Ingredients

1 pound parsnips, peeled

1 pound sweet potato, peeled

1 pound celery root, peeled

1 pound russet potatoes, peeled

1 cup heavy cream

1/2 cup low-sodium chicken stock

1 teaspoon dried tarragon

1 tablespoon minced garlic

6 ounces Gorgonzola cheese, crumbled

1 teaspoon salt

2 teaspoons freshly ground black pepper

Special equipment: a 1 1/4 quart oval gratin dish

Directions

  1. Preheat oven to 400 degrees F with rack in middle.
  2. Slice vegetables into 1/4-inch thick slices. In a large bowl, toss vegetables with cream, stock, tarragon and salt and pepper, garlic and Gorgonzola. Put into prepared gratin dish. Cover loosely with heavy duty foil. Bake for 1 hour, until vegetables are fork tender. If tender, remove foil, leave dish on middle rack and turn broiler on high.
