Ingredients You’ll Need

• 16 oz Green Split Peas
• 1 medium Onion – finely diced
• 2 cloves Garlic – minced
• 2 medium Yellow or Yukon Potatoes – peeled and cut into cubes
• 3 ribs Celery – diced
• 2 Tbsp Neutral Oil – like Avocado oil
• 2 small Carrots – diced
• 2 tsp Fresh Thyme – chopped
• 2 Bay Leaves
• 6 cups Vegetable Broth – or Vegan Chicken Broth
• 2 cups Water – to thin soup as needed
• 3 dashes Liquid Smoke – plus more to taste
• Pinch of Salt & Pepper – more if needed

Step-by-Step Cooking Method

1. Sort through the split peas to remove any stones or debris, then rinse well.
2. Heat the oil in a large pot over medium heat.
3. Add the diced onions and sauté 5–8 minutes, stirring occasionally, until translucent; season with salt and pepper.
4. Add the diced celery, minced garlic, chopped thyme, bay leaves, and split peas; cook 1–2 minutes until fragrant.
5. Pour in the vegetable broth, cover, and simmer gently over medium-low for 20–25 minutes, stirring occasionally, until the peas begin to break down.
6. Stir in the peeled, cubed potatoes, diced carrots, and liquid smoke.

7. Continue simmering 20–25 minutes, stirring occasionally, until the vegetables are tender and the soup has thickened.
8. If the soup becomes too thick, stir in up to 2 cups of water or broth to reach desired consistency.
9. Remove and discard the bay leaves.
10. Taste and adjust salt and pepper as needed.
11. Optional: Partially mash the soup or pulse briefly with an immersion blender to achieve your preferred texture.

Pro Tips for Best Results

• Always sort through and rinse your split peas before cooking to get rid of any stones or bits.
• Skip soaking the peas — they’ll soften perfectly as they simmer. Just note older peas might take a bit longer.
• Sautéing the onions slowly until translucent gives you a flavorful, sweet base that makes a big difference.
• Keep the soup simmering gently on medium-low, stirring occasionally to stop peas from sticking and burning on the pot bottom.
• Add salt near the end of cooking. Salting too soon can sometimes make peas take longer to soften.
• Be careful with liquid smoke—it’s strong. Start with what the recipe calls for, then add more little by little if you want a bigger smoky punch.
• Love a chunkier soup? Mash part of it or use short pulses with an immersion blender to keep some texture.
• If your soup gets too thick, thin it gently with broth or water until it’s just how you like it.

Add-Ins and Flavor Swaps

• Up the smoky factor by stirring in diced smoked tempeh, pan-fried vegan bacon, or sliced vegan sausage for added texture and oomph.
• Make it richer by swapping a cup of broth for full-fat coconut milk or stirring some in at the last minute.
• Boost the green goodness by tossing in chopped kale or spinach during the last five minutes of cooking.
• If you like a little heat or spice, try sprinkling in smoked paprika, cumin, or a dash of cayenne pepper.
• Try swapping green split peas for yellow ones for a milder, slightly sweeter taste — cooking time stays pretty much the same.
• If you’re not vegan, feel free to add diced cooked ham right before serving instead of the vegan options.

Storing, Freezing, and Reheating

• To store, cool the soup to room temperature, transfer it to an airtight container, and refrigerate for up to 3 to 4 days.
• For longer storage, freeze in portion-sized containers or freezer bags, leaving some space for expansion. It keeps well for about 3 months. Potatoes may change texture a bit after freezing, but the soup remains delicious.
• When ready to eat, thaw overnight in the fridge or reheat gently on the stovetop over low heat. Stir often and add a splash of broth or water to loosen it up if it thickened. Microwave reheating also works in short bursts with stirring in between.
• Because the soup thickens after sitting, thin with broth or water when reheating. For smoother results after freezing, blend the soup before freezing.

Answers to Common Questions

• Do I need to soak split peas? — Nope. Split peas are forgiving and soften while cooking without pre-soaking, usually in about 40 to 50 minutes.
• Can I use yellow split peas instead of green? — Absolutely! Yellow peas will give you a slightly sweeter, milder soup and a different color, but cook the same way.
• How do I know when the soup is done? — The split peas should be soft and starting to fall apart, potatoes and carrots tender, and the soup thickened to your liking. Taste and season before serving.
• Can I make this soup in a slow cooker or Instant Pot? — Yes! For slow cooker, sauté onions first, then cook everything on low for 6 to 8 hours. For Instant Pot, cook on high pressure for 10 to 12 minutes, then natural release, and adjust liquid as needed.
• Why does the soup sometimes scorch? — It’s usually heat that’s too high or peas sticking to the bottom. Keep heat medium-low and stir occasionally. Using a heavy-bottomed pot helps too.
• Can I freeze this soup? — Yes, it freezes beautifully for up to three months. The potatoes might soften a bit more, but adding broth when warming fixes the texture.
