Generously season the beef short ribs with salt and freshly ground black pepper on all sides.

Heat olive oil in a large skillet over medium-high heat. When the oil begins to shimmer, sear short ribs on all sides for 3 to 4 minutes per side until evenly browned. Transfer browned ribs to a slow cooker.

In the same skillet, add sliced onion and cook for 3 to 4 minutes until softened, scraping up any browned bits from the pan. Stir in minced garlic and cook for 30 seconds until fragrant.

Add beef broth, red wine (if using), soy sauce, Worcestershire sauce, tomato paste, brown sugar, smoked paprika, dried thyme, and dried rosemary to the skillet. Stir well and simmer for 2 minutes.

Pour the sauce mixture over the short ribs in the slow cooker. Add bay leaves.
06 -
Cover and cook on low for 8 to 10 hours or on high for 4 to 6 hours until ribs are very tender and easily separate from the bone.
07 -
Carefully remove the ribs from the slow cooker and cover to keep warm. For a richer sauce, pour the cooking liquid into a saucepan, skim off excess fat, and simmer over medium heat until thickened as desired.

Arrange short ribs on plates and spoon sauce over the top. Serve hot alongside preferred side dishes.
