French Onion Soup

There’s just something magical about a good bowl of French onion soup. Funny enough, I’m the only one in my family who likes it but I like to think I’m also the only one who can truly appreciate its deliciousness!

This soup is made with the simplest ingredients. Just onions, butter, broth and herbs but the transformation that happens is nothing short of incredible. It’s cozy, comforting, and packed with rich, deep flavor.

The secret? Patience. Caramelizing the onions takes about 1 ½ to 2 hours, and you really don’t want to rush this part. If the onions brown too quickly, the soup can turn bitter, and that would be such a shame. Low and slow is the key to achieving that perfect deep amber sweetness. Trust me, it’s worth every minute!
