Lower-gi french onion soup FAQ:

How long should I simmer the soup for optimal flavor?

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.

What can I use as a substitute for pearl barley?

You can substitute pearl barley with quinoa or farro for a similar texture, but keep in mind that cooking times may vary accordingly.

How can I store leftovers of this soup?

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.

What adjustments should I make for a vegetarian version of this soup?

To make this soup vegetarian, replace the beef broth with vegetable broth and omit the cheese or use a plant-based cheese alternative.

How do I know when the onions are properly caramelized?

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.

Tips:

- 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.
