Traditional Split Pea Soup

Why This Traditional Split Pea Soup Works

As the pot simmers on low heat, the split peas slowly break down. At first they look like separate little pieces, but over the 90 minutes they soften so much that they start to fall apart and melt into the liquid. That’s what turns the broth into a thick, creamy soup without adding any cream or flour. Stirring now and then keeps the peas from sticking to the bottom and helps them spread through the pot.

While everything cooks, the ham hock or diced ham sits in the hot liquid and gives off its salt and smoky taste. The long, gentle simmer loosens the meat on the ham hock so it becomes tender enough to shred and stir back in. At the same time, the onion, celery, and carrots soften until they almost blend into the peas, so the soup is smooth with a few soft bites of vegetables and ham. By the end, the peas have thickened the whole pot, and the soup holds together in a hearty, spoon-coating way.

Mistakes To Avoid

Letting the soup simmer on very high heat instead of a gentle low simmer can make the peas catch on the bottom of the pot before they soften. The bottom layer burns and sticks, and once that happens the whole pot takes on a scorched smell and gritty bits of burnt pea.

Skipping the rinse on the split peas often leaves extra dust and starch in the pot. The soup then foams a lot, gets gummy on the surface, and can thicken in a clumpy way instead of turning smooth and creamy.

Adding salt early, especially when using a ham hock or salty broth, can slow down how fast the peas soften. The peas stay a bit hard in the center even after a long time, so the soup ends up thin with little hard pellets instead of a thick, soft texture.

Stirring only once or twice during the 90 minutes can cause uneven cooking. The peas at the bottom break down into mush while the ones near the top stay whole, so the soup looks patchy and has a mix of paste-like and firm bites.
