Directions

In a medium bowl, stir together the beef broth and flour until smooth. Mix in the cream and season with salt and pepper; pour over the onions. Sprinkle Swiss cheese and Parmesan cheese over the top.
  3. Bake for 25 to 30 minutes in the preheated oven, until cheese is golden brown and the sauce is bubbly.

I really wanted this recipe to be great - but it was a disaster! I should have known something would go wrong since onions give off a lot of water/juices when they cook! The end result was NOT a traditional "au gratin" dish but more of cheesy soupy onion mess. It was hardly edible and a great disappointment (not to mention waste of perfectly good onions)! My only recommendation/suggestion for fixing this would be to bake the onions first without the mixture - pour off the excess liquid - then add the flour/cream mixture and cheeses and bake again... that's the only thing that comes to mind to avoid the soup I ended up with. However, with that said - I will NOT be making this again!

This is absolutely one of my most favorite sides. I suggest, if you can find them in your area, using the sweets. And using Campbell's double strength beef broth really amps up the flavor, you'll just have to cut out the excess salt. And a little more cheese never hurt anyone. ;)
