Preheat the oven to 400°F (200°C).
Prepare the potatoes: Peel the Yukon Gold potatoes and cut them into thick rounds, about 1-inch thick.
Season the potatoes: In a large mixing bowl, toss the potato rounds with melted butter, olive oil, garlic powder, onion powder, thyme, rosemary, salt, and pepper until well coated.
Arrange on a baking sheet: Lay the potatoes in a single layer on a large baking sheet, making sure they are not overcrowded.
Bake the potatoes: Roast in the preheated oven for 20 minutes.
Add broth: Remove the baking sheet from the oven, flip the potatoes, and pour the chicken broth over them. This helps create a rich, flavorful base while making the potatoes tender inside.
Finish baking: Return the potatoes to the oven and bake for an additional 20–25 minutes, or until the potatoes are golden and crispy on the edges, and the broth is mostly absorbed.
Garnish and serve: Sprinkle with chopped parsley before serving.
