How to Make Lentil Soup

Step 1: Sauté the Aromatics

Heat olive oil in a large pot over medium heat. Add chopped onion, carrots, and celery, and cook until softened and fragrant. Stir in minced garlic and cook for another minute.

Step 2: Add the Tomatoes and Herbs

Pour in the crushed tomatoes and stir well. Add the bay leaf, thyme, salt, and pepper, and let everything simmer for a few minutes to deepen the flavor.

Step 3: Stir in Lentils and Broth

Add the lentils and pour in the vegetable broth. Bring to a boil, then reduce heat and simmer uncovered for about 25-30 minutes, or until the lentils are tender.

Step 4: Finish and Adjust

Remove the bay leaf. Add a splash of lemon juice, adjust seasoning to taste, and stir in any greens if using. Let them wilt gently in the hot soup.

Step 5: Serve and Enjoy

Ladle into bowls, garnish with fresh herbs if desired, and serve hot with your favorite bread.

Pro Tips for Making the Recipe

• Use Fresh Garlic and Onion: These simple ingredients do heavy lifting in flavor — use fresh, not powdered, for the best results.
• Rinse Lentils Before Cooking: This helps remove any debris and makes for a cleaner flavor.
• Simmer Gently: Let the soup cook on low to let the flavors really meld. Rushing it on high heat can break down the veggies too quickly.
• Don’t Skip the Lemon: Just a little lemon juice at the end makes a huge difference. It brightens the whole soup.

How to Serve

This lentil soup is a complete meal on its own, but it pairs beautifully with a few extras:

With Bread:

Serve with crusty sourdough, garlic toast, or warm pita to soak up every last bit.

With Salad:

Pair with a simple green salad or cucumber yogurt salad for a refreshing contrast.

As a Side:

Serve a smaller portion alongside grilled vegetables, sandwiches, or roasted chicken for a more complete spread.

Make Ahead and Storage

Storing Leftovers

Let the soup cool completely before storing in airtight containers. It will keep in the refrigerator for up to 5 days. The flavors actually deepen overnight, making it even more delicious the next day.

Freezing

This soup freezes beautifully. Portion into freezer-safe containers and freeze for up to 3 months. Thaw overnight in the fridge for best texture.

Reheating

Reheat on the stovetop over medium heat, adding a splash of water or broth to loosen as needed. You can also reheat in the microwave in 1-2 minute bursts.

FAQs

Can I use canned lentils instead of dried?
Yes, you can, but reduce the cooking time since canned lentils are already cooked. Add them in the last 10 minutes so they don’t turn mushy.

Is this soup gluten-free?
Absolutely! All the ingredients in this lentil soup are naturally gluten-free. Just double-check your broth and any store-bought add-ins to be sure.

How can I make this soup more filling?
You can bulk it up by adding cooked rice, quinoa, or small pasta, or even top it with a poached egg or shredded chicken.

Can I make this in a slow cooker?
Yes, just sauté the aromatics first, then transfer everything to the slow cooker and cook on low for 6-8 hours or high for 3-4 hours, until the lentils are tender.
