Creating Beef Vegetable Soup is straightforward when you follow these easy steps:

1. Brown the Beef: In a large pot, heat olive oil over medium heat. Add the beef cubes and sear until browned on all sides.
2. Sauté Aromatics: Add chopped onions and minced garlic to the pot. Cook for 2-3 minutes until onions become translucent.
3. Add Vegetables: Stir in the carrots, celery, potatoes, and zucchini. Mix well for about 5 minutes until slightly tender.
4. Incorporate Tomatoes: Add the can of diced tomatoes with their juices. Stir to combine.
5. Pour in Broth: Add the beef broth, bay leaves, and dried thyme. Increase the heat to bring the mixture to a gentle boil.
6. Simmer: Once boiling, reduce heat to low, cover, and let it simmer for 1-1.5 hours, or until beef is tender and flavors meld.
7. Add Green Beans: With about 10 minutes remaining, stir in the green beans. Allow to cook until they are tender but still bright green.
8. Season: Before serving, remove bay leaves and season with salt and pepper to taste.
9. Garnish: Serve the soup in bowls, garnished with fresh parsley for a pop of color.

Following these steps will ensure your Beef Vegetable Soup turns out delicious every time, providing a comforting meal for yourself and your loved ones.
