Description

Hearty slow cooker lentil soup embodies comfort and warmth from Mediterranean kitchens. Robust ingredients meld together, creating a nourishing meal you’ll savor with each spoonful.


Ingredients

Scale
  • 1.5 cups / 300 grams dry lentils (green or brown, rinsed)
  • 6 cups vegetable broth
  • 1 can / 14 oz / 400 grams diced tomatoes
  • 1 onion, diced
  • 2 carrots, diced
  • 2 celery stalks, diced
  • 3 cloves garlic, minced
  • 2 cups fresh spinach or kale (optional)
  • 1 tsp cumin
  • 1 tsp smoked paprika
  • 0.5 tsp dried thyme
  • 0.5 tsp black pepper
  • 0.5 tsp salt (adjust to taste)
  • 1 bay leaf
  • Juice of 1 lemon

Instructions

  1. Preparation: Lightly coat slow cooker interior with cooking spray to prevent sticking and facilitate effortless cleanup.
  2. Base Layer: Layer dried lentils, onions, carrots, and celery evenly across the slow cooker bottom, creating a robust vegetable foundation.
  3. Liquid and Aromatics: Pour diced tomatoes and vegetable broth over vegetables, then sprinkle minced garlic, ground cumin, paprika, thyme, black pepper, and sea salt to develop a complex flavor profile.
  4. Herbal Infusion: Nestle a whole bay leaf into the mixture, allowing its subtle herbal essence to permeate the liquid during cooking.
  5. Slow Cooking Process: Cover and set slow cooker to low temperature for 6-7 hours or high temperature for 3-4 hours, allowing ingredients to transform and tenderize, with lentils becoming soft and vegetables melding together.
  6. Final Touch: In the last 5 minutes of cooking, fold in fresh leafy greens like spinach or kale, letting them gently wilt and integrate into the soup’s texture.
  7. Finishing and Serving: Remove bay leaf, stir in fresh lemon juice for brightness, then ladle into warm bowls and accompany with crusty artisan bread or a crisp side salad for a complete, nutritious meal.

Notes

  • Prevent Lentil Clumping: Rinse lentils thoroughly before adding to prevent sticking and ensure even cooking throughout the soup.
  • Boost Flavor Depth: Sauté onions, garlic, and vegetables briefly before adding to slow cooker to intensify their natural sugars and create a more complex taste profile.
  • Adjust Liquid Consistency: Keep extra vegetable broth nearby to adjust soup thickness if needed during cooking, as lentils absorb liquid differently.
  • Customize Dietary Needs: Easily convert to gluten-free by using gluten-free broth and checking seasoning labels; swap vegetables for low-carb alternatives like zucchini for keto-friendly version.
