Gather your ingredients so that you have everything close at hand on the counter or table. Grease a large casserole dish.
Prepare the Ingredients
Wash potatoes and remove any eyes on the potato. Using a sharp knife and cutting board, thinly slice the potatoes. (I always leave the peels on the potatoes.)Mince the onion. Slice or dice the processed cheese into small pieces.
Making the Layers
When you begin the layering process, start with the potatoes, then sprinkle with minced onion, all-purpose flour, and dried parsley. Dot bits of butter over the potatoes and finish with the processed cheese. Repeat the layers twice more.
Pour whole milk over all. Then sprinkle with kosher salt and freshly ground black pepper to taste.
Cover and cook in microwave for 15-20 minutes, (more or less, depending on the condition of your microwave) stirring mixture every 5 minutes until potatoes are tender and nicely browned.
This recipe will serve 4-6 people.
