Preparation

Step 1

1.Preheat oven to 350º. Spray a 13x9-inch baking dish with nonstick cooking spray.

2.In a large skillet, melt butter over medium heat. Add onions and cook, stirring occasionally, for 1 hour or until golden brown. (Monitor the onions closely during the end of the cooking time because they can burn easily.)

3.In a small bowl, whisk flour into ½ cup evaporated milk. In a medium saucepan, combine remaining milk, chicken broth, pepper, and salt. Bring to a boil over medium-high heat. Whisk in flour mixture; reduce heat to medium, and cook, whisking constantly, for 5 minutes or until thick. Stir in thyme leaves.

4.Arrange one-fourth of potato slices in the bottom of the baking dish. Spread one-fourth milk mixture over potatoes. Sprinkle one-fourth onions over sauce. Repeat layers 3 more times. Sprinkle cheese on top of potatoes before baking. Cover with aluminum foil.

5.Bake for 30 minutes. Uncover and bake 45 minutes longer or until casserole is bubbly and potatoes are tender. Garnish with thyme, if desired.
