Ingredients

• 4 thick-cut beef shanks (osso bucco style)
• 2 tablespoons olive oil
• 2 tablespoons butter
• 4 large onions, thinly sliced
• 5 garlic cloves, lightly smashed
• 2 tablespoons all-purpose flour
• 2 cups beef broth
• 1 cup dry red wine
• 1 tablespoon Worcestershire sauce
• 1 tablespoon brown sugar
• 2 teaspoons fresh thyme leaves
• 2 bay leaves
• Salt and freshly cracked black pepper, to taste
• Fresh thyme sprigs, for garnish

For Serving:

• Creamy mashed potatoes or crusty artisan bread

Instructions

1. Pat the beef shanks dry with paper towels and season generously on all sides with salt and freshly cracked black pepper.
2. Heat the olive oil in a large Dutch oven or heavy casserole over medium-high heat. Sear the beef shanks for 4–5 minutes per side until deeply browned. Transfer them to a plate.
3. Reduce the heat to medium and melt the butter in the same pot. Add the sliced onions and cook slowly for 20–25 minutes, stirring occasionally, until they become soft, sweet, and richly caramelized.
4. Stir in the smashed garlic and cook for about 1 minute until fragrant.
5. Sprinkle the flour over the onions and stir continuously to coat everything evenly, creating the base for a silky gravy.
6. Pour in the red wine, scraping the bottom of the pot to release the flavorful browned bits. Allow the wine to simmer for a few minutes.
7. Add the beef broth, Worcestershire sauce, brown sugar, thyme leaves, and bay leaves. Stir to combine.
8. Return the beef shanks to the pot, nestling them into the onion mixture.
9. Cover tightly and cook over low heat for 3 to 3½ hours, or until the beef is exceptionally tender and easily pulls away from the bone.
10. During the final 20 minutes of cooking, remove the lid to allow the gravy to reduce and thicken slightly.
11. Serve the beef shanks over mashed potatoes or with warm crusty bread, generously spooning the rich caramelized onion gravy over the top. Garnish with fresh thyme sprigs and an extra crack of black pepper.
