Ingredients:
- 2 lbs (900g) beef chuck, cut into 1-inch cubes
- 2 tbsp olive oil
- 1 large onion, thinly sliced (about 1 ½ cups / 225g)
- 2 cloves garlic, minced
- 1 tbsp all-purpose flour (plus extra for dusting)
- 1 (12 oz/355ml) bottle stout beer (such as Guinness or similar)
- 2 cups (475ml) beef broth/stock
- 1 tbsp tomato paste
- 1 tsp dried thyme
- 1 bay leaf
- Salt and freshly ground black pepper to taste
- 2 large yellow onions, thinly sliced (about 3 cups / 450g)
- 2 tbsp butter
- 1 tbsp balsamic vinegar
- Pinch of brown sugar (optional, for extra sweetness)
Instructions:
- Toss beef with flour, salt, and pepper. Heat olive oil in Dutch oven. Sear beef in batches until browned on all sides. Remove beef and set aside.
- Add sliced onion to the Dutch oven and cook until softened. Add garlic and cook until fragrant.
- Pour in the stout beer and scrape up any browned bits from the bottom of the pot. Add beef broth, tomato paste, thyme, and bay leaf. Bring to a simmer.
- Return the seared beef to the Dutch oven. Cover and braise in a preheated oven at 325°F (160°C) for 2.5-3 hours, or until the beef is very tender.
- While the beef braises, melt butter in a large skillet over medium-low heat. Add onions and cook, stirring occasionally, until deeply golden brown and caramelized (about 45 minutes – 1 hour). Add balsamic vinegar and brown sugar (if using) during the last 10 minutes of cooking.
- Once the beef is tender, remove it from the oven. Discard the bay leaf. Stir in the caramelized onions. Season with salt and pepper to taste. Serve hot.
