This detox lentil soup is healthy, hearty, and made right in your slow cooker. It’s packed with protein-rich lentils, fiber-filled veggies, and anti-inflammatory spices to nourish your body and keep you full. Ideal for meal prep or a cozy, nutritious dinner.


Ingredients

  • 1 tablespoon olive oil

  • 1 medium yellow onion, diced

  • 2 ribs celery, chopped

  • 2 medium carrots, chopped

  • 3 cloves garlic, minced

  • 1 1/2 cups dry brown or green lentils, rinsed

  • 1 (15-ounce) can diced tomatoes, with juices

  • 1/2 teaspoon dried thyme

  • 1/2 teaspoon ground cumin

  • 1/2 teaspoon smoked paprika

  • 1/4 teaspoon turmeric (optional for extra detox benefit)

  • 1/4 teaspoon black pepper

  • 1/2 teaspoon salt, more to taste

  • 4 cups low-sodium vegetable broth

  • 2 cups water

  • 2 cups chopped kale or spinach

  • Juice of 1/2 lemon (for brightness)

 

  • Optional: red pepper flakes for heat, fresh parsley for garnish


Instructions

  • Prep the Base:
    Heat olive oil in a skillet over medium heat. Add onion, celery, and carrots. Sauté for 5–6 minutes until softened. Add garlic and cook 1 minute more.

  • Combine in Slow Cooker:
    Transfer sautéed veggies to your slow cooker. Add lentils, diced tomatoes, thyme, cumin, paprika, turmeric, salt, pepper, broth, and water. Stir to combine.

  • Cook:
    Cover and cook on Low for 8–9 hours or High for 4–5 hours, until lentils are tender.

  • Add Greens & Lemon:
    Stir in chopped kale or spinach and cook for another 5–10 minutes until wilted. Finish with a squeeze of lemon juice.

 

  • Serve:
    Taste and adjust seasoning. Ladle into bowls and garnish with parsley or red pepper flakes if desired.


Notes

  • Store leftovers in the fridge for up to 5 days, or freeze for up to 3 months.

  • Great with crusty bread or a sprinkle of Parmesan (optional for non-vegan diets).

 

  • Blend partially with an immersion blender for a thicker texture.
