  1. I'm basically not allowed in the door at holidays now unless I have this dish with me! It's the best...even people that don't care for onions love this!! VERY highly recommended!!
  2. Used FF half-n-half added a squirt of dijon and a little Frank's Hot Sauce. YUM. This would make an excellent starter for macaroni and cheese or thickened up a good dip.
  3. Way too buttery. Turned out to be onion butter soup.
  4. Made this last night and was pleasantly surprised! Tasted really good. I think I could've sliced more than 4 cups worth though. I'm glad I used a 1 1/2 qt instead of a 2 qt casserole dish. I should have probably used a 1 qt dish. Be sure to use the 2/3 cup Parmesan. It - Read more ...
  5. I made this as a side dish for Passover dinner and it was delicious. The only adjustment was I used fat free half and half instead of cream to cut down on calories.
  6. Absolutely yummy! I added a bit of fresh nutmeg to mine. This is basically a crustless onion quiche, and it is SO flavorful! Be sure to drain all of the butter/oil off of the cooked onions before adding them to the cream mixture. Sprinkle sweet paprika and dried parsley over the top for lovely color.
  7. Delicious and easy onion dish! I make it every year for Thanksgiving.
  8. A great side dish! A unanimous Easter dinner hit! No leftovers and the recipe went home with two happy families. I think next time I just might try decreasing the amount of butter by 1-2 tablespoons. (Howevewr, I can always go back to the original recipe if that is not satisfactory.)
  9. I can't get over how delicious this easy-to-prepare onion dish was. Make it per the instructions and double the recipe because it will all get eaten.
  10. This was very good. I did add some garlic in with the onions.
