Peel 3 medium sized potatoes, rinse under cold water and pat completely dry, cut each potato into thin slices that are ⅛ of an inch (½ cm) thick
Grease a large casserole dish with extra virgin olive oil, add the slices of potatoes into the casserole dish, I like to add them in single files and layered, but you can just add all the sliced potatoes at once and spread them around so they evenly cook
Thinly slice ½ of an onion, mix the onions around with your hands so they´re loose, evenly spread the onions over the potatoes
Grab a head of garlic and cut a slit on each clove (skin on) and place over the potatoes and onion
Drizzle everything with about 2 tablespoons (30 ml) of extra virgin olive oil, season with sea salt, black pepper, a generous 1 tsp of dried thyme and a generous 1 tsp of dried rosemary
Cover the casserole dish with foil paper and add into a preheated oven, bake + broil option (bottom + top heat), 190 C - 375 F
After 45 minutes remove the casserole dish from the oven, remove the foil paper and pour in a generous ¼ cup of white wine over the ingredients
Add the casserole dish back into the oven (uncovered) and raise the heat to 210 C - 425 F
After about 15 minutes the potatoes should be perfectly cooked, remove from the oven, sprinkle with freshly chopped parsley and serve at once, enjoy!
