally.

Make the Garlic Bread
2

Meanwhile, halve the ciabatta and lay onto a baking tray, cut-side up.

Spread over half the garlic and drizzle with the olive oil for the garlic bread (see pantry for amount). Set aside.

Drain and rinse the butter beans in a sieve.

Stir in the Beans
3

Stir the remaining garlic and cider vinegar into the leek. Fry for 1 min. Add the sugar (see pantry for amount) and cook until caramelised, 1-2 mins more.

Add the butter beans to the pan and roughly mash half of them using a potato masher or the back of a fork.

Stir in the vegetable stock paste and water for the soup (see pantry for amount).

Bring to the boil, then simmer until the sauce has thickened slightly, 4-5 mins. 

Simmer the Soup
4

Bake the garlic bread on the top shelf of your oven until golden, 4-5 mins.

Meanwhile, stir the creme fraiche into the soup. Add spinach to the pan a handful at a time until wilted and piping hot, 1-2 mins.

Cheese Time
5

When everything's ready, stir half the cheese into the soup

Taste the soup and season with salt and pepper if needed. 

Serve
6

Divide the soup between your bowls.

Drizzle over the pesto and top with the remaining cheese and chilli flakes (add less if you'd prefer things milder). 

Serve the garlic bread on the side.
