Found this recipe as I was looking for something to do with the 50lbs of onions that my husband brought home. I was a bit skeptical at first, but it smelled terrific and the taste was amazing! Very simple recipe, but great flavor!! Took it to a potluck dinner and the pan was scraped clean! My family begged me to make it again the next day because some of them didn't get it at the potluck. The only change I made was to use crushed Cool Ranch Doritos instead of the crackers, so that the recipe would be gluten-free.


I got this recipe from my Aunt recently and it really is simple and delicious. I doubled the recipe and I can't even describe what a hit this was with mine AND my hubby's family! The butter (use a real stick of butter not margarine!!) sour cream and parmesan cheese turns into the yummiest sauce you could imagine for vidalia onions! All I added was minced garlic, freshly ground sea salt and freshly ground black pepper. Also, make sure to use a few extra crackers in the topping and mix the cracker crumbs with a little butter, Yum!


I have made this several times now. The only thing different I did, was I diced most of the onions up, put a layer of onion rings on top. If you don't have Ritz crackers, you can use regular saltines crushed with a little melted butter. You can't tell the difference when it is baked. Thanks for the recipe.
