By curly

Ingredients

• 3 baking potatoes, peeled and cut in half
• 1/4 cup butter
• 1/4 cup chopped leeks
• 1 clove garlic, minced
• 1/4 cup flour
• 2 cups milk
• 1 egg, beaten
• 1 cup grated Gruyere cheese

Preparation

Step 1

Simmer potatoes in boiling salted water just until tender, 20 to 30 minutes. Drain and cool.

In medium saucepan, heat butter until melted. Add leeks and garlic and saute until tender. Remove from heat and stir in flour. Gradually stir in milk. Heat to simmering, stirring occasionally. Simmer, stirring constantly until slightly thickened, about 5 minutes. Add a little hot milk to egg and mix well. Then stir egg combination back into sauce. Heat and stir just until slightly thickened. Stir in 1/2 cup cheese.

Cut cooled potatoes crosswise into 1/2-inch slices. Arrange in bottom of 9 inch round baking dish. Pour sauce evenly over potatoes in baking dish. Sprinkle over remaining 1/2 cup cheese. Put on baking sheet to catch any drips. Bake at 375 degrees about 30 minutes or until golden brown and hot in center.
