Preheat oven to 425℉
Clean Potatoes. Cut in half (or quarters, if too large). Add to medium bowl.
In cast iron skillet, melt the Duck Fat over medium heat. Add the cut Potatoes. Stir to coat Potatoes, and cook over medium heat for about 10-15 minutes, stirring occasionally.
After about 10-15 minutes, once the potatoes have begun to cook through, add the pressed garlic, thyme leaves, salt, and pepper. Stir to disperse seasonings.
Remove from heat and transfer potatoes to a baking sheet sprayed with non stick cooking spray.
Turn each potato piece so that the cut side is facing up. Pop Potatoes into oven and cook for about 20-25 minutes, or until they are golden brown and have crispy edges.
