Ingredients
- 2 tablespoons butter (plus extra for greasing)
- ½ medium onion, minced
- 1 clove garlic, minced
- 1¼ teaspoons salt
- ½ teaspoon ground black pepper
- ¾ cup chicken stock
- 1¼ cups heavy cream
- 1½ to 1¾ pounds russet potatoes, peeled and thinly sliced (5–6 potatoes)
- 2 cups sharp cheddar cheese, shredded
- ¾ cup Fontina or Provolone cheese, shredded
- ¼ cup Parmesan cheese, grated
- 1 tablespoon fresh parsley, chopped (for garnish)
Instructions
- Preheat Oven:
Preheat oven to 425°F (220°C). Grease an 8×8-inch baking dish or ramekins with butter. - Prepare the Cream Sauce:
Melt 2 tablespoons butter in a large skillet over medium heat. Add minced onion and sauté until soft, about 5 minutes. Stir in garlic, salt, and pepper, cooking for 30 seconds until fragrant. - Simmer the Potatoes:
Pour in chicken stock and heavy cream, stirring to combine. Add the peeled, thinly sliced potatoes, ensuring they are submerged. Bring to a gentle simmer, then reduce heat to medium-low. Cover and cook for 15-20 minutes, stirring occasionally, until potatoes are nearly tender but still firm. - Assemble the Dish:
Transfer the potato mixture into the greased baking dish, spreading evenly. In a separate bowl, mix cheddar, Fontina or Provolone, and Parmesan cheeses. Sprinkle evenly over the potatoes. - Bake:
Bake in the preheated oven for 10-15 minutes, until the cheese topping is melted, bubbly, and golden brown. Watch closely to avoid over-browning. - Garnish and Serve:
Let the dish rest for a few minutes after baking to set the sauce. Garnish with fresh parsley and serve warm.
Notes
- Use a mandoline for evenly sliced potatoes.
- Substitute Fontina with Gruyère or mozzarella for a different flavor profile.
- Make ahead by preparing the dish, refrigerating, and baking just before serving.
