Ingredients
Soup:
- 1–2 tbsp olive oil or avocado oil
- 3 large carrots, peeled and sliced
- 2 celery stalks, chopped
- 1 medium yellow onion, diced
- 4 garlic cloves, minced
- 6 cups vegetable stock
- 1½ cups red lentils, rinsed
- 2 bay leaves
- ½ tsp turmeric
- 1 tsp cumin
- ½ tsp black pepper
- 1 tsp kosher salt
- Juice of 1 lemon (~5 tbsp)
- 1 tsp lemon zest
- Optional: 1–2 cups spinach or kale
Garnish:
- Fresh parsley or cilantro
- Freshly cracked black pepper
Step-by-Step Instructions
- Sauté Vegetables:
Heat oil in a large stockpot over medium heat. Add onions, celery, and carrots, cooking 3–4 minutes until softened. Add garlic and cook 1 more minute until fragrant. - Simmer Lentils:
Pour in the vegetable stock. Stir in red lentils, bay leaves, turmeric, and cumin. Bring to a boil over medium-high heat, then reduce heat to medium-low, cover, and simmer 12–15 minutes until lentils are tender. - Add Lemon:
Remove the lid and stir in lemon juice, lemon zest, salt, and pepper. - Blend (Optional):
For a smoother texture, blend 2 cups of the soup and return it to the pot, or use an immersion blender to partially blend for a creamy yet chunky consistency. - Add Greens:
Stir in spinach or kale and cook 2–3 minutes until wilted. Adjust seasoning with more salt and pepper if needed. - Serve:
Ladle into bowls and garnish with parsley or cilantro and freshly cracked black pepper. Enjoy warm!
Storage and Freezing
- Refrigerate: Store in an airtight container in the fridge for up to 5 days.
- Freeze: Transfer cooled soup to freezer-safe containers or bags for up to 6 months. Lay bags flat to save space. Thaw overnight in the fridge before reheating.
- Reheat: Warm gently on the stovetop over medium heat, adding a splash of broth or water if needed.
Tips & Variations
- Add More Vegetables: Stir in zucchini, bell pepper, or tomatoes for extra flavor.
- Swap Lentils: Red, green, or yellow lentils all work; red lentils cook fastest.
- Boost Protein: Add chickpeas or white beans for extra plant-based protein.
- Adjust Flavors: For a spicier kick, add a pinch of cayenne or smoked paprika.
