Scalloped or Au Gratin Potatoes

I’ve been tweaking this recipe for a little while. I have a version that has loads of calories from butter and cream, but wanted something simpler for “everyday” meals. This only takes about 15 minutes to put together and is so much better than the boxed stuff! 6 Red Potatoes 1 1/2 cups Milk (whole fat or almond milk) 1 cup Cheese (sharp cheddar or gruyere) 3 Tablespoons Butter 2 Tablespoons Flour 2 teaspoons Garlic Granules 1/4 teaspoon Black Pepper 1/8 teaspoon All Purpose Seasoning 1/8 teaspoon Parsley Heat oven to 350° F. Wash/scrub or peel the potatoes. Slice relatively thin ... I use a mandolin to get even slices about 1/8 inch thick. Grease the bottom of a 13x9 baking dish with 1 Tablespoon butter. Layer the potatoes in the baking dish. Using a whisk or stick blender, mix the remaining butter, milk, flour, and spices in a small bowl or large measuring cup. Pour the milk mixture over the potatoes and cover the baking dish with foil. Bake at 350° F for about an hour. Remove the foil and bake an additional 20 minutes. If adding the cheese, evenly sprinkle over the potatoes and bake at 350° F for an additional 10 minutes or until the cheese begins to brown.
