Ingredients:
- 4 large russet potatoes, peeled and thinly sliced
- 2 large yellow onions, thinly sliced
- 3 tablespoons butter
- 1 tablespoon olive oil
- 2 cloves garlic, minced
- 1 teaspoon sugar
- 1 cup beef broth
- 1 cup heavy cream
- 1 teaspoon fresh thyme leaves (or ½ teaspoon dried thyme)
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1½ cups shredded Gruyère cheese (or Swiss cheese)
- ½ cup grated Parmesan cheese
- Chopped parsley, for garnish (optional)
Instructions:
- Caramelize the onions:
Heat the butter and olive oil in a large skillet over medium heat. Add the sliced onions and stir to coat. Cook for 10 minutes, stirring occasionally, then add the sugar and garlic. Continue cooking for 15-20 minutes until the onions are golden brown and caramelized. Add the beef broth to deglaze the pan, scraping up any browned bits. Let it simmer for 2-3 minutes, then remove from heat. - Prepare the potatoes:
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish. Layer half of the potato slices evenly in the dish, slightly overlapping. - Assemble the bake:
Spread half of the caramelized onions over the potatoes. Sprinkle half of the thyme, salt, and pepper. Pour half of the heavy cream over the layer, followed by half of the Gruyère and Parmesan cheese. Repeat with the remaining potatoes, onions, seasonings, cream, and cheeses. - Bake:
Cover the dish with foil and bake for 40 minutes. Remove the foil and bake for an additional 20-25 minutes, or until the potatoes are tender and the top is golden and bubbly. - Serve:
Let the dish rest for 5-10 minutes before serving. Garnish with chopped parsley if desired.
This French Onion Potato Bake pairs wonderfully with roast chicken, steak, or even as a standalone vegetarian dish. Enjoy the comforting flavors of this rich, cheesy creation!
