For flavor I would say definitely a 5 star recipe! There was a little something with the texture of the sauce that was unappealing (I'll have to play around & see if that can be tweaked) & I wasn't sure when or where to use the green onions, so I sprinkled them on top as a garnish. We loved the unique flavors imparted by the caramelized onion & the bacon. YUM! DH does not eat or like scalloped potatoes, as he & DD can't eat cheese, so I made half with mozzarella & sharp cheddar for DS & I and half without cheese for DH & DD. Everyone really liked the flavor in their portions. I think the horseradish is a nice addition & I may even add a little extra next time. I'm so happy to have found a scalloped potatoe recipe that has enough flavor to stand alone for those in the house that can't have the cheese. :) Thank you! Thank you! Thank you for posting your creation, Tooltime. It's going to be a recipe I will make again & again. Made & enjoyed for Spring 2009 Pick A Chef.
