French Onion Grilled Cheese (From the Sandwich King)

READY IN: 1hr 40mins
Recipe by Dantana

This recipe has a twin! Be sure to pair it with 'Roasted Tomato Bisque' for a double whammy in the comfort food department. The carmalized onions are perfect with the sharpness of the tomato soup and soft goodness of the cheeses used. A perfect pair if there ever was one! When cooking the onion be sure to let them get nice and brown to maximize flavor!

We really enjoyed these! Didn't serve them with your soup, but another that I had made. I used American one one side of the onion and shredded mozzarella and some parmesan on the other. I don't think you could go wrong using any easy to melt cheese. The onions were not overpowering, just fabulous. Perfect balance of cheese and onion. Thanks for sharing this delicious recipe.
