Ingredients
-
1 ½ cups full-fat cream
-
2 garlic cloves, minced
-
30g (2 tbsp) unsalted butter, melted
-
1.25kg (2.5 lb) starchy potatoes (Russet, Sebago, Maris Piper)
-
1 tsp salt
-
¼ tsp black pepper
-
2 ½ cups gruyere cheese (or substitute with colby, cheddar, havarti, or tasty cheese), freshly grated
-
2 tsp fresh thyme leaves (optional, but highly recommended)
Instructions
-
Preheat the oven to 375°F (190°C).
-
Peel the potatoes and slice them thinly (about ⅛-inch thick). Set aside in a bowl of water to prevent browning.
-
In a medium saucepan, heat the cream, minced garlic, and melted butter over medium heat. Stir until it starts to simmer, then remove from heat.
-
Drain the potatoes and layer half of them in a greased baking dish.
-
Pour half of the cream mixture over the potatoes and sprinkle with half of the salt, pepper, and grated cheese.
-
Layer the remaining potatoes on top, followed by the remaining cream mixture, seasoning, and cheese.
-
Cover the dish with aluminum foil and bake for 45 minutes.
-
Remove the foil and bake for an additional 15-20 minutes, or until the top is golden brown and the potatoes are tender when pierced with a fork.
-
Optional: Sprinkle with fresh thyme leaves just before serving for added flavor.
- Let the gratin rest for 5-10 minutes before serving.
Notes
-
For an extra crispy top, broil for the last 2-3 minutes of baking.
-
Russet potatoes are ideal for this dish because of their starch content, but any starchy potato variety will work well.
-
You can make this dish ahead of time and store it in the refrigerator for up to 2 days. Reheat in the oven before serving.
- Feel free to mix in some garlic or onion powder for additional flavor.
