Author Notes

I’m as fond as anyone of a simple steak frites dinner. Sometimes I make a Béarnaise sauce, but sometimes, especially if the wine is good, it’s enough to serve the steak with just a spoonful of Dijon mustard. I always have some greens to go with it, steamed haricots verts or spinach or just a simple salad. Sometimes I have a small steak and lots of spinach. That’s when my husband thinks I’ve read some article and I’m suddenly on a diet. But that would never happen. It’s just that sometimes French fries are…well, not exactly what I am looking for, and then I need an alternative. If it’s pumpkin season, this gratin is one of the best. Steak pairs really well with roasted squash, and this gratin version makes the duo even more satisfying. —Mimi Thorisson
