Chicago has been experiencing bitter cold for the last couple of weeks. But that hasn’t stopped my husband and me from taking long walks. If you know how to dress properly, it can be rather invigorating and I’ll take it over the heavy snow that hit the East coast of the United States last week. The extreme cold, however, does make things very dry despite the use of humidifiers and lotions, so during this weather I allow my cooking to be a bit heavier on fats. This recipe (really more of a guideline than a hard and fast recipe) is pure comfort food. It’s fairly pliable, adapting well to personal tastes and ingredients on hand. Next time I might add some chopped chives and skip the prosciutto. Here is my version.
Lisa’s Au Gratin Potatoes
Yield: 6-8 servings
5-7 medium Yukon Gold potatoes
3-4 ounces prosciutto, cut into large dice and crisped in a frying pan (You can use bacon, if you prefer. This is what I had on hand and it’s also less fatty than bacon.)
8 ounces extra sharp cheddar, grated
1/4 cup grated Parmesan, Romano or Asiago cheese
About 3/4 teaspoon Kosher salt and fresh cracked black pepper to taste
1/2 teaspoon grated nutmeg
1.75 cups of skim milk (You can use whole if you prefer or part skim and part half & half)
2 large eggs
2-3 Tablespoons butter (I used garlic butter because I had Amish garlic butter that we received as a gift from Frances’ parents.)
2 Tablespoons Panko bread crumbs
- Preheat the oven to 375 degrees F. Generously butter an oval or rectangular pan with 2-inch sides. I like my heavy Le Creuset oval gratin pan, but a glass pan will work as well. The pan should be big enough to fit the all of the ingredients. If you are making this for a crowd, you will need a bigger pan.
- In a large pot, cover the potatoes with 2-3 inches of water. Bring it to a boil and simmer for 8 minutes. Remove the potatoes after 8 minutes and run under cold water to stop the cooking. When the potatoes are cool enough to handle, slice them about 1/4 inch thick. (I leave on the skins unless the skin starts to come off. In that case, just peel that extra skin away.)
- Line the buttered pan with the potato slices, over-lapping them slightly. After you have one layer of potatoes, take half of the crisped prosciutto and scatter it across the top of the potatoes. Do the same with half of the cheese mixture. Repeat this entire process with one more layer.
- Mix the eggs with the milk and add salt, pepper and nutmeg. Whisk to mix well. Pour the mixture over the potatoes. Sprinkle the top with the Panko bread crumbs and the paprika. Dot the top with more butter.
- Place the pan, uncovered in the oven and bake for about an hour. This can be made ahead and loosely covered. When you are ready to serve, uncover the pan and place it in a 350 degree F oven for about 10-15 minutes. Ovens vary but you want the top looking browned and crispy and the potatoes to be tender.
