Ingredients

• 4 medium Russet potatoes
• 1 large Yellow onion
• 3 tablespoons Unsalted butter
• 2 tablespoons All-purpose flour
• 2 cups Whole milk
• 0.5 cups Heavy cream
• 1 teaspoon Garlic powder
• 1 teaspoon Salt
• 0.5 teaspoon Ground black pepper
• 2 tablespoons Fresh parsley
• 0.5 cups Shredded cheddar cheese

Directions

Step 1

Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish.

Step 2

Peel the potatoes and slice them into 1/4-inch thick rounds. Slice the onion into thin rings.

Step 3

Bring a large pot of salted water to a boil. Boil the potato slices for 5-7 minutes until they are barely tender. Drain and set aside.

Step 4

In a medium saucepan, melt the butter over medium heat. Stir in the flour and cook for 1-2 minutes to form a roux.

Step 5

Gradually whisk in the milk and heavy cream. Cook, stirring constantly, until the sauce thickens, about 3-5 minutes.

Step 6

Stir in garlic powder, salt, and black pepper. Remove the sauce from the heat.

Step 7

Layer half of the potatoes evenly in the prepared baking dish. Spread half of the sliced onions over the potatoes. Pour half of the cream sauce over the layer.

Step 8

Repeat the layers with the remaining potatoes, onions, and cream sauce.

Step 9

Sprinkle the shredded cheddar cheese evenly over the top of the dish.

Step 10

Cover the dish with foil and bake in the preheated oven for 25 minutes.

Step 11

Remove the foil and bake for an additional 15 minutes, or until the top is golden and bubbling.

Step 12

Garnish with fresh parsley before serving.
