Ingredients

For the Bake

4 large potatoes, thinly sliced
2 large onions, thinly sliced
2 cups shredded cheese (Swiss or Gruyère)
1 cup heavy cream
2 tablespoons butter
Salt and pepper to taste
Fresh thyme for garnish

Make sure to use freshly sliced ingredients for the best flavor.

Steps

Prepare the Onions

In a large skillet, melt the butter over medium heat. Add the onions and sauté until caramelized, about 20 minutes, stirring occasionally.

Layer the Ingredients

In a greased baking dish, layer half of the sliced potatoes, followed by half of the caramelized onions, and top with half of the cheese. Repeat the layers.

Add Cream and Season

Pour the heavy cream over the layered potatoes and season with salt and pepper.

Bake

Cover with foil and bake in a preheated oven at 375°F (190°C) for 40 minutes. Remove the foil and bake for an additional 20 minutes until golden and bubbly.

Let it cool for a few minutes before serving.

Expert Tips for Success

For perfectly caramelized onions, patience is key. Allow them to cook on low to medium heat, stirring occasionally to prevent burning. This slow cooking process enhances their natural sweetness and results in a deep, rich flavor that is essential for this dish.

When layering the potatoes, try to overlap them slightly to ensure even cooking and a cohesive texture. Using a mandoline slicer can help you achieve uniformly thin slices, which allows for even baking and a delightful mouthfeel.

Storage and Reheating

If you have leftovers, store the French Onion Potato Bake in an airtight container in the refrigerator for up to three days. To reheat, place a portion in a baking dish and cover it with foil to retain moisture. Heat in a preheated oven at 350°F (175°C) until warmed through, usually around 20-30 minutes.

This dish also freezes well. If you wish to freeze it, consider undercooking it slightly before freezing, as this will help maintain the texture when reheated. Wrap tightly in plastic wrap and foil to prevent freezer burn for up to two months.

Serving Suggestions

For a complete meal, serve your French Onion Potato Bake alongside a crisp green salad drizzled with a light vinaigrette. The acidity from the dressing will contrast nicely with the rich flavors of the bake, making each bite even more enjoyable.

Alternatively, pair it with protein options such as grilled chicken or roasted pork. The creamy, cheesy layers will elevate any dish and turn an ordinary dinner into a memorable feast.
