Step-by-Step Recipe Instructions

Creating the best lentil soup with spinach and lemon is refreshingly straightforward. Follow these simple steps for soup perfection:

Step 1: Heat 2 tablespoons olive oil in a large pot or Dutch oven over medium heat. Add 1 diced onion, 2 diced carrots, and 2 diced celery stalks. Cook for 5-7 minutes until vegetables begin to soften.

Step 2: Add 4 minced garlic cloves and cook for 30 seconds until fragrant. Stir in 1 teaspoon ground cumin, 1/2 teaspoon ground coriander, and 1/2 teaspoon smoked paprika, cooking for another 30 seconds to bloom the spices.

Step 3: Add 1 1/2 cups rinsed lentils, 6 cups vegetable broth, 2 bay leaves, 1 teaspoon salt, and 1/2 teaspoon black pepper. Bring to a boil, then reduce heat to maintain a gentle simmer. Cover partially and cook for 25-30 minutes until lentils are tender but still hold their shape.

Step 4: Stir in 4 cups fresh spinach (about 4 ounces) and cook for 2-3 minutes until wilted. Remove bay leaves and discard.

Step 5: Stir in the juice and zest of 1 lemon. Taste and adjust seasoning as needed, adding more salt, pepper, or lemon juice to brighten the flavors.

Step 6: Ladle into bowls and finish with a drizzle of good olive oil and fresh herbs if desired. Serve hot with crusty bread for dipping.

Preparing the Perfect Base

For the most flavorful homemade lentil soup with spinach and lemon, don’t rush the initial vegetable sauté. This step builds the foundation of flavor that makes this soup memorable. The vegetables should become soft and just beginning to caramelize before adding the garlic and spices.

Adding the Lemon Correctly

The bright citrus note is what transforms this from ordinary lentil soup to something special. Always add lemon juice at the end of cooking to preserve its fresh flavor. If you add it too early, the acidity dulls and you lose that vibrant pop that makes this best lentil soup with spinach and lemon recipe shine.

Pro Tips for Success

Elevate your lentil soup with spinach and lemon with these expert techniques:

• Sort your lentils – Before cooking, spread lentils on a light-colored plate to spot and remove any small stones or debris
• Don’t skip the spice blooming – Briefly heating the spices in oil unlocks their aromatic compounds for deeper flavor
• Control the texture – For a thicker soup, use an immersion blender to partially puree, or remove a cup of soup, blend it, and return to the pot
• Rice hack – Add 1/4 cup rice with the lentils for extra body and creaminess
• Finish with quality – Use your best olive oil for the final drizzle; the fruity notes complement the lemon perfectly
• Season gradually – Add salt in stages rather than all at once for more balanced flavor throughout

Can I prepare this lentil soup ahead of time?

Absolutely! This soup actually improves with time as flavors meld. Make it up to 3 days ahead and refrigerate. Wait to add the spinach and lemon until reheating for the freshest flavor and brightest color.

What can I substitute for lentils?

If you’re out of lentils, split peas or small white beans make excellent substitutions. Beans will need pre-soaking and longer cooking time, while split peas cook in roughly the same time as lentils.

Top 4 FAQs About Lentil Soup with Spinach and Lemon

Is lentil soup with spinach and lemon kid-friendly?

Yes! Many children enjoy this soup because the lemon adds a pleasant brightness that appeals to young palates. For particularly selective eaters, you can blend the soup smooth and reduce the amount of spinach initially. The natural sweetness from carrots also helps make this soup kid-approved.

Can I make this soup in an Instant Pot or slow cooker?

Absolutely! For Instant Pot: Use sauté function for steps 1-2, then add remaining ingredients except spinach and lemon. Cook on high pressure for 15 minutes with natural release. Add spinach and lemon after pressure cooking. For slow cooker: Complete steps 1-2 in a skillet, transfer to slow cooker with remaining ingredients except spinach and lemon. Cook on low for 6-8 hours or high for 3-4 hours, adding spinach and lemon in the final 10 minutes.

How can I make this soup more filling for a main dish?

Transform this into a complete meal by adding one of these options: 1) Stir in cooked quinoa or brown rice during the last 5 minutes; 2) Add diced potato or sweet potato with the lentils; 3) Serve with a dollop of Greek yogurt (non-vegan option); 4) Top with toasted pumpkin seeds or croutons for extra texture and nutrients.

Does this soup taste good without lemon?

While the lemon is a signature ingredient that brightens the flavors substantially, you can substitute apple cider vinegar (use half the amount) or a splash of white wine for acidity if you don’t have lemons. However, you’ll miss the distinctive citrus notes that make this recipe special. The lemon zest particularly adds aromatic oils that transform the soup’s profile.

Protein-Packed: Brown 8 ounces of ground turkey or plant-based meat substitute with the vegetables at the beginning. For a non-vegan option, add shredded rotisserie chicken during the last 5 minutes.

Hearty Winter Version: Add 1 cup diced butternut squash or sweet potato with the lentils, and stir in 1/4 teaspoon cinnamon with the other spices for a warming effect.
