Ingredients
- 4 medium Russet potatoes
- 2 cups Heavy cream
- 1 cup Whole milk
- 2 tablespoons Dijon mustard
- 2 cups (shredded) Sharp cheddar cheese
- 2 cloves (minced) Garlic
- 1 tablespoon (for greasing) Unsalted butter
- 1 teaspoon Salt
- 0.5 teaspoon Ground black pepper
- 1 teaspoon (optional, chopped) Fresh thyme
Directions
Step 1
Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with unsalted butter, ensuring even coverage to prevent sticking.
Step 2
Peel the potatoes and slice them into thin, even rounds (about 1/8 inch thick) using a sharp knife or mandoline. Set the slices aside in a bowl of cold water to prevent browning.
Step 3
In a medium saucepan over medium heat, combine the heavy cream, whole milk, Dijon mustard, and minced garlic. Season with salt, pepper, and fresh thyme if using. Heat the mixture until it begins to simmer, stirring occasionally, then remove from heat.
Step 4
Drain and pat the potato slices dry with a kitchen towel. Layer one-third of the slices evenly in the prepared baking dish. Sprinkle about one-third of the shredded cheddar cheese evenly over the potatoes.
Step 5
Pour one-third of the cream mixture over the cheese and potatoes, spreading it evenly. Repeat this layering process two more times, finishing with a layer of cream and cheddar cheese on top.
Step 6
Cover the dish tightly with aluminum foil and bake in the preheated oven for 40 minutes. Remove the foil and bake for an additional 20 minutes, or until the top is golden brown and the potatoes are tender when pierced with a knife.
Step 7
Allow the gratin to cool for 5-10 minutes before serving to set the layers. Serve warm as a side dish or enjoy as a main course with a crisp green salad.
