Ingredients
- 6 strips bacon,diced 
- 1 large onion, chopped 
- 3 tablespoons butter 
- 4 tablespoons all-purpose
     flour 
- 2 cups milk 
- 1 teaspoon salt 
- ¼ teaspoon ground black pepper dash ground
     nutmeg, optional 
- 2 pounds russet potatoes, peeled and sliced about
     ¼-inch thick 
Directions
- Heat the oven to 350 F. 
- Generously butter a 2-quart baking dish. 
- In a deep skillet or saute pan, cook the bacon
     until just crisp; remove to paper towels and set aside to drain. 
- Leave about 2 tablespoons of bacon drippings in
     the skillet and add 3 tablespoons of butter. Saute the onion until
     softened. Add the flour and continue cooking, stirring, for about 1
     minute. Gradually stir in the milk. Cook, stirring, until the sauce is
     thickened. 
- Stir in the salt, pepper, and nutmeg, if using.
     Stir in the cooked bacon. 
- Layer half of the potato slices in the prepared
     baking dish. Spoon half of the sauce mixture over the potatoes. Top with
     the remaining potatoes. Spoon the remaining sauce over all. Cover the
     casserole tightly with foil and bake for 1 hour. Remove the foil, return
     to the oven, and bake for about 20 to 30 minutes longer, or until the
     potato slices are fork-tender. 
- Serves 5 to 6. 
Tips and Variations 
- Add 1 cup of shredded cheddar cheese to the sauce or top the casserole with the cheese when the potatoes are tender and almost done. Continue baking until the cheese has melted.
