Ingredients

• 6 medium russet potatoes
• 4 tablespoons butter
• 1 large yellow onion
• 2 cloves garlic
• 2 tablespoons all-purpose flour
• 2 cups whole milk
• 1 cup sour cream
• 2 cups shredded cheddar cheese
• 1 cup Parmesan cheese
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 0.5 teaspoon paprika
• 0.5 teaspoon dried thyme
• 1 cup panko breadcrumbs
• 2 tablespoons olive oil
• 2 tablespoons fresh parsley (optional)

Directions

Step 1

Preheat the oven to 375°F (190°C) and grease a 9x13-inch baking dish with butter or cooking spray.

Step 2

Peel the russet potatoes and thinly slice them into rounds about 1/8-inch thick. Set aside in a bowl of cold water to prevent browning.

Step 3

In a large skillet, melt the butter over medium heat. Finely dice the onion and sauté until softened, about 5 minutes. Mince the garlic and add it to the skillet, cooking for another 1 minute until fragrant.

Step 4

Sprinkle the all-purpose flour over the onion and garlic mixture, stirring constantly for 1-2 minutes to cook off the raw flour taste.

Step 5

Slowly whisk in the milk, ensuring there are no lumps, and bring the mixture to a simmer. Once thickened, stir in sour cream, 1.5 cups of shredded cheddar cheese, and Parmesan cheese until smooth and creamy.

Step 6

Season the cheese sauce with salt, black pepper, paprika, and thyme. Taste and adjust seasoning as needed.

Step 7

Drain and pat dry the potato slices. Layer half of them evenly in the prepared baking dish. Pour half of the cheese sauce over the potatoes, spreading evenly with a spatula. Repeat with the remaining potato slices and cheese sauce.

Step 8

In a small bowl, mix the panko breadcrumbs with olive oil. Sprinkle this mixture evenly over the top of the casserole, followed by the remaining 0.5 cups of shredded cheddar cheese.

Step 9

Cover the dish with aluminum foil and bake for 30 minutes. Remove the foil and bake an additional 20 minutes, or until the potatoes are fork-tender and the topping is golden brown.

Step 10

Let the casserole rest for 10 minutes before serving. Garnish with freshly chopped parsley, if desired.
