Scalloped Root Veggies

Preheat oven to 375 degrees F. Coat a 1 1/2-quart oval baking dish or casserole with cooking spray. Arrange sliced celery root and parsnips in the prepared baking dish.

In a small saucepan combine milk, butter, the snipped thyme, the garlic, and pepper; heat over low heat just until simmering. Pour over vegetables in baking dish.

Bake, covered, 40 minutes. Meanwhile, in a small bowl stir together 2 tablespoons of the Parmesan cheese and the flour. Stir flour mixture into vegetables. Sprinkle with the remaining 3 tablespoons Parmesan cheese. Bake, uncovered, about 15 minutes more or until vegetables are tender and top is lightly browned. Let stand 10 minutes before serving. If desired, garnish with additional fresh thyme.
