Preparation

Step 1

Preheat oven to 375. Melt the butter in a nonstick frying pan. Add the chopped shallot under tender. I cooked mine for about 4 minutes. Add the flour, stirring constantly for 1 to 2 minutes. Slowly stir in the stock and heavy cream. Next, add the Gruyere cheese and thyme and stir until the cheese has melted. Season with salt and pepper. Add the potatoes and coat them well. Cover the pan and cook over medium heat for 15 minutes. Transfer the potatoes into an oven safe dish. Sprinkle the Parmesan-Reggiano cheese on top. Bake uncovered for 30-35 minutes until it is golden brown and bubbling. Let cool slightly before serving.
