Ingredients:
- 4.5 lbs bone-in beef short ribs, English cut
- 2 tsp kosher salt
- 1 tsp cracked black pepper
- 2 tbsp avocado oil
- 1 large yellow onion, diced
- 2 large carrots, peeled and sliced into rounds
- 2 stalks celery, diced
- 5 cloves garlic, smashed and peeled
- 2 tbsp tomato paste
- 1 cup dry red wine
- 2 cups low-sodium beef bone broth
- 2 tbsp balsamic vinegar
- 3 sprigs fresh thyme
- 2 sprigs fresh rosemary
- 2 dried bay leaves
Instructions:
- Pat the beef short ribs completely dry with paper towels to ensure a proper sear. Season all sides aggressively with kosher salt and cracked 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, browning each side for 2-3 minutes until a dark mahogany crust forms. Transfer seared ribs to the slow cooker.
- In the same skillet, add the diced onion, carrots, and celery. Sauté for 5-7 minutes until softened. Add the smashed garlic and tomato paste, cooking for another 2 minutes until the paste turns a deep rust color.
- Pour the red wine and balsamic vinegar into the skillet to deglaze, scraping up the browned bits (fond) from the bottom of the pan. Let the liquid simmer for 3 minutes to reduce slightly.
- Pour the vegetable and wine mixture over the ribs in the slow cooker. Add the beef bone broth, thyme, rosemary, and bay leaves.
- Cover and cook on Low for 8 hours (or High for 4 hours) until the meat is fork-tender and beginning to pull away from the bone.
- Remove the ribs and herbs. Skim excess fat from the surface of the sauce. For a silkier finish, strain the sauce through a fine-mesh strainer before serving over the ribs.
