Season bone-in beef short ribs with salt and pepper to taste. Heat canola or vegetable oil in a large skillet over medium-high heat. Sear each side of the ribs until browned, rendering longer on the fatty sides. Work in batches to avoid overcrowding. Transfer ribs to a 5-6 quart slow cooker. Scrape any bits from the skillet into the slow cooker for added flavor.

Pour beef broth, Worcestershire sauce, garlic, onion powder, rosemary, and bay leaf into the slow cooker. Gently stir the mixture.

Add prepared carrots and onions to the slow cooker. Cover and cook on low for 6-8 hours, until the meat is tender and falls off the bone.
04 -
Remove cooked vegetables and ribs from the slow cooker. Cover them with foil to keep warm. Strain the remaining liquid into a medium saucepan. Heat over medium-high heat for 15-20 minutes, reducing the liquid by half. Taste and adjust seasoning with salt and pepper, if necessary.

Mix cornstarch and water to create a slurry. Slowly pour the slurry into the simmering sauce, whisking constantly for 2-3 minutes. Repeat the process with an additional slurry if a thicker consistency is desired.

Serve the short ribs and vegetables over mashed potatoes. Spoon gravy over the top and garnish with chopped parsley, if desired.
