Ingredients for French Onion Potato Bake

Here is a comprehensive list of ingredients you’ll need to create this delightful dish. The measurements below ensure a perfect balance of flavors:

Step-by-Step Directions

1. Preheat the Oven

Set your oven to 375°F (190°C) to ensure it’s ready when you assemble the dish.

2. Caramelize the Onions

In a large skillet, melt butter and olive oil over medium heat. Add the thinly sliced onions and cook, stirring occasionally, until they are deeply golden and caramelized. This process typically takes 20 minutes but is essential for achieving the signature French onion flavor.

Pro Tip: Adding a pinch of sugar can enhance the caramelization process if needed.

3. Prepare the Potatoes

While the onions cook, thinly slice your potatoes. Use a mandoline slicer for even slices, which ensures consistent cooking. Set the potatoes aside.

4. Create the Onion Broth Mixture

Once the onions are caramelized, add beef broth to the skillet. Stir well and bring it to a simmer. Allow the mixture to cook for an additional 5 minutes, then remove from heat.

5. Assemble the Casserole

Grease a 9×13-inch baking dish with butter or oil to prevent sticking. Begin layering:

1. Arrange half of the sliced potatoes in the dish.
2. Sprinkle with half of the salt, pepper, and thyme.
3. Pour half of the onion and broth mixture over the potatoes.
4. Sprinkle half of the Gruyère cheese evenly across the top.

Repeat these steps with the remaining potatoes, seasonings, onion mixture, and cheese.

6. Add the Cream

Drizzle heavy cream evenly over the entire dish. This adds a creamy, luxurious texture to the bake.

7. Bake the Dish

Cover the baking dish with aluminum foil and bake in the preheated oven for 45 minutes. This allows the potatoes to cook through while absorbing all the rich flavors.

8. Achieve the Golden Top

Remove the foil and bake for an additional 15 minutes or until the top is golden brown and bubbling. The cheese should form a delicious crust.

9. Cool and Serve

Let the dish cool for 5–10 minutes before serving. This helps the layers set and makes it easier to serve.
