Potato and Butternut Squash Gratin; the day after

Gratins have gotten a bit of a bad reputation in the US.

This could be because they usually are drowned in heavy cream, have lots of butter and way too much cheese.

Not that there’s anything wrong with that – if you can limit your serving size to a teaspoon and don’t want to taste the vegetables.

We prefer a more balanced dish.

And I long ago realized that a bit of chicken stock to replace the cream and a strong cheese rather than bland makes a wonderful, reasonable gratin that I can enjoy without an extra workout the next day.

This would be perfect with leftovers from turkey dinner. It’s a very autumnal dish with the butternut squash and fresh sage.

I use a mandolin to slice the potatoes and squash but a sharp knife will work as well. They shouldn’t be ‘paper thin’ but close.

  • 12oz (360gr) butternut squash, the ‘neck’ end

Butternut Squash and Potato Gratin


  • Heat oil in a medium skillet over medium-high heat.
  • Add onions, garlic and sauté until tender, 7 – 10 minutes
  • Remove from heat and set aside.
  • In a baking dish just large enough to hold ingredients lay 1/2 of the potatoes, 1/2 of the squash, all of the sautéed onions and all of the sage leaves. Finish with the remaining potatoes topped with the remaining squash.
  • Sprinkle the nutmeg over the top.
  • Pour the stock over all, cover with foil and bake at 400F (200C) for 45 minutes.
  • Remove from oven and remove foil
  • Top with cheese.
  • Return to oven and bake, uncovered, for 15 minutes longer..
  • Remove, let rest 5 minutes, then serve.

Note: You could also bake longer in a slower oven – 90 minutes at 350F (180C)

Speaking of Turkey Day, er, I mean Thanksgiving….

We haven’t celebrated Thanksgiving since we left Andorra – and there it was the day of the ‘End-of-Season’ tournament for our golfing group…. More exercise and no naps.

Turkeys don’t start showing up in the supermarkets here until much closer to Christmas and cranberries have only made a recent appearance. Since I can’t get the proper food, family isn’t going to pop over for turkey dinner and the locals don’t really understand the holiday (and they work), we’ve gotten into the habit of skipping it altogether.

I do miss the leftovers, though… (The French also don’t understand the concept of leftovers…. Why would one make too much food only to have to eat the same thing again the next day?)

This would be great with leftovers – if you should be so lucky.

Bon weekend!

  1. This gratin can save our attitude about gratin. In the States, I remember a sort of crumbled bread over green beans. At least those cooks had a broiler, which we don’t have now.

    The notion of stronger cheese is intriguing; will be trying that soon.

    About Thanksgiving, there is no hope in this household. Neither of us were fortunate enough to grow up with turkey, or unfortunate enough to have to cook turkey under pressure with guests and family inbound.

    When we returned to Europe as adults, we did get the day off as Yanks, but all the restos were open so we got used to going out for lunch instead. It was a treat to be off on a Thursday for lunch. Eventually, we settled on preferring a certain style of food, over the long years of marriage. Yesterday, she had lamb curry and I had beef curry. We gave thanks.

  2. I love leftovers too. Pizza for breakfast is a favourite with some of my children but leftover desserts for breakfast like trifle or pavlova are wonderful and naughty !!

  3. Dan, I rather liked celebrating with the golfers – always a good Catalan dinner with lots of wine. To be honest, I don’t really miss the big production – and it was a BIG production when we lived in the US.Curry sounds good…. We had Spinach Burgers with Mushroom Red Wine Sauce…. also good

    kate, pizza for breakfast – yum…. And I love sweets for breakfast – hot chocolate and Christmas cookies – soon
