Ingredients

• 4 medium Russet potatoes
• 2 large Chicken breasts
• 4 tablespoons Unsalted butter
• 2 minced Garlic cloves
• 3 tablespoons All-purpose flour
• 2 cups Whole milk
• 1 cup Heavy cream
• 2 cups (shredded) Cheddar cheese
• 1 cup (grated) Parmesan cheese
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 0.5 teaspoon Paprika
• 1 tablespoon Olive oil
• 2 tablespoons (chopped) Fresh parsley

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with butter or non-stick spray.

Step 2

Peel and thinly slice the russet potatoes (about 1/8-inch thick). Set them aside submerged in cold water to prevent browning.

Step 3

Season the chicken breasts with a pinch of salt, black pepper, and paprika. Heat olive oil in a skillet over medium heat and sear the chicken until golden brown on both sides (about 3-4 minutes per side). The chicken doesn’t need to be fully cooked. Remove and let rest, then slice into thin strips.

Step 4

In a medium saucepan, melt the unsalted butter over medium heat. Add the minced garlic and sauté for about 30 seconds, until fragrant.

Step 5

Whisk in the all-purpose flour and cook for 1-2 minutes to create a roux. Gradually whisk in the milk and heavy cream, stirring constantly to avoid lumps. Cook until the sauce begins to thicken (3-5 minutes).

Step 6

Stir in the cheddar cheese, parmesan cheese, salt, and black pepper. Mix until the cheese has melted into a smooth sauce, then remove from heat.

Step 7

Drain the potato slices and pat them dry. Arrange 1/3 of the potato slices in an even layer at the bottom of the prepared baking dish. Top with half of the seared chicken slices and pour 1/3 of the cheese sauce over the top.

Step 8

Repeat the layers, finishing with a layer of potatoes and the remaining cheese sauce. Sprinkle additional shredded cheese on top, if desired.

Step 9

Cover the dish tightly with aluminum foil and bake for 40 minutes. Then, remove the foil and bake uncovered for an additional 20 minutes, or until the top is golden brown and bubbly.

Step 10

Let the Chicken Potato Au Gratin cool for 10 minutes before serving. Garnish with fresh parsley and serve warm.
