Red Lentil Soup With Crispy Pita Croutons & Cilantro Topping

If you love soups this time of year and feel like your soup rotation could use something new, this red lentil soup is such a good one to add.

It’s a one-pot, low-effort kind of recipe that comes together fast, uses simple ingredients, and somehow tastes like it took much longer than it actually did. Red lentils are doing a lot of the heavy lifting here – they cook quickly, turn beautifully creamy, and bring that earthy, comforting flavor that makes a soup feel like real food.

What makes this soup special for me is the balance

You’ve got red lentils, sweet potato, pumpkin, and just a touch of cumin for warmth and that subtle Mediterranean, Middle Eastern vibe. Everything is cut small so it cooks evenly and quickly, and the soup is only partially blended, so you still get texture. Some veggies melt into the soup, others stay in soft little cubes that are honestly the best part.

And then there are the toppings. A fresh cilantro, garlic, and lemon blend, plus crispy baked pita strips. They’re optional, but once you try them, you’ll never want to skip them. Together, they turn this into a soup you could absolutely serve to guests – not a basic weekday bowl (even though it is perfect for weekdays too).

For the soup:

• Red lentils – 250 g, rinsed well
• Pumpkin – about 300 g, peeled and diced
• Sweet potatoes – 2 medium (about 300 g), diced
• Onion – 1 medium white or yellow (about 200 g), finely diced
• Celeriac – 70 g, finely diced
  • or 1 celery stalk, very finely chopped
• Olive oil – 2 tablespoons
• Ground cumin – ½ teaspoon
• Salt and black pepper, to taste
• Water or stock – 1½ liters
  • water, vegetable stock, chicken stock, or water with bouillon all work

The Toppings (Highly Recommended)

Cilantro Lemon Topping

• 1 garlic clove
• ½ bunch fresh cilantro (mostly leaves)
• ¼ cup olive oil
• 1 tablespoon lemon juice
• Zest of 1 lemon
• Salt, to taste
• Optional: fresh green chili, to taste

Blend everything in a food processor until smooth.

Crispy Pita Croutons

• Pita bread, cut into thick strips
• Olive oil
• Flaky salt

Bake at 180°C / 350°F for 10–15 minutes, until golden and crisp. Keep an eye on them – thickness and ovens vary.

How to Make Red Lentil Soup

1. Heat the olive oil in a large pot over medium heat.
2. Add the onion, celeriac (or celery), and sweet potato. Cook for about 10 minutes, stirring occasionally, until softened.
3. Add the pumpkin cubes and rinsed red lentils.
4. Season with cumin, salt, and pepper.
5. Pour in the water or stock and bring to a boil.
6. Taste and adjust salt – this is your first seasoning check.
7. Lower to a simmer and cook for 25–30 minutes, until everything is very tender.
8. Blend the soup partially using an immersion blender. You want it creamy but still chunky, with soft cubes throughout.
9. Taste again and adjust seasoning after blending.

Serve hot with pita croutons and the cilantro topping on top.

How to Make the Cilantro Topping

This is what really lifts the soup and gives it that fresh, punchy contrast.

• Add the garlic, fresh cilantro (mostly leaves), olive oil, lemon juice, lemon zest and salt to a food processor.
• Blend until completely smooth.
• Taste and adjust – more lemon for brightness, more olive oil if you want it looser.

If you like heat, add fresh green chili and blend again.
Serve it on top of the soup and let everyone add as much or as little as they like.

How to Make Crispy Pita Croutons

These are simple but make a huge difference in texture.

• Cut the pita bread into thicker strips or rough pieces and toss with olive oil and a pinch of flaky salt.
• Spread in a single layer on a baking tray.
• Bake at 180°C / 350°F for 10–15 minutes, until golden and crisp.

Keep an eye on them – baking time depends on the thickness of the pita and your oven.
Let them cool slightly before serving so they stay crunchy.

Tips for the Best Red Lentil Soup

• Rinse the lentils well – this improves both flavor and texture.
• Cut the vegetables small so everything cooks evenly and quickly.
• Season in stages – once before simmering and again after blending.
• Blend only partially – that mix of creamy base and soft chunks is what makes this soup special.
• Adjust thickness after blending – add a bit more hot water or stock if needed.
• Red lentils cook fast and don’t need soaking, which is why this soup is such a good weeknight option.

Storage & Reheating

This soup keeps well in the fridge for up to 4 days in an airtight container.

Reheat gently on the stove, adding a splash of water or stock if it thickens. The flavors actually deepen after a day, so it’s great for make-ahead lunches.

Store toppings separately and add just before serving.
