2 cups of milk
1 1/2 tsp salt
1 clove of garlic - mashed (you can omit this if you don't want garlic in it, but it gives nice taste)
2tbsp AP flour
3 tbsp of finely chopped green onion
1/2 cup of heavy cream
Shredded mozzarella cheese for topping
Peel potato, wash them and slice them evenly measuring 5mm.
In a pan pour the milk, salt, nutmeg, mashed garlic, and flour - whisk them, and bring to boil until thickens.
Scrub a baking form with butter, and put at the bottom a line of potatoes. Organize them nicely so that the finishing product turns out nice! So a line of potato, sprinkle green onion, put half of the cream on it then put the milk mixture on it, and continue doing another layers until done.
Once all layers are done, bake at 220 C, covered with aluminum foil for around 20min (Pinch the potatoes with a tooth pick to see if its done), then take out the foil and sprinkle the cheese. Bake another 5 minutes.
Delicious, and simple!
