Root Vegetable Gratin

Yield 6 servings
Sometimes forgotten vegetables like winter squash, celeriac and leeks, become family favorites, when they're layered with potatoes and baked to perfection in a delicious cream sauce.

Ingredients

  • 3 tablespoons unsalted butter, softened
  • 1 small butternut squash (about 1 1/2 pounds), peeled and thinly sliced (about 4 cups)
  • 1 pound red potato, peeled and thinly sliced* (about 3 cups)
  • 1 bulb celery root (celeriac), about 1 pound, peeled, cut in half and thinly sliced (about 1 cup)
  • 1 bunch leek, washed well, white part only, thinly sliced (about 1 cup)
  • 1 3/4 cups Swanson® Vegetable Broth (Regular or Certified Organic)
  • 1/2 cup heavy cream
  • 1 teaspoon minced fresh thyme leaves
  • 1/2 teaspoon ground nutmeg
  • 1/3 cup grated Parmesan cheese

How to Make It

  1. Heat the oven to 400°F. Spread the butter in a 13 x 9 x 2-inch baking dish. Add the squash, potatoes, celery root and leeks to the prepared dish.

    Heat the broth, cream, thyme and nutmeg in a 2-quart saucepan over medium heat to a boil. Season to taste.

    Pour the broth mixture over the vegetables and toss to coat.

    Bake for 25 minutes. Reduce the temperature to 350°F and bake for 40 minutes more, or until golden brown and the vegetables are tender. (If the vegetables are browning too fast in the first 25 minutes, cover the dish loosely with foil.)

    Sprinkle with the cheese. Let stand for 10 minutes.

    *Time-Saving Tip: Use a Japanese mandoline to slice the potatoes to an 1/8-inch thickness.
