One is a student, and one does not have a lot of money, although one is fortunate to have more than others and counts her blessings daily. But one had decided a while ago to eat cheaply whenever possible; one signed up to receive a most cost-effective delivery of seasonal, local produce every week. One resolved to eat this produce, because it was cheap and good for her, even if she did not like them.

One abhors leeks. And leeks she receives every damn week.

What could possibly mask the ghastly, sickening flavor of these obscenely long and ugly onions? How could I bring myself to swallow this stringy, fibrous vegetable? Only one answer came to mind.

Cheesy Leek and Celeriac-Potato Gratin

This Recipe is :





  • 500 g (1.1lbs) waxy potatoes (such as Maris Piper), cut into 1 cm (1/2″) chunks
  • 1 head of celeriac, peeled and chopped into 1 cm (1/2″) chunks
  • 3 leeks, washed and sliced into 1 cm (1/2″) medallions
  • 50 g (1.76 oz) vegan cheese (optional)
  • 1 tsp vegan butter + extra for greasing
  • 4-5 tbsp nutritional yeast
  • 500 ml (2 cups) soya milk
  • 2 cloves of garlic, peeled and crushed
  • 1/4 tsp grated nutmeg
  • 1/2 tsp dried sage
  • 1/2 tsp dried thyme
  • 20 g (1/4 cup) breadcrumbs


  1. Pre-heat the oven to 180ºC (356)ºF).
  2. Parboil the potatoes, leeks and celeriac (i.e. boil for 10 minutes) in a large heavy-bottomed pot, then drain.
  3. 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.
  4. 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.
  5. 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.


* 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.





After turning vegan, I discovered a particular talent for baking delicious cruelty-free cakes and cookies. It was then that my friends named me ‘The Vegan Cookie Fairy’ and my blog was born. I find happiness in preparing and eating food that is good for my body and soul — but cats and yoga help, too.
