How to Make It
Heat a large skillet. Add the oil and heat until wisps of smoke appear. Add the meat, season generously with salt and pepper and brown on all sides over moderately high heat, about 4 minutes total. Using a slotted spoon, transfer the meat to a plate.
Melt the butter in the skillet. Add the carrots, garlic, potato and onion and cook until lightly colored, about 3 minutes. Stir in the flour. Add the red wine and simmer, scraping up any browned bits from the bottom of the pan. Add the stock, thyme sprigs and bay leaf and bring to a boil. Cover and simmer over moderately low heat until the carrots and potato are fork tender, about 6 minutes.
Add the peas and the meat along with any accumulated juices, cover and simmer until the meat is heated through and medium rare, about 3 minutes. Discard the bay leaf and thyme sprigs. Season with salt and pepper, garnish with thyme leaves and serve.
