How to Make Caramelized Onion Red Lentil Soup
- Caramelize Onions: Heat olive oil over medium heat in a large pot. Add the sliced onions and salt, stirring occasionally for about 15-20 minutes until they turn golden brown and sweetly fragrant. If necessary, add a splash of water to prevent burning.

- Simmer: Reduce heat to low, cover the pot, and let it simmer for about 20 minutes. Stir occasionally until the lentils are tender and fully cooked, creating that lovely creamy base.
- Blend (optional): If desired, use an immersion blender to puree the soup for a smooth consistency, or leave it chunky for a rustic feel and texture.
