2. The Health Power of Lentils and Spinach

Lentils: The Protein Powerhouse

Lentils are a staple in many cultures for good reason. They are low in fat, rich in plant-based protein, and loaded with dietary fibre, which aids digestion and stabilises blood sugar levels. Just one cup of cooked lentils provides:

• Around 18g of protein
• 15g of fibre
• 90% of your daily folate requirement

They’re also a great source of iron, magnesium, and potassium—key nutrients for maintaining energy and heart health.

Spinach: The Green Superfood

Spinach enhances this dish with freshness and nutrition. It’s high in vitamins A, C, and K, plus folate and iron. Spinach supports bone strength, immune function, and glowing skin. When stirred into a hot pot of soup, it wilts beautifully, adding colour, texture, and subtle sweetness.

3. Key Ingredients

Let’s break down the ingredients that make this soup flavourful and wholesome.

Core Ingredients

• Lentils (1 cup): Red or brown lentils work best; red gives a creamy texture, brown adds more bite.
• Onion (1 large): Adds sweetness and body.
• Garlic (4 cloves): For a savoury, aromatic base.
• Ginger (1 tbsp grated): Brightens the flavour and aids digestion.
• Tomatoes (2 medium or 1 can diced): Adds tanginess and depth.
• Spinach (2 cups fresh or 1 cup frozen): Stirred in at the end for freshness.

Spices

• Cumin seeds (1 tsp): Toasted for warmth.
• Ground turmeric (½ tsp): Anti-inflammatory and golden in colour.
• Coriander powder (1 tsp): Earthy and citrusy undertone.
• Smoked paprika (½ tsp): For subtle heat and smokiness.
• Chilli flakes (optional, ¼ tsp): Add a kick if you like it spicy.

Liquids

• Vegetable stock (4 cups): The base that brings it all together.
• Coconut milk (½ cup, optional): For a creamy finish.

Extras

• Lemon juice (1 tbsp): To brighten up the flavours.
• Salt and pepper: To taste.
• Olive oil (1 tbsp): For sautéing.

4. Step-by-Step Cooking Instructions

Step 1: Sauté the Aromatics

Heat olive oil in a large pot over medium heat. Add cumin seeds and toast until they start to pop—this releases their earthy aroma. Next, add chopped onions, garlic, and ginger. Sauté for 4–5 minutes until soft and golden.

Step 2: Add the Spices

Stir in turmeric, coriander powder, and smoked paprika. Toasting the spices for a minute helps deepen their flavour before adding liquid ingredients.

Step 3: Add Lentils and Tomatoes

Add rinsed lentils and diced tomatoes. Stir well so the lentils get coated with the spiced mixture. This helps build a rich base for the soup.

Step 4: Pour in Stock

Add vegetable stock and bring it to a boil. Once boiling, reduce the heat to low and simmer uncovered for 25–30 minutes. Stir occasionally to prevent sticking.

Step 5: Add Spinach and Finish

When the lentils are tender and the soup has thickened, stir in the spinach and let it wilt for 2–3 minutes. Add salt, pepper, and lemon juice. For creaminess, stir in coconut milk.

Step 6: Serve Hot

Ladle the soup into bowls, garnish with fresh coriander or a drizzle of olive oil, and enjoy with crusty bread or a side of brown rice.

5. Cooking Tips and Variations

Cooking Tips

• Soaking lentils: Not mandatory, but soaking them for 30 minutes reduces cooking time.
