Preheat the oven to 350º F. While the oven is heating, prep the ingredients.
Combine the olive oil, garlic rosemary and sage in a mixing bowl. Add the potatoes and toss until the potatoes are well coated with the herb/oil mixture.
Season with salt and pepper and toss again.
Transfer the potatoes to a shallow ovenproof container large enough so there's only a single layer. You can also use a shallow baking pan or even a sheet pan.
Roast the potatoes for about for about 45 minutes until they are just tender. A good way to check is to stick the tip of a knife into a potato. If there is little or no resistance, the potatoes are done. If there is, let them cook for a few minutes more.
When done, remove and serve immediately.
