Description
This French Onion Potato Bake blends caramelized onions, roasted Yukon Gold potatoes, and melty Gruyère cheese into one bubbling, golden dish of comfort. It’s inspired by the classic soup, reimagined into a hearty side dish or main. Perfect for holidays or cozy dinners at home.
Ingredients
3 pounds Yukon Gold potatoes
2 tablespoons olive oil
1 teaspoon salt
½ teaspoon black pepper
3 large yellow onions thinly sliced
4 tablespoons unsalted butter
½ cup beef or vegetable broth
1 tablespoon fresh thyme or 1 teaspoon dried thyme
2 cups shredded Gruyère or Swiss cheese
Additional salt and pepper to taste
Fresh thyme or chives for garnish
Instructions
1. Preheat oven to 400°F (200°C). Chop potatoes into 1-inch chunks and toss with olive oil, salt, and pepper. Roast for 25–30 minutes on a baking sheet until golden and fork-tender.
2. While potatoes roast, melt butter in a skillet over medium heat. Add sliced onions and cook, stirring often, for 25–30 minutes until caramelized. Add broth, thyme, and a pinch of salt and pepper. Simmer for 5 more minutes until thickened.
3. Reduce oven to 375°F (190°C). Transfer roasted potatoes into a baking dish. Add caramelized onions and gently mix to coat evenly.
4. Sprinkle shredded cheese over the top. Bake uncovered for 15–20 minutes until cheese is melted and golden around the edges.
5. Remove from oven and garnish with fresh thyme or chopped chives. Let cool slightly before serving.
Notes
Let the onions caramelize slowly—don’t rush them or they won’t develop their deep flavor.
For best texture, shred the cheese fresh instead of using pre-shredded.
