Why you’ll love this vegan red lentil soup
Here’s why you need to whip up a batch of this soup:

The end of February is usually the time of year when New Englanders begin to wonder if living in the northeast is such an excellent idea after all, the snow is still lingering and the nights are cold. Enough already, where is spring? Nothing better than a red lentil soup to brighten the day and warm the frozen limbs.
When I make this soup, I usually make a whole bunch and store leftovers in the freezer. This soup freezes so well, and when I don’t have time to cook, I take a bag out of the freezer and have a wonderful hardy meal in no time. Best of all, this soup puts a spring in your step and gives extra energy for the day. Yes, having a few portions of this red lentil soup in your freezer makes life easier.
Ingredients and substitution notes
Here’s what to gather to make your vegan red lentil soup:
- Olive oil: Choose a good quality extra virgin olive oil for better flavor. You can also use avocado oil.
- Onion: Use yellow or white onion.
- Garlic clove: I recommend fresh and not powdered in this recipe.
- Leek: Clean the leek thoroughly, as it often traps dirt between its layers.
- Thyme: Fresh thyme sprigs or dried thyme leaves can be used.
- Cayenne: Cayenne adds flavor; you could leave this out if you don’t like it!
- Carrot: I love the earthiness of carrots. Parsnip is a great alternative.
- Celery stalk: Finely chop celery stalks to add a savory note and texture to the soup.
- Vegetable broth: I prefer a low-sodium vegetable broth to control the saltiness of the soup.
- Whole red lentils: Rinse lentils thoroughly to get rid of any debris before adding to the soup.
- Can crushed tomatoes: Use high-quality canned crushed tomatoes without added seasoning for a rich tomato base.
- Potato: It adds a nice texture and thickness to the soup.
- Better-Than-Bouillon (vegetable base) + salt: Better-Than-Bouillon provides concentrated vegetable flavor; adjust salt accordingly.
- Bay leaf: Adding a bay leaf adds next-level flavor; remove it before serving.
Vegan Red Lentil Soup recipe variations and add-ins
Here are few ways you can change up this base recipe:
- Mediterranean style: Add chopped spinach or kale towards the end of cooking for added nutrition and vibrant color. Finish with a squeeze of lemon juice for brightness.
- Smoky: Add a touch of smoked paprika or chipotle powder for a smoky flavor profile. You could add diced smoked tofu extra texture and protein. Serve with a wedge of lime.
- Italian-inspired: Stir in chopped fresh basil, oregano, and a vegan Parmesan rind while simmering.
- Chunky vegetable: Increase the quantity of carrots, celery, and potatoes for a heartier, chunkier soup. Add diced zucchini, bell peppers, or butternut squash for other veggies.
- Coconut: Replace some vegetable broth with coconut milk for a creamy and indulgent soup. Garnish with chopped fresh cilantro.
Top tips for making vegan red lentil soup
This is honestly such a simple vegan red lentil soup. Here’s how to get the best out of this recipe:
- Thoroughly rinse lentils: Before using red lentils in your soup, rinse them under cold water to remove any debris. Lentils (like rice) can hold a lot of impurities.
- Don’t overcook vegetables: Be mindful not to overcook the vegetables, especially the potatoes. They should be tender but still have a slight bite for texture.
- Adjust consistency: Red lentil soup thickens as it cooks and sits. If it becomes too thick, add more vegetable broth or water.
- Let flavors develop: Allow the soup to simmer gently to allow the flavors to meld together. This also gives the lentils and vegetables time to cook thoroughly and become tender.
Make ahead instructions and storage
Can you make this vegan red lentil soup ahead of time?
Make-ahead:
Fully cook the soup and cool it completely at room temperature before transferring it to airtight containers. This prevents condensation and helps maintain the soup’s freshness.
How to Refrigerate or Freeze Vegan Red Lentil Soup:
Once cooled, refrigerate the soup in airtight containers for up to 3-4 days. Alternatively, if you plan to store it for longer, transfer it to freezer-safe containers and freeze for up to 3 months.
To Reheat and Serve:
When ready to serve refrigerated soup, simply reheat it gently in a pot on the stove over medium heat. Stir occasionally until heated through.
For frozen soup, thaw it overnight in the refrigerator before reheating. Once thawed, reheat on the stove over low to medium heat, stirring occasionally until thoroughly heated.
As the soup reheats, you may need to adjust the consistency by adding a splash of water or broth if it has thickened too much.
Storage
Use airtight containers or resealable freezer bags to store the soup, ensuring they are tightly sealed to prevent freezer burn or absorption of odors.
Consider portioning the soup into smaller containers before freezing. This allows you to thaw only the amount you need without having to defrost the entire batch.
Never place hot soup directly in the refrigerator or freezer. Allow it to cool to room temperature first to avoid temperature fluctuations that could affect food safety.

- Avocado toast: Top slices of toasted bread with mashed avocado, a sprinkle of salt, red pepper flakes, and a squeeze of lemon juice.
- Herbs and garnishes: Sprinkle freshly chopped herbs such as parsley, cilantro, or chives over the soup.
- Toasted nuts or seeds: Garnish your soup with a handful of toasted nuts or seeds such as pumpkin seeds, sunflower seeds, or slivered almonds for added crunch and texture.
