# What You'll Need:

→ Potatoes

01 - 3.3 lbs Yukon Gold or Russet potatoes, peeled and thinly sliced (1/8 inch)

→ Cheese Sauce

02 - 3 tbsp unsalted butter
03 - 1 small yellow onion, finely chopped
04 - 3 tbsp all-purpose flour
05 - 2 cups whole milk
06 - 1 cup heavy cream
07 - 1 tsp Dijon mustard
08 - 1/2 tsp salt
09 - 1/4 tsp black pepper
10 - 1/4 tsp ground nutmeg (optional)
11 - 2 cups shredded sharp cheddar cheese
12 - 1 cup shredded Gruyère cheese

→ Topping

13 - 1/2 cup shredded cheddar cheese
14 - 1/2 cup shredded Gruyère cheese
15 - 1 tbsp chopped fresh chives or parsley (optional)

# Step-by-Step Directions:

01 - Preheat the oven to 350°F. Grease a 9x13-inch baking dish with butter or nonstick spray.
02 - Melt butter in a medium saucepan over medium heat. Add the chopped onion and cook until soft and translucent, about 3 to 4 minutes.
03 - Stir in flour and cook for 1 minute while stirring constantly to create a roux.
04 - Gradually whisk in whole milk and heavy cream. Continue cooking and stirring until the sauce thickens, approximately 5 minutes.
05 - Remove from heat and stir in Dijon mustard, salt, black pepper, and nutmeg. Fold in shredded cheddar and Gruyère until melted and smooth.
06 - Arrange half of the sliced potatoes evenly in the prepared baking dish. Pour half of the cheese sauce over the potatoes. Repeat the layers with the remaining potatoes and cheese sauce.
07 - Sprinkle the remaining shredded cheddar and Gruyère cheeses evenly over the top.
08 - Cover the dish with foil and bake for 40 minutes.
09 - Remove foil and bake an additional 20 minutes until the top is golden and potatoes are tender when pierced.
10 - Let the dish rest for 10 to 15 minutes before serving. Garnish with fresh chives or parsley if desired.
