Recipe adapted from Delicious Magazine
250g sourdough bread, torn into 1/2/2cm pieces
3 tbsp olive oil
10 fresh thyme sprigs
2 long sprigs fresh rosemary
2 banana shallots, finely sliced
6-8 scallions, trimmed and cut into thirds
1 tbsp plain flour
300ml heavy whipping cream
350ml whole milk
Pinch freshly grated nutmeg
500g parsnips, quartered and any woody cores removed, cut into 1/4″/1cm chunks
300g Yukon Gold potatoes (halved if large), cut into 1/4″ /1cm slices
6oz Gruyère or mature cheddar, coarsely grated
You will need a 1.4 liter baking dish
1/ Heat the oven to 400F/200°C/180°C fan/gas 6.
Put the sourdough pieces on a large baking tray, then toss with 2 tbsp olive oil, the leaves from 4 thyme sprigs and the rosemary leaves, chopped. Season with salt and pepper, then bake for 10 minutes until golden and crisp. Set aside.
Turn down the oven to 350F/180°C/160°C fan/gas 4.
2/ Heat the remaining oil in a large pan or casserole over a medium heat, then cook the shallots and spring onions for 7-8 minutes until soft. Add the flour and stir for 3 minutes, then turn the heat to low-medium and add the double cream, milk, nutmeg and 2 thyme sprigs. Heat until just steaming. Add the parsnips and potatoes and cook for 10 minutes until softening. Season with salt and pepper, remove from the heat (discard any woody thyme sprigs), then stir in a third of the cheese.
3/ Pour the vegetables and creamy liquid into the prepared baking dish, sprinkle half the remaining cheese on top, then bake for 30 minutes. Scatter the croutons on top of the gratin with the rest of the thyme and cheese, then bake for 15-20 minutes more until the top is golden brown and the gratin is bubbling. Serve with a sharply dressed green salad.

You could use other crusty breads such as ciabatta or baguette for the topping.
Prepare the gratin to the end of step 2 a few hours in advance, cool and keep in the fridge until ready to bake.
Store the herby, baked sourdough croutons in a sealed container.
