Scale

Soup Ingredients

  • 1 1/2 cups red lentils
  • 4 large carrots, peeled and chopped
  • 1 red bell pepper, chopped
  • 2 celery stalks, chopped
  • 1/2 bunch kale (about 4 leaves, stems removed and chopped)
  • 2 russet potatoes, peeled and chopped
  • 1 jalapeño, chopped (optional)
  • 2 cloves garlic, pressed
  • 1/2 onion, chopped
  • 1 teaspoon salt
  • 1 teaspoon parsley
  • 1/2 teaspoon paprika
  • 1/2 teaspoon oregano
  • 1/2 teaspoon garlic salt
  • 1/4 teaspoon cayenne pepper
  • 6 1/2 cups vegetable stock


Instructions

  1. Prepare Ingredients: Begin by peeling, chopping, and pressing all the vegetables and garlic as specified in the ingredient list to ensure even cooking and balanced flavors.
  2. Add to Slow Cooker: Place all the prepped vegetables, red lentils, and seasonings into the slow cooker pot. Pour in the 6 1/2 cups of vegetable stock to cover the ingredients.
  3. Cook the Soup: Set the slow cooker on high for 5 hours or on low for 8 hours (low is preferred for better flavor melding). Stir the soup occasionally during cooking to prevent sticking and to combine flavors evenly.
  4. Adjust Consistency: If you prefer a thinner broth, add 1-2 cups more vegetable stock towards the end of cooking and stir well.
  5. Serve: Ladle the soup into bowls and optionally garnish with a dollop of sour cream and serve with crusty bread for a complete meal.

Notes

  • This soup is ideal for meal prepping and keeps well in the fridge for several days, making it perfect for lunches or quick dinners.
  • Adjust the level of spice by omitting the jalapeño or cayenne pepper if you prefer a milder soup.
  • Adding additional vegetable stock helps if you want a brothier soup consistency.
  • Use kale leaves with stems removed to avoid bitterness and tough texture.
  • Leftovers can be refrigerated or frozen for longer storage; reheat gently to preserve texture.
