Cheesy Scalloped Potatoes - cooking recipe

Ingredients

4 cups potatoes (thinly sliced, use a food processor or mandolin)
1/4 cup onion (chopped, for dietary purposes would use spring onion)
1 tablespoon flour
4 tablespoons butter (melted)
1 teaspoon salt (personally omit due to dietary reasons and use salted butter)
1/8 teaspoon pepper (personally would use more)
2 cups cheddar cheese (shredded)
1 1/2 cups milk (heated)

Preparation

Preheat oven to 350\u00b0F.
Grease 9 x 13 inch baking dish and spread half of your potatoes on the bottom of the dish, overlapping as necessary and then layer half of your onions.
In a small separate bowl, mix your flour, butter, salt and pepper then sprinkle half of this mixture to make the next layer and then on top of this layer half of your cheese and the repeat to create your second layer and now add milk and cook for 45 minutes or until the potatoes are good and tender (Just to warn you this is supposed to look pretty soupy. To be safe, you might want to put a piece of aluminum foil underneath your pan in case of run over,).
