  1. Didn't realize I had grabbed beef broth instead of chicken broth until it was too late. Everyone in our house gave it three or four stars when made with beef broth. I will make it again sometime with the chicken broth and adjust our rating as needed.
  2. We love shrooms so I knew we would love this casserole, and we did! Next time I think I will add a Tbs or two of Dejon mustard for a little more flavor .I also omitted the salt.
  3. DH loved really enjoyed this! I used cheese crackers, did not add the 1/2 teaspoon of salt and used vege broth instead of chicken. Have a feeling I will be making this again soon! Thank you Rick B(2)
  4. VERY, VERY good! I love this recipe and will make it many times! It was perfect with Chia's Crispy Braised Duck Legs. I forsee it being a great dish for the holidays, and I'm going to email it to my family and friends! Took about 5 minutes to throw togeher too, so that's a bonus... I am on low carb diet, so subbed lc crumbs for the saltines and that was fine! I will try subbing parm. cheese next time. I added a splash of marsala wine to the egg mixture and that was nice, but I don't think the recipe needed it. Just my taste.
  5. Makes a very lovely side dish for roasted poultry, or anything else. I confess to having added 1/4 cup of dry white wine (cutting the broth to 1/2 cup), and I also added a bit of tarragon (about 1/2 teaspoon) to the mixture. I did cut the salt a bit (to 1/4 teaspoon) because of the salt on the crackers. It was wonderful with the roasted chicken. I also served it as a side with a roast pork, and it was equally good.


Cooking is a great passion of mine. I am a carpenter by trade. The recipes I submit are usually a mixture of ones that are brand new and ones that are 50 plus years old. I like to look through old cook books and find a new recipe I've never tried before.
