Donna Hay's Sweet Potato, Leek and Sage Gratin

Here's my second Donna Hay recipe and it's a perfect potato dish for the holidays, although my photograph below doesn't look very Christmasy. I gave this a test run ahead of the holidays and loved the dish so much, I intend to make it for Christmas Eve dinner.
Use your mandolin to slice the potatoes...if you don't have one, slice thinly. I used fontina as it's such a nice melting cheese. Wonder how gruyere would taste?

Sweet Potato, Leek and Sage Gratin

Donna Hay, Issue 60

40g (about 3 tablespoons) butter
4 leeks, cleaned and sliced
2 cloves garlic, crushed
sea salt and cracked black pepper
800g ( about 1 3/4 pounds; I used 2 large.) sweet potato, peeled and thinly sliced
800g (about 1 3/4 pounds; I used 2 large Idahos, they worked fine.) Desiree (waxy) potatoes, peeled and thinly sliced
2 tablespoons olive oil
1 cup sage leaves, torn in pieces
300g fontina or cheddar cheese, sliced

Preheat oven to 400 degrees F. 
Melt the butter in a non-stick frying pan over medium heat. Add the leek and garlic, salt and pepper and cook for 5 minutes or until softened. Place the sweet potato, potato, oil and salt and pepper in a bowl and toss to combine. Layer the sweet potato, potato, leek, sage and cheese in a 10 by 13-inch baking pan lined with non-stick baking paper, finishing with a layer of cheese. Cover loosely with aluminum foil and bake for 30 minutes. Remove foil and bake for a further 30 minutes or until golden and cooked through. Serves 6-8.


  1. Potatoes and cheese♥ And sage..I know I would love this..unlike many I even hate the look of poutine..which is curd cheese,fries and sauce..but this kind of taters and cheese? Yes.
    Happy Holidays to you! You''ll have fun w/ your daughter:)

  2. I too love Donna Hays recipes! This is a delicious looking gratin.
    Have a wonderful holiday season, Barbara!

  3. I am working on my Christmas Eve menu as well! You gratin should be a hit! Best wishes for a wonderful holiday season Barbara!

  4. I think Gruyere would taste wonderful in this gratin. It sounds so good, Barbara, and if I were making Christmas dinner I'd have it on the table. I think I'll make it just for us this week :)

  5. It sounds wonderful Barbara! Merry Christmas.

  6. oh, gruyere would be amazing! this is a fantastic recipe, definitely reason enough for me to break out my mandoline and potentially slice off part of my hand. :)

  7. The mix of potatoes sounds so good! So does the sage. I want sage on everything right now. Merry Christmas, Barbara!
