Ingredients
Butter
1/4 cup (melted)
All-purpose flour
1/4 cup (sifted)
Half-and-half cream
2 cups (at room temperature)
Fresh rosemary
1 tablespoon (minced (or 1 teaspoon dried))
Garlic
1 clove (minced)
Salt
1 teaspoon
Black pepper
1/4 teaspoon
Potatoes
3 lbs (peeled and sliced thinly (1/8 inch))
Parmesan cheese
2/3 cup (grated)
Instructions
1
Preheat your oven to 350°F (175°C).
2
In a large saucepan, melt the butter over medium heat. Once melted, stir in the flour to create a smooth paste (roux).
3
Gradually whisk in the half-and-half cream, ensuring there are no lumps. Continue to cook, stirring constantly, until the mixture comes to a boil and thickens, about 2 minutes.
4
Remove the saucepan from the heat and mix in the minced rosemary, garlic, salt, and pepper, followed by the sliced potatoes. Stir until the potatoes are evenly coated with the cream mixture.
5
Lightly grease a 13x9x2 inch baking dish. Pour the potato mixture into the dish, spreading it out evenly.
6
Sprinkle the grated Parmesan cheese evenly over the top of the potatoes.
7
Cover the dish with aluminum foil and bake in the preheated oven for 45 minutes.
8
After 45 minutes, remove the foil and bake for an additional 10-15 minutes, or until the potatoes are tender and the cheese is golden and bubbly.
9
Allow to cool slightly before serving.
