Creating this Delicious Beef Stew and Dumplings can be straightforward by following these simple steps:

1. Brown the Beef: In a large pot, heat the vegetable oil over medium-high heat. Add the beef cubes in batches, searing until browned on all sides. Remove and set aside.
2. Sauté the Vegetables: In the same pot, add the onion, garlic, carrots, and celery. Cook for about 5 minutes until softened.
3. Add the Beef Back: Return the browned beef to the pot and stir to combine with the vegetables.
4. Pour in the Broth: Add the beef broth, potatoes, thyme, bay leaf, and Worcestershire sauce. Stir well.
5. Season: Season with salt and pepper to taste. Bring the mixture to a boil.
6. Simmer: Reduce the heat to low and cover the pot. Let it simmer for about 1.5 hours, stirring occasionally, until the beef is tender.
7. Make the Dumplings: While the stew simmers, mix the flour, baking powder, salt, and parsley in a bowl. In another bowl, whisk the milk and egg together. Combine the wet and dry ingredients until just mixed; do not overmix.
8. Add Dumplings: After the beef is tender, drop spoonfuls of the dumpling mixture onto the surface of the stew. Cover the pot and cook for another 15-20 minutes until the dumplings are fluffy and cooked through.
9. Serve: Remove the bay leaf and taste for seasoning, adjusting as needed. Serve the stew hot with dumplings on top.
