Reviews forNever-Fail Scalloped Potatoes
"I haven't tried this recipe so I'm not going to rate it yet.However these are not scalloped potatoes, these are Au Gratin potatoes. There is a misconception that the two are the same but they are not. Scalloped potatoes does not contain cheese.While this may seem trivial, if you are making a side dish for someone who either doesn't like cheese or for whatever reason cannot have cheese, you're going to go through a lot of recipes searching for real scalloped potatoes if it is constantly improperly named.@ChristinaCheese separates and curdles when overcooked.When making the bechamel add WARM milk SLOWLY to the roux and whisk hard and quickly until completely smooth before adding more.Cold milk, too much milk, or not whisking fast enough can cause the sauce to separate, curdle, or become lumpy.When adding the cheese, make sure the cheese is grated and not cubed. Grated cheese melts quickly and evenly whereas cubed cheese does not increasing the chance of it becoming overcooked. Always remove sauce from the heat before adding the cheese and whisk until incorporated.Turning the oven down to a lower temperature doesn't help because the potatoes have to be in the oven longer increasing the likelihood of the sauce breaking, but chances are the issue you're having is in the preparation of the sauce, since this is a common issue not just with au gratin potatoes but also homemade macaroni and cheese.I hoped this helped you. Good luck."
"Excellent recipe - these potatoes ALWAYS a big hit & easily doubled for company!!"
"I made this with the ingredients I had in the fridge/pantry, which was almost everything needed, except I only had 2% milk (not fat-free). This caused the sauce to be super, super thick so I had to add more milk than called for to thin it out a bit. Also, I baked it in a 9-in cake pan because I couldn’t find my regular cooking dish and I was getting hungry!Additionally, I only had shredded mozzarella and regular russet potatoes. All in all, turned out great. Cooking time was perfect for russet potatoes. In hindsight, I wish I had added fresh minced garlic to the cheese sauce to liven it up a bit since I only had mozzarella cheese, but was still very yummy."
"I made these as written, with the exception of using regular cheddar cheese, and they were good, however i knew I could make them better. The next time i cut 2 medim onions and caramelized them, adding in about 8 garlic cloves....we love garlic. Making the roux, I added an additional TBSP of butter and flour, whisking these until the roux turned brownish in color and had a nutty smell. Then I added the milk, a cup at a time, whisking constantly. I don't know how much pepper I used, a lot. I also more than doubled the cheese, not fat free. I added the onion/garlic mix to the cheese sauce and proceeded with the directions. I cut my potatoes as thin as my mandolin will allow, and it took about 90 minutes to bake. I also grated 1/2 cup parmesan cheese and bread crumbs over the entire casserole the last 15 minutes of baking. Delicious! You can mix up your cheeses as you like, you don't have to stick with cheddar."
"Very tasty, but needs longer cooking time. I added diced ham and doubled the sauce. Even though I sliced the potatoes extremely thin, it still took longer than I thought to cook. Would have again."
"Every time I make this recipe my sauce (sob) curdles ! I tried turning down the heat of the oven, par cooking the potatoes before baking, microwaving the chopped onions, didn't make any difference at all, Is there someone that can tell me why it curdles please?"
"An excellent recipe definitely tasty and really hit the spot on a chilly Wisconsin winter day. Having read some of the earlier reviews I went ahead and went ahead and made small changes in the recipe. I Increased butter to 3 tablespoons and used 2cps of whole milk as l prefer my Scalloped taters a little thinner. I preheated everything in the pan according to the recipe saving 1 tablespoon of the butter which l sliced into pats and placed on top of the final layer of potatoes and sauce. Then I put a ham steak on top removing the fat along the edge. I cooked this in a slow cooker on low heat until the potatoes were cooked to perfection."
"Great flavor. I will double the sauce next time as some reviewers suggested."
"leave covered for 60 mins and uncovered for at least 15, others have said more sauce, I liked the lesser sauce but a tad more would be good. I used yellow gold. 2/3 cup of onions and added 2 cloves pressed garlic into the sauce.this was very good to eat as others have said. I opted to add some smoked cubed ham as well.Will do this again for sure."
"Thank you for a Great Recipe! I had already made a little extra sauce and the scalloped potatoes came out perfect."
