Every year after Easter, my grandpa would turn the leftover ham bone into the coziest pot of split pea soup, and he always bragged that it only took three ingredients. This slow cooker version is my busy-week twist on his post-holiday trick: just dried split peas, water, and that meaty ham bone (or hock) doing all the heavy lifting. It simmers away while you work, and by dinnertime you’ve got a thick, velvety green soup with tender chunks of ham and a rich, smoky flavor—no chopping, no fuss, and perfect for stretching leftovers into another comforting meal.
Ladle the hot split pea soup straight from the slow cooker into bowls and serve with crusty bread, cornbread, or buttered toast for dunking. A simple green salad or roasted vegetables on the side helps balance the richness. If you like a little contrast, add a splash of vinegar or a squeeze of lemon at the table, and offer black pepper or red pepper flakes for anyone who wants extra warmth. Leftovers make an easy lunch—just reheat gently and thin with a splash of water if it’s thickened overnight.
Slow Cooker 3-Ingredient Split Pea SoupServings: 6
Ingredients
1 pound (about 2 1/4 cups) dried green split peas, rinsed and picked over
1 meaty leftover ham bone or ham hock (about 1 1/2 to 2 pounds, with some meat attached)
8 cups water
Directions
Rinse the dried split peas in a fine-mesh strainer under cool running water, picking out any small stones or debris. This quick step helps keep the soup smooth and clean-tasting.
Place the rinsed split peas in the bottom of a 5- to 7-quart slow cooker, spreading them into an even layer so they cook evenly and form that thick, creamy base.
Nestle the meaty ham bone or ham hock right on top of the peas. Try to position it so some of the meat is submerged in the peas and water; this helps the flavor and those tender ham chunks distribute through the soup.
Pour the 8 cups of water over the ham and peas. The water should cover the peas by at least 1 to 2 inches; if your slow cooker is wide and shallow, you can add up to 1 extra cup of water to ensure everything is mostly submerged.
Cover the slow cooker with the lid and cook on LOW for 8 to 10 hours, or on HIGH for 4 to 5 hours, until the split peas are very soft and breaking down and the soup looks thick and creamy. Avoid lifting the lid often, as that releases heat and can lengthen the cooking time.
Once the peas are fully tender, carefully remove the ham bone or hock to a cutting board using tongs. Let it cool for a few minutes until it’s comfortable to handle, then pull off any remaining ham, discarding fat, gristle, and the bone.
Chop or shred the ham into bite-size pieces and return it to the slow cooker, stirring it through the soup so you get those pink, savory bites in every scoop. At this point the soup should be thick, with a velvety green base and visible chunks of ham.
Stir the soup well to combine the peas and ham and to smooth out any remaining whole peas. If the soup is too thick for your liking, stir in a small splash of hot water until it reaches your preferred consistency. Taste and, if needed, add a tiny pinch of salt at the table—many ham bones are salty enough on their own.
Serve the soup hot straight from the slow cooker, letting it sit on the WARM setting if you’re feeding people over a couple of hours. Steam should be rising from the surface, and the texture should be hearty and spoon-coating, perfect for dipping bread.
Variations & Tips
If you have more leftover ham than just the bone, you can add up to 1 extra cup of diced cooked ham to the slow cooker in the last hour of cooking for even more meaty bites. For a slightly smokier flavor, use a smoked ham hock or shank instead of a traditional ham bone. If you prefer an ultra-smooth soup, use an immersion blender to partially blend the soup in the slow cooker before adding the chopped ham back in—blend carefully and briefly so you still keep some texture. To make this more herb-forward without adding extra ingredients during cooking, finish individual bowls with a sprinkle of dried or fresh herbs you already have on hand, like parsley or thyme. For a lighter texture, thin leftover soup with a bit of water or low-sodium broth as you reheat; split pea soup thickens considerably as it cools.
Food safety tips: Cool leftovers quickly by transferring the soup to shallow containers before refrigerating; do not leave the soup at room temperature for more than 2 hours. Store in the refrigerator for up to 3 to 4 days, or freeze for up to 3 months. Reheat gently on the stovetop or in the microwave until the soup is steaming hot throughout (165°F/74°C). When handling the hot ham bone, let it cool slightly and use utensils or gloves if needed to avoid burns. Always start with a cooked ham bone or fully cooked ham hock from a reliable source, and discard the bone and any meat that has an off smell or slimy texture.
