Ingredients

• 2 lbs Yukon Gold potatoes
• 2 cups Fat-free milk
• 1 cup Low-fat mozzarella cheese, shredded
• 2 tablespoons Parmesan cheese, grated
• 2 tablespoons Cornstarch
• 2 cloves Garlic, minced
• 1 teaspoon Fresh thyme, chopped
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 0.25 teaspoon Nutmeg
• 1 as needed Cooking spray

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Lightly grease a 9x13-inch baking dish with cooking spray and set aside.

Step 3

Peel and thinly slice the Yukon Gold potatoes, aiming for uniform slices about 1/8-inch thick to ensure even cooking.

Step 4

In a medium saucepan, combine the fat-free milk, minced garlic, salt, black pepper, nutmeg, and freshly chopped thyme. Heat over medium heat until warm but not boiling.

Step 5

In a small bowl, mix the cornstarch with a couple of tablespoons of the warm milk mixture to create a slurry, then slowly whisk it back into the saucepan. Continue to stir as the mixture thickens slightly.

Step 6

Remove the milk mixture from heat and stir in the shredded low-fat mozzarella cheese until melted and integrated.

Step 7

Arrange half of the potato slices evenly in the prepared baking dish, overlapping them slightly. Pour half of the milk-cheese mixture over the potatoes, spreading it gently.

Step 8

Layer the remaining half of the potato slices over the first layer and pour the remaining milk-cheese mixture evenly over the top.

Step 9

Sprinkle the grated Parmesan cheese on top.

Step 10

Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes.

Step 11

Remove the foil and continue to bake uncovered for an additional 25 to 30 minutes, or until the top is golden brown and the potatoes are tender when pierced with a fork.

Step 12

Allow the gratin to cool for about 10 minutes before serving. This will help it set and make it easier to slice.

Step 13

Serve warm, garnished with additional thyme if desired.
