Step 1: Sear the Short Ribs

In a large skillet over medium-high heat, heat the olive oil. Season the short ribs generously with salt and pepper, then sear them in batches until browned on all sides, about 3-4 minutes per side. This step enhances the flavor and creates a nice crust on the meat.

Step 2: Prepare the Vegetables

In the same skillet, add the chopped onion and sauté for about 5 minutes until softened. Add the minced garlic and cook for an additional 30 seconds until fragrant. Remove from heat.

Step 3: Combine the Ingredients

In the slow cooker, combine the beef broth, red wine, soy sauce, brown sugar, Worcestershire sauce, and dried thyme. Stir well to combine. Add the seared short ribs and the sautéed onion and garlic mixture, ensuring the ribs are submerged in the liquid.

Step 4: Cook the Short Ribs

Cover the slow cooker and set it to cook on low for 8 hours or high for 4 hours. The ribs should be fork-tender and easily pull away from the bone when done.

Step 5: Serve

Once cooked, remove the short ribs from the slow cooker and let them rest for a few minutes. Skim any excess fat from the surface of the sauce, then serve the ribs with the sauce spooned over the top. Garnish with fresh parsley for a pop of color.
