Ingredients

Here is the simple, wholesome list of pantry and refrigerator staples you’ll need to create this incredibly nourishing and flavorful Lentil Veggie Soup. Each ingredient plays a crucial role in building the layers of deep, savory flavor.

• 2 Tablespoons Olive Oil: The foundation for sautéing your vegetables, creating the initial layer of flavor. A good quality extra-virgin olive oil will impart a subtle, fruity note.
• 1 Large Yellow Onion, chopped: Provides a sweet and aromatic base that is essential for almost any great soup.
• 3 Medium Carrots, peeled and diced: Adds a natural sweetness, beautiful color, and a tender bite.
• 3 Celery Stalks, diced: Delivers a slightly salty, savory, and fresh vegetal flavor that perfectly balances the sweetness of the carrots.
• 4 Cloves Garlic, minced: A powerhouse of pungent, savory flavor that deepens and enhances all the other ingredients.
• 1 ½ cups Brown or Green Lentils, rinsed: The star of the show. These lentils hold their shape well during cooking, providing a wonderful texture and an earthy, protein-packed foundation.
• 8 cups Vegetable Broth: The liquid medium for our soup. A flavorful, low-sodium vegetable broth is recommended to control the saltiness of the final dish.
• 1 (28-ounce) can Diced Tomatoes, undrained: These add a bright acidity, a touch of sweetness, and a lovely texture that breaks up the earthiness of the lentils.
• 2 Medium Potatoes, peeled and diced: Makes the soup even heartier and more satisfying, adding a creamy texture as they cook down.
• 1 Teaspoon Dried Thyme: An essential herb that pairs beautifully with lentils, adding a classic, woodsy, and slightly floral aroma.
• 1 Teaspoon Ground Cumin: Lends a warm, earthy, and slightly smoky flavor that is characteristic of many classic lentil dishes.
• ½ Teaspoon Smoked Paprika: Adds a gentle, smoky depth that elevates the soup from good to great.
• 1 Bay Leaf: A subtle aromatic that infuses the broth with a complex, savory background note. Remember to remove it before serving!
• Salt and Freshly Ground Black Pepper, to taste: The fundamental seasonings that will bring all the flavors into focus.
• 4 cups Fresh Spinach or Kale, chopped: Wilted in at the end to add a vibrant green color, a host of nutrients, and a fresh, earthy taste.
• 2 Tablespoons Lemon Juice or Apple Cider Vinegar: The secret ingredient! A splash of acid at the end brightens up all the flavors and makes the soup taste incredibly fresh and vibrant.

Instructions

Follow these simple, step-by-step instructions to create a perfect pot of Lentil Veggie Soup. The process is straightforward and involves building layers of flavor from the very first step.

1. Build the Flavor Base: Place a large Dutch oven or heavy-bottomed pot over medium heat. Add the olive oil and let it shimmer. Add the chopped onion, diced carrots, and diced celery (this trio is known as a mirepoix). Sauté the vegetables for 8-10 minutes, stirring occasionally, until they have softened and the onion is translucent and fragrant. This step is crucial for developing a deep, sweet foundation for your soup.
2. Bloom the Aromatics: Add the minced garlic, dried thyme, ground cumin, and smoked paprika to the pot. Stir constantly for about 1 minute until the garlic and spices are very fragrant. This process, known as “blooming,” toasts the spices, releasing their essential oils and intensifying their flavor. Be careful not to let the garlic burn.
3. Combine the Main Ingredients: Pour in the vegetable broth, using a wooden spoon to scrape up any browned bits from the bottom of the pot (this is called deglazing and adds a ton of flavor). Add the rinsed lentils, the undrained can of diced tomatoes, the diced potatoes, and the bay leaf.
4. Simmer to Perfection: Stir everything together well and bring the soup to a boil. Once boiling, reduce the heat to low, cover the pot, and let it simmer for 40-50 minutes. The soup is ready when the lentils and potatoes are tender and cooked through. The cooking time can vary slightly depending on the age and type of your lentils.
5. Add the Greens: Once the lentils are tender, remove the pot from the heat. Fish out and discard the bay leaf. Stir in the chopped fresh spinach or kale. The residual heat from the soup will be enough to wilt the greens perfectly in just a couple of minutes.
6. The Finishing Touch: Stir in the fresh lemon juice or apple cider vinegar. This final splash of acid is a non-negotiable step; it awakens all the savory, earthy flavors and makes the soup taste bright and complete.
7. Season and Serve: Taste the soup and season generously with salt and freshly ground black pepper until the flavors are balanced to your liking. Ladle the hot soup into bowls and serve immediately with your favorite garnishes.

Additional Tips

Here are eight tips to help you customize, store, and perfect your Lentil Veggie Soup.

1. Choose Your Lentils Wisely: While the recipe calls for brown or green lentils because they hold their shape, you can use others. Red or yellow lentils will cook faster and break down more, resulting in a creamier, thicker, purée-like soup, which can also be delicious.
2. For a Creamier Texture: If you prefer a creamier soup without adding dairy, use an immersion blender to blend about one-third of the soup directly in the pot. This will thicken the broth while still leaving plenty of whole lentils and vegetables for texture.
3. Meal Prep and Storage Champion: This soup is fantastic for meal prep. It tastes even better the next day as the flavors continue to meld. Store it in an airtight container in the refrigerator for up to 5 days.
4. Freezer-Friendly Instructions: This soup freezes beautifully. Let it cool completely, then transfer it to freezer-safe containers or bags, leaving a little space at the top for expansion. It can be frozen for up to 3 months. Thaw it overnight in the refrigerator and reheat gently on the stove.
5. Clean Out the Crisper Drawer: This recipe is incredibly versatile. Feel free to add other vegetables you have on hand. Diced sweet potatoes, bell peppers, zucchini, mushrooms, or green beans are all excellent additions. Add quicker-cooking vegetables like zucchini in the last 15-20 minutes of simmering.
6. Boost the Umami: For an even deeper, more savory flavor, add a tablespoon of tomato paste along with the garlic and spices. For non-vegans, tossing in a Parmesan cheese rind while the soup simmers will impart an incredible, savory depth. Just remember to remove it with the bay leaf before serving.
7. Don’t Skip the Acid: It bears repeating: the final splash of lemon juice or vinegar is transformative. It cuts through the earthiness of the lentils and brightens every single flavor in the pot. If your soup tastes flat, it almost always needs more salt and a squeeze of acid.
8. Make it Fully Vegan: This recipe is naturally vegan-friendly. Simply ensure you use a certified vegan vegetable broth and opt for plant-based toppings like vegan sour cream, cashew cream, or a sprinkle of nutritional yeast for a “cheesy” flavor.

FAQ Section

Here are answers to some of the most frequently asked questions about making Lentil Veggie Soup.

1. Do I need to soak the lentils before cooking?
No, you do not need to soak brown or green lentils for this recipe. Unlike dried beans, lentils cook relatively quickly. Soaking them can actually make them too soft and cause them to fall apart during the simmering process. Simply give them a good rinse under cool water to remove any dust or debris before adding them to the pot.

2. Can I use different types of lentils in this soup?
Absolutely! As mentioned in the tips, you can substitute other lentils. Brown or green lentils are recommended for a soup with more texture. Red or yellow lentils will break down and create a much thicker, creamier consistency, similar to an Indian dal. The cooking time will also be shorter, around 20-25 minutes.

3. How long does this soup last in the refrigerator?
This soup stores very well. Once cooled, place it in an airtight container and it will keep in the refrigerator for up to 5 days. The flavor often deepens and improves by the second day. The soup will thicken as it sits, so you may need to add a splash of water or broth when reheating.

4. Is this Lentil Veggie Soup freezer-friendly?
Yes, this is an excellent recipe for freezing. Allow the soup to cool completely before portioning it into freezer-safe bags or containers. It can be stored in the freezer for up to 3 months. For best results, thaw it overnight in the refrigerator before reheating gently on the stovetop.

5. Can I make this soup in a slow cooker or an Instant Pot?
Yes, this soup is very adaptable.

• For a Slow Cooker: Sauté the onion, carrots, celery, garlic, and spices on the stovetop as directed for maximum flavor. Then, transfer them to the slow cooker and add all remaining ingredients except the spinach and lemon juice. Cook on low for 6-8 hours or on high for 3-4 hours. Stir in the spinach and lemon juice just before serving.
• For an Instant Pot: Use the “Sauté” function to cook the mirepoix, garlic, and spices. Add the remaining ingredients (except spinach and lemon juice). Secure the lid, set the valve to “Sealing,” and cook on high pressure for 15 minutes. Allow for a 10-minute natural pressure release before quick-releasing the rest. Stir in the spinach and lemon juice.

6. My soup is too thick (or too thin). How can I fix it?
This is an easy fix! If your soup is too thick, simply stir in a bit more vegetable broth or water until it reaches your desired consistency. If your soup is too thin, you can let it simmer uncovered for an extra 10-15 minutes to allow some of the liquid to evaporate and thicken it up. Alternatively, you can mash some of the potatoes and lentils against the side of the pot or use the immersion blender trick mentioned in the tips.

7. Is this recipe gluten-free?
Yes, as written, this recipe is naturally gluten-free. All the ingredients—vegetables, lentils, and spices—are gluten-free. Just be sure to check the label on your vegetable broth to ensure it is certified gluten-free, as some brands may contain hidden gluten.

8. Can I add meat to this soup?
Of course. While this soup is designed to be a hearty vegetarian meal, it is also a fantastic base for adding meat. For a non-vegetarian version, you could brown 1 pound of ground beef or Italian sausage with the onions at the beginning. Shredded cooked chicken or diced ham can also be stirred in during the last 10 minutes of simmering to heat through.
