Part 2: Ingredients & Preparation

🧄 Essential Ingredients for a Flavorful Lentil & Spinach Soup

This soup shines because of its simple, wholesome ingredients. Here’s what you’ll need for the best results:

  • Lentils (1 cup): Brown or green lentils work best for texture. Red lentils cook faster but break down more.
  • Fresh spinach (10 oz): Baby spinach is tender and cooks quickly. You can also use chopped mature spinach.
  • Carrots (2-3): Add sweetness and depth.
  • Yellow onion (1): Provides the flavor base when sautéed.
  • Garlic (3-4 cloves): For earthy, aromatic notes.
  • Diced tomatoes (2 x 15 oz cans): Adds acidity and umami.
  • Vegetable broth (5 cups): Use a rich broth to bring everything together.
  • Oregano & basil (2 tsp each): For Italian-inspired warmth.
  • Olive oil (2 tbsp): For sautéing and richness.
  • Lemon juice (2 tbsp): Brightens the flavors at the end.

Optional Add-ins:

  • Red chili flakes for spice
  • Ground cumin or turmeric for a Middle Eastern twist
  • Fresh parsley or cilantro for garnish

🥄 Lentil Basics: Which Ones to Use & How to Prep

Not all lentils are created equal. Here’s how to choose the right type:

  • Brown lentils: Most common, mildly earthy, hold their shape well.
  • Green lentils: Firmer and more peppery. Great for texture.
  • Red/yellow lentils: Cook fastest and become soft and creamy—ideal if you want a stew-like soup.

Do You Need to Soak Lentils?

Soaking is optional, but it can reduce cooking time and make digestion easier. If you choose to soak:

  • Rinse lentils under cold water.
  • Soak in a bowl of water for 2–8 hours.
  • Drain and rinse before adding to your soup.

Even without soaking, most lentils cook in 20–30 minutes—perfect for quick weeknight meals. For more on this, explore how to cook lentils perfectly via Bon Appétit.

❌ Common Mistakes to Avoid When Cooking Lentil & Spinach Soup

Even a simple soup can go wrong without the right technique. Here are some pitfalls to watch for:

➡️ Up next in Part 4: All your most frequently asked questions about lentil and spinach soup—answered!

Part 4: Frequently Asked Questions (FAQs)

❓ Do You Need to Soak Lentils Before Making Soup?

Soaking lentils before cooking is optional. While soaking can reduce cooking time and make lentils easier to digest, it’s not essential for soup. If you have time, soak for 2–4 hours. If not, simply rinse well and cook directly. Dried brown or green lentils typically take 20–30 minutes to become tender.

⏱️ How Long Should Lentils Cook in Soup?

It depends on the type of lentils. Brown and green lentils usually cook in 20–30 minutes without pre-soaking. Red lentils break down more quickly and are done in 15–20 minutes. Always taste to check doneness; they should be tender but not mushy unless you’re going for a creamy texture.

🥫 Can You Use Canned Lentils?

Yes! Canned lentils are a great time-saver. Just be sure to:

  • Rinse them well to remove excess salt or preservatives.
  • Reduce your broth by about 1–1.5 cups since canned lentils don’t absorb liquid like dried ones.
  • Add them during the last 10 minutes of cooking to warm through without overcooking.

🥄 What Type of Lentils Are Best for Soup?

  • Brown lentils: Classic choice, hold their shape well, mild flavor.
  • Green lentils: Slightly firmer and peppery—great for texture.
  • Red/yellow lentils: Softer, cook quickly, ideal for creamy or blended soups.

If you’re new to lentils, start with brown or green for best results in this recipe.

❄️ Can You Freeze Lentil and Spinach Soup?

Absolutely. Lentil soup freezes beautifully:

  • Let it cool completely before transferring to airtight containers.
  • Freeze for up to 3 months.
  • Reheat on the stovetop or microwave, adding a splash of broth or water if it thickens too much.

Pro Tip: Add spinach after reheating for a fresher texture, or undercook it slightly before freezing.

💪 What Can I Add for More Protein?

This soup already has a great base of plant protein from lentils. But for even more protein power, consider adding:

  • Chickpeas or white beans (canned or cooked)
  • Quinoa or farro for texture and nutrition
  • Tofu cubes or tempeh for a vegan boost

🍅 How Do I Make It Less Acidic?

If the tomatoes are a bit tangy or overpowering:

  • Add a pinch of sugar to balance the acid.
  • Use low-acid tomatoes or substitute part of the tomatoes with carrot puree or sweet potato.
  • Stir in coconut milk or cashew cream for smoothness and mild flavor.

🌱 Is It Vegan and Gluten-Free?

Yes! As long as you use vegetable broth and avoid gluten-containing toppings (like certain breads or croutons), this soup is naturally vegan and gluten-free. It’s also:

  • Nut-free (unless using cashew cream)
  • Low in fat and sugar
  • High in fiber, iron, and plant-based protein

📌 Key Takeaways from Part 4

  • Soaking lentils is optional; rinse well and cook directly for easy prep.
  • Canned lentils work great—just adjust liquid and cooking time.
  • Customize the soup’s acidity, texture, and protein with easy add-ins.
  • This soup is perfect for most dietary needs: vegan, gluten-free, and clean-eating friendly.
