These potatoes make a fabulous and inexpensive side dish! Oh, and did I mention incredibly easy? I have been craving these potatoes ever since we arrived back to our home about two weeks ago. This and chocolate, although I always seem to crave chocolate, so….yeah.
Anyways, this will make a whole 9 x 13 pan full of delicious creamy potatoes that people will go crazy over. Maybe not everybody will go crazy, but I sure did. I just love my carbs. And just as a side note about the inexpensive part, I’m talking super inexpensive– potatoes, onions, flour, milk, butter: ingredients that seriously cost pennies! Love it when that happens. (and, yes I realize I live in Idaho which happens to be potato central where everyone practically gives potatoes away, but I promise they are cheap everywhere!) So, cook up some ham and make these for dinner because, oh baby, are they heaven.
Delicious Potatoes Au Gratin
- 7 tablespoons butter divided
- 6 tablespoons all purpose flour
- 2 cups skim milk plus maybe 1/2 cup to keep your sauce from oven thickening, like mine did
- 1/4 teaspoon ground black pepper
- 1/4 teaspoon ground nutmeg
- 1 teaspoon salt you may want more- I don't like a lot of salt
- 1 large onion sliced
- 4-6 Idaho potatoes
- Preheat oven to 350 degrees. On stovetop, preheat large skillet and large pot to medium heat. (Skillet is for cooking the onions, pot is for making the sauce) To skillet, add 3 tablespoons butter. To pot, add 4 tablespoons butter. Using melted butter from skillet, take a pastry brush and grease 9 x 13 glass dish generously. Place sliced onions into skillet and cook until soft and lightly browned (7-10 minutes). In pot, once butter is melted whisk in flour. Cook 2 minutes. Slowly whisk in milk to prevent lumps. Once milk is fully incorporated, add in seasonings. Continue mixing until sauce starts to thicken. Continue thickening until its the consistency of pancake batter. (That probably doesn't help because pancake batters can be any sort of viscosity....hmm) Ok, you want it to be slightly thick because the sauce continues to thicken from the potato starches in the oven. If it gets overly thick, add in that extra milk I mentioned earlier. Kapish?Now, for the potatoes. Peel those little suckers and then rinse them well! Slice into 1/8th of an inch slices or thinner if you can. The thinner you cut them the quicker they'll cook. Just make sure they are all generally the same thickness. Now comes the fun part. Take about half the prepared sauce out of the pot and set aside. Toss all the potatoes and onions into the pot with the remaining sauce and stir to coat. More milk can be added if needed. Pour potatoes into prepared baking dish and spread evenly. Top with remaining reserved sauce. Cover with foil and bake 1-1 1/2 hours. Its really ok to cook the life out of these potatoes. They just get better and better. Serve with something yummy like ham! Then prepare to die and go to heaven!
