Tuscan Tomato Lentil & Spinach Soup

Description

Tuscan Tomato Lentil & Spinach Soup is a hearty, comforting, and nutritious one-pot soup filled with tender lentils, rich tomatoes, fresh spinach, aromatic vegetables, garlic, and Italian herbs. It has the cozy character of a traditional Italian-inspired soup while remaining simple enough for a busy weeknight.

The lentils provide a satisfying texture and plant-based protein, while tomatoes create a rich and slightly tangy broth. Fresh spinach is stirred in near the end so it stays vibrant and tender. Garlic, onion, carrots, celery, oregano, thyme, and basil add layers of savory flavor.

This soup is especially delicious on chilly evenings, but it’s also a fantastic meal-prep recipe because the flavors become even better after resting overnight. Serve it with crusty bread, toasted sourdough, a simple green salad, or a sprinkle of Parmesan.

Ingredients

For the Soup

• 1½ cups dry brown or green lentils, rinsed
• 2 tablespoons olive oil
• 1 medium yellow onion, diced
• 2 medium carrots, diced
• 2 celery stalks, diced
• 4 cloves garlic, minced
• 1 can (28 ounces) crushed tomatoes
• 1 can (14.5 ounces) diced tomatoes
• 6 cups vegetable broth
• 2 cups fresh baby spinach
• 1 tablespoon tomato paste
• 1 teaspoon dried oregano
• 1 teaspoon dried basil
• ½ teaspoon dried thyme
• 1 bay leaf
• ½ teaspoon smoked paprika, optional
• ½ teaspoon black pepper
• ¾ teaspoon salt, or to taste
• 1 tablespoon fresh lemon juice or red wine vinegar

Optional Ingredients

• ½ teaspoon red pepper flakes
• ½ cup grated Parmesan
• 1 tablespoon chopped fresh parsley
• 1 tablespoon fresh basil
• 1 zucchini, diced
• ½ cup chopped mushrooms
• ½ cup cooked white beans

Instructions

Step 1: Rinse the Lentils

Place the lentils in a fine-mesh strainer.

Rinse thoroughly under cool running water.

Pick through them and remove any small stones or damaged lentils.

Unlike dried beans, lentils generally don’t require soaking.

Set them aside.

Step 2: Sauté the Aromatics

Heat olive oil in a large Dutch oven or heavy-bottomed soup pot over medium heat.

Add the diced onion, carrots, and celery.

Cook for approximately 6–8 minutes, stirring occasionally.

The vegetables should soften and become fragrant.

This first step builds the flavor foundation of the soup.

Step 3: Add Garlic

Add the minced garlic.

Cook for approximately 30–60 seconds, stirring continuously.

Don’t allow the garlic to brown too much.

You want it fragrant and lightly softened.

Step 4: Add Tomato Paste

Stir in the tomato paste.

Cook for approximately 1–2 minutes.

Allowing the tomato paste to cook briefly helps deepen its flavor and gives the finished soup a richer tomato character.

Step 5: Add Tomatoes and Lentils

Add the crushed tomatoes and diced tomatoes.

Stir in the rinsed lentils.

Then pour in the vegetable broth.

Stir everything together.

Step 6: Add the Seasonings

Add:

• Oregano
• Basil
• Thyme
• Bay leaf
• Black pepper
• Salt
• Smoked paprika, if using

If you enjoy a little heat, add red pepper flakes.

Stir well.

Step 7: Simmer the Soup

Bring the soup to a gentle boil.

Once boiling, reduce the heat to low.

Cover partially with a lid.

Simmer for approximately 30–40 minutes, stirring occasionally.

The lentils should become tender but not completely fall apart.

Cooking time can vary depending on the type and age of the lentils.

Step 8: Check the Consistency

When the lentils are tender, check the soup.

If it seems too thick, add additional vegetable broth or water.

If you prefer a thicker soup, continue simmering uncovered for several minutes.

For an especially creamy texture, use an immersion blender for just a few seconds.

Don’t completely puree the soup unless you want a smooth consistency.

A partially blended soup gives you the best of both textures.

Step 9: Add the Spinach

Turn the heat to low.

Add the fresh spinach.

Stir gently.

The spinach will wilt quickly, usually within 1–2 minutes.

Avoid cooking it for too long because you want it to remain fresh and vibrant.

Step 10: Add Fresh Acidity

Remove the bay leaf.

Add fresh lemon juice or red wine vinegar.

Start with a small amount, taste, and add more if needed.

This little touch of acidity is important because it brightens the rich tomato and lentil flavors.

Step 11: Taste and Adjust

Taste the soup.

Add more:

• Salt
• Black pepper
• Lemon juice
• Red pepper flakes
• Italian herbs

as needed.

If the tomatoes taste particularly acidic, a very small pinch of sugar can help balance the flavor.

Step 12: Serve

Ladle the soup into bowls.

Top with fresh parsley or basil.

Add grated Parmesan if desired.

Finish with a small drizzle of extra-virgin olive oil.

Serve hot with crusty bread.

Simply add a splash of broth or water before reheating.

Storage
