The History of Onion and Lemon Soup
While French Onion Soup is perhaps the most famous iteration, the concept of a savory onion broth has roots across many cultures, particularly in Europe. Simple onion soups were often sustenance for the poor, utilizing readily available ingredients. The addition of lemon, however, lends a distinctly Mediterranean influence, reminiscent of avgolemono-style soups found in Greek cuisine, which often feature lemon and egg. Our Hearty Onion and Lemon Soup takes inspiration from these traditions, combining the comforting depth of slow-cooked onions with the bright, clean finish of citrus, making it a modern classic that pays homage to ancient culinary wisdom.
This Hearty Onion and Lemon Soup offers a beautiful balance of flavors – sweet, savory, and zesty – that will undoubtedly become a staple in your recipe rotation.

Pro Tips

- Don’t rush the onion caramelization; it’s the foundation of the soup’s flavor.
- Always use fresh lemon juice and zest for the best vibrant flavor; bottled juice won’t provide the same brightness. If your soup seems bland, consider whether you’ve seasoned adequately or given the onions enough time to develop their sweetness.
