  • 1 medium onion, diced

  • 2 tbsp olive oil

  • 2 cloves garlic, minced

  • 3 medium carrots, peeled and diced

  • 2 stalks celery, diced

  • 1 tsp ground turmeric

  • 1 tsp spice blend (e.g., cumin, coriander, smoked paprika)

  • 1.2 L vegetable broth or water

  • 75 g fresh spinach, roughly chopped

  • Juice of ½ lemon

  • Salt and freshly ground black pepper, to taste

  • Pinch of chili pepper flakes (optional)

  • 2 tbsp chopped fresh parsley or cilantro

• For the Spiced Croutons:

  • 3 slices sturdy bread, cut into 1–2 cm cubes

  • 2 tbsp olive oil

  • ½ tsp salt

  • ¼ tsp dried garlic powder

  • ½ tsp Italian herb blend (oregano, basil, thyme)

• Optional Garnishes:

  • Crumbled tofu cheese or feta

  • Extra chili flakes

Step-by-Step Cooking Directions

1. Prep Lentils: Drain the soaked lentils and set aside.

2. Sauté Onion: In a large pot, heat 2 tbsp olive oil over medium heat. Add the diced onion and fry for 5 minutes until soft and translucent.

3. Add Garlic: Stir in the minced garlic and cook for 1 minute, just until fragrant—avoid browning.

4. Cook Carrots & Celery: Add the diced carrots and celery. Sauté for 2–3 minutes, coating them in oil and allowing edges to soften.

5. Spice It Up: Sprinkle in the turmeric and your favorite spice blend. Stir thoroughly to toast the spices and coat the vegetables.

6. Add Lentils & Liquid: Stir in the drained lentils, then pour in the vegetable broth or water. Increase heat, cover, and bring to a gentle simmer. Cook for 15–20 minutes, uncovered, until lentils are tender and beginning to break down.

7. Prepare Croutons: While the soup simmers, preheat the oven to 180 °C (350 °F). Toss the bread cubes with 2 tbsp olive oil, salt, garlic powder, and Italian herbs. Spread in a single layer on a baking sheet and bake 10 minutes, turning once, until golden and crisp.

8. Finish the Soup: Once the lentils are soft, stir in the chopped spinach and let it wilt for 3–5 minutes. Season generously with salt, pepper, and, if you like heat, a pinch of chili flakes. Squeeze in the lemon juice for brightness.

9. Serve: Ladle the soup into bowls, top with spiced croutons, sprinkle with fresh parsley or cilantro, and add tofu cheese or extra chili flakes if desired.
