Creating a delicious Korean Style Pot Roast is straightforward when you follow these steps:

1. Préheat Your Cookware: If using a slow cooker, set it to low. For an oven method, preheat your oven to 275°F (135°C).
2. Sear the Beef: Heat vegetable oil in a large skillet over medium-high heat. Season the chuck roast with salt and pepper, then sear on all sides until browned. This step adds flavor.
3. Prepare the Sauce: In a bowl, mix soy sauce, brown sugar, rice vinegar, sesame oil, minced garlic, and ginger. Stir until the sugar dissolves.
4. Layer the Vegetables: Place sliced onions, carrots, and potatoes in the bottom of the slow cooker or a Dutch oven. This will create a flavorful base.
5. Add the Beef: Position the seared beef on top of the vegetables.
6. Pour the Sauce: Drizzle the prepared sauce over the beef, ensuring it’s well-coated.
7. Cook the Roast: Cover and cook on low for 6–8 hours (slow cooker) or 4–5 hours (oven). The meat should become fork-tender.
8. Check for Doneness: Ensure the roast is cooked through and shreds easily when checked with a fork.
9. Let it Rest: Once done, remove the roast and let it rest for a few minutes; then shred or slice as desired.
10. Garnish: Serve with chopped green onions and a sprinkle of sesame seeds for added flavor and presentation.
