Ingredients
¼ cup chopped onion
2 Tbsp. butter
2 Tbsp. flour
1 ¼ cup milk
¼ tsp salt
1 cup shredded cheese, divided
3 medium potatoes, peeled and thinly sliced (3 cups)
Method
In a sauce pan, cook onion in butter till tender. Stir in flour and salt. Add milk all at once. Cook and stir until thickened and bubbly.
Remove from heat. Mix in ¾ cup of cheese.
Place half the sliced potatoes in a greased 1 quart dish. Cover with half the sauce. Repeat layers. Top with remaining ¼ cup of cheese.
Bake covered at 350 degrees for 35 minutes. Uncover and bake 30 minutes more or till potatoes are tender.
Let stand 5 minutes.
Serves 4. (If you don’t want to use the cheese and just have plain scalloped potatoes, omit the cheese and increase the salt to ½ tsp.)
