These Hasselback French Onion Soup Baked Potatoes are a delicious twist on the classic French onion soup. The potatoes are sliced and roasted until crispy on the outside and tender on the inside, then topped with caramelized onions, melted cheese, and a savory broth. The result is a comforting and flavorful dish that combines the best of both worlds - the richness of French onion soup and the heartiness of baked potatoes.
