During the autumn I often serve this roasted root vegetable gratin as a vegetarian main course and add a few slices of apple when roasting the vegetables. It is also delicious wth roasted pork or lamb for the « where’s the meat brigade » in my family !!


200 g potato, peeled & cut into bite-size chunks

200 g turnip, peeled and cut into bite sized chunks

200 g carrot, peeled and cut into bite sized chunks

200 g celeriac, peeled and cut into bite sized chunks

200 g parsnips, peeled and cut into bite sized chunks

2 medium onions, sliced

1 garlic clove, crushed

3 tbsp sunflower oil

3 tbsp wholegrain mustard

2 tbsp honey

1 tbsp parsley, chopped

1 tbsp rosemary, chopped

100 ml cream

For the topping

120 g breadcrumbs

70 g hazelnuts, toasted and chopped

4 tbsp butter, melted

4 tbsp gruyere  cheese, grated


  1. Preheat the oven to 200C/Fan 180/Gas 6.
  2. Combine the potatoes, turnips, carrots, celeriac, parsnips, onions and garlic in a large roasting dish.
  3. Whisk together the oil, mustard and honey and pour over the vegetables. Mix well. Sprinkle the parsley and rosemary over the top. Season with salt and pepper.
  4. Cover with tin foil and roast for about 50 minutes. Remove the foil cover, add the cream and stir well.
  5. Mix all ingredients for the topping and sprinkle over the roasted vegetables. Return to the oven for 20 minutes until golden brown.

Catherine’s Top Tip:

Add 2tsp harissa to the vegetables when roasting for a more Moroccan/Tunisian flavour.
