Ingredients:
- 4 lbs bone-in beef short ribs (English cut)
- 2 tbsp avocado oil
- 1 tsp kosher salt
- 0.5 tsp coarse black pepper
- 1 cup dry red wine (Cabernet Sauvignon or Merlot)
- 2 cups beef bone broth
- 2 tbsp tomato paste
- 1 tbsp balsamic vinegar
- 1 large yellow onion, diced
- 3 large carrots, cut into 1-inch chunks
- 2 stalks celery, sliced thin
- 6 cloves garlic, smashed
- 3 sprigs fresh thyme
- 2 sprigs fresh rosemary
- 2 dried bay leaves
Instructions:
- Pat the beef short ribs bone-dry with paper towels and season generously on all sides with kosher salt and coarse black pepper.
- Heat 2 tablespoons of high-smoke point oil in a large cast iron skillet over medium-high heat. Sear the ribs in batches until a deep brown crust forms on all sides (Maillard reaction).
- Transfer the seared ribs into a 6-quart slow cooker.
- In the same skillet, sauté the diced onion, carrots, and celery until softened. Stir in the smashed garlic and tomato paste, cooking for 2 minutes until the paste darkens.
- Deglaze the skillet with 1 cup of dry red wine, scraping up the browned bits (fond) from the bottom. Pour the mixture over the ribs in the slow cooker.
- Add the beef bone broth, balsamic vinegar, thyme, rosemary, and bay leaves to the slow cooker. Ensure the ribs are mostly submerged.
- Cover and cook on Low for 8 hours until the meat is fork-tender and begins to pull away from the bone.
- Carefully remove the ribs and vegetables. Strain the braising liquid through a fine-mesh strainer into a saucepan. Simmer on the stovetop for 10 minutes to reduce into a glossy mahogany glaze before serving.
