Preheat oven to 325°F (165°C).
Season chuck roast generously with salt and black pepper.
Heat oil in a large Dutch oven over medium-high heat. Sear roast on all sides until deeply browned. Remove and set aside.
Add onion to the pot and cook until softened. Stir in garlic and ginger and cook 30 seconds until fragrant.
Pour in beef broth, soy sauce, brown sugar, rice vinegar, and sesame oil. Scrape up browned bits.
Return roast to the pot and add carrots.
Cover and transfer to the oven. Braise for 3 hours, until beef is fork-tender.
Remove roast and let rest. Simmer sauce on the stovetop if thicker sauce is desired.
Slice or shred beef and serve with sauce spooned over the top. Garnish if desired.
