These potatoes are not for those watching their waistline..lol..but so tasty and rich. mmmmmm ..I have to make a double batch, for leftovers. We don't have these often,just as a treat now and then.I had to actually measure everything to put the recipe together. I don't usually measure when making these, so I hope I do okay on that part.
1This recipe is a double batch, would be for 4-5 people with left overs for the next day. If you want to cut the recipe in half. Cut the amount of potatoes in half, and the amount of milk and cream, flour and fat for roux..I always cook big for leftovers. The amount I made was for 4 people and leftovers for 4 the next day. That should give you a general Idea how to decide whether to half it or not. We love leftover scalloped potatoes..so good the next day..to give you a general idea, I used a 12x 16 x 4in deep lasagna pan, you want to use a pan to be able to spread the potatoes well ,not too many layers, so they cook evenly. You don't want a burnt top and not cooked potatoes.
21. I use my food processor to slice the potatoes about 1/4 inch thick. I was lazy today and didn't peel my potatoes. I like the rustic look. Wash the potatoes and slice, put in a bowl of cold water. Now, go ahead and slice the onion, same thickness. Set aside.
3In a large sauce pan, heat the fat, bacon grease, butter or oil on med-high roughly 4-5 min, add the flour, and whisk briskly till smooth . Keep whisking as you add the milk and cream, continue stirring making sure the sauce s smooth. Bring to a slow boil make sure you continue stirring, it should be getting thick now. When is to desired thickness, add nutmeg, stir, and set aside.
4Preheat the oven to 375
Spray the pan or casserole dish with cooking spray, makes cleaning so much easier.
Start spreading about half the potatoes evenly in the pan, then spread half the onions, salt and pepper the layer, add half the parsley,4 pats of butter and about 1/2 cup cheddar or more if you like, then spread about half the white sauce, repeat layering, starting with the potatoes. I also sprinkle about a tablespoon of flour on each layer, remember to season again.
Depending on the size of pan, or whether you are cutting recipe in half, I only used two layers; ending with the rest of white sauce.
If there is not enough sauce to your liking, add some milk to not quite cover the potatoes, but should be able to see that the potatoes have plenty of liquid, I usually add a splash more of milk..just for good measure.
5In a small bowl mix the other 1 cup of cheddar and panko bread crumbs, along with the garlic powder...spread the crumbs evenly atop the potatoes.
Now, as I said in the ingredients, I used russets today, sliced about 1/4 in thickness; baked at 375 for an hour with foil, then another hour without foil so the potatoes could get a nice golden brown crust....depending on what type of potato you use, the cooking time could change.
You should be able to tell the tenderness by poking with a fork. Enjoy! We sure did!! These are so flavorful and creamy..I have also added ham, bacon, if using as main meal, tonight they were used as a side.
