Ingredients

For the Potatoes

• 2 lbs (900 g) russet or Yukon gold potatoes, peeled and thinly sliced
• 1 small onion, finely chopped (optional)

For the Cheese Sauce

• 3 tbsp (45 g) unsalted butter
• 3 tbsp (25 g) all-purpose flour
• 2 cups (480 ml) whole milk or heavy cream
• 1 cup (100 g) shredded cheddar cheese
• 1/2 cup (50 g) shredded Parmesan cheese
• 1/2 tsp garlic powder
• 1/2 tsp salt
• 1/4 tsp black pepper

For Topping

• 1/2 cup (50 g) shredded cheddar cheese
• 2 tbsp (10 g) chopped fresh parsley (optional, for garnish)

Directions

Step 1: Preheat the Oven

1. Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or non-stick spray.

Step 2: Prepare the Potatoes

2. Arrange half of the sliced potatoes in an even layer in the baking dish. Sprinkle with half of the chopped onion (if using). Repeat with the remaining potatoes and onion.

Step 3: Make the Cheese Sauce

3. In a medium saucepan, melt the butter over medium heat. Stir in the flour and cook for 1-2 minutes, whisking constantly, to create a roux.
4. Gradually whisk in the milk, ensuring there are no lumps. Cook for 3-5 minutes, stirring frequently, until the sauce thickens.
5. Remove the saucepan from heat and stir in the cheddar cheese, Parmesan cheese, garlic powder, salt, and black pepper until smooth.

Step 4: Assemble the Dish

6. Pour the cheese sauce evenly over the potatoes, ensuring all the slices are coated.

Step 5: Add the Topping and Bake

7. Sprinkle the remaining cheddar cheese over the top. Cover the dish with aluminum foil and bake for 45 minutes.
8. Remove the foil and bake for an additional 15-20 minutes, or until the potatoes are tender and the top is golden and bubbly.

Step 6: Serve

9. Let the dish rest for 10 minutes before serving. Garnish with chopped parsley if desired.

Notes

• Cheese options: Feel free to use a combination of cheeses, such as Gruyère, mozzarella, or Monterey Jack, for added flavor.
• Make-ahead: Assemble the dish up to a day in advance and refrigerate. Add an extra 10-15 minutes to the bake time if starting cold.
• Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven for the best texture.
