It was a good recipe but after reading the review I decided to alternate garlic and onion slices between the layers. The onion gave it a good flavor and kept a little more moisture in the potato. Topped with a little sour cream it was a hit.
I have made these a bunch of times and they always turn out great. We do like them with more seasoning though. I melt together butter, olive oil, minced garlic, fresh thyme, chives, salt & pepper then brush over the potatoes before baking...so good. I never have a problem with the time or temp, 40 mins at 425 seems to be right on, crispy edges & fluffy insides. I wonder if maybe some are using potatoes too big, slicing too shallow or slicing too wide? Could it be that some are baking at 220F not realizing the recipe says 220C (425F)?
Iwould make these again if I added more flavor....maybe some bacon and or cheese as someone else did. Pretty bland as the recipe calls. I had to double my cooking time so you make want to work that in as well.
