Ingredients Needed

For the base:

• 2 tbsp olive oil
• 1 onion, finely chopped (white, brown, or yellow all work)
• 2 garlic cloves, minced
• 1 large carrot, diced (about 1 ¼ cups)
• 2 celery stalks, diced (about 1 ¼ cups)

For the soup:

• 2 cups (about 400 g) dried green or brown lentils, rinsed well
• 1 can (400 g / 14 oz) crushed tomatoes
• 6 cups (1.5 liters) low-sodium vegetable or chicken broth
• ½ tsp ground cumin
• ½ tsp ground coriander
• 1 ½ tsp paprika
• 2 dried bay leaves

Finishing touches:

• 1 lemon (use both zest and juice for brightness)
• ¼ tsp salt and ¼ tsp black pepper, plus more to taste

How to Make Lentil Soup

• Start with the aromatics – In a large heavy-bottomed pot, warm the olive oil over medium heat. Add chopped onion and garlic, cooking for about 2 minutes until fragrant. This step builds the flavor foundation.
• Soften the vegetables – Stir in the carrot and celery. Cook slowly for 7–10 minutes, stirring occasionally, until the onion turns soft and sweet and the veggies are tender. Don’t rush—this is key for depth of flavor.
• Add the core ingredients – Mix in the lentils, crushed tomatoes, spices (cumin, coriander, paprika), bay leaves, and broth. Stir well to combine.

• Simmer gently – Bring the pot to a boil, then immediately reduce to a gentle simmer. Skim off any foam that rises to the top (this keeps the broth clear). Cover partially with a lid and cook for 35–40 minutes, or until the lentils are tender.
• Adjust the texture – Remove the bay leaves. Use an immersion blender for 2–3 quick pulses to slightly thicken the soup while keeping some lentils whole for texture. Alternatively, blend 2 cups in a blender, then return to the pot.

• Brighten the flavor – Stir in lemon zest and a squeeze of lemon juice just before serving. Taste and adjust with extra salt, pepper, or water to reach your desired consistency.

Serving and Storage Tips

• Serving: Garnish with fresh parsley or cilantro for a pop of color. Pair with warm, crusty bread spread with butter, garlic bread, or even pita chips.
• Storage: Store cooled soup in an airtight container in the fridge for up to 5 days.
• Freezing: This soup freezes beautifully for up to 3 months. Thaw overnight in the fridge before reheating.
• Reheating: Warm gently on the stovetop over medium heat, adding a splash of broth or water if it thickens too much.

Helpful Notes

• Lentil Options: Green or brown lentils hold their shape best. Red lentils can be used, but they’ll cook faster and give the soup a creamier texture.
• Make it Spicy: Add a pinch of chili flakes or cayenne pepper if you like a little heat.
• Extra Veggies: Spinach, kale, or zucchini can be stirred in toward the end for added nutrition.
• Protein Boost: Stir in shredded chicken or crumbled sausage for a heartier variation.

Frequently Asked Questions (FAQ)

Can I use red lentils instead of green or brown?

Yes, but keep in mind that red lentils cook much faster (about 20 minutes) and will break down, making the soup creamier.

How do I make this soup gluten-free?

This recipe is naturally gluten-free as long as your broth is certified gluten-free. Just pair it with gluten-free bread if desired.

Can I make this in a slow cooker?

Absolutely. Sauté the aromatics first, then transfer everything into a slow cooker and cook on low for 6–7 hours or high for 3–4 hours.

Is this recipe freezer-friendly?

Yes! Cool completely, then portion into freezer-safe containers. Thaw overnight in the fridge and reheat gently on the stovetop.

How thick should the soup be?

That’s up to you! Blend part of the soup for a thicker, creamier texture, or leave it chunky for a more rustic finish.
