Cheesy au Gratin Potatoes

1. Preheat Oven

Preheat your oven to 350°F.

2. Combine Cheeses and Cornstarch

In a large bowl, combine the shredded sharp cheddar cheese, Monterey Jack cheese, and grated Parmesan cheese with the cornstarch. Toss together until the mixture is evenly coated.

3. Layer Potatoes and Season

Take a large gratin dish and layer half of the potato slices in the dish, overlapping slightly. Sprinkle about 1 cup of the cheese mixture evenly over the potatoes. Season with 0.75 teaspoons of salt and 0.25 teaspoons of pepper. Layer the remaining potato slices on top, and season again with another 0.75 teaspoons of salt and 0.25 teaspoons of pepper.

4. Add Cream and Broth

In a large measuring cup, combine the heavy cream with the low-sodium chicken broth. Pour this mixture over the layered potatoes.

5. Bake

Sprinkle the remaining cheese mixture evenly over the top of the potatoes. Place the gratin dish in the preheated oven and bake for 75 to 90 minutes until the top is golden brown and the potatoes are tender.

6. Cool and Serve

Once out of the oven, let the dish cool for about 10 minutes before serving.
