Simmer the soup for about 20 minutes after adding the broth and aromatics. Then, add the pearl barley and continue to simmer for an additional 30-40 minutes until the barley is tender.
You can substitute pearl barley with quinoa or farro for a similar texture, but keep in mind that cooking times may vary accordingly.
Store leftover soup in an airtight container in the refrigerator for up to 3 days. Reheat on the stove or in a microwave before serving.
To make this soup vegetarian, replace the beef broth with vegetable broth and omit the cheese or use a plant-based cheese alternative.
Onions are properly caramelized when they turn soft, golden brown, and develop a sweet flavor, typically achieved after about 25-30 minutes of cooking with added brown sugar.
- Slowly caramelize the onions over medium-low heat to bring out their natural sweetness and deepen the flavor of the soup.
- Make sure to stir the onions frequently to prevent them from burning and ensure even cooking.
- Use a high-quality beef broth to enhance the overall flavor profile of the soup.
- Toast the whole-wheat bread slices before adding them to the soup to help them hold their texture.
- For a more robust flavor, use aged Parmesan cheese for grating over the top.
- Feel free to substitute the mozzarella with Gruyere for a more traditional and richer taste.
- Add the pearl barley early in the cooking process to ensure it becomes tender and absorbs the flavors of the broth.
