1-Getting started with this scalloped potato gratin: Begin by preheating your oven to 425°F, which helps ensure the potatoes turn out tender and flavorful. This recipe’s lighter take means you can enjoy it without guilt, serving up to 7 people with each cup packed full of taste.

2-First, prepare your potatoes: peeling and slicing 6 medium Yukon gold potatoes to 1/8-inch thick. This step is crucial for achieving those perfect creamy layers. Mix in 2 tablespoons of melted light butter, salt, fresh pepper, and 1/2 teaspoon of garlic powder to season the slices evenly.

3-Next, layer the potatoes in an 11 x 7-inch baking dish, adding 3 ounces of shredded reduced-fat Cheddar cheese between the layers. For the sauce, bring 1 cup of fat-free milk, 1 bay leaf, 2 teaspoons of thyme, and a pinch of freshly grated nutmeg to a boil in a small pot. Pour this mixture over the potatoes to create that light buttery sauce.

4-Baking and Finishing Touches: Once assembled, bake the dish uncovered at 425°F for 45 to 50 minutes until the potatoes are tender. The total cook time is about 1 hour, with prep taking roughly 15 minutes, so the whole process fits into a busy day. Let it cool a bit after baking to make serving easier.
