Smoky Vegetarian Split Pea Soup

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.
