Slow-cooker red lentil soup

Slow-cooker red lentil soup is a hearty, nutritious, and convenient recipe perfect for meal prepping or cozy dinners. This soup is rich in vitamins, fiber, and plant-based protein, making it a wholesome choice for any diet. The slow cooker method allows the flavors to meld together beautifully, creating a comforting dish that requires minimal hands-on time.

Instructions:

1. Prepare the Vegetables:
- Dice the onion, carrots, and celery, ensuring they are all roughly the same size to ensure even cooking.
- Mince the garlic cloves and grate the fresh ginger root.
2. Sauté the Aromatics:
- In a skillet over medium heat, add the olive oil.
- Once the oil is hot, add the diced onion, carrots, and celery. Sauté for about 5-6 minutes, or until the vegetables are softened.
- Add the minced garlic and grated ginger to the skillet, and sauté for an additional 1-2 minutes, until fragrant.
3. Assemble the Soup in the Slow Cooker:
- Transfer the sautéed vegetables to your slow cooker.
- Add the ground cumin, dried coriander, canned red lentils, and vegetable broth to the slow cooker.
4. Cook the Soup:
- Set your slow cooker to the low setting and cook for 6-8 hours. Alternatively, you can cook on the high setting for 3-4 hours.
- Throughout the cooking process, the lentils and vegetables will become tender and the flavors will meld together.
5. Finishing Touches:
- Once the soup is cooked, taste and adjust seasoning as necessary. You may want to add salt and pepper to taste.
- If you prefer a smoother consistency, you can use an immersion blender to purée the soup to your desired texture.
6. Serve:
- Ladle the soup into bowls and serve hot.
- Optionally, garnish with fresh cilantro, a dollop of yogurt, or a squeeze of lemon juice for added brightness.

Tips:

- For extra depth of flavor, sauté the onions, carrots, and celery in olive oil before adding them to the slow cooker.

- Using fresh ginger root instead of ground ginger can enhance the flavor complexity of the soup.

- Feel free to adjust the spices to your taste – add more cumin or coriander if you prefer a stronger flavor.

- If the soup is too thick for your liking, you can add more vegetable broth or water to reach your desired consistency.

- Garnish with fresh herbs like cilantro or parsley for an added burst of freshness.

- Add a squeeze of lemon juice before serving to brighten the flavors.

- For a creamier texture, you can blend a portion of the soup with an immersion blender.

Once cooked, the slow-cooker red lentil soup will greet you with inviting aromas and a rich, savory flavor profile. Ladle into bowls, and enjoy it as is, or with a side of crusty bread for a satisfying meal. This soup keeps well in the refrigerator for a few days and can also be a great option for freezing, making it perfect for busy weeknights or lunches on-the-go.
