If you’ve ever carved a holiday ham and stood there holding the bone, wondering whether to toss it or save it, this is the answer.
That bone is the entire flavor base of the best split pea soup you’ll make all year.
Split pea soup is one of the oldest, cheapest, and most forgiving soups. Dried split peas, smoked ham hocks, carrots, celery, onion, and thyme go into a crockpot in the morning.
By dinner, the peas have broken down into a thick, velvety, smoky soup that tastes as if it simmered on a stove all day — because in a sense, it did.
It’s also genuinely high-protein for a vegetable soup, at about 18–20g per bowl, because split peas are legumes and the ham adds protein. One pot, about 15 minutes of chopping, and no soaking required.
If you don’t have a ham bone, there’s a version below using ham hocks, diced ham, or smoked sausage. And if you want it vegan, there’s a version for that too.
Why This Split Pea Soup Crockpot Recipe Works
No soaking required. Unlike most dried beans, split peas don’t need soaking. Rinse them, pick them over, and add them straight to the pot.
Smoked ham hocks are the most reliable flavor base. A meaty ham bone works too, but ham hocks are more consistent — they’re uniformly smoky, they’re available year-round, and they have enough connective tissue to give the broth real body. Diced ham is the last resort because it contributes almost no collagen and doesn’t need 7 hours of cooking.
The peas break down on their own. Split peas are meant to disintegrate. That’s what makes the soup thick and creamy without any cream, roux, or cornstarch.
Add salt at the end, not at the beginning. Ham varies enormously in saltiness. Start with just ½ teaspoon and add more after you shred the ham; that’s the only reliable way to season the soup correctly.
Smoked paprika provides insurance. If your ham bone happens to be less smoky than expected, smoked paprika gives you the smoky depth that the ham was supposed to contribute.
Lemon at the end is not optional. A small amount of acid dramatically improves the finished soup. You won’t taste “lemon” — you’ll notice that the soup doesn’t taste heavy or flat.
It’s cheap. A pound of dried split peas costs about $2. Add ham hocks you’d otherwise throw away, a few vegetables, and you’ve got 8 servings of dinner for under $8 total.
It freezes beautifully. Split pea soup might be the single best soup for freezing. The texture doesn’t change when thawed because nothing delicate is in it.
It’s flexible—Crockpot, stovetop, Instant Pot, vegan, vegetarian, yellow split peas — all covered below.
Split Pea Soup Crockpot Recipe
A thick, smoky split pea soup made in the slow cooker with tender green split peas, meaty smoked ham, carrots, celery, onion, and herbs. No soaking is needed, and the peas slowly break down into a naturally creamy, satisfying soup.
Ingredients
- 1 lb dried green split peas, rinsed and picked over
- 1 meaty smoked ham bone or 1½ lbs smoked ham hocks
- 8½ cups low-sodium chicken broth, plus more if needed
- 3 medium carrots, peeled and diced
- 3 celery stalks, diced
- 1 large yellow onion, diced
- 3 cloves garlic, minced
- 1 tsp dried thyme
- ½ tsp dried marjoram or dried oregano
- ½ tsp smoked paprika
- 2 bay leaves
- ½ tsp kosher salt, plus more to taste
- ½ tsp freshly ground black pepper
- 1 tbsp fresh lemon juice, plus more to taste
- Fresh parsley or chives, for serving
Instructions
1. Rinse the split peas. Place the split peas in a colander and rinse thoroughly under cold running water. Pick through them and discard any shriveled peas, debris, or small stones. No soaking is necessary. Add the split peas directly to the slow cooker.
2. Add everything to the slow cooker. Add the rinsed split peas, smoked ham bone or ham hocks, chicken broth, carrots, celery, onion, garlic, thyme, marjoram, smoked paprika, bay leaves, salt, and black pepper to a 6-quart or larger slow cooker. Stir gently to distribute the ingredients. The ham does not need to be completely submerged.
3. Slow cook until the peas break down. Cover and cook on LOW for 7–8 hours or HIGH for 4–5 hours. The soup is done when the split peas have broken down substantially, the vegetables are tender, and the soup is thick and creamy. The peas should no longer have a firm or gritty center.
If the peas are still firm at the end of the cooking time, continue cooking until they are completely tender. Slow cookers vary, so doneness is more important than the exact cooking time.
4. Remove the ham and bay leaves. Carefully transfer the ham bone or ham hocks to a plate or cutting board. Remove the bay leaves from the soup. When the ham is cool enough to handle, pull the meat from the bone. Discard the bones, skin, excess fat, and cartilage, then shred or chop the meat into bite-size pieces. Return the meat to the slow cooker and stir it into the soup.
5. Adjust the consistency. Check the soup before serving. It should be thick and creamy but still easy to ladle and spoon. If it is thicker than you like, stir in hot broth or water ½ cup at a time until it reaches your preferred consistency. If it seems thinner than expected, leave the slow cooker uncovered and cook on HIGH for 15–30 minutes, stirring occasionally, until it thickens. Keep in mind that split pea soup will thicken considerably as it cools.
6. Finish the seasoning. Taste the soup after adding the ham back in. Add more salt if needed, keeping in mind that ham's saltiness can vary considerably. Add more black pepper if desired.
Stir in the lemon juice at the end. Start with 1 tablespoon, taste, and add another small splash if the soup still tastes heavy or flat. The lemon should brighten the soup without making it taste lemony.
7. Serve. Ladle the hot soup into bowls and garnish with fresh parsley or chives. Serve with crusty bread, toasted sourdough, or a grilled cheese sandwich.
Notes
Protein: About 18–20g per serving, depending on the amount of ham used
Stovetop Split Pea Soup (Faster Version)
If you don’t want to wait 8 hours, the stovetop version takes about 90 minutes.
Instructions:
1. Heat 2 tbsp olive oil or butter in a large Dutch oven over medium heat. Add the onion, carrots, and celery and cook 6–8 minutes, until softened. Add the garlic and cook for 30 seconds.
2. Add the rinsed split peas, ham bone or ham hocks, 8½ cups broth, thyme, marjoram, smoked paprika, bay leaves, ½ tsp salt, and pepper. Bring to a boil.
3. Reduce the heat to low, cover, and simmer 60–75 minutes, stirring occasionally, until the peas have completely broken down. Stir more often in the last 20 minutes — split pea soup scorches easily on the bottom once it thickens.
4. Remove the ham bone, shred the meat, and return it to the pot. Discard the bone and bay leaves. Taste, adjust salt, and finish with lemon juice.
5. Serve.
Total time: About 1 hour 30 minutes.
Vegan Split Pea Soup Crockpot Version
Split pea soup is easy to make vegan, and it’s still a solid protein source because split peas do the work on their own.
Swaps:
- Omit the ham bone, ham hocks, or diced ham entirely.
- Use 8½ cups vegetable broth instead of chicken broth.
- Increase the smoked paprika to 1 tbsp for the smoky depth that ham usually provides.
- Add 1 tsp liquid smoke (optional, but it’s the closest thing to ham flavor without ham)
- Keep the lemon juice at the end — it’s even more important without the ham.
Everything else stays the same. Cook on LOW for 7–8 hours, taste, and adjust salt.
Protein: About 14–16g per serving from the split peas alone.
Add a protein boost: Stir in 1 cup of cooked barley or 1 can of drained white beans in the last 30 minutes.
Yellow Split Pea Soup Variation
Yellow split peas work exactly like green ones, with two differences:
Flavor: Slightly sweeter and milder than green split peas.
Color: The finished soup is a golden yellow rather than green. It looks more like a potage than a classic split pea soup.
Cooking time is the same. 7–8 hours on LOW. Everything else in the recipe stays the same.
If Using Diced Ham Instead
You can substitute about 2 cups diced cooked ham for the ham bone or ham hocks, but the soup will have less smoky, rich flavor because the bone and connective tissue are no longer contributing to the broth.
For the best flavor with diced ham, add it during the last 30–60 minutes of cooking rather than cooking it for the entire 7–8 hours. Diced ham doesn’t need long cooking, and adding it late keeps it from turning mushy.
Taste carefully before adding extra salt because prepared ham can already be quite salty.
Do You Need to Soak Split Peas?
No. Split peas don’t need soaking, and soaking actually works against you here. Split peas are meant to break down completely during cooking, and soaked peas break down faster — sometimes so fast they turn to paste before the ham flavor has time to develop.
What you should do instead:
- Rinse them under cold water.
- Pick through them for stones or shriveled peas.
- Add them dry to the crockpot.
That’s it. No overnight soak, no pre-cooking.
How Thick Should Split Pea Soup Be?
This is the most common question about split pea soup, and the answer is: thicker than you think, but not solid.
The right consistency: It should mound slightly on a spoon and hold its shape for a second before spreading. It shouldn’t stand up like mashed potatoes, and it shouldn’t run off the spoon like broth.
If it’s too thick: Stir in hot broth or water ½ cup at a time. The soup will also thin slightly as it cools if you add liquid.
If it’s too thin: Uncover and cook on HIGH for 15–30 minutes. Split peas will keep absorbing liquid and thicken as they cook.
Note: Split pea soup thickens significantly overnight in the fridge. What looks perfect at dinner will be nearly solid the next morning. Always add a splash of broth or water when reheating.
Toppings and Serving Suggestions
Split pea soup is rich and heavy on its own, so the right toppings add contrast:
- Croutons — homemade or store-bought, for crunch
- Crispy bacon or pancetta — crumbled on top
- Diced ham — extra protein and a smoky finish
- Sour cream or Greek yogurt — a cooling swirl
- Fresh chives or parsley — bright green contrast
- A squeeze of lemon — wakes up the whole bowl.
- Toasted pumpkin seeds — texture and crunch
- Swirl of olive oil — a finishing touch
- A drizzle of sherry vinegar — classic French touch
What to serve with it:
- Crusty bread or a baguette
- Grilled cheese
- Cornbread
- A simple green salad
- Rye bread with butter
Storage and Reheating
Refrigerator: Store in an airtight container for up to 5 days. It thickens as it sits — add broth or water when reheating.
Freezer: Split pea soup freezes well. Store in airtight containers or freezer bags for up to 3 months. The texture doesn’t change on thaw because there’s nothing delicate in it.
To freeze in portions: Ladle into 2-cup containers or quart-sized freezer bags, press flat, and freeze flat. They stack and thaw in about 4 hours in the fridge.
Reheating: Split pea soup thickens significantly when refrigerated. Reheat gently on the stovetop or in the microwave, stirring occasionally. Add a splash of broth or water as needed until the soup returns to a spoonable consistency.
Do not freeze with toppings. Add croutons, sour cream, and fresh herbs after reheating.
Frequently Asked Questions
Do you have to soak split peas for crockpot soup?
No. Split peas cook from dry in a slow cooker without soaking. Rinse them and pick out any stones, then add them directly to the crockpot. Soaking makes them break down too quickly and can turn the soup to paste.
How long does split pea soup take in a crockpot?
7–8 hours on LOW, or 4–5 hours on HIGH. The peas are done when they’ve completely broken down, the vegetables are tender, and the soup is thick and creamy. The peas should no longer have a firm or gritty center.
What’s the best ham for split pea soup?
Meaty smoked ham hocks are the most reliable choice — they’re consistently smoky and have the collagen that gives the broth body. A meaty ham bone works well if you have one. Diced ham is the last resort because it contributes much less flavor and shouldn’t be cooked for the full time.
Can I make split pea soup without a ham bone?
Yes. Use 1½ lbs smoked ham hocks, 2 cups diced ham (added in the last 30–60 minutes), 1 lb smoked sausage, or even 1 lb of bacon ends and pieces. For a vegan version, use smoked paprika and liquid smoke for the smoky depth.
Can I use yellow split peas instead of green?
Yes. They cook the same and taste slightly sweeter and milder. The soup will be golden yellow instead of green.
Why is my split pea soup not thick?
The peas haven’t broken down enough yet. Cook longer on HIGH, uncovered, for 15–30 minutes, and stir occasionally. If the peas are still whole after 8 hours on LOW, your crockpot may be running cool —switch to HIGH for another hour.
Why is my split pea soup too thick?
Split pea soup thickens significantly as it cools and especially overnight in the fridge. Stir in hot broth or water ½ cup at a time until it reaches your desired consistency.
Why does my split pea soup taste flat?
Two possibilities. First, it may need more salt — but taste first, since ham varies enormously in saltiness. Second, it may need acid. A tablespoon of fresh lemon juice at the end is what keeps the soup from tasting heavy. If it still tastes flat after salt and lemon, add another pinch of smoked paprika.
Can I add potatoes?
Yes. Add 2 medium Yukon Gold potatoes, diced, at the start. They’ll break down and make the soup even thicker. This is a classic addition in some regional versions.
Can I use chicken broth instead of water?
Yes, and it’s better. Chicken broth adds depth that water doesn’t. Use 8½ cups total, or half broth and half water for a lighter flavor.
Is split pea soup healthy?
Yes. It’s high in fiber and protein, low in fat, and made almost entirely from vegetables and legumes. One bowl has about 18–20g protein and 10–12g fiber. Watch sodium if you’re using a salty ham bone and salty broth.
Can I make this in an Instant Pot?
Yes. Sauté the vegetables, add the peas, ham hocks, broth, and seasonings, then pressure cook for 15 minutes with a natural release. Remove the ham, shred the meat, and return it to the pot. Total time is about 40 minutes.
How long does split pea soup last in the fridge?
Up to 5 days in an airtight container. It thickens as it sits, so add broth when reheating.

The Bottom Line
Split pea soup is the rare soup that’s cheap, high-protein, freezer-friendly, and genuinely delicious — and the crockpot makes it almost effortless. Smoked ham hocks, a pound of dried split peas, and a few vegetables do all the work.
No soaking. No roux. No cream. Just 15 minutes of chopping and 7 hours of hands-off cooking. The peas break down into a thick, smoky, velvety soup that costs about $8 for 8 servings.
Three things to remember: start with just ½ teaspoon of salt, finish with lemon juice, and expect it to thicken overnight. Do those, and this becomes the soup you make every time you’ve got smoked ham hocks in the fridge.
