This vegan lentil cabbage soup is a breeze to prepare in a pressure cooker or on the stovetop. It's lightly smoky and spicy and includes nutritious lentils, tomatoes, onion, carrot, and perfectly tender (but not too soft) cabbage. This is a healthy and flavorful cabbage soup you'll crave year-round! Gluten-free.
Why We Love This Recipe
The pressure cooker has a way of bringing out the best in vegetable soups. The veggies magically maintain more of their color and are cooked perfectly, without becoming too soft or muddled. This peanut curry lentil soup and classic Instant Pot vegetable soup are great examples.

If you have an Instant Pot, it's definitely my preferred way to cook this soup. I've also included stovetop instructions for you, just in case.
This cabbage soup recipe makes a large batch, almost 3 quarts, but because it's so light we always go back for seconds... or thirds! In other words, it is a lot of soup but it disappears quickly.
And the flavor only gets better as it sits. You'll love having leftover cabbage soup to look forward to on chilly (and tired) weeknights. Lentils give the soup body and make it more satisfying than plain cabbage soup.
Pair lentil cabbage soup with a slice of buttery Southern-style vegan cornbread or this easy oil-free cornbread. And if you have family members who appreciate meatier vegan dishes (like my hubby), see the Variations section below for ideas to add more protein.
Ingredient Notes
- Cabbage - I used 1 small/medium head of green cabbage; this variety is easy to find in most grocery stores. Incorporate red cabbage, if you like.
- Lentils - Choose green or brown lentils for this soup. Their cook time aligns well with the cabbage and other vegetables.
- Canned Diced Tomatoes - I prefer fire-roasted tomatoes and usually have a can or two in the pantry for recipes like this or our favorite lentil chili. If you don't have fire-roasted, regular is fine, too.
- Spices - We like a bit of smoke and spice in our cabbage soup so I included smoked paprika, red pepper flakes, and cayenne. Feel free to omit or experiment with the amounts. Regular sweet paprika is also good if you don't have smoked. If you're not sure how spicy you want the soup to be, you can always add sriracha, hot sauce, or cayenne after cooking.
- Bouillon - I always keep a batch of this homemade vegan "chicken" broth powder in the fridge because it's SO GOOD, not to mention healthier and cheaper than most products. Give that recipe a try, or use an equal amount of your favorite vegan bouillon. If it's in a cube form, dissolve it in 1 cup of the water before adding to the pot.
Instant Pot Instructions
- Turn on the Instant Pot sauté function, and add the oil. Cook the onion for 2 to 3 minutes, stirring frequently (if not using oil, add a splash of water as needed).
- Add the carrots and garlic, and cook for about 30 seconds, stirring frequently. Add the smoked paprika, red pepper flakes, and cayenne, and stir. Press cancel to turn off the sauté function.
- Add the bouillon powder, tomatoes (with the juice), water, lentils, cabbage, salt and pepper. Using a large slotted spoon stir very well, making sure all of the ingredients are thoroughly combined. Also, make sure everything is below the IP's max fill line.
- Secure the Instant Pot lid and set to sealing. Cook on high pressure for 10 minutes. The Instant Pot will take almost 20 minutes to come to pressure, then the 10 minute timer will begin. When the Instant Pot beeps and the cook time is complete, carefully press the release valve. It will take 10 to 15 minutes for the pressure to release.
- Carefully remove the Instant Pot lid, and stir in the soy sauce or tamari, liquid smoke, vinegar, and vegan butter, if using.
- Let the soup cool for a few minutes. Taste and adjust seasonings as desired.

Stovetop Instructions

- Cover and bring to a boil. Reduce heat to medium-low and simmer for about 30 minutes or until the lentils are tender.
- Add the tamari, vinegar, liquid smoke, and vegan butter, if using.
- Let cool for a few minutes, then taste and adjust seasonings.

Variations
- Extra Spicy - as written, the spice level of this soup is mild to moderate and easily adjusted with more cayenne and red pepper flakes. Or stir in a few dashes of your favorite hot sauce before serving, and garnish with diced, fresh jalapeno.
- Meaty - Beef and cabbage are a classic combination, so you may enjoy store-bought vegan beefy crumbles, Beyond Meat, or Impossible burger in the soup. I recommend sautéing them separately while the soup is cooking. Stir it into the pot at the end of cooking, or add to individual servings. This is also a great way to accommodate different family members' preferences.
- Soy Curls or Tofu - If you like the idea of more meatiness but don't consume processed vegan meats, add sautéed soy curls, tofu or tempeh to your bowl. And this Vegan Taco Meat (made with ground soy curls) is a must!
- Oil-Free - you may omit the oil and sauté the veggies in water or broth, or simply skip the sautéing altogether. I've also tested this recipe without the initial sauté (just dump everything in, and pressure cook as directed), and it's still great.
Cabbage Soup FAQs
Sautéing the onion, garlic, and spices in oil for a few minutes slightly enhances the flavor, but I've also made this soup using the "dump-and-start" method, and it's still great. So it's up to you!
Kept in an airtight container in the refrigerator, cabbage soup is good for up to 5 days.
Absolutely. First, cool the soup completely. Place in a freezer-safe container, leaving at least an inch of space at the top for the liquid to expand. Freeze up to 2 months (maybe longer). Thaw overnight in the refrigerator.
Two tablespoons of vegan butter added after cooking creates a slightly richer and creamier broth, but this ingredient is optional. You can always give the soup a taste first, then decide whether to add the butter.

- 1 (28 oz) can fire-roasted diced tomatoes
- 4 cups water
- ¾ cup dry green lentils, rinsed

- 1 teaspoon fine sea salt
- ½ to 1 teaspoon freshly cracked black pepper

Instructions
Instant Pot Instructions:
- Turn on the Instant Pot sauté function, and add the oil. Cook the onion for 2 to 3 minutes, stirring frequently (if not using oil, add a splash of water as needed).
- Add the carrots and garlic, and cook for about 30 seconds, stirring frequently so the garlic doesn't burn. Add the smoked paprika, red pepper flakes, and cayenne, and stir. Press cancel to turn off the sauté function.
- Add the bouillon powder, tomatoes (with the juice), water, lentils, cabbage, salt and pepper. Stir very well, making sure all of the ingredients are thoroughly combined. Use the spoon to lightly press the cabbage into the liquids, making sure everything is below the Instant Pot's max fill line.
- Secure the Instant Pot lid and set to sealing. Cook on high pressure for 10 minutes. The Instant Pot will take almost 20 minutes to come to pressure, then the 10 minute timer will begin. When the Instant Pot beeps and the cook time is complete, carefully flip the valve to manually release the pressure (this is sometimes called "quick release"). Because of the large volume of liquid this may take about 10 minutes.
- Once the pressure button has dropped, carefully remove the Instant Pot lid. Stir in the soy sauce, liquid smoke, vinegar, and vegan butter, if using.
- Let the soup cool for a few minutes. Taste and adjust seasonings as desired.

I followed this recipe (almost) exactly. I only put in a pinch of red pepper flakes—unfortunately, we don’t like “hot,” and even a pinch was too spicy for us. Next time, I won’t use any. I had Napa cabbage on hand from the Farmers Market and it worked nicely. Soup was hearty and healthy. Will definitely make again! Oh! And making it in my InstantPot was so much fun! Easy peasy, and QUICK!
Monika Mroczkowski
I made this lentil cabbage soup recently and we all loved it. I love cabbage. Period. But paired with all the other ingredients, it made it that much better. Adding lentils was such a great idea. I doubled the recipe because we eat a lot of soup, especially during the cooler months. Thank you for sharing, Lori!

Thank you for this, Lori! Cabbage soup is typically pretty decent, but your additions - lentils, as well as the "after cooking" ingredients - take it up 10 notches!
