Tender meatballs soaked in French onion soup, topped with melty Gruyère cheese, creating a comforting and flavorful dish perfect for any gathering.
For extra flavor, sauté finely diced onions before browning the meatballs. Use freshly grated cheese for best meltiness. Ground turkey or chicken can be substituted for a leaner option.
