Ingredients You’ll Need for Classic Lentil Soup

Creating a delicious bowl of Classic Lentil Soup is as easy as gathering a few simple ingredients. Here’s what you need:

Essentials

• 2 tablespoons olive oil: For sautéing and adding depth of flavor.
• 1 yellow onion (diced): The aromatic base that starts everything off.
• 3 carrots (sliced): Sweetness and vibrant color provide a delightful addition.
• 2 stalks celery (sliced): Adds texture and a refreshing crunch.
• 1 tablespoon tomato paste: A concentrated flavor booster essential for depth.
• 3 cloves garlic (minced): Adds a fragrant touch to the soup.
• 1 teaspoon Italian seasoning: A warm blend of herbs that elevates the overall flavor.
• 1 teaspoon paprika: For a hint of smokiness and mild heat.
• 1/2 teaspoon cumin: Introduces an earthy flavor to the profile.
• 2 bay leaves: Infuses aroma as the soup simmers.
• Black pepper (to taste): Enhances the soup’s natural flavors.
• 2 cups dry green lentils (sorted and rinsed): The star of the dish, providing protein and texture.
• 1 (14.5-ounce) can crushed tomatoes: A juicy burst of freshness.
• 4 cups vegetable broth: The liquid base that brings everything together.
• 3-4 cups water: Adjust for desired thickness.
• 1 tablespoon fresh lemon juice: A zesty finish that brightens all the flavors.
• 2 tablespoons chopped parsley (for garnish): A vibrant touch to make the dish visually appealing.

Optional Add-Ons

While this recipe is already delicious on its own, you can swap or add a few optional ingredients to tailor it to your tastes:

• Leafy greens: Consider adding kale or spinach in the last few minutes of cooking for an added nutritional boost.
• Potatoes: Diced potatoes can add heartiness and creaminess to the soup.
• Corn: Frozen or canned corn can introduce sweetness and fun texture.

Substitutions and Shortcuts

If you’re in a pinch or don’t have certain ingredients on hand, here are some easy substitutions:

• Instead of fresh garlic, you can use garlic powder (adjust the amount based on preference).
• If you don’t have bay leaves, consider substituting with fresh thyme or oregano for a different aromatic touch.
• Don’t stress if you can’t find green lentils—brown lentils or even red lentils work well, just adjust the cooking time accordingly as red lentils cook faster.

How to Make Classic Lentil Soup Step-by-Step

Let’s dive into the process of creating this hearty Classic Lentil Soup. Follow these detailed steps to whip up a pot that is sure to fill your home with warmth and love.

Step 1: Sauté the Aromatics

Begin your culinary journey by warming 2 tablespoons of olive oil in a Dutch oven or a large pot over medium heat. As the oil heats, it will set the foundation for your aromatic base.

Once the oil shimmers, add in the diced yellow onion. Sauté for 2 to 3 minutes until it becomes translucent and fragrant. Next, toss in the sliced carrots and sliced celery, continuing to sauté for about 1 minute. Now it’s time to introduce the tomato paste. Stir it through the sautéed vegetables, ensuring everything is evenly coated. This step only takes about 2 to 3 minutes, but it’s crucial for layering the flavors.

Step 2: Add the Spices

Now comes the part that truly elevates your soup. Add 3 minced cloves of garlic, along with the Italian seasoning, paprika, cumin, bay leaves, and a sprinkle of black pepper to the pot. Stir well for about 1 minute—this toasting of the spices will enhance their flavors, making your soup aromatic and rich.

Step 3: Simmer the Soup

With the spices beautifully mingled with the vegetables, it’s time to introduce the 2 cups of dry green lentils. Pour in the crushed tomatoes, 4 cups of vegetable broth, and 3 cups (700 ml) of water. Give everything a gentle stir to combine.

Bring your pot to a boil over high heat, then reduce the heat to medium. Allow the soup to simmer for about 20 to 30 minutes, stirring occasionally, until the lentils are tender. Keep an eye on the consistency—if it becomes thicker than you’d like, feel free to add the additional 1 cup of water as necessary. The beauty of this dish is how adaptable it is!

Step 4: Finishing Touches

Once your lentils are cooked to perfection, remove the bay leaves—they’ve done their job. Stir in 1 tablespoon of fresh lemon juice, which brings a bright, zesty flavor to the soup. Taste your creation and adjust the seasoning with salt and pepper as needed.

Step 5: Serve

Your Classic Lentil Soup is ready to be served! Ladle it into bowls and sprinkle with 2 tablespoons of chopped parsley for a fresh, vibrant touch. For a truly cozy experience, consider pairing it with freshly baked bread or crisp crackers.

You can store any leftovers in the refrigerator for up to 5 days or freeze them for up to 2 months—if it lasts that long!

Common Mistakes to Avoid When Making Classic Lentil Soup

Even with such a straightforward recipe, here are a few common pitfalls to avoid to ensure your Classic Lentil Soup turns out beautifully every time.

Using the Wrong Lentils

Not all lentils are created equal. Green lentils hold their shape well and offer a beautiful texture, making them perfect for soups. Using split red lentils, on the other hand, will give you a mushier consistency. While it’s not disastrous, you’ll lose that beautiful hearty quality. Stick with green or brown lentils for this recipe.

Adding Salt Too Early

Adding salt too early can affect the cooking of your lentils, making them tough. Wait until the end to season your soup—this way, you’ll have a better gauge of the flavors and improve the overall taste.

Overcooking the Soup

With lentils, timing is everything. Overcooking can lead to a mushy disaster rather than the tender bite that you desire. Keep an eye on your lentils and stop cooking as soon as they’re just tender.

Skipping the Lemon Juice

Don’t underestimate the power of that 1 tablespoon of fresh lemon juice. It brightens the flavors immensely and can turn an okay soup into a fantastic one. Don’t leave it out; your final dish deserves it.

Serving Suggestions for Classic Lentil Soup

Classic Lentil Soup is delightful on its own, but if you want to make your meal even more enjoyable, here are some serving suggestions.

Fresh Bread

Nothing complements a hearty soup better than a slice of warm, crusty bread. Whether it’s a homemade sourdough or a store-bought baguette, dunking bread into your Classic Lentil Soup not only makes for a satisfying experience but also helps soak in all those wonderful flavors.

A Side Salad

Pairing your soup with a light, crisp side salad adds texture and freshness. Consider a simple mixed greens salad with a vinaigrette to balance the hearty nature of the soup. The brightness of the vegetables will highlight the earthy flavors of the lentils beautifully.

Cheese Topping

If you’re a cheese lover, consider topping your soup with some grated Parmesan or crumbled feta just before serving. A little sprinkle can enhance the taste and adds a lovely saltiness to the overall dish.

Rice or Quinoa

For a heartier meal, you can serve your Classic Lentil Soup over a bed of cooked rice or quinoa. This provided base not only adds extra substance but also offers contrasting textures, enhancing your dining experience.

Pro-Level Tips for When You’re Ready

Once you feel comfortable with the basics, here are some pro-level tips to elevate your Classic Lentil Soup game even further.

Experiment with Spices

While the recipe calls for Italian seasoning, there’s a world of spices at your fingertips! Consider adding a pinch of red pepper flakes for heat or even a dash of curry powder for an exciting twist. Don’t shy away from making this recipe your own with different flavor profiles.

Incorporate Seasonal Vegetables

What’s in season? Make the most of it! In winter, try adding diced sweet potatoes or winter squash. In spring, don’t hesitate to throw in some peas or asparagus for freshness. This flexibility will keep your lentil soup exciting year-round.

Mindful Cooking

Make it a moment. While lentil soup is often thought of as a quick weeknight dinner, I love to take my time. Chop the vegetables mindfully, enjoy the aromas, and let the soup simmer slowly. Cooking can be therapeutic, so embrace the process.

Meal Prep Like a Pro

Lentil soup is a fantastic recipe for meal prepping. Consider making a double batch and freezing individual portions. This way, you’ll always have a comforting meal at the ready. Just reheat when you need a cozy night in.
