yellow onions, halved and sliced 1/2 inch thick
shredded Swiss cheese
grated Parmesan cheese
this is an absolute wonderful recipe. if you like onions this is the recipe to try, don't change anything.
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. ;)
This was pretty good. The onions were surprisingly sweet. Didn't have cream so used milk instead. I'm sure the cream would have made it richer but I don't know that it needed it. Will make again.
wonderful way to use onions. i used a variety of cheeses on the top because i didn't have enough swiss (cheddar, colby-jack) whole family enjoyed this as a side.
Wonderful side dish! My dinner guest loved them and asked for the recipe.
Rich and delicious is a great way to describe this recipe. I halved this recipe and we ate it all. Thanks Clammers for sharing.
So bad but sooooo good!
