Pro Tips
1. Enhance Flavor with Sautéing Before adding the vegetables to the slow cooker, ensure they are well caramelized in the skillet. This enhances their flavor and adds depth to the soup.
2. Rinse Lentils Thoroughly Make sure to rinse the lentils multiple times under cold water until the water runs clear. This removes any dust or debris and helps with better cooking.
3. Customize the Consistency If you prefer a thicker soup, use an immersion blender to partially blend the soup after removing the bay leaf. Blend to your desired consistency, leaving some whole lentils for texture.
4. Boost Umami with Ingredients Consider adding a splash of soy sauce or a teaspoon of miso paste during the last phase of cooking to add a rich umami flavor.
5. Add Greens for Extra Nutrients Stir in some fresh spinach or kale during the last 30 minutes of cooking. The greens will wilt nicely and add extra nutrition and color to the soup.
