Ingredients for This Hearty Vegan Pea Soup
This is a flexible, use-what-feels-good kind of soup. The vegetables do not need to be chopped perfectly because they will soften beautifully under pressure.
- Olive oil
- 1 shallot, roughly chopped
- 2 jalapeño peppers, chopped, or sweet pepper or bell pepper for a mild version
- 3 cloves garlic, chopped a little more finely
- Celery, including the leaves
- Carrot, chopped
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 cup soaked barley
- 1 cup soaked yellow dried peas
- 1 teaspoon vegetable or no-chicken bouillon, or another flavor booster
- 2 to 3 cups vegetable stock, water, or a combination
- About 1/2 bunch parsley, stems included
- About 1 handful fresh mint
- A squeeze of fresh lemon juice
If you have vegetable stock, use it. If not, water works just fine when you add something with a little extra oomph, like vegetable bouillon, mushroom-flavored seasoning, or even Marmite. No need to get precious about it.
Build a Fragrant Vegetable Base
Start by roughly chopping the shallot, jalapeños, garlic, celery, and carrot. A rustic chop is perfect here. Everything is going to simmer and soften, so tiny, painstakingly uniform pieces are absolutely not necessary.
I love jalapeños in winter soup because that little bit of heat is so warming. But if spice is not your thing, swap them for sweet peppers or use about half a bell pepper instead. Make it yours.
Do not toss those celery leaves. They have a beautiful flavor and bring extra freshness to the pot. Celery is wonderfully fragrant in soup, and using both the stalks and leaves is an easy way to make the most of it.
Sweat the Vegetables Before Adding the Peas
Heat olive oil in a pot. The pot can be the removable insert from your Instant Pot if it is safe to use on the stovetop. Add the shallot, celery, garlic, peppers, carrots, and celery leaves.
Season with 1 teaspoon salt and 1/2 teaspoon black pepper. Stir everything around and let the vegetables sweat until they begin to soften and release that gorgeous fragrance.
This quick step builds the flavor base. It is a simple little thing, but it makes a big difference. You want the vegetables softened, colorful, and smelling like something very good is on its way.
Add Soaked Barley and Yellow Peas
Once the vegetables have softened, add 1 cup soaked barley. Stir it through the vegetables and let it become part of the party.
Then add 1 cup soaked yellow dried peas. This combination is what gives the soup its satisfying texture. The peas cook down into a creamy, comforting base while the barley adds body and a little chew.
Stir everything together well. At this point, the pot should already smell pretty fragrant, and honestly, it only gets better from here.
Give the Broth a Little Extra Oomph
Add about 1 teaspoon bouillon. Vegetable bouillon is lovely, and no-chicken bouillon is also a great choice. Use what you have on hand.
There are plenty of ways to add more savory depth to plant-based soups:
- Vegetable stock
- Vegetable bouillon paste or cubes
- No-chicken bouillon
- Mushroom-flavored bouillon or seasoning
- A little Marmite, if you have it
Add 2 to 3 cups of vegetable stock, water, or a combination, then stir everything together. The liquid should bring all the vegetables, barley, and peas together into a proper soup situation.
Pressure Cook for 10 Minutes
Transfer the insert to the Instant Pot, set it to the soup setting, and cook at high pressure for 10 minutes.
That is enough time for the yellow peas to become soft and creamy while the vegetables settle into the broth. When you open the pot, you are looking for a soup that feels luxurious, thickened, and completely comforting.
Finish with Parsley, Mint, and Lemon
While the soup cooks, chop about half a bunch of parsley. Use the stems too because they are full of flavor. Fresh herbs are not just decoration here, they are a major part of what makes this soup so fabulous.
Once the soup is done, stir in the parsley generously. You can never really go wrong with greens in a pot of soup.
Next, chop and add about a handful of fresh mint. Mint may sound unexpected in a pea soup, but it is so fragrant and lovely here. It gives the hearty barley and pea base a bright, fresh lift.
Finally, squeeze in a little lemon juice and stir. The lemon wakes everything up and brings the herbs, vegetables, and creamy peas together beautifully.
A Creamy, Herby Bowl of Comfort
Give the soup a taste after the herbs and lemon go in. It should be creamy from the peas, hearty from the barley, fragrant from the celery and herbs, and just bright enough from the lemon.
If you like a little extra spice, the jalapeños bring a gentle warming heat. If you made it with sweet peppers instead, it will still be rich, cozy, and deeply flavorful. Either way, this is a seriously good vegan soup for a cold day, a budget-friendly meal, or whenever you want something wholesome that feels a little bit special.
Simple Tips for Making It Your Own
- Prefer mild soup? Replace jalapeños with sweet peppers or bell pepper.
- Use the celery leaves. They add real flavor and should not go to waste.
- Soak the barley and peas first. This is the approach used here before pressure cooking.
- Use what you have. Water, stock, bouillon, mushroom seasoning, or Marmite can all bring extra savory flavor.
- Add the herbs at the end. Parsley, mint, and lemon stay fresh and vibrant when stirred in after cooking.
This is soup that tastes even better when you let the herbs do their thing. Creamy, fragrant, green, lemony, and so, so good.
