In a large sauce pan over medium heat melt the butter

Add the diced onion and saute

Add the potatoes in one layer (spread the out all over the pan), let saute for a few minutes to a crisp brown and then turn over to crisp on the other side

Sprinkle with half the salt, pepper, rosemary, and thyme

Push the onions and potatoes to the side and add the beets in one layer in the middle of the pan

Saute the beets like you did the potatoes, turning only once and let crisp on both sides

Spread the chestnuts among the onions, potatoes, and beets

Let the chestnuts warm

Sprinkle the rest of the spices and herbs on top

Serve warm
