  1. I made these to serve alongside a carrots and brussel sprouts. Very comforting dish, thank you!
     
  2. Great change from scalloped potatoes. I used the parmesan option, and they had a nice crusty top layer. Great with a pork roast. Next time I will also do the "can use more" option on the tarragon. :) I cut the recipe in half and cooked in a smaller baking dish.
     
  3. Wow! An excellant dish, just excellant, one that I will serve to company. This potatoe dish was a delight. The potatoes were nice and tender. The sauce created by the onions, garlic, tarragon & sherry was incredible, rich and savoury. I used sea salt. I will be making this dish often. Thank you so much for sharing.
     
  4. I certainly don't like sherry as a drink and I don't often use tarragon, but these ingredients blended beautifully in this scrumptious potato dish which we all thoroughly enjoyed. I used homemade chicken broth, and really recommend using this rather than a commercial broth. Clear instructions, easy to make: a wonderfully flavoursome dish which I'll certainly make again. Thanks for sharing.
