Creating a delicious Japanese Beef Curry is easy if you follow these simple steps:

1. Prepare the Ingredients: Chop the onions, slice the carrots, dice the potatoes, and cut the beef into bite-sized pieces. Mince the garlic and ginger as well.

2. Brown the Beef: In a large pot, heat the vegetable oil over medium-high heat. Add the beef pieces and season with salt and pepper. Brown the beef on all sides, approximately 5-7 minutes. Remove the beef and set it aside.

3. Sauté the Aromatics: In the same pot, add the chopped onions. Sauté until they become translucent, about 5 minutes. Add the minced garlic and ginger, cooking for another 1-2 minutes until fragrant.

4. Add Vegetables: Return the browned beef to the pot. Add the sliced carrots and diced potatoes, stirring to combine.

5. Add Liquid and Simmer: Pour in the beef broth, soy sauce, and Worcestershire sauce. Bring the mixture to a boil, then reduce the heat to low. Cover and let it simmer for about 40-50 minutes, or until the beef is tender.

6. Incorporate Curry Powder: After the beef is tender, stir in the curry powder. Allow it to simmer for an additional 10 minutes, stirring occasionally until the sauce thickens.

7. Serve: Taste the curry and adjust the seasoning if necessary. Serve the Japanese Beef Curry hot over cooked rice and garnish with chopped green onions if desired.
