Ingredients Overview

The beauty of this soup lies in its simple pantry staples, each bringing flavor, texture, and nutrition.

Lentils:

• Green lentils (also called French or brown-green lentils)
  These keep their shape and provide a tender, nutty texture. Avoid red lentils, which break down into a puree.

Vegetables:

• Onion, carrots, and celery – The base aromatics, also known as mirepoix.

• Garlic – Adds depth and aroma.

• Tomatoes – Use diced canned tomatoes for body and richness.

• Spinach or kale – Added at the end for a touch of green and freshness.

• Potatoes or zucchini (optional) – For more heartiness.

Broth & Seasonings:

• Vegetable broth – The base liquid; choose low-sodium for better control of seasoning.

• Olive oil – For sautéing and flavor.

• Bay leaves, thyme, oregano, cumin – These Mediterranean spices and herbs add earthy warmth.

• Salt and black pepper – To taste.

• Optional: A splash of lemon juice or vinegar at the end for brightness.

Step-by-Step Instructions

1. Sauté the Aromatics

• Heat 2 tablespoons olive oil in a large pot over medium heat.

• Add:

  • 1 chopped onion

  • 2 diced carrots

  • 1 teaspoon dried thyme

Let cook for 2 minutes to blend the flavors.

3. Simmer the Lentils

• Add:

  • 1 cup green lentils (rinsed)

  • 6 cups vegetable broth

4. Add Greens and Finish

• Always rinse lentils before cooking to remove dust or debris.

• For a thicker soup, blend 1–2 cups with an immersion blender and stir back in.
