French Onion Scalloped Potatoes is a delicious and comforting side dish that combines the flavors of French onion soup with creamy scalloped potatoes. Thinly sliced potatoes are layered with caramelized onions, Gruyere cheese, and a rich beef broth. The dish is then baked until the potatoes are tender and the cheese is melted and golden. The result is a savory and cheesy potato dish with a hint of sweetness from the caramelized onions. It's the perfect accompaniment to any meal.
