Ingredients List

– 1½ cups dried brown or green lentils, rinsed and picked through
– 2 tablespoons olive oil
– 1 large yellow onion, diced (about 1½ cups)
– 2 medium carrots, diced (about 1 cup)
– 2 celery stalks, diced (about ¾ cup)
– 4 garlic cloves, minced
– 1 tablespoon tomato paste
– 1 teaspoon ground cumin
– 1 teaspoon dried thyme
– ½ teaspoon smoked paprika
– ¼ teaspoon red pepper flakes (optional)
– 1 bay leaf
– 6 cups vegetable or chicken broth
– 1 can (14.5 oz) diced tomatoes
– 2 cups fresh spinach or kale, roughly chopped (optional)
– 2 tablespoons fresh lemon juice
– Salt and freshly ground black pepper to taste
– Fresh parsley for garnish (optional)

Step-by-Step Instructions

1. Prepare the lentils: Rinse the lentils in a fine-mesh sieve under cold running water. Pick through them to remove any stones or debris. Set aside.

2. Sauté the aromatics: Heat olive oil in a large pot or Dutch oven over medium heat. Add the diced onion, carrots, and celery. Cook, stirring occasionally, until the vegetables begin to soften, about 5-7 minutes.

3. Add the garlic and spices: Stir in the minced garlic, tomato paste, cumin, thyme, smoked paprika, and red pepper flakes (if using). Cook until fragrant, about 1 minute.

4. Incorporate the lentils: Add the rinsed lentils to the pot and stir to coat them with the aromatic mixture. This easy lentil soup recipe becomes incredibly flavorful when you allow the lentils to toast slightly with the spices before adding liquid, making it a truly quick lentil soup with depth of flavor.

5. Add liquids: Pour in the broth and diced tomatoes with their juice. Add the bay leaf and stir to combine everything.

6. Simmer: Bring the mixture to a boil, then reduce heat to maintain a gentle simmer. Cover partially with a lid and cook until the lentils are tender but not mushy, about 25-30 minutes.

7. Add greens (if using): If you’re including spinach or kale, stir it in during the last 5 minutes of cooking until just wilted.

8. Finish with acid: Remove the pot from heat and stir in the fresh lemon juice. Remove the bay leaf.

9. Season: Taste and adjust seasoning with salt and pepper as needed.

10. Serve: Ladle into bowls and garnish with fresh parsley if desired.

Tips & Variations

Flavor Enhancements:

Ingredient Substitutions:
– Red lentils can be used for a creamier texture but reduce cooking time to about 15 minutes
– Use sweet potatoes instead of carrots for a slightly sweeter flavor
– Replace spinach with any sturdy greens like Swiss chard or collards

Dietary Adaptations:

Alternative Cooking Methods:

Common Mistakes to Avoid

1. Not rinsing lentils: Skipping this step can leave grit in your soup and prevent even cooking.
Solution: Always rinse lentils thoroughly under cold water.

2. Overcooking the lentils: This results in a mushy texture.
Solution: Start checking for doneness at the 20-minute mark.

3. Under-seasoning: Lentils need proper seasoning to shine.
Solution: Taste and adjust seasonings near the end of cooking.

4. Skipping the acid component: Lemon juice or vinegar brightens the flavors.
Solution: Always add some form of acid at the end of cooking.

5. Adding salt too early: This can make lentils tough.
Solution: Add most of your salt in the final 10 minutes of cooking.

Storage & Reheating Tips

Refrigeration:
– Store cooled soup in airtight containers for up to 5 days in the refrigerator.
– The flavor often improves after a day as ingredients meld together.

Freezing:
– Freeze in portion-sized containers for up to 3 months.
– Leave a half-inch space at the top to allow for expansion.
– Thaw overnight in the refrigerator before reheating.

Reheating:
– Stovetop: Warm over medium-low heat, stirring occasionally and adding a splash of broth if needed.
– Microwave: Heat in 1-minute intervals, stirring between each until hot throughout.
– Add fresh herbs or a squeeze of lemon after reheating to revive flavors.

FAQs

Can I use red lentils instead of brown or green?
Yes, you can use red lentils, but they cook much faster (about 15-20 minutes) and will create a creamier, less textured soup as they tend to break down more during cooking.

Is this soup freezer-friendly?
Absolutely! This soup freezes exceptionally well for up to 3 months. Allow it to cool completely before transferring to freezer-safe containers, leaving some space for expansion.

How can I make this soup thicker or thinner?
For a thicker soup, you can puree a portion of the finished soup and return it to the pot, or add less broth initially. For a thinner consistency, simply add more broth until you reach your desired texture.

Can I make this in an Instant Pot?
Yes! Use the sauté function for the vegetables and spices, then add remaining ingredients and cook on high pressure for 10 minutes with a natural pressure release.

What can I serve with lentil soup?
Crusty bread, a simple green salad, or grilled cheese sandwiches all pair beautifully with this soup. For a heartier meal, serve over a small portion of cooked rice or quinoa.
