Ingredients:
- 4 lbs bone-in beef short ribs
- 2 tsp kosher salt
- 1 tsp cracked black pepper
- 2 tbsp avocado oil
- 1 large yellow onion, diced
- 2 large carrots, sliced into rounds
- 2 stalks celery, diced
- 4 cloves garlic, smashed
- 2 tbsp tomato paste
- 2 cups dry red wine
- 2 cups beef bone broth
- 1 tbsp Worcestershire sauce
- 3 sprigs fresh thyme
- 2 sprigs fresh rosemary
- 2 dried bay leaves
Instructions:
- Pat the short ribs bone-dry with paper towels and season aggressively with salt and pepper. Heat avocado oil in a large cast iron skillet over medium-high heat until shimmering.
- Sear the ribs in batches for 3-4 minutes per side until a deep, mahogany crust forms. Transfer the seared ribs to the slow cooker.
- In the same skillet, sauté the diced onion, carrots, and celery in the rendered beef fat. Stir in the tomato paste and cook for 2 minutes until it reaches a brick-red color.
- Deglaze the skillet by pouring in the red wine, scraping the bottom with a wooden spoon to incorporate the fond. Transfer the liquid and vegetables into the slow cooker.
- Add the beef bone broth, Worcestershire sauce, 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 beginning to pull away from the bone.
