Heat the oven to 375°F.

If some carrots are thicker than others, then halve them so they will cook evenly. Lay them in a single layer in a small roasting pan. Add the stock, wine, garlic, thyme, bay leaf, and peppercorns and sprinkle with salt to taste. Cover with foil and bake for 30 to 40 minutes, until the carrots are very tender. Transfer the carrots to a serving dish and keep warm.

With the back of a fork crush the garlic and thyme into the cooking liquid. Set the roasting pan over medium heat for a minute or two, stirring to concentrate the flavor; adjust the seasoning with salt and pepper and strain.

Spoon the liquid over the carrots, drizzle with oil and serve.
