    1. Place onion, butter and brown sugar into a large frying pan over low heat. Cook, stirring occasionally, until the onions have caramelised, about 45 minutes.
    2. Preheat the oven to 180 C / Gas 4. Lightly grease a 20x30cm baking dish with butter.
    3. Place a single layer of potato slices in the bottom of the prepared baking dish. Cover with a thin layer of onions. Drizzle some of the cream, and sprinkle some of the rosemary over the layer. Repeat layers four times ending with onions, cream and rosemary.

    Made this yesterday! Best au gratin potatoes I have ever had! I didn't have double cream so I used condensed milk instead. Delicious!  -  22 Mar 2015


    This sounds absolutely gorgeous with the caramelised onions in - I'll have to try it!  -  10 May 2010


    I must admit I did change this recipe slightly. I did not add brown sugar, because carmelized onions are very sweet on their own, I didn't want it to be a dessert. I also peeled my potatoes, I just don't like the skin. I also did not add the rosemary, partly because I didn't have any and partly because I don't care for that either. But this is the only way I will make "escalloped" potatoes from now on. No dried up potatoes for me anymore. So creamy and flavorfull. My husband raved about these. A must for company or a pot luck if you want to show off! A+A+A+  -  21 Mar 2005  (Review from Allrecipes US | Canada)
