Step‑by‑Step Instructions for Classic Lentil Soup
Step 1: Rinse the Lentils
Begin by rinsing 1 cup of lentils under cold running water in a fine-mesh strainer. This helps to remove any dust or debris, ensuring your Classic Lentil Soup starts with clean, fresh ingredients. Once rinsed, set the lentils aside to drain well while you prepare the vegetables.
Step 2: Sauté the Aromatics
In a large pot, heat 2 tablespoons of olive oil over medium heat. Add 1 chopped onion and sauté for 4-5 minutes until the onions turn golden and translucent. The aroma will fill your kitchen, setting a warm tone for your Classic Lentil Soup. Once the onions are softened, it’s time to add the remaining vegetables.
Step 3: Add Vegetables & Garlic
Introduce 2 diced carrots, 2 diced celery stalks, and 3 minced garlic cloves to the pot. Sauté these for another 3-4 minutes until they begin to soften and become fragrant, stirring occasionally. The colorful mix will enhance the flavor and texture of your Classic Lentil Soup, making it hearty and inviting.
Step 4: Season the Mixture
Stir in 1 teaspoon of cumin, along with salt and pepper to taste. Mix well, allowing the spices to toast slightly in the pan for about 1 minute. This step will deepen the flavors of your Classic Lentil Soup and create a lovely aromatic base for the lentils and broth.
Step 5: Combine the Lentils and Tomatoes
Now, add in the rinsed lentils and one 14.5-ounce can of diced tomatoes (with their juice) to the pot. Stir everything together, ensuring that the lentils are well-coated with the seasoned mixture. This combination is where the essence of your Classic Lentil Soup truly begins to take shape.
Step 6: Add the Broth and Bay Leaf
Pour in 6 cups of vegetable broth and toss in 1 bay leaf for added flavor. Increase the heat to bring the mixture to a boil, then reduce the heat to low. This helps the flavors meld beautifully as your Classic Lentil Soup simmers gently, creating a comforting depth.
Step 7: Simmer the Soup
Allow the soup to simmer uncovered for 20-25 minutes, stirring occasionally until the lentils are tender. You’ll know it’s ready when they are soft but not mushy. The soup will thicken slightly, giving you a rich and hearty Classic Lentil Soup that’s perfect for chilly evenings.
Step 8: Final Adjustments and Serve
After simmering, remove the bay leaf and taste the soup, adjusting seasoning with more salt and pepper if desired. Garnish your Classic Lentil Soup with freshly chopped parsley for a splash of color and freshness. Now, it’s ready to warm your heart and nourish your body!

Make Ahead Options
These Classic Lentil Soup make-ahead options are perfect for busy home cooks looking to save time during the week! You can chop the vegetables (onion, carrots, celery, garlic) and store them in an airtight container in the refrigerator up to 3 days in advance. Additionally, rinse and pre-measure the lentils for even quicker preparation. When you’re ready to enjoy the soup, simply sauté the prepped vegetables, add the lentils and remaining ingredients, and simmer for about 20-25 minutes. This allows you to savor that home-cooked comfort with minimal effort, ensuring your Classic Lentil Soup remains just as delicious and nourishing as if made fresh on the spot!

Classic Lentil Soup Recipe FAQs
What type of lentils should I use for Classic Lentil Soup?
Absolutely! I recommend using green or brown lentils as they hold their shape well during cooking and provide a nice texture to the soup. Red lentils, on the other hand, will break down more and create a creamier consistency, which is lovely but lends a different quality to the dish.
How do I store leftover Classic Lentil Soup?
Very simply! After your delicious soup has cooled, pour it into an airtight container. It will stay fresh in the refrigerator for up to 5 days. For optimal flavor and safety, be sure to seal the container tightly.
Can I freeze Classic Lentil Soup?
Absolutely! To freeze your Classic Lentil Soup, allow it to cool completely after cooking. Then, ladle it into freezer-safe containers or zip-top bags—just remember to leave some space at the top for expansion as it freezes. Your soup can be enjoyed for up to 3 months. When you’re ready to enjoy it again, thaw in the refrigerator overnight and gently reheat on the stove, adding a splash of broth if it’s too thick!
What should I do if my soup is too thick after cooking?
No worries! If your Classic Lentil Soup turns out thicker than you’d like, simply add a little vegetable broth or water while stirring over low heat until you’ve reached your desired consistency. This way, you’ll retain the delicious flavors without compromising the texture.
Are there any dietary considerations for Classic Lentil Soup?
Definitely! This soup is naturally vegetarian and can easily be made vegan by using vegetable broth. Always check the labels for any canned ingredients like diced tomatoes, ensuring they’re free from any allergens you or your guests might have. If you have pets, it’s best to avoid feeding them soup seasoned with onions and garlic, as these can be harmful to them.
