Preheat oven to 400 degrees Fahrenheit.

Heat a large ovenproof skillet over medium heat. Add oil to hot skillet. Place potatoes in skillet and brown for four to five minutes.

Turn over potatoes and remove from heat.

Pour in chicken stock, and add garlic, salt, and pepper to skillet. Place skillet in oven (or transfer to a pan or oven-safe plate).

Bake for 30 minutes or until potatoes are soft. If sauce is drying out toward the end, add more stock.

Spoon sauce over potatoes and serve.
