Ingredients
- 2 tablespoons olive oil
- 1 large yellow onion, diced
- 2 medium carrots, peeled and diced
- 2 celery stalks, diced
- 4 cloves garlic, minced
- 1 1/2 teaspoons ground cumin
- 1 teaspoon smoked paprika
- 1/2 teaspoon ground coriander
- 1/2 teaspoon dried thyme
- 1/4 teaspoon crushed red pepper flakes (optional)
- 1 can (14.5 ounces) diced tomatoes, with juice
- 1 1/2 cups dried brown or green lentils, rinsed and drained
- 6 cups low-sodium vegetable broth
- 2 bay leaves
- 1 teaspoon salt, plus more to taste
- 1/2 teaspoon freshly ground black pepper
- 2 cups chopped fresh spinach or kale (optional)
- 1 to 2 tablespoons lemon juice (from 1 lemon)
- Chopped fresh parsley, for garnish (optional)
Instructions
- Prep the vegetables. Dice the onion, carrots, and celery. Mince the garlic. Rinse and drain the lentils thoroughly.
- Sauté aromatics. In a large soup pot or Dutch oven, heat the olive oil over medium heat. Add the onion, carrots, and celery. Cook, stirring occasionally, until the vegetables are softened and the onion is translucent, about 7–8 minutes.
- Add garlic and spices. Stir in the garlic, cumin, smoked paprika, coriander, thyme, and red pepper flakes (if using). Sauté for 1–2 minutes, stirring constantly, until fragrant.
- Add tomatoes and lentils. Pour in the diced tomatoes with their juice. Add the rinsed lentils and stir to combine.
- Add broth and seasonings. Pour in the vegetable broth, add the bay leaves, salt, and black pepper. Stir well and bring the mixture to a boil over high heat.
- Simmer the soup. Once boiling, reduce the heat to low and partially cover the pot with a lid. Simmer for 30–35 minutes, stirring occasionally, until the lentils are tender but not mushy.
- Add greens (optional). If using spinach or kale, stir it in during the last 5 minutes of cooking, just until wilted and bright green.
- Finish with lemon. Remove the bay leaves and stir in lemon juice to brighten the flavors. Taste and adjust seasoning with additional salt, pepper, or lemon juice as desired.
- Serve hot. Ladle the soup into bowls and garnish with chopped fresh parsley if desired. Serve with crusty bread or a side salad.
Tips
- Lentil choice: Brown or green lentils hold their shape best; red lentils will break down more and create a creamier texture, but the cooking time is shorter (about 20–25 minutes).
- Substitutions: Swap spinach for kale, or use Swiss chard. If you don’t have smoked paprika, regular paprika works, though you’ll lose the smoky nuance.
- Flavor boosters: Add a Parmesan rind while simmering for a savory depth (remove before serving), or finish with a drizzle of good olive oil.
- Common mistakes: Don’t skip rinsing the lentils, as this removes debris and excess starch. Avoid overcooking, which can turn the lentils mushy.
Serving Suggestions
This lentil soup is incredibly versatile. For a complete meal, pair it with crusty sourdough or whole-grain bread for dipping. A simple green salad with a lemony vinaigrette makes a fresh side. For extra protein, top each bowl with a spoonful of Greek yogurt or a sprinkle of feta cheese. If you enjoy heat, offer hot sauce or red pepper flakes at the table. For a heartier meal, serve the soup over cooked brown rice or quinoa, or alongside roasted vegetables.
Variations
- Spiced Lentil Soup: Add 1/2 teaspoon ground turmeric and a pinch of cinnamon for a Middle Eastern spin. Garnish with fresh cilantro.
- Italian-Style: Replace cumin and paprika with 1 teaspoon Italian seasoning. Add a handful of chopped sun-dried tomatoes and finish with grated Parmesan.
- Hearty Vegetable: Add 1 diced potato or sweet potato along with the carrots and celery, or stir in 1 cup of frozen peas during the last 5 minutes.
- Protein-Packed: Stir in 1–2 cups of cooked, shredded chicken or turkey for a meaty version, or add cooked sausage slices for extra flavor.
- Creamy Lentil Soup: After simmering, use an immersion blender to partially puree the soup for a thicker, creamier texture—blend as much or as little as you like.
Storage and Reheating
Let the soup cool to room temperature before storing. Transfer to airtight containers and refrigerate for up to 5 days. Lentil soup thickens as it sits; add a splash of water or broth when reheating to reach your desired consistency. To reheat, warm on the stovetop over medium heat, stirring occasionally, until hot—about 5–7 minutes. Alternatively, microwave individual portions in a microwave-safe bowl, covered with a loose lid, for 2–3 minutes, stirring halfway through.
For longer storage, lentil soup freezes well. Portion into freezer-safe containers, leaving an inch of space at the top. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating, or gently reheat from frozen over low heat, adding more liquid as needed.
Frequently Asked Questions
- Do I need to soak lentils before making soup?
- No, lentils do not require soaking before cooking. Rinsing them thoroughly is sufficient. Soaking is optional and can slightly reduce cooking time, but it is not necessary for this recipe.
- Can I use canned lentils instead of dried?
- Yes, you can substitute canned lentils (drained and rinsed) for dried. Add them during the last 10 minutes of cooking since they are already cooked. Reduce the broth by about 1 cup to avoid thinning the soup.
- How do I prevent the lentils from getting mushy?
- Keep an eye on the soup after 25 minutes of simmering, as cooking times can vary. Brown and green lentils hold their shape best. Avoid overcooking and always use a gentle simmer rather than a rapid boil.
- Is this lentil soup gluten-free?
- Yes, the basic recipe is naturally gluten-free if you use gluten-free broth. Always check the labels on store-bought broth and canned tomatoes to ensure no gluten-containing additives are present.
- Can I make this soup in a slow cooker?
- Absolutely. Sauté the vegetables and spices as directed, then transfer everything to a slow cooker. Cook on low for 6–8 hours or high for 3–4 hours, until the lentils are tender. Add greens and lemon juice just before serving.
- What’s the best way to add extra flavor?
- For more depth, consider adding a splash of balsamic vinegar, a dash of Worcestershire sauce (if not vegetarian), or a pinch of smoked salt at the end. Fresh herbs like thyme or parsley stirred in before serving also brighten the flavors.
