Start by melting a tablespoon or two of butter with a tablespoon or two of olive oil over medium heat in an oven safe pan:
While that is melting, slice your potatoes (I used about 5 medium sized russets) and preheat the oven to 350F:
Melt the butter and olive oil until the butter is bubbly:
Take the pan off the heat and start to lay in your potatoes:
Sprinkle on some fresh ground black pepper:
Sprinkle in your favorite cheese, in this case I used shredded Colby jack and sharp cheddar:
Layer on more potatoes, black pepper and cheese and repeat until the pan is full :
Bake in oven until the potatoes are tender and the cheese is a golden brown.
Let it sit to cool a few minutes and serve.
