Healthy, hearty, and packed with smoky flavor...this vegetarian split pea soup is pure comfort in a bowl!
Do you have a go-to dish that you like to make when you have no idea what to make for dinner? I do! It's split pea soup. I make this stuff all year round (even during the hottest days of summer) and I love it.
Split pea soup is healthy, comforting, and so easy to make. In fact, I have about a million and one versions that I make, and I never actually follow a recipe.
I had a hard time picking a version for this post, but I decided to go with a vegan version of what I consider classic split pea soup — the smoky stuff that's normally made with ham.
Vegetarian Split Pea Soup Ingredients
Obviously there's no ham in here. Instead I seasoned it with a touch of liquid smoke, which is pretty much magic in a bottle when it comes to making meatless things taste smoky, as well as some cumin.
What is liquid smoke? Someone always asks this. Liquid smoke is a seasoning that's made by burning wood and condensing the smoke. So liquid smoke is actually smoke, in liquid form! Most supermarkets carry it near the barbecue sauces. You can also buy it online.
In addition to the seasonings you'll need some onions, carrots, celery and garlic, as well as vegetable broth, red wine vinegar, and, of course, split peas. The awesome thing about this soup is that it's easy to keep all of the ingredients on hand, so you can make it any time!
How to Make Split Pea Soup
First you'll need to sweat your veggies. Heat some oil in a large pot and add your onion, carrots and celery. You'll need to cook them for a few minutes before adding everything else, to start softening them up.
Once the veggies are soft, add some garlic and your cumin. Toasting the cumin first brings out the flavor.
Tip: I usually use ground cumin for this, because I always have it around, but if you keep whole cumin seeds on hand, throw in a half teaspoon or so. They'll really add some awesome flavor!
The garlic should become really fragrant after about a minute. Now it's time to add the broth and peas.
Give everything a good stir, crank up the heat and bring the broth to a simmer.
The tough part about cooking split pea soup is the wait. Split peas can take an hour or more to soften up completely. Be patient! Or don't, and scroll down for the Instant Pot instructions!
You may find that the broth dries up while your soup cooks. Keep a cup of hot water near the stove and add some whenever this happens.
Instant Pot Split Pea Soup
Don't have time to let your soup simmer for an hour or more? Make it in the Instant Pot!
Simply cook your carrots, celery and onion using the "sauté" function. Add your garlic and spices during the last minute, just like you'd do on the stove.
Hit the "cancel" button, then stir in your broth and split peas. Place the lid on your Instant Pot, set your valve to "sealing," and set your soup to pressure cook ("manual" button on older models) on high pressure for 15 minutes. When the time is up you can move the valve to "venting" and let the pressure release before opening the lid.
Season the Soup
Add the liquid smoke and a splash of red wine vinegar when your soup is done cooking. Season your soup with salt and pepper to taste, ladle it into bowls and dig in.
FAQ & Split Pea Soup Tips
- Leftovers of this soup keep great! Store them in a sealed container in the fridge for up to 3 days or in the freezer for up to 3 months. You may find that your soup thickens up quite a bit during storage — if this happens just add some water when you reheat it.
- Is this soup gluten-free? It is!
- Help! My soup has been cooking forever and the peas are still hard as rocks! Why?
- First off, keep in mind that this stuff does take a long time to cook. Have you given it a full hour and fifteen minutes? If not, be patient.
- Are your peas old? Check the date on the bag and consider how long they've been sitting in your pantry. Dated split peas often won't cook fully.
- Finally, did you add any extra seasonings? Acidic ingredients like lemon juice or vinegar can prevent split peas from cooking. This is why the red wine vinegar goes in at the end of this recipe.
- Do the peas need to be soaked before cooking? Nope! You can soak them overnight if you'd like though. It should shorten the cooking time a bit.
- Can this soup be made in a slow cooker? I'm sure it can, but I haven't tried, so I can't give exact instructions.

Had a wild Saturday night, so decided to make this. It turned out really delicious, thanks for the recipe Alissa!
Small things I changed were:
- One box of veg broth isn't enough cups so I used a little more water
- Used three stalks of celery, a larger onion, and two large carrots (unpeeled because it doesn't make a difference in soup)
- 5 cloves of garlic
- Doubled the smoke flavor
- Only had some cherry wine, and apple cider vinegar, so I mixed both.
Did I already say it was delicious?! It IS!
Ha! I made this last night too! I'm so glad you enjoyed it. Thanks Rodney!
Was great for the weather here. My (still) meat eating brother enjoyed it too!
Absolutely loved this soup. A sure hit with my family too even those Non Vegan loved it. I omitted the oil to make it WFPBNO. A new family favorite! Thank you!
That's so great to hear! I'm glad it was a hit!
Made this over holidays and again as popular now with meat eating family. Who knew! So delicious and I love the ease of making it too.
Thank you for great recipe!
That's awesome! I'm so glad it's a hit! Thanks Karen!
Wow this soup is game changer! A delicious healthy and hearty meal ready in an hour and a half start to finish. The only thing I did different was after the 40 minute mark, when the peas had absorbed most of the broth, I put a lid on and finished cooking that way. I didn’t have to add more water or broth and it didn’t water down the flavour. Delicious!
Love the recipe! I used more garlic! I wish I didn’t add the vinegar and smoke, I preferred the flavor before I did those add ins!
This was delicious! Thank you! I just had a problem with the liquid boiling down too much. I ended up having to add about 2 c of broth so there would be more of a base. It may be me though... it is hard to balance simmering and cooking the peas without evaporrating the liquid.
I would definately make this again! Thank you!
Glad you liked it! And it's not you - that always happens. The instructions suggest keeping a bowl of water by the stove so you can add it as the liquid dries up. Broth works too, but the soup could get too salty if you add a lot.
This was very good! One change - I sauteed the garlic with cumin and some mushrooms I was looking to use up and added at the end. Very delicious!
I made this as is, minus the liquid smoke, since I've never used it & don't know if I like it. It was wonderful without! Will definitely make this soup again and again!
Seriously, I almost cried eating this. My Italian neighbour's split pea soup was the greatest treat growing up. Being vegetarian, the only thing I crave is ham. Haha, so needless to say, pea soup is not the same without the giant, salted & smoked ham bone. This, was pretty freaking close. Thanks, food friend. It is delicious. I will be making this again.
Hi, delicious. Thanks for sharing. I did add 1/2 teaspoon of ground cloves to add another layer of flavor.
Amazing soup!! I ate 2 bowls of it tonight & loved every minute of it.
I can’t believe I used to like split pea soup from a CAN! Never again. 😁
Really great. Thanks for sharing. I didn't have any carrots, so I used sweet potato instead. Also, didn't have liquid smoke, so I used a dried chipotle pepper. Turned out great!
The soup was good, but there was too much cumin in it. I am not sure if I just had really pungent cumin or not. I balanced it out with some garlic powder and nutmeg. I also added smoked paprika, more liquid smoke, black pepper, and red pepper flakes after I made the soup per instructions. This fixed the overwhelming cumin taste, and gave it an extra flavor punch. Thank you for sharing your recipe, it has definitely put split oeas back on the menu since my body no longer tolerates any pork products!
