  1. I loved the flavor of this dish. I thought that the combination was wonderful. The squash gave the dish a slightly sweet taste, as did the carmelied onions. I divided it into 2 dishes. Served one tonight and will take the other one to my mother's for Christmas. Thanks for sharing this recipe. I'll be making it again.
  2. Very nice dish. I halved the recipe, since there were only 3 of us. I also couldn't find fresh sage, so subbed the equivalent of dried. The topping baked in 10 minutes. :)
  3. This is a lovely recipe. I made it for Easter dinner and it was a hit. My only change would be to half the breadcrumbs. I also didn't use sage because I didn't have any, but will try it next time. The breadcrumbs kind of over powered the gruyere cheese in my opinion. I will make this again using a little less breadcrumbs. Thanks, Carole in Orlando
  4. This recipe was excellent! I couldn't find butternut squash, so used acorn squash instead. I also blanched the squash and potatoes to cut down on the cooking time. It only took about 10 minutes for the cheese and breadcrumbs to cook to golder brown instead on 30 minutes.

I love to cook - it's a major stress reliever for me and I thoroughly enjoy the reaction of others when they like my dishes! My other passion is sailing - BF and I plan to take off from Oregon toward the South Pacific in a couple years to live on his boat.
