Ingredients

• 4 large Russet potatoes
• 4 tablespoons Butter
• 4 tablespoons All-purpose flour
• 2 cups Milk
• 1 cup Heavy cream
• 2 cups Shredded sharp cheddar cheese
• 0.5 cups Grated Parmesan cheese
• 1 teaspoon Garlic powder
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 0.5 teaspoon Paprika
• 2 tablespoons Fresh parsley (optional, for garnish)

Directions

Step 1

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

Step 2

Peel the russet potatoes, then slice them into thin, 1/8-inch rounds. Set aside in cold water to prevent browning while preparing the sauce.

Step 3

In a medium saucepan over medium heat, melt the butter. Once melted, whisk in the flour to create a roux. Cook for 1-2 minutes, stirring constantly, until the mixture is golden and bubbly, but avoid letting it brown.

Step 4

Gradually whisk in the milk and heavy cream, ensuring there are no lumps. Cook the mixture over medium heat, stirring frequently, until it thickens into a smooth, creamy sauce, about 5-7 minutes.

Step 5

Remove the saucepan from heat and stir in the shredded cheddar cheese and Parmesan cheese until fully melted and combined.

Step 6

Add the garlic powder, salt, black pepper, and paprika to the sauce, and stir well. Adjust seasonings to taste if necessary.

Step 7

Drain the sliced potatoes and pat them dry with a paper towel. Spread half of the potatoes evenly in the prepared baking dish.

Step 8

Pour half of the cheese sauce over the potato layer, spreading it out evenly. Add the remaining potato slices on top, followed by the rest of the cheese sauce.

Step 9

Cover the baking dish tightly with aluminum foil and bake in the preheated oven for 40 minutes.

Step 10

After 40 minutes, remove the foil and bake for an additional 20 minutes, or until the top is bubbly and golden brown.

Step 11

Remove the dish from the oven and let it rest for 5-10 minutes before serving. Garnish with fresh parsley if desired.
