Equipment
Method
- Preheat your oven to 375°F (190°C).
- Peel the russet potatoes and slice them into thin rounds, about 1/8 inch thick.
- Soak the sliced potatoes in a bowl of cold water to prevent them from browning.
- Butter a 9x13 inch (23x33 cm) baking dish generously.
- Drain the potatoes and layer half of the slices in the prepared dish.
- In a medium saucepan, combine heavy cream, minced garlic, salt, and black pepper over medium heat.
- Bring the mixture to a simmer, stirring gently to infuse the garlic flavor.
- Remove the saucepan from the heat and stir in the shredded cheddar and Gruyère cheeses until the sauce is smooth.
- Pour half of the cheese sauce over the first layer of potatoes.
- Layer the remaining potatoes on top and pour the rest of the cheese sauce over them.
- Cover the dish with aluminum foil and bake for 45 minutes.
- Remove the foil and continue baking for an additional 15 minutes, or until the top is golden brown and the potatoes are tender when pierced with a fork.
Notes
Slice russet potatoes to 1/8 inch for optimal cream absorption and a velvety finish. Layer potatoes with cheeses for a melting contrast; alternate Gruyère and cheddar for complexity.
