Ingredients

Scale

Main Vegetables:

  • 1.5 cups (300 grams) dry lentils (green or brown, rinsed)
  • 1 onion, diced
  • 2 carrots, diced
  • 2 celery stalks, diced
  • 3 cloves garlic, minced

Liquid and Canned Ingredients:

  • 1 can (14 ounces/400 grams) diced tomatoes
  • 6 cups vegetable broth
  • Juice of 1 lemon

Herbs and Seasonings:

  • 1 teaspoon cumin
  • 1 teaspoon smoked paprika
  • 0.5 teaspoon dried thyme
  • 0.5 teaspoon black pepper
  • 0.5 teaspoon salt (adjust to taste)
  • 1 bay leaf
  • 2 cups fresh spinach or kale (optional)

Instructions

  1. Gather all ingredients and prepare the slow cooker by lightly coating the interior with cooking spray to prevent sticking and ensure easy cleanup.
  2. Create a flavor foundation by combining dried lentils, finely chopped onions, diced carrots, and thinly sliced celery into the slow cooker, arranging them as an even base layer.
  3. Mince fresh garlic cloves and sprinkle them over the vegetable mixture, then pour in diced tomatoes and vegetable broth to create a rich, aromatic liquid base.
  4. Enhance the soup’s depth by adding ground cumin, sweet paprika, dried thyme, freshly cracked black pepper, and sea salt to infuse complex flavors throughout the cooking process.
  5. Drop a whole bay leaf into the mixture, which will impart a subtle herbal essence and can be easily removed before serving.
  6. Cover the slow cooker and set to low temperature, allowing the ingredients to gently simmer and meld together for 6-7 hours, or alternatively use high temperature for 3-4 hours until lentils become tender and vegetables soften.
  7. During the final moments of cooking, introduce fresh leafy greens like spinach or kale, letting them wilt and integrate into the soup’s texture for an additional 5 minutes.
  8. Remove the bay leaf and brighten the soup’s flavor profile by stirring in fresh lemon juice, which will add a subtle tangy note.
  9. Ladle the steaming soup into warm bowls, pairing with crusty artisan bread or a crisp side salad for a complete, nourishing meal.

Notes

  • Rinse lentils thoroughly before adding to the slow cooker to remove any debris and ensure a cleaner, fresher taste.
  • Choose green or brown lentils for this recipe, as they hold their shape better during long cooking times and provide a heartier texture.
  • Add spinach or kale in the last few minutes of cooking to preserve their vibrant color and nutritional value, preventing them from becoming overly wilted.
  • For a protein boost, consider stirring in cooked shredded chicken or crumbled plant-based sausage just before serving, making the soup more filling.
  • Make this soup gluten-free by ensuring your vegetable broth is certified gluten-free and serving with gluten-free bread options.
  • Enhance the soup’s depth of flavor by toasting cumin and paprika in a dry pan for 30 seconds before adding to the slow cooker, which intensifies their aromatic qualities.
  • Store leftovers in airtight containers for up to 5 days, noting that the soup’s flavors will continue to develop and become more robust over time.
