Ingredients List

Main Ingredients

• 1 cup lentils (preferably green or brown)
• 1 medium onion, diced
• 2 cloves garlic, minced
• 2 medium carrots, sliced
• 2 celery stalks, sliced
• 1 can (14.5 oz) diced tomatoes (no salt added for a healthier option)
• 4 cups vegetable broth (low-sodium if preferred)
• 1 teaspoon dried thyme
• 1 teaspoon cumin
• Salt and pepper to taste
• 2 tablespoons olive oil
• Optional: Fresh spinach or kale for added nutrients
• Optional: A squeeze of lemon juice for an extra zest

Timing

Preparation for this dish takes about 10 minutes, cooking takes approximately 30 minutes, and the total time clocking in around 40 minutes—that’s 20% less time than the average soup recipe, allowing you to satisfy that craving for a warm, comforting dish in no time!

Step-by-Step Instructions

Step 1: Prepare the Ingredients

Begin by rinsing your lentils under cold water. Dice the onion, slice the carrots and celery, and mince the garlic. Having your ingredients prepped will streamline the cooking process, ensuring a smooth workflow.

Step 2: Sauté the Aromatics

In a large pot, heat the olive oil over medium heat. Add the diced onion, garlic, carrots, and celery. Sauté until the onions are translucent and vegetables are tender, about 5-7 minutes. This step builds the flavor foundation of your Hearty Vegetarian Lentil Soup.

Step 3: Add the Lentils and Spices

Stir in the rinsed lentils, thyme, cumin, salt, and pepper. Tossing in these aromatic spices at this stage helps infuse their flavors into the lentils as they cook.

Step 4: Incorporate Broth and Tomatoes

Pour in the vegetable broth and mix in the diced tomatoes. Bring the mixture to a gentle boil, then reduce the heat, cover, and simmer for 30 minutes or until the lentils are tender.

Step 5: Adjust Consistency

Check the soup midway—if it’s becoming too thick, feel free to add more broth or water. Soup is all about personal preference, and you want it to have a pleasing consistency.

Step 6: Add Greens (Optional)

If you’re adding spinach or kale, stir it in during the last 5 minutes of cooking. This will retain their vibrant color and nutritional benefits.

Step 7: Season and Serve

Taste test your soup and adjust seasoning if necessary. Once it’s to your liking, serve hot, and if desired, squeeze a fresh lemon over the top for an extra kick!

Storing Tips for the Recipe

Refrigerate any leftovers in an airtight container for up to 5 days. For longer storage, consider freezing portions for up to 3 months. When reheating, add a splash of water or broth to prevent it from becoming too thick.
