Ingredients for Easy Vegetarian Lentil Soup with Spinach

Core Ingredients

To make a rich and flavorful soup, you’ll need:

• Lentils: Brown or green lentils are best if you want them to hold their shape. Red lentils will give the soup a creamier texture.

• Spinach: Fresh spinach is great, but frozen spinach works just as well.

• Onion, garlic, carrots, celery: The classic base for most soups, creating a savory flavor.

• Tomatoes: Canned diced or crushed tomatoes add acidity and depth.

• Vegetable broth: A good broth gives the soup richness.

• Olive oil, herbs, and spices: Think thyme, cumin, paprika, bay leaf, salt, and pepper.

Optional Additions

• Potatoes or sweet potatoes for extra comfort.

• Coconut milk if you like a creamy finish.

• Red pepper flakes or cayenne for a spicy kick.

• Fresh parsley or cilantro for garnish.

Nutritional note: Lentils are loaded with protein, fiber, and iron, while spinach boosts your meal with vitamin K, antioxidants, and more iron—making this soup a powerhouse of nutrients.

Step-by-Step Instructions for Vegetarian Lentil Soup with Spinach

Step 1 – Prep the Vegetables

Start by chopping your onion, carrots, celery, and garlic. A sharp knife and a little patience here will make your soup taste fresher and more flavorful.

Step 2 – Sauté the Aromatics

In a large pot, heat olive oil over medium heat. Add onion, carrots, celery, and garlic. Sauté until they soften and the kitchen fills with that mouthwatering aroma.

Step 3 – Add Lentils and Broth

Pour in the lentils, broth, tomatoes, and seasonings. Stir everything together, bring the mixture to a boil, then reduce to a simmer. Let it cook gently until the lentils are tender.

Step 4 – Add Spinach

Once the lentils are cooked, stir in the spinach. Fresh spinach wilts in seconds, and frozen spinach blends seamlessly into the broth. Adjust the seasoning to taste.

Step 5 – Serve

Ladle the soup into bowls, garnish with fresh herbs, or squeeze in a little lemon juice to brighten the flavors. Pair it with crusty bread, and you’ve got a meal that feels like home.

Tips for the Best Vegetarian Lentil Soup with Spinach

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

• Use broth instead of water for a richer, deeper flavor.

• Add spinach at the very end so it stays vibrant and fresh.

• If you’re using red lentils, keep in mind that they cook faster and will give you a creamier texture.

• Remember: this soup thickens as it sits. When reheating, simply add a splash of broth or water to loosen it up.
