Preheat the oven to 300°F (150°C). Cut the beef into steaks about ½ inch (2 cm) thick and season them with salt. Thinly slice the onions and finely chop the herbs.
02 -
Heat a Dutch oven or oven-safe pot over high heat and add the oil. Sear the beef steaks in batches until both sides are dark brown. Avoid overcrowding the pot. Transfer the seared beef to a tray and cover with foil.
03 -
Add butter to the pot, reduce the heat, and cook the onions for at least 15 minutes, stirring occasionally, until they are deeply caramelized. Once done, remove the onions and set them aside.
04 -
Return the beef to the pot and sprinkle with the toasted flour. Mix to coat the meat evenly. Remove the beef again and layer the pot with alternating layers of meat, onions, and chopped herbs until all are used.
05 -
Pour the vinegar over the layered ingredients, followed by the brown sugar, thyme sprigs, bay leaf, salt, and pepper. Add the dark ale and any reserved juices from the seared beef. Add enough water to ensure the ingredients are just submerged.
06 -
Cover the pot with a lid and place it in the preheated oven. Cook for 3 hours, or until the beef is tender and easily falls apart.
07 -
Remove the thyme sprigs and bay leaf from the pot. Sprinkle the finished stew with freshly chopped herbs and a few capers for garnish.
