How to Prepare Cheesy Leek and Celeriac-Potato Gratin [Vegan]

Pre-heat the oven to 180ºC (356)ºF).
Parboil the potatoes, leeks and celeriac (i.e. boil for 10 minutes) in a large heavy-bottomed pot, then drain.
If it is ovenproof, you may use the same pot to bake the vegetables in the oven. In that case, grease it with some vegan butter. Set aside for now.
To prepare the sauce, place a small saucepan over medium heat. Melt 1 tsp vegan butter and lightly fry to garlic. Throw in the herbs and nutmeg then pour in the soya milk, all the while stirring continuously. Finally add in 4 tbsp of nutritional yeast. Keep stirring while the sauce reduces; you will need to simmer the sauce for about fifteen minutes. Take off the heat.
Place the parboiled vegetables in the greased heavy-bottomed dish, cover with the sauce, sprinkle over the breadcrumbs and 1 tbsp nutritional yeast, then bake for 30 minutes. If you wish to incorporate vegan cheese cubes, stir them in with the vegetables.

Notes

Notes: * If you wish to make this recipe gluten-free, use gluten-free bread for the breadcrumb topping. * I’m not too specific on the potatoes. Use any that you have on hand, except sweet potatoes, as I don’t think they would taste too great with the leeks and cheese (not to mention the horribly clashing colour). Keep an eye on your potatoes while they’re cooking; different sorts may need different cooking times before they are tender.
