PREP TIME: 20 minutes
COOK TIME: 1 hours 20 minutes

Ingredients
2 pounds Yukon Gold potatoes, peeled
2 Peri & Sons white onions, cut into 1/4 inch thick slices
1/2 pound bacon, cut into 1/2 inch pieces
1/2 cup white wine
Fresh thyme sprigs
1/4 cup sour cream or crème fraîche
Salt and pepper, to taste
1 1/2 cups shredded Gruyère cheese
Brie cheese, sliced (remove some of the rind if desired)
1 tablespoon butter, for greasing casserole dish

Directions
Place the peeled potatoes in cold, salted water. Bring to a boil and cook until just fork-tender. Let cool slightly, then slice into thick rounds.

Preheat the oven to 375°F (190°C).

Next, in a skillet, fry the bacon pieces until just crisp. Remove and set aside on a paper towel lined plate.

In the same skillet, sauté the onions over medium heat until soft and lightly golden, about 15–20 minutes. Add fresh thyme and deglaze the pan with white wine, scraping up any browned bits.

Add the cooked bacon back into the onions, then mix in the sour cream and season with salt and pepper.

Grease a large casserole dish with butter and layer the potato slices on the bottom, then spread the onion-bacon mixture on top, followed by half of the shredded Gruyère. Repeat the layers, finishing with slices of Brie on top.

Bake in the preheated oven for 30–35 minutes, or until the cheese is melted and bubbling. Let rest for a few minutes, then serve.
