I love October . . .  it is in October that my taste palate turns to the colour orange and I just want to eat my fill of winter squash and pumpkins, carrots and sweet potatoes.  I don't crave these things in July and August,  or even September  . . . but once the calendar page flips over to October, I can't seem to get enough of them and I start incorporating them into whatever I can.

I know that Americans mostly like their sweet potatoes mashed and coated with marshmallows, brown sugar and nuts . . .  and they are rather good that way . . .  but I am more in love with the savoury approach when it comes to sweet potatoes.

Sweet potatoes lend themselves beautifully to savoury dishes.  I often bake them and just mash them with some garlic and parmesan cheese. They are gorgeous done that way.   Sometimes I do sweet potato wedges . . .  just like regular potato wedges, except with sweet potatoes  I toss them with some olive oil, herbs, garlic and seasoning and roast them in a hot oven until they are nicely crisped and caramelized.  So good.

They really shine in dishes like this lovely two potato gratin which I have prepared here today . . . layers of tender white potato, chopped onion,  sweet potatoes and several kinds of cheese.  There is no butter  . . .  you don't need butter with the cheese.

There is no cream . . .  once again the cheese adds a richness that cream often adds . . .  it is thickened merely with a bit of flour between the layers . . .  it's only seasoning is a bit of salt and pepper . . .  and the moisture comes from ordinary milk.

Altogether everything melds into a beautiful dish that is simple and easy to make . . .  and goes so very well with most flavours.  We had it with some pork chops . . .  but it would be equally at home with chicken, or fish . . .  lamb, or even on it's own.  In all truth I could sit down to just a plate of this quite, quite happily.

  1. Marie: I don't happen to have any sweet potatoes, but wonder if I could just use the ones I have on hand because this looks yummy!

  2. Thanks MOnique! You aren't wrong! haha xx

    Sharon, I think you could quite happily use all white potatoes if you wish. T'would be just as delish! xx

  3. I love potato gratin! and this look georgeous Marie:)

  4. This looks yummy Marie! Some Americans do like a sweet potato dish mashed with brown sugar, marshmallows and nuts for the Thanksgiving holiday (and others wouldn't touch it) but not usually for an everyday dish. I love them baked with a pat of butter on them as a side dish or even for my lunch. They are delicious and really good health wise. Hugs! xoxo

  5. Thanks Gloria!! YOU make me smile! xx

    Val, I love to roast them in their skins and then slip them out and enjoy them just like that, with nothing else. well, maybe some coarse black pepper. Hugs back! xoxo
