I brought this dish to a holiday pot luck and got some good comments from happy onion eaters who went back for seconds. I followed the recipe, making three times the quantity for my crowd. Instead of the small pearl onions (too time consuming to handle 72 or more!) I cut some huge sweet onions into eight wedges, cooking them in boiling water as directed and then folding them into the cream sauce. I used bread in small cubes to cover the top of the casserole, which gave the finished dish a nice crunch in contrast to the creamy onions. I noticed a lot of people sprinkling salt and pepper on their portion, and think that next time I will increase the seasoning, including the cayenne pepper. All in all a successful and delicious recipe!

Very good. The only grocery store nearby was completely out of frozen onions AND those little boilers. *sigh* So I recruited my 11 year old to pop the pearl onions out after I blanched them. :D She pretty much took over this dish once she realized it was easy. LOL. We didn't add any salt because of my hunnie's diet, but did add about 1/8 tsp of ground mustard. We're definitely making this again!
