The short answer: Split pea soup is a thick, smoky soup made from dried split peas, a ham bone and a few vegetables, and the peas don't need soaking.

Rinse 1 pound of dried green split peas and simmer them with a ham bone or 2 smoked hocks, 1 diced onion, 2 carrots, 2 celery ribs, 3 garlic cloves, a bay leaf and 8 cups of water or low-sodium broth for 1½ to 2 hours, stirring often, until the peas fall apart. Shred the meat back in, add diced ham and salt to taste. It makes about 8 servings. Below are the steps, a slow cooker version, texture fixes and storage.

I love cooking, and I love a pot of soup that turns a leftover holiday ham bone into another dinner.

What goes into split pea soup

Ingredient Amount Swap
Dried green split peas 1 pound Yellow split peas (milder)
Ham bone with some meat 1 2 smoked ham hocks or a smoked turkey leg
Diced cooked ham 1 to 2 cups Skip for a lighter soup
Olive oil or butter 1 tablespoon
Onion 1 large, diced
Carrots 2, diced
Celery 2 ribs, diced
Garlic 3 cloves, minced
Water or low-sodium broth 8 cups Chicken or vegetable
Bay leaf 1
Dried thyme ½ teaspoon

How to make split pea soup, step by step

  1. Rinse the peas in a colander and pick out any stones or shriveled peas.
  2. Cook the vegetables. Warm the oil in a heavy pot over medium heat and cook the onion, carrots and celery for 6 minutes. Add the garlic for 1 minute.
  3. Add everything else. Stir in the peas, ham bone, water or broth, bay leaf, thyme and pepper.
  4. Simmer. Bring it to a boil, lower the heat and simmer partly covered for 1½ to 2 hours. Stir every 15 minutes, scraping the bottom, because split peas settle and scorch.
  5. Shred. Lift out the bone, pull off the meat and chop it. Discard the bone and bay leaf.
  6. Finish. Stir in the meat and diced ham. Mash or blend to the texture you like, then taste and add salt.

Stovetop, slow cooker or pressure cooker

Method Liquid Time Note
Stovetop 8 cups 1½ to 2 hours Stir often so it doesn't stick
Slow cooker 7 cups Low 8 hours or high 4 to 5 hours Mostly hands-off
Electric pressure cooker 6 cups 15 minutes at high pressure, natural release Can foam, so don't overfill

Getting the texture right

  • Chunky: skip blending and just stir hard at the end; the peas break down on their own.
  • Silky: blend half with an immersion blender, then stir in the ham.
  • Too thick: add hot broth ½ cup at a time. It thickens more as it sits.
  • Too thin: simmer uncovered for 20 minutes.
  • Too salty: add water and a diced potato and simmer for 15 minutes.

Make it your way

  • Vegetarian: skip the ham, use vegetable broth and add 1 teaspoon of smoked paprika and a splash of soy sauce for depth.
  • Extra vegetables: add a diced potato or parsnip with the carrots.
  • Bright finish: a squeeze of lemon or a splash of vinegar right before serving.
  • Toppings: croutons, crumbled bacon, a swirl of sour cream or chopped parsley.

Storing and freezing

The USDA's leftovers guidance says to get cooked food into the fridge within 2 hours, and to split a big pot into shallow containers so it cools fast. FoodSafety.gov's cold storage chart gives soups with meat 3 to 4 days in the fridge and 2 to 3 months in the freezer. If the holiday ham bone can't become soup this week, the USDA's ham safety page covers how long cooked ham keeps, and the bone can go in the freezer until soup day.

Frequently asked questions

How do you make split pea soup? You make split pea soup by rinsing 1 pound of dried green split peas and simmering them with a ham bone or hock, a diced onion, 2 carrots, 2 celery ribs, garlic, a bay leaf and 8 cups of water or low-sodium broth for 1½ to 2 hours, until the peas break down. Stir in diced ham and season at the end.

Do you need to soak split peas? No, split peas don't need soaking. They're already hulled and split, so they soften and break down in 1½ to 2 hours of simmering. Just rinse them and pick out any small stones.

How do you make split pea soup thicker? You can make split pea soup thicker by simmering it uncovered for the last 20 to 30 minutes, or by blending part of it. It also thickens a lot as it cools, so stop a little thinner than you want it.

Why isn't my split pea soup getting soft? Split peas stay firm when they're old or when acid or too much salt goes in early. Keep simmering, add water as needed, and hold back tomatoes, vinegar and most of the salt until the peas are soft.

Can you make split pea soup in a slow cooker? Yes, put rinsed peas, the ham bone or hock, diced vegetables, garlic, herbs and 7 cups of broth in a slow cooker. Cook on low for 8 hours or high for 4 to 5 hours, then remove the bone, shred the meat and stir.

What can I use instead of a ham bone? Use 2 smoked ham hocks, a smoked turkey leg, or 2 cups of diced ham plus ½ teaspoon of smoked paprika. For a vegetarian soup, use vegetable broth and smoked paprika.

Is split pea soup healthy? Split pea soup is a filling, high-fiber meal, since dried peas are rich in fiber and plant protein. Use low-sodium broth and taste before salting, because ham adds a lot of salt.

How long does split pea soup last in the fridge? Split pea soup lasts 3 to 4 days in the fridge. Cool it in shallow containers and refrigerate it within 2 hours of cooking.

Can you freeze split pea soup? Yes, split pea soup freezes well for 2 to 3 months. Thaw it in the fridge and thin it with water or broth when you reheat it, because it thickens in the freezer.

How do I fit soup night into my weekly plan? Pick one night for soup and one night for its leftovers when you plan the week. The Meal Planner & Grocery List from HomeBase Paper Co. ($3.99) shows both nights and the short shopping list together.
