Ingredients

  • 500 ml (2 cups) Alfredo sauce
  • 300 g (2 cups) medium shrimp, peeled and deveined
  • 300 g (2 cups) small scallops
  • 1 French shallot, finely sliced
  • 2 garlic cloves, minced
  • 150 g (1 ½ cup) mushrooms, sliced
  • 2 sprigs fresh thyme
  • 3 to 4 Swiss chard leaves, coarsely chopped
  • 60 ml (1/4 cup) dry white wine
  • 30 ml (2 tbsp) fresh parsley, chopped
  • 30 ml (2 tbsp) olive oil
  • 80 g (3/4 cup) Gruyère cheese, grated
  • 5 medium potatoes (1 kg), peeled and cut
  • 180 ml (3/4 cup) Alfredo sauce
  • 1 egg yolk
  • Salt and pepper

Directions

  • Preheat the oven to 375 °F (190 °C).
  • Cook the potatoes in a large pot of salted boiling water until tender. Drain, mash with a potato masher, then stir in 3/4 cup Alfredo sauce. Adjust seasoning to taste. Transfer the mashed potatoes to a piping bag fitted with a star tip. Set aside.
  • Pat dry the scallops and shrimp with paper towels, then season. In a large skillet, sauté the seafood in a drizzle of olive oil until lightly cooked. Set aside on a plate.
  • In the same skillet, sauté the mushrooms with thyme in olive oil until nicely browned. Add the shallot and garlic, cook for a few seconds, then stir in the Swiss chard leaves. Deglaze with white wine and reduce until almost completely evaporated. Add the Alfredo sauce, let simmer for a few minutes to thicken, then gently fold in the shrimp, scallops, fresh parsley, and Gruyère cheese.
  • Spread a thin layer of mashed potatoes at the bottom of a gratin dish. Pour the seafood mixture on top. Using the piping bag, pipe a border of mashed potatoes around the dish. Brush the potato border with the egg yolk for a nice golden finish.
  • Bake for about 30 minutes, until the gratin is golden brown.
  • Serve hot, directly in the dish, as a shared main course.

Tips

  • You can also make individual portions by serving them in scallop shells.
  • The seafood mixture can also double as a sauce for pasta.
