Preheat oven to 180℃ (160℃ fan forced). Place flour, paprika, salt and pepper into a freezer bag, add the beef and shake well to coat. Heat 1 tablespoon of the oil in a large flameproof casserole pot or Dutch oven over medium-high heat. Brown the beef, in 2-3 batches for 5-6 minutes, turning to cook on all sides, until the beef is well browned. Add a little extra olive oil between each batch if required. Transfer to a plate. Reserve any leftover flour/paprika mixture left in the freezer bag and set aside.
Heat a further 1 tablespoon oil in the pan. Add the bacon and cook for 5 minutes.. Add the eschalots, garlic and anchovies, cook 2 minutes then add the leek, carrots and balsamic vinegar. Cook for a further 5 minutes scraping up the browned bits from the base of the pan.
Add the tomato paste and reserved flour/paprika mixture and stir for 1 minute. Return the beef to the pan, along with any juices, and add the red wine, beef stock, bay leaves, oregano or thyme and sugar. Stir to combine then bring gently to the boil. Cover with a lid and carefully transfer to the oven. Bake for 1 hour 30 minutes.
Remove the pot from the oven, add the potatoes then return for a further 1 hour or until the potatoes and beef are tender and the sauce has thickened slightly. Taste and adjust seasoning with salt and pepper. Discard bay leaves and herbs. Allow to stand for 10 minutes at least before serving. Sauce will thicken slightly on standing. Serve warm with fresh crusty bread and steamed green beans. Garnish with chopped fresh herbs and a good dash of cracked black pepper. Enjoy :)
