Soups & Stews
This vegan split pea soup recipe delivers the kind of hearty, earthy comfort that warms you from the inside out—especially when you add that smoky garlic depth. The secret lies in proper soaking and slow simmering, which transforms simple dried peas into a rich, velvety broth packed with plant-based protein.
I’ve tested this version countless times, and it never fails to impress, whether you’re serving it at a family gathering or enjoying a quiet weeknight dinner.

The split peas are the star here—green split peas have that classic earthy flavor, but yellow work too. Soak them overnight (or quick-soak with boiling water) to cut down on cooking time. Trader Joe's and Whole Foods carry good quality dried peas in bulk bins. The roasted garlic is non-negotiable—it adds that deep, smoky sweetness that makes this soup sing. Grab a head of garlic, wrap it in foil with a drizzle of oil, and roast at 400°F for 20 minutes before squeezing out the cloves. For the veggies, carrots and celery should be chopped into similar sizes so they cook evenly.
No smoked paprika? Regular paprika plus a pinch of liquid smoke works in a pinch. Short on thyme? Dried oregano at half the amount gets you close. The tomato paste can be swapped for 1 cup of crushed tomatoes if you prefer a chunkier texture. For extra richness, stir in 2 tablespoons of nutritional yeast at the end—it adds a cheesy depth without dairy. If you're using a pressure cooker, reduce the broth by 1 cup since the peas will absorb less liquid under pressure. The lemon juice at the end is crucial—it brightens all those earthy flavors and cuts through the richness.
This soup tastes even better the next day as the flavors meld. Store in the fridge for up to 5 days or freeze for 3 months. For freezing, cool completely first and portion into airtight containers. The roasted garlic cloves can be prepped ahead and stored in the fridge for 1 week wrapped in plastic. Garnish with fresh parsley just before serving—it adds a pop of color and freshness that makes the whole dish feel special. Serve with crusty bread or a simple green salad for a complete meal.

Step-by-step instructions for earthy split pea soup
This method delivers rich, smoky flavors with tender split peas—perfect for cozy meals.
Prepare the Vegetables and Roast the Garlic
Pick through the 1.5 cups dried green split peas to remove any small stones or debris. Rinse them briefly under cold water, then set aside. In a large bowl, combine the diced yellow onion, chopped carrots, and diced celery stalks (including leafy parts). Toss them with 2 tablespoons extra-virgin olive oil, 1 teaspoon smoked paprika, 0.5 teaspoon ground cumin, and 1 teaspoon sea salt. Spread this mixture on a baking sheet in an even layer.
Wrap the 6 whole garlic cloves tightly in aluminum foil and place them on the same baking sheet. Roast everything together at 400°F for 20-25 minutes, stirring the vegetables halfway through. The garlic should be soft and golden when done—this adds incredible smoky depth to the soup. Remove the garlic and let it cool slightly before squeezing the flesh out of the skins.
Sauté the Vegetables and Build the Base
Heat a large Dutch oven or heavy pot over medium heat. Add the roasted vegetables (including the garlic) and cook for 5-7 minutes, stirring occasionally, until they begin to soften and release their moisture. The onions should turn translucent, and the carrots and celery should start to caramelize slightly—this builds the foundation of flavor.
Stir in the 2 tablespoons tomato paste and cook for another 2 minutes, allowing it to deepen in color. This step intensifies the umami flavor and gives the soup its rich, earthy character. Be careful not to let it burn—keep the heat at medium and stir frequently.
Simmer the Split Peas with Broth and Aromatics
Add the rinsed 1.5 cups dried green split peas to the pot, along with the 4 cups vegetable broth. Bring everything to a boil, then reduce the heat to low and let it simmer gently for 45-50 minutes. Stir occasionally to prevent the peas from sticking to the bottom of the pot. The split peas should soften and thicken the soup naturally—this is where the magic happens.
After 45 minutes, stir in the 0.25 cup fresh thyme leaves and the remaining 0.5 teaspoon sea salt. Taste the soup and adjust the seasoning if needed. The split peas should be tender but still hold their shape slightly—if they're too mushy, they've absorbed too much liquid. If the soup is too thick, add a splash of water or broth to reach your desired consistency.
Finish with Brightness and Garnish
Remove the pot from the heat and stir in the 1 tablespoon fresh lemon juice. This brightens the flavors and cuts through the richness of the split peas and roasted garlic. Taste again and adjust the seasoning with black peppercorns if needed—freshly cracked pepper adds a nice contrast to the smoky, earthy notes.
Ladle the soup into bowls and garnish each serving with 0.25 cup chopped fresh parsley. The parsley adds a pop of color and freshness, balancing the deep, smoky flavors. Serve immediately with crusty bread or a side salad—this soup is best enjoyed warm and fresh from the pot.
Rest and Serve for Maximum Comfort
Let the soup sit for 5-10 minutes before serving if possible. This allows the flavors to meld even more, creating a cohesive and comforting dish. The split peas will continue to absorb the broth, making the soup richer and more flavorful with each passing minute.
This method ensures a hearty, earthy split pea soup with layers of smoky garlic and bright lemon notes—perfect for cozy nights in. The key is patience: letting the split peas simmer gently and the flavors develop naturally. Enjoy your bowl of warmth and comfort!
Pro Tips For Making Splitpea Soup
- SOAK THE PEAS: I learned this the hard way—skipping the soak means your soup will fight you for hours. Toss the dried peas in cold water for at least 4 hours (or overnight) to cut cooking time by nearly half. Just drain and rinse before adding them to the pot—no need to pre-cook.
- SWEEAT THE VEGETABLES: Don’t just chop and toss the onion, carrots, and celery. Cook them in a dry pot over medium heat for 5 minutes first—this draws out moisture and deepens their flavor. Add a pinch of salt here, too; it’ll make the whole soup taste richer later.
- SKIP THE BOIL: The moment you add the peas, the water should simmer gently—not roar like a pressure cooker. Too much heat toughens the peas and makes them split unevenly. Keep it at a low boil, and stir occasionally to prevent scorching at the bottom.
- SALT IN LAYERS: I used to dump all the salt at once, then wonder why the soup tasted flat. Instead, add half the salt when you start the vegetables, another pinch when the peas go in, and finish with the rest at the end. This balances flavor as the soup develops—no guessing needed.
Dietary considerations for these flavors
Vegan-Friendly Foundation
This split pea soup is naturally plant-based, relying on the peas' inherent protein and the rich umami from roasted garlic and tomato paste. The 1.5 cups dried green split peas provide a whopping 30 grams of protein per serving, making it a complete meal.
I skip dairy entirely but add nutritional yeast for a cheesy depth if desired. The smoked paprika and cumin give it that hearty, earthy character without any animal products. 🌱
Gluten-Free Adaptations
Since this recipe uses basic vegetables, broth, and spices, it's already gluten-free. Just ensure your vegetable broth is certified gluten-free—I recommend Pacific Foods or Imagine brands. The split peas themselves are naturally gluten-free, so no substitutions are needed.
For extra thickness, blend ½ cup of the soup and stir it back in instead of using flour-based thickeners. 🥄
Allergen Considerations
For nut allergies, this recipe is safe as long as you avoid cross-contamination. If you're also avoiding soy, check your smoked paprika and broth labels—some brands use soy-based anti-caking agents.
For sesame allergies, ensure your olive oil is sesame-free. The biggest watch-out is the vegetable broth, so always verify the ingredients list. 🚨
Low-FODMAP Options
To make this soup low-FODMAP, reduce the garlic to 2 cloves (roasted) and omit the onion, replacing it with 1 cup chopped leek greens (green parts only). Use low-FODMAP vegetable broth like Paleo Broth and reduce the split peas to 1 cup to lower fermentable content.
The carrots and celery are safe in moderate amounts. 🌿
High-Protein Boost
For extra protein, stir in ½ cup cooked lentils or 1 cup crumbled tempeh at the end. I also like adding 2 tablespoons hemp seeds per serving—they blend right in and add a nutty flavor.
For a creamy texture without dairy, blend in ½ cup silken tofu at the end. These additions keep the dish vegan while making it even more satisfying. 💪
Kid-Friendly Tweaks
To make this soup more appealing to picky eaters, blend it until smooth and serve with crusty bread for dipping. Reduce the smoked paprika to ½ teaspoon and add ½ teaspoon cinnamon for sweetness.
I also stir in 1 cup diced sweet potatoes along with the carrots—they add natural sweetness that kids often enjoy. 👶

Frequently asked questions
Why should I soak the split peas before cooking?
Soaking reduces cooking time by 30-50% and prevents that mushy texture. For best results, soak 1.5 cups dried peas in water overnight (8+ hours) or use the quick method: boil for 2 minutes, then let sit 1 hour. This also helps remove any bitter compounds, giving you a smoother flavor profile.
Can I use canned split peas instead of dried?
You can, but the texture and flavor won't be the same. Canned peas are pre-cooked and often contain added salt or preservatives. For a richer, more traditional taste, dried peas develop deeper flavor as they simmer. If using canned, reduce broth by 1 cup and simmer for only 15-20 minutes to avoid breaking them down too much.
How do I fix split peas that are too thick or too thin?
For thick soup, add ½ cup hot water or broth and simmer 5 minutes. For thin soup, blend ½ cup of the soup and stir it back in or simmer uncovered for 10 minutes to reduce. Stirring occasionally prevents sticking, but never skip the low heat—high heat makes peas gummy.
What's the best way to store leftover split pea soup?
Cool completely, then store in airtight containers for 5 days in the fridge or 3 months in the freezer. For freezing, leave ½ inch headspace to prevent ice crystals. Reheat gently on low heat, adding a splash of water if needed. The flavors actually improve overnight!
Can I make this soup in a slow cooker or Instant Pot?
For a slow cooker, combine all ingredients (except lemon juice) and cook on low for 6-8 hours or high for 3-4 hours. For an Instant Pot, sauté veggies first, then add everything else and pressure cook for 20 minutes on high. Natural release for 10 minutes, then stir in lemon juice. Both methods work beautifully!
