Ingredients Needed

Here is what you will need to create this delicious soup:

2 tablespoons extra-virgin olive oil
1 large onion (diced)
2 ribs celery (diced)
4 cloves garlic (finely chopped)
1 lb. potatoes (diced into 1/2″ pieces (see notes))
1 lb. dry split peas (rinsed)
8 cups vegetable broth (or chicken broth)
kosher salt and black pepper (to taste)
1/4 cup chopped fresh dill
2-4 tablespoons fresh squeezed lemon juice

Ingredient Notes & Substitutions

When it comes to potatoes, I find Russet potatoes break down beautifully, adding a creamy texture to your Vegetarian Split Pea Soup. Yukon Gold potatoes, on the other hand, hold their shape a bit more and offer a slightly waxier texture. Dicing them into small, 1/2 inch pieces ensures they cook evenly and integrate well into the soup.

For the split peas, you will typically find green or yellow split peas. Green split peas have a slightly sweeter and more earthy flavor, which I prefer for this recipe. Yellow split peas tend to be milder and cook a little faster. Both work wonderfully for a hearty Vegetarian Split Pea Soup.

When using vegetable broth, especially store-bought options, I always recommend checking the sodium levels. Opt for a low-sodium vegetable broth to have more control over the final seasoning of your Vegetarian Split Pea Soup. Chicken broth can be used if you are not strictly vegetarian.

Any good quality cooking oil will work in place of extra-virgin olive oil. Avocado oil is another excellent choice for its mild flavor and high smoke point.

This recipe is easily made vegan simply by ensuring you use vegetable broth. It is already naturally gluten-free, making it a fantastic choice for various dietary needs.

How to Make Vegetarian Split Pea Soup

Making this comforting Vegetarian Split Pea Soup is a straightforward and rewarding process. Follow these steps for a perfect bowl every time.

Phase 1: Sauté Aromatics

First, warm 2 tablespoons of extra-virgin olive oil in a large pot or Dutch oven over medium heat. Add the diced onion and celery, and sauté them until they are softened and slightly translucent, which usually takes about 3 minutes.

Next, add the finely chopped garlic to the pot. Sauté for just 30 seconds more, or until it becomes wonderfully fragrant. Be careful not to burn the garlic, as it can quickly turn bitter and affect the entire flavor of your Vegetarian Split Pea Soup.

Phase 2: Simmer and Cook

Pour in the 8 cups of vegetable broth, then add the rinsed dry split peas and the diced potatoes to the pot. Give everything a good stir to combine. Season generously with kosher salt and black pepper to taste.

Bring the mixture to a rolling boil over medium-high heat. Once boiling, reduce the heat to low, cover the pot, and let your Vegetarian Split Pea Soup simmer for 1 to 1.5 hours, or until the split peas are completely tender. The split peas should be falling apart and the soup should have thickened considerably. If the soup gets too thick during simmering, simply add a little more broth to reach your desired consistency.

Phase 3: Finish and Serve

Turn off the heat from the stove. Stir in the 1/4 cup of fresh chopped dill and 2 to 4 tablespoons of fresh squeezed lemon juice, depending on how lemony you prefer your soup. Adding the dill and lemon at this stage helps to preserve their fresh flavor and bright aroma, preventing them from cooking out.

Finally, taste the Vegetarian Split Pea Soup and adjust the seasoning as necessary. You may find it needs a little more salt or pepper. If the soup still seems too thick, a bit more water or vegetable broth can be stirred in. Serve your hearty Vegetarian Split Pea Soup with an extra drizzle of olive oil and another squeeze of fresh lemon juice, if you want.

Freezing and Reheating Instructions

This Vegetarian Split Pea Soup freezes beautifully, making it perfect for meal prep.

For freezing, allow the soup to cool completely to room temperature first. This prevents ice crystals from forming and preserves the texture. Ladle individual portions into airtight freezer-safe containers or heavy-duty freezer bags. Make sure to leave a little headspace, as liquids expand when frozen. Properly stored, your Vegetarian Split Pea Soup will last for up to 3 months in the freezer.

To reheat, the best method is to thaw the soup overnight in the refrigerator. Once thawed, you can reheat it gradually on the stovetop over medium-low heat, stirring occasionally until warmed through. Alternatively, microwave individual portions in 30-second intervals, stirring between each, until hot. The consistency of the Vegetarian Split Pea Soup may change slightly after freezing, so be prepared to add a splash of vegetable broth or water if it is too thick for your liking.

Pro Tips & Troubleshooting

Here are some of my expert tips to ensure your Vegetarian Split Pea Soup is perfect, along with advice for common issues.

Pro Tips

When sautéing the garlic, remember that garlic burns easily. Keep a close eye on it and sauté it for only a brief period, just until it is fragrant. This ensures a sweet, aromatic flavor rather than a bitter one.

For the potatoes, if you are using thin-skinned varieties like Yukon Gold, there is no need to peel them. The skins add extra fiber and nutrients, and they soften beautifully into the soup.

Always taste and adjust the liquid as you go. You can easily adjust the thickness of your Vegetarian Split Pea Soup with more broth or water, aiming for your desired consistency.

When adding smoked paprika and liquid smoke, start with the recommended amounts. Taste the soup and adjust to your preference. A little goes a long way to provide that deep, smoky umami flavor.

Season your soup in stages. Add some salt and pepper at the beginning, but taste and adjust again at the end. This prevents over-seasoning and ensures a balanced flavor in your Vegetarian Split Pea Soup.

For a creamier consistency, use an immersion blender to blend a portion of the soup directly in the pot, or transfer some to a regular blender (carefully!) and then return it to the pot. This is great for those who prefer a smoother soup.

Common Mistakes to Avoid

A common pitfall is burning the garlic. This can impart a bitter, acrid taste to the entire soup, which is hard to fix. Always keep the heat moderate and stir frequently when the garlic is in the pot.

Do not be afraid to adjust the liquid amount. If your soup is too thick, add more broth or water. If it is too thin, let it simmer uncovered for a bit longer to reduce.

Split pea soup needs generous seasoning to truly shine. Make sure to taste and add enough kosher salt and black pepper throughout the cooking process. Under-seasoning will leave your Vegetarian Split Pea Soup bland.

Ensure the peas are fully tender. Inadequate cooking time will result in gritty or firm split peas, detracting from the soup’s comforting texture. Simmer patiently until they are falling apart.

Serving & Storage

This hearty Vegetarian Split Pea Soup is a meal in itself, but it pairs wonderfully with a few simple additions.

Serving Ideas

Serve your smoky Vegetarian Split Pea Soup with a crusty slice of artisanal bread for dipping. A classic grilled cheese sandwich is also a perfect pairing, especially on a chilly day. A light side salad with a tangy vinaigrette offers a refreshing contrast to the richness of the soup.

To garnish, a drizzle of high-quality extra-virgin olive oil adds a beautiful sheen and richness. A sprinkle of fresh chopped dill enhances the herbal notes. If you are not vegan, a dollop of plain Greek yogurt or sour cream adds a creamy tang. Do not forget that final squeeze of fresh lemon juice; it brightens all the flavors and adds a zesty finish. For a delicious crunchy topping, consider adding some crispy garlic baked chickpeas.

Storage and Make-Ahead

Leftover Vegetarian Split Pea Soup can be stored in an airtight container in the refrigerator for up to 3 to 4 days. It often tastes even better the next day as the flavors have more time to meld.

For longer storage, please refer back to the detailed “Freezing and Reheating Instructions” section above. This Vegetarian Split Pea Soup is excellent for meal prep.

FAQ

Do you need to soak split peas for soup?

You do not strictly need to soak dry split peas for soup. They cook down perfectly without soaking. Soaking can reduce the cooking time slightly, but it is not essential for this Vegetarian Split Pea Soup recipe. If you choose to soak them, reduce the simmering time by about 20-30 minutes.

How do you make vegetarian split pea soup in an Instant Pot or slow cooker?

For an Instant Pot, follow the sauté steps, then add all remaining ingredients except dill and lemon juice. Cook on High Pressure for 15 minutes, then allow a natural pressure release for 10-15 minutes before quick releasing any remaining pressure. Stir in dill and lemon juice. For a slow cooker, follow the sauté steps in a separate pan, then transfer to the slow cooker with remaining ingredients (except dill and lemon). Cook on low for 6-8 hours or high for 3-4 hours, or until peas are tender. Stir in dill and lemon juice before serving.

What kind of potatoes are best for split pea soup?

Russet potatoes are excellent for split pea soup because they break down easily, contributing to a creamy texture. Yukon Gold potatoes also work well, offering a slightly firmer texture while still becoming tender. Either choice will make a delicious Vegetarian Split Pea Soup.

Store leftover Vegetarian Split Pea Soup in an airtight container in the refrigerator for up to 3-4 days. It also freezes well for up to 3 months.

How can I thicken or thin my split pea soup?

If your Vegetarian Split Pea Soup is too thin, simply simmer it uncovered for a bit longer to allow some of the liquid to evaporate and the peas to break down further. If it is too thick, stir in more vegetable broth or water until it reaches your desired consistency.

What are the benefits of adding lemon and dill to split pea soup?

Adding fresh lemon juice and dill at the end of cooking brightens the flavors of the Vegetarian Split Pea Soup significantly. The lemon provides a zesty counterpoint to the richness, while the dill adds a fresh, herbaceous aroma and taste that prevents the soup from feeling heavy.
