Ingredients
- 2 cups leftover steak, thinly sliced
- 1 large onion, chopped
- 3 carrots, peeled and sliced
- 3 celery stalks, sliced
- 4 cloves garlic, minced
- 6 cups beef broth
- 1 can (14.5 oz) diced tomatoes
- 2 tbsp tomato paste
- 1 tsp dried thyme
- 1 tsp dried rosemary
- Salt and pepper, to taste
- 2 bay leaves
- 2 cups frozen peas
- 1/2 cup heavy cream (optional)
- Fresh parsley, chopped (for garnish)
Instructions
Preparation
Start by chopping the onion, carrots, and celery. Mince the garlic cloves. Slice the leftover steak into thin strips. This will help it cook evenly in the slow cooker.
Slow Cooking
Place the sliced steak, chopped vegetables, garlic, beef broth, diced tomatoes, tomato paste, thyme, rosemary, salt, pepper, and bay leaves in the slow cooker. Stir well to combine.

Cover the slow cooker and cook on low for 6-8 hours, or on high for 3-4 hours. This allows the flavors to develop and the meat to become tender.
Finishing Touches
About 30 minutes before serving, stir in the frozen peas. This will help them retain their color and texture. If you're using heavy cream, stir it in now as well.
Taste the soup and adjust the seasoning if necessary. Remove the bay leaves before serving.

Serving Suggestions
Ladle the soup into bowls and garnish with chopped fresh parsley. Serve with crusty bread or dinner rolls to soak up the delicious broth. This recipe should serve 6-8 people.
