Recipe Card / Summary Box

Clear Ingredient List

Here’s what you’ll need to make this flavorful Lentil and Spinach Soup:

Base Ingredients:

• 1 tablespoon olive oil
• 1 large onion, diced
• 3 garlic cloves, minced
• 2 carrots, peeled and chopped
• 2 celery stalks, chopped
• 1 teaspoon ground cumin
• 1 teaspoon smoked paprika
• 1 teaspoon dried thyme
• 1½ cups dried green or brown lentils (rinsed)
• 6 cups vegetable broth (low sodium preferred)
• 1 bay leaf
• Salt and black pepper to taste

Flavor Boosters (optional but recommended):

• Juice of ½ lemon (brightens the soup)
• 1 tablespoon tomato paste (adds depth)
• 1 teaspoon chili flakes (for heat)
• ½ cup canned coconut milk (for a creamy twist)

Final Add-ins:

• 4 cups fresh spinach, chopped
• 2 tablespoons fresh parsley or cilantro, chopped
• 1 tablespoon olive oil (drizzle for serving)

Step-by-Step Instructions

Step 1: Sauté Aromatics for a Flavorful Base

Start by heating 1 tablespoon of olive oil in a large soup pot or Dutch oven over medium heat. Add 1 chopped onion, 2 chopped carrots, and 2 stalks of chopped celery.

Why this matters: These ingredients create a flavor foundation. When sautéed properly, they add natural sweetness and umami to your Lentil and Spinach Soup, eliminating the need for artificial enhancers.

Sauté for 5–6 minutes, stirring occasionally, until the vegetables begin to soften and the onions are slightly golden.

Step 2: Add Garlic and Ground Spices

Next, stir in 3 minced garlic cloves, 1 teaspoon ground cumin, 1 teaspoon smoked paprika, and 1 teaspoon dried thyme.

Tip: Let the spices toast in the hot oil for 30–60 seconds. This step intensifies their aroma and infuses the oil, enhancing the overall depth of your Lentil and Spinach Soup.

Step 3: Stir in Lentils and Broth

Add 1½ cups of rinsed green or brown lentils to the pot, followed by 6 cups of vegetable broth (choose low-sodium to control salt levels). Toss in 1 bay leaf.

Bring the mixture to a boil over high heat. Once it starts bubbling, reduce the heat to low and let it simmer uncovered for 25–30 minutes, or until the lentils are tender.

Why this matters: Simmering allows the lentils to slowly absorb the broth, helping your Lentil and Spinach Soup develop a rich, well-rounded flavor.

Step 4: Add Optional Flavor Boosters

To make your Lentil and Spinach Soup stand out, stir in:

• 1 tablespoon tomato paste (adds savory umami)
• 1 teaspoon chili flakes (adds a gentle heat)
• Juice of ½ lemon (brightens the flavor)
• ½ cup canned coconut milk (adds creaminess without dairy)

Simmer for 5 additional minutes, letting the soup absorb these final layers of flavor.

These additions help balance the earthiness of lentils and the mildness of spinach, creating a more exciting taste profile.

Step 5: Add the Spinach and Fresh Herbs

Now, add 4 cups of chopped fresh spinach and 2 tablespoons of chopped parsley or cilantro. Stir everything together and cook for 2–3 minutes, just until the spinach wilts.

Spinach cooks very quickly, so don’t overdo it. You want it tender but still vibrant. Fresh herbs finish your Lentil and Spinach Soup with a fresh pop of flavor and aroma.

Step 6: Taste and Adjust

Before serving, taste your Lentil and Spinach Soup and adjust the seasoning:

• Add more salt if needed
• A pinch of black pepper can sharpen the flavor
• More lemon juice can lift a flat soup
• A dash of chili flakes can bring extra warmth

This final tasting step ensures your soup hits all the right flavor notes.

Step 7: Serve and Enjoy

Ladle the hot Lentil and Spinach Soup into bowls. For an added finishing touch, drizzle with a little olive oil or sprinkle with red pepper flakes or nutritional yeast.

Serve with:

• Crusty bread
• Brown rice
• Garlic toast
• A light side salad

Whether you’re enjoying it for dinner, lunch, or meal prep, this soup is wholesome, satisfying, and easy to love.

Cooking Tips and Variations

Tip 1: Layer the Flavor

Sautéing spices like cumin and paprika with garlic helps create a rich base flavor. Don’t skip this step.

Tip 2: Add Creaminess Without Cream

A splash of coconut milk creates a silky texture while keeping the recipe dairy-free. You can also blend half the soup for a naturally thicker consistency.

Tip 3: Brighten with Acid

Lemon juice added at the end lifts all the flavors and balances the earthy lentils.

Tip 4: Don’t Under salt

Lentils soak up seasoning. Taste and adjust salt at the end for best results.

Tip 5: Herbs Make a Difference

Fresh parsley or cilantro adds a burst of freshness. Try basil for an Italian twist or dill for something different.

Variations to Try:

• Indian-Inspired: Add curry powder, turmeric, and ginger. Serve with rice.
• Mediterranean Style: Use oregano, lemon zest, and serve with a dollop of hummus.
• Spicy Version: Add harissa or chopped jalapeños for heat.
