Creating this flavorful Steak au Poivre Soup is straightforward. Here’s how to do it:

1. Prepare the Steak: Season the diced steak with crushed black pepper and a pinch of salt.
2. Brown the Steak: Heat 2 tablespoons of olive oil in a large pot over medium-high heat. Add the steak and cook until browned on all sides, about 4-5 minutes. Remove the steak from the pot and set aside.
3. Sauté the Aromatics: In the same pot, add the remaining tablespoon of olive oil. Add the chopped onion and sauté until translucent, about 3-4 minutes. Stir in the minced garlic and cook for an additional minute.
4. Add Broth: Pour the beef broth into the pot, scraping up any brown bits from the bottom for added flavor. Bring the mixture to a boil.
5. Stir in Cream: Lower the heat to a simmer and add the heavy cream. Mix well until fully incorporated.
6. Flavor the Soup: Stir in the Dijon mustard and Worcestershire sauce, allowing the flavors to meld together for 5 minutes.
7. Return the Steak: Add the browned steak back into the soup. Simmer for another 5-10 minutes until everything is heated through.
8. Adjust Seasoning: Taste and adjust seasoning with additional salt and pepper if needed.
9. Serve: Ladle the soup into bowls and garnish with fresh parsley.

By following these steps, you'll be able to create a richly flavored, comforting Steak au Poivre Soup that will undoubtedly delight those who enjoy it.
