- Heat the Pot: In a large pot or Dutch oven, heat olive oil over medium heat. Add the ground beef or sirloin strips and cook until browned, about 5-7 minutes. Drain excess fat if needed. 
- Add Onions and Garlic: Add diced onions and minced garlic to the pot. Sauté for 2-3 minutes until fragrant and translucent. 
- Add Mushrooms: Stir in the sliced mushrooms and cook for 5-6 minutes until softened and browned. 
- Deglaze the Pot: Pour in the Worcestershire sauce and stir to scrape up any browned bits from the bottom of the pot. This step adds depth to the flavor. 
- Add Broth and Seasonings: Pour in the beef broth and add paprika, salt, and pepper. Bring to a gentle simmer. 
- Add Noodles: Stir in the egg noodles and let them cook in the broth for 8-10 minutes until tender. 
- Incorporate Sour Cream: Reduce heat to low. Stir in the sour cream, ensuring it’s fully incorporated without curdling. Simmer for 2-3 minutes until the soup is creamy and well-blended. 
- Taste and Adjust: Taste the soup and adjust seasoning as needed, adding more salt, pepper, or Worcestershire sauce to balance the flavors. 
- Garnish and Serve: Ladle the soup into bowls, garnish with fresh parsley, and serve immediately. 
- Enjoy: Pair with crusty bread or a side salad for a complete meal.
