Equipment You’ll Need

• Large pot or Dutch oven
• Chef’s knife
• Cutting board
• Wooden spoon or spatula
• Ladle
• Measuring cups and spoons

Ingredients

• 2 tablespoons olive oil
• 1 large yellow onion, chopped
• 2 large carrots, peeled and diced
• 2 celery stalks, diced
• 4 cloves garlic, minced
• 1 teaspoon dried thyme
• 1/2 teaspoon smoked paprika
• 1/4 teaspoon red pepper flakes (optional, for heat)
• 1.5 cups brown or green lentils, rinsed and picked over
• 1 (28-ounce) can diced tomatoes, undrained
• 8 cups vegetable broth, low-sodium
• 2 bay leaves
• 1 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon black pepper, freshly ground
• 5 ounces fresh spinach
• 2 tablespoons fresh lemon juice
• Fresh parsley, chopped, for garnish

Instructions

1. Heat the olive oil in a large pot or Dutch oven over medium heat. Add the chopped onion, carrots, and celery (this is your mirepoix). Sauté for 8-10 minutes, stirring occasionally, until the vegetables have softened.
2. Add the minced garlic, dried thyme, smoked paprika, and optional red pepper flakes to the pot. Cook for another minute until fragrant, stirring constantly to prevent the garlic from burning.
3. Pour in the rinsed lentils, the can of diced tomatoes (with their juices), the vegetable broth, and the bay leaves. Stir everything together to combine.
4. Increase the heat to high and bring the soup to a boil. Once boiling, reduce the heat to low, cover the pot, and let it simmer for 35-45 minutes, or until the lentils are tender but not mushy.
5. Once the lentils are cooked, remove the pot from the heat. Fish out and discard the bay leaves.
6. Stir in the fresh spinach a handful at a time. The residual heat from the soup will wilt the spinach within a minute or two.
7. Stir in the fresh lemon juice, 1 teaspoon of salt, and 1/2 teaspoon of black pepper. Taste the soup and adjust seasoning as needed. You may need more salt depending on the saltiness of your broth.
8. Ladle the soup into bowls, garnish with fresh parsley, and serve hot.

Expert Cooking Tips

• Rinse your lentils thoroughly under cold water before cooking to remove any dust or debris. It’s also wise to quickly pick through them to ensure no small stones are present.
• Don’t add the salt or acidic ingredients (lemon juice, tomatoes) until the lentils are tender. Adding them too early can sometimes prevent the lentils from softening properly.
• For a thicker, creamier consistency without adding dairy, you can use an immersion blender to partially blend the soup directly in the pot. Just a few pulses will do the trick.

Substitutions and Variations

You can use red lentils, but they cook much faster (about 20-25 minutes) and will result in a softer, more puréed texture. Feel free to add other vegetables like diced potatoes, sweet potatoes, or butternut squash along with the mirepoix. Kale can be substituted for spinach, but add it a few minutes earlier as it takes longer to soften. A splash of balsamic vinegar can be used instead of lemon juice for a different kind of acidic finish.

Common Mistakes to Avoid

A common mistake is under-seasoning. Lentils and vegetable broth can be bland on their own, so don’t be shy with the aromatics, salt, and pepper. Tasting and adjusting the seasoning at the end is crucial. Another issue is overcooking the lentils until they turn to complete mush. Check for tenderness around the 35-minute mark and cook only until they are soft but still hold their shape.

Serving Suggestions

This hearty soup is a meal in itself, but it pairs wonderfully with a slice of crusty bread or a warm whole-wheat pita for dipping. A simple side salad with a vinaigrette dressing provides a fresh, crisp contrast. For a richer dish, you can add a dollop of plain yogurt or a vegan sour cream on top before serving.

Storage and Reheating Tips

Allow the soup to cool completely before storing. It can be refrigerated in an airtight container for up to 5 days. The soup will thicken considerably as it cools; simply add a splash of water or vegetable broth when reheating on the stovetop or in the microwave. For longer storage, freeze the soup in freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator before reheating.

Frequently Asked Questions

Is this soup gluten-free?

Yes, all the ingredients in this recipe are naturally gluten-free. Just be sure to check that your vegetable broth is certified gluten-free if you have a severe intolerance.

Can I make this in a slow cooker?

Absolutely. Sauté the mirepoix and aromatics on the stovetop first, then transfer them to the slow cooker. Add the remaining ingredients (except spinach and lemon juice) and cook on low for 6-8 hours or on high for 3-4 hours. Stir in the spinach and lemon juice just before serving.

Why are my lentils still hard after cooking for an hour?

This can happen if your lentils are old. Lentils, like all dried goods, have a shelf life and can become tougher to cook as they age. It can also be caused by adding salt or acidic ingredients too early in the cooking process.
