Home Fries Using Cooked Potatoes

I like fried potatoes from scratch.
I also like these fried potatoes using
cooked potatoes. These are really good.

Ingredients:
2 large Russet potatoes, quartered
1 large onion,thinly sliced
1 tablespoon rendered bacon fat
Salt
Freshly ground black pepper

Directions:
Heat oil in a skillet
on medium high heat until sizzling.
Place a single layer of potato slices
on the bottom of the pan.
Add a light layer of sliced onions.
Sprinkle with salt and pepper.
Add another layer of potatoes,
another layer of onion slices,
sprinkle again with salt and pepper.
Keep layering until you've
used up your potatoes and onions.
Lower the heat to medium and cover the pan.
Let cook for about 10 minutes,
until the potato layer
at the bottom is nicely browned.
You can move aside a little bit with a fork
to see if the bottom edges are browned.
Flip the potatoes over,
a section of the pan at a time,
so that the layer that was on the top
is now on the bottom,
and the browned potatoes are now on the top.
Add more oil. The oil will help the browning.
Cover and let cook for another 5-10 minutes,
until the bottom layer is now browned.
Once the bottom layer is browned,
remove the lid of the pan and let
continue to cook for 5 more minutes.
This additional cooking will help
the potatoes dry out just a little bit more.
Season with salt and serve.
