Scalloped Potatoes with Ham

6 tablespoons butter or margarine, divided
1/4 cup all-purpose flour
1 teaspoon dried parsley flakes
1 teaspoon salt
1/2 teaspoon dried thyme
1/4 teaspoon pepper
3 cups milk
6 cups thinly sliced peeled potatoes
1-1/2 cups chopped fully cooked ham
1 small onion, grated

In a saucepan, melt 4 tablespoons butter. Stir in flour, parsley, salt, thyme and pepper until smooth. Gradually add milk; bring to a boil. Cook and stir for 2 minutes.

Combine potatoes, ham and onion; place half in a greased 2-1/2-qt. baking dish. Top with half of the sauce; repeat layers. Cover and bake at 375° for 65-75 minutes or until potatoes are almost tender.

Dot with remaining butter. Bake, uncovered, 15-20 minutes longer or until potatoes are tender. Makes 4 servings.
