½medium yellow or white onionsliced into thin rings
¾teaspoonsalt
½teaspoondried thyme
1 ¾cupshredded gruyere cheese
¼cupunsalted buttercut into small cubes
fresh cracked black pepper
2 ¼cup1% or 2% milk
6tablespoonsall-purpose flour
Instructions
Preheat the oven to 375 degrees Fahrenheit.
Spray an 8 x 8-inch baking dish with non-stick cooking spray or grease with butter. Layer ⅓ of the potatoes in the pan. Sprinkle with ⅓ of the onions, salt, dried thyme, gruyere cheese, butter, and freshly cracked pepper. Repeat 2 times, continuing to layer ⅓ of the ingredients each time.
In a large mixing bowl, vigorously whisk together the milk and all-purpose flour until a frothy mixture forms and all of the flour has dissolved in the milk.
Immediately pour the milk mixture over the layered potatoes in the baking pan.
Cover the baking dish with aluminum foil or the baking pan lid. Bake for 40 minutes.
Remove the foil or lid from the baking dish and bake for 30-35 minutes more, or until the cheese is golden brown and the potatoes are cooked through.
Rest the potatoes at room temperature for 5-10 minutes, or until the cheese sauce has thickened up. Serve hot!
Notes
1. For best results, let the sweet potatoes rest for 5-10 minutes before serving. This will help the cheese sauce thicken up. To retain the heat while resting, cover the potatoes with aluminum foil or the baking pan lid. 2. Store leftovers covered in the refrigerator for 4-5 days. They do not freeze well.
