Split Pea Soup That Turns One Ham Bone Into Four Dinners

After a holiday ham or a Sunday ham dinner, the bone usually goes straight in the trash with some meat still clinging to it. That bone is worth keeping. Simmered with a pound of dried split peas and a few vegetables, it makes a big pot of thick, smoky soup: eight servings, or four dinners for a household of two.

Split peas are among the cheapest foods in the dried bean aisle and need no soaking. They cook down on their own into a creamy soup, so there is no blender required. The ham bone supplies the salt, smoke and body that make it taste like it took all day.

Serves: 8 · Prep: 15 min · Cook: 1 hr 30 min · Keeps: 3 to 4 days in the fridge

🧾 Ingredients

• 1 meaty ham bone (from a bone-in ham), or 2 smoked ham hocks (about 1 1/2 lb total)
• 1 lb (450 g, about 2 1/4 cups) dried green split peas, rinsed and picked over
• 1 tablespoon vegetable oil or butter
• 1 large onion, diced
• 2 medium carrots, diced
• 2 celery ribs, diced
• 3 garlic cloves, minced
• 9 cups (2.1 liters) water, plus more if needed
• 2 bay leaves
• 1 teaspoon dried thyme
• 1/2 teaspoon black pepper
• Salt, only at the end
• 1 to 2 teaspoons cider vinegar or lemon juice (optional, to finish)
• 1 to 2 cups diced leftover ham, if the bone has little meat (optional)

👩‍🍳 Step by step

1. Rinse and check the peas. Put them in a strainer, rinse under cold water, and spread them on a plate to look for small stones or debris. No soaking needed; split peas are already hulled and halved, so they soften quickly.
2. Soften the vegetables. Heat the oil in a large (at least 6-quart) pot over medium heat. Add the onion, carrots and celery and cook 6 to 8 minutes until softened. Add the garlic for the last minute.
3. Add bone, peas, water and seasonings. Add the ham bone, peas, water, bay leaves, thyme and pepper. Do not add salt yet: the ham releases salt as it cooks, and the soup reduces.
4. Bring to a boil, then simmer. Once boiling, skim off any foam, lower the heat and simmer with the lid slightly ajar.
5. Stir every 15 minutes. Split peas sink and can scorch on the bottom as they thicken. Scrape the bottom with each stir.
6. Cook until the peas collapse, about 1 hour 15 minutes to 1 hour 30 minutes. They should be completely soft and breaking apart, giving a thick, creamy soup.
7. Pull the meat. Remove the bone and bay leaves. When the bone is cool enough to handle, pull off the meat, chop it, and return it to the pot. Discard the bone, fat and gristle.
8. Adjust and season. Stir well; for a smoother soup, whisk vigorously or mash with a potato masher. Thin with hot water if needed. Taste, add salt only if necessary, and stir in a little vinegar to brighten the flavor.

What can go wrong

The peas are still firm after 90 minutes. Older dried peas take longer, and hard water slows softening. Keep simmering, adding water as needed, and check every 15 minutes.

It burned on the bottom. Do not stir the burnt layer into the soup. Pour the unburned soup into a clean pot and continue there.

It is too salty. Some ham bones and hocks are very salty. Add water plus a peeled, diced potato and simmer until the potato is tender. Next time, taste before any salt goes in.

It turned into paste overnight. That is normal for split pea soup. Add water when reheating, about 1/4 cup per serving.

🔁 What can I swap?

• Ham hocks or smoked turkey wings instead of a ham bone. They are often sold near the bacon and cost little per pound. Hocks have less meat, so add diced ham at the end if you want more.
• No ham at all: Use 1 teaspoon smoked paprika, 1 extra tablespoon oil and 2 bouillon cubes. A couple of strips of chopped bacon cooked with the onion also add smoke.
• Yellow split peas: Same timing, slightly milder flavor and a golden color.
• Extra vegetables: Add a diced potato with the water for a heartier soup, or stir in a handful of frozen peas at the end.
• Pressure cooker: Cook on high pressure for 15 minutes with natural release for 15 minutes; use 1 cup less water because nothing evaporates.
• Slow cooker: Cook on low 7 to 8 hours or high 4 to 5 hours, until the peas break down.

💵 Why is it one of the cheapest soups?

You already paid for the ham, so the bone is free flavor. A pound of dried split peas is inexpensive and yields eight hearty servings once cooked with vegetables and water. Onions, carrots and celery round out a soup that needs no broth, cream or cheese.

How to price your pot:

If you buy hocks instead of using a leftover bone, add their price; the cost per bowl usually still stays low.

Tip: Not ready to make soup? Freeze the ham bone in a zip-top bag and label it with the date. When you have a free afternoon, it goes straight from the freezer into the pot; just add 10 to 15 minutes to the simmer.

🧊 How do I cool, store and freeze it safely?

A big pot of thick soup holds heat for hours, which keeps it in the temperature range where bacteria grow. The USDA's leftovers and food safety page uses a pot of soup as its own example: divide it into smaller, shallow containers so it cools quickly, and refrigerate leftovers within 2 hours.

• Fridge: The FoodSafety.gov cold storage chart lists soups and stews with meat at 3 to 4 days.
• Freezer: 2 to 3 months for best quality, according to the same chart. Freeze in 2-serving containers so one thaws in time for dinner for two.
• Reheat: Bring it to a rolling boil, the USDA method for soups, adding water as you stir.
• The ham bone itself: The same chart gives cooked, store-wrapped ham 3 to 5 days in the fridge, so if the soup is not happening this week, freeze the bone.

🍞 How do I make four dinners feel different?

• Night 1: Classic bowls with crackers or toast.
• Night 2: Thinned with a little water and served over a baked potato, topped with shredded cheese.
• Night 3: With skillet flatbread or grilled cheese for dipping.
• Night 4: Topped with crispy croutons made from stale bread (cube, toss with oil, bake at 375 °F for 10 minutes) and a drizzle of hot sauce or a spoon of yogurt.

🏁 The bottom line

A ham bone, a pound of split peas and a few vegetables make eight bowls of thick, smoky soup with nearly no effort. Skip the soaking, hold the salt until the end, stir often so it does not stick, and cool the pot quickly in shallow containers. Freeze half and you have dinners ready for weeks.

❓ Frequently Asked Questions

Do I have to soak split peas?

No. Split peas cook in about an hour and a half without soaking. Soaking can shorten the time slightly, but it is not needed for a creamy result.

Can I use a spiral-cut ham bone?

Yes. Spiral-cut and other bone-in hams both work. Glazed hams may add a hint of sweetness, which most people enjoy; rinse off heavy glaze if you prefer a savory soup.

How much water should I add when reheating?

Start with about 1/4 cup per serving and add more as you stir. The soup thickens a lot as it chills, and it will loosen again as it heats.

Can I make it without a ham bone?

Yes. Use smoked turkey, a little bacon, or smoked paprika and bouillon for a vegetarian version. Taste and salt more carefully, since the bone usually supplies most of the salt.
