Cheesy Au Gratin Potatoes
Description
This gratin begins by coating shredded cheeses with cornstarch to prevent clumping. Thin slices of peeled russet potatoes (about 1/8 inch thick) are arranged in a baking dish in overlapping layers. Half of the cheese mixture and seasoning are sprinkled between layers, with the remaining cheese and seasoning layered on top. A mixture of heavy cream and low-sodium chicken broth is poured over the potatoes, providing moisture and richness as it bakes.
The dish is baked at 350°F until the potatoes are tender and the top is golden brown, typically 75 to 85 minutes. The cornstarch in the cheese helps create a smooth cheese sauce, while the layered potatoes absorb the creamy mixture for a tender texture. The combination of cheddar, Monterey Jack, and Parmesan cheeses offers a balance of sharpness, creaminess, and nutty flavor.
Serving after a 10-minute rest allows the gratin to set slightly for easier portioning. Uniformly thin potato slices are crucial for even cooking and texture, making a mandoline or slicing disk helpful. This dish makes a hearty side suitable for many meals.
Ingredients
- 1 ¼ cups cheddar cheese shredded sharp
- 1 ¼ cups Monterey jack cheese shredded
- ½ cup Parmesan Cheese grated
- 2 teaspoons cornstarch
- 3 pounds russet potato peeled and sliced 1/8-inch thick
- salt
- black pepper
- ¾ cup heavy cream
- ½ cup chicken broth low-sodium
Instructions
- Preheat the oven to 350 degrees and adjust an oven rack to the middle position. In a large bowl, toss the cheeses and cornstarch together until evenly coated.
- In a large gratin dish (about a 2- to 3-quart dish), shingle half of the potatoes. Sprinkle the potatoes evenly with 1 1/2 cups of the cheese mixture, 1/2 teaspoon salt, and 1/4 teaspoon pepper. Top with the remaining potatoes, shingling them neatly and evenly. Sprinkle another 1/2 teaspoon salt and 1/4 teaspoon pepper evenly over the top.
- Combine the cream and the broth in a large measuring cup and pour the mixture over the potatoes. Top with the remaining cheese mixture and bake until golden brown and a fork inserted into the center slides in easily with little resistance, 75 to 85 minutes. Let the potatoes cool for 10 minutes. Serve.
Notes
- Uniform potato slices about 1/8-inch thick ensure even cooking; use a mandoline or food processor slicing disk for best results.
- The cheese is coated with cornstarch to prevent clumping and create a smooth sauce.
- Let the gratin rest 10 minutes before serving to set the layers for easier slicing.
