Ham and Gruyere Potato Gratin

"Comes from Cooking Light -- July 2007 issue, however I've modified it slightly. Swiss can be substituted however it will not be quite as rich. To obtain uniformly thin potato slices use a food processor or a mandoline."

  1. I used yukon gold potatoes sliced extremely thin for this recipe, and they turned out just right. I wanted to use the gruyere cheese, but just couldn't spend that much. So I substituted Swiss. I used the minced onions, and I wish that I had added some garlic as well. The cheesey sauce kept the potatoes nice and moist. I used a little more ham than indicated, but I don't think it changed the taste of the dish very much. I made this for ZWT5.
  2. Scaled this back for 6 serves which served 4 with 1 serve left over (will be interesting to see how well it freezes). My biggest problem was that the sauce would not thicken so ended up adding another 2 tablespoon of flour (1 at a time - but added the hot milk to the flour, smoothed out and then added back to the main mix, did this again to get a mix that was thick like a custard mix . When tasting the dish that raw flour came through so sorry but would cook as per a basic whtie sauce though saute onions and then continue but follow my own ratio of 1 tablespoon of flour to 1 cup of milk but then I usually use about 11/2 to 1 tablespoon of butter for this mix, but as is was well like heated up milk even after boiling for about 6 minutes. For dietary reasons I did have to sub spring onions for the regular onions (which only took a minute to fry off) and well had to fry up some bacon for the ham as my ham disappeared (gone south down someones tummy I would say). Thank you Galley Wench, made for Wnt To The Market.
  3. After reading reviews, I made this with half low fat milk and half full cream. I know it is not low cal but it is what I had on hand. You can always use regular milk. Made it thicker and creamier. The Gruyere makes this dish! (Also 1 teaspoon Dijon Mustard really gives it a kick)
  4. Wasn't crazy about this but it wasn't bad, the sauce was just not as creamy I I would have liked. Perhaps because I used swiss instead of gruyere (which is 30.00 a lb. here!) . The flavor was good, but next time I will double the sauce. Thanks for posting!
