Description
A comforting yet festive baked gratin made with tender sliced potatoes, flaky salmon, and a rich, creamy cheese sauce, finished with herbs and a golden top.
Ingredients
Scale
- 2 pounds Yukon Gold potatoes, thinly sliced
- 1 pound fresh salmon fillet, skin removed and cut into chunks
- 2 cups heavy cream
- 1 cup whole milk
- 3 cloves garlic, finely minced
- 1 medium onion, thinly sliced
- 1 1/2 cups Gruyere cheese, grated
- 1/2 cup Parmesan cheese, finely grated
- 2 tablespoons unsalted butter
- 2 tablespoons fresh dill, chopped
- 1 1/2 teaspoons salt
- 1 teaspoon freshly ground black pepper
- 1/4 teaspoon ground nutmeg
Instructions
- Preheat the oven to 375°F and lightly butter a medium baking dish.
- In a mixing bowl, combine the heavy cream, whole milk, garlic, salt, black pepper, nutmeg, and half of the chopped dill, stirring until well blended.
- Arrange half of the sliced potatoes in the baking dish, overlapping slightly.
- Evenly scatter half of the sliced onion and half of the salmon pieces over the potatoes.
- Sprinkle a portion of the Gruyere and Parmesan cheeses over the layer, then pour some of the cream mixture on top.
- Repeat the layers with the remaining potatoes, onion, salmon, cheeses, and finish with the remaining cream mixture.
- Dot the top with butter, cover loosely with foil, and bake for 45 minutes.
- Remove the foil and continue baking for 15 minutes, or until the top is golden and the potatoes are tender.
- Allow the gratin to rest for 10 minutes before serving.
Notes
- Slice the potatoes evenly to ensure consistent cooking.
- Let the gratin rest before serving so it sets properly.
- Use fresh salmon for the best flavor and texture.
- For a more golden top, place under the broiler for 1 to 2 minutes at the end.
