Potato & Rutabaga Gratin with Blue Cheese

RATE IT

Serves six to eight.

While rutabagas taste and behave a lot like turnips, they’re nuttier, less peppery, and creamier, which is why I prefer them in gratins. The easiest way to peel a rutabaga— especially a waxed one—is with a sharp paring knife. Use a very sharp knife or a mandoline to slice the rutabaga and potatoes.

  • 3 cups heavy cream
  • 2 cloves garlic, peeled and smashed
  • 1 bay leaf
  • 2 hearty sprigs fresh thyme
  • Pinch freshly grated nutmeg
  • 3 Tbs. melted unsalted butter; more butter for the foil
  • 1 medium rutabaga (about 1-1/2 lb.), peeled, quartered, and very thinly sliced
  • 2 to 3 russet potatoes (about 1-1/2 lb.), peeled and very thinly sliced
  • Salt and freshly ground black pepper
  • 4 oz. blue cheese, such as Maytag, Roquefort, or Bleu d’Auvergne, crumbled
  • 3 Tbs. fresh breadcrumbs, toasted (see How to make fresh breadcrumbs for instructions)
Tip:
For the neatest servings, let the gratin sit for at least 10 min. before slicing.

Heat the oven to 375°F. Rinse a small saucepan in cold water (this will make the pan easier to clean later), add-the cream, garlic, bay leaf, thyme, and nutmeg. Bring to just below a simmer over medium heat, remove from the heat, cover, and set aside to infuse for about 30 min.

Brush a large gratin dish or 3-qt. flameproof casserole dish with a little of the melted butter. Arrange half of the rutabaga slices in the bottom of the dish, followed by half of the potato slices. Season with salt and pepper. Dot the surface with the blue cheese. Continue with another layer of rutabaga slices and a final layer of potatoes. Season the top with salt and pepper. Strain the seasoned cream over the top. In a small bowl, combine the breadcrumbs with the remaining melted butter and sprinkle over the top. Butter the dull side of a large sheet of foil and cover the gratin. Bake for 40 min., remove the foil, and continue to bake until the top is browned, the sides are bubbly, and the potatoes are tender when pierced, another 30 to 40 min. Let sit for 10 min. before serving.

I bought a rutabaga the other night, simply because I had never cooked one before. I have to say this is the best gratin I have ever made, thanks so much for the recipe.
