Making Hearty Beef Stew can be a rewarding experience. Follow these detailed steps to create your dish:

1. Heat the Oil: In a large pot or Dutch oven, heat the vegetable oil over medium heat.
2. Brown the Beef: Add the beef cubes to the pot in batches. Brown on all sides, taking care not to overcrowd. Remove and set aside.
3. Sauté Onions and Garlic: In the same pot, add the chopped onion and sauté until translucent, about 5 minutes. Add minced garlic and cook for an additional 1-2 minutes.
4. Add Tomato Paste: Stir in the tomato paste, coating the onions and garlic for added richness.
5. Deglaze the Pot: Pour in a bit of beef broth, scraping the bottom of the pot to lift any browned bits.
6. Combine Ingredients: Return the browned beef to the pot. Add the remaining beef broth, Worcestershire sauce, thyme, bay leaf, salt, and pepper.
7. Add Vegetables: Stir in the carrots, potatoes, and celery.
8. Bring to a Boil: Increase the heat and bring the stew to a boil.
9. Simmer: Reduce the heat to low, cover, and let it simmer for 2 to 3 hours, or until the beef is tender.
10. Adjust Seasoning: Near the end of cooking, taste and adjust seasoning if necessary. Remove the bay leaf before serving.
11. Garnish: Serve hot, garnished with freshly chopped parsley.
