Making Korean Beef Stew is a straightforward process if you follow these steps:

1. Prepare the Beef: In a large pot, heat 1 tablespoon of sesame oil over medium-high heat. Add the beef short ribs and sear them until browned on all sides. Remove from the pot and set aside.

2. Sauté Aromatics: In the same pot, add the chopped onion, garlic, and ginger. Sauté until the onion becomes translucent.

3. Combine Ingredients: Return the beef to the pot. Add the beef broth, soy sauce, brown sugar, and black pepper. Stir well to combine.

4. Bring to a Boil: Increase the heat and bring the mixture to a boil. Once boiling, reduce the heat to low and cover the pot.

5. Simmer: Allow the stew to simmer for about 1.5 hours, stirring occasionally. This will help tenderize the beef and develop the flavors.

6. Add Vegetables: After 1.5 hours, add the carrots, celery, and mushrooms to the pot. Stir to combine and continue to simmer for another 30 minutes.

7. Taste and Adjust: Check for seasoning and adjust with additional soy sauce or sugar if necessary.

8. Garnish: Once the beef and vegetables are tender, remove the pot from the heat. Garnish with chopped green onions and sesame seeds.

9. Serve: Ladle the stew into bowls and enjoy!

By following these steps, you’ll create a Korean Beef Stew that is both flavorful and fulfilling, perfect for any occasion.
