There’s something deeply comforting about starting the year with a pot of soup that has been quietly simmering while you slept. Every January 1st, I shuffle into the kitchen in my thickest socks, hair still tousled from last night’s celebrations, and lift the lid of my slow cooker. The steam that escapes carries the scent of smoky ham, earthy split peas, and sweet onions—a perfume that feels like a culinary reset button. This tradition began the year my grandmother passed; I wanted to taste the flavors she used to ladle into thick ceramic bowls while she told stories of growing up on a Minnesota farm. The soup was humble, nourishing, and—most importantly—patient. It asked nothing of me except time, and on the first morning of a brand-new year, that felt like the greatest gift I could give myself. Twelve years later, the ritual hasn’t changed: I still use her faded wooden spoon, still whisper “thank you” to the empty house, and still believe that if the first meal of the year is made with intention, the remaining 364 will follow suit.

Ingredients You'll Need

Split pea and ham soup is only as good as the sum of its parts, yet every ingredient is a supermarket staple. Look for green split peas in the dried-bean aisle; they break down into that signature moss-colored puree while retaining a whisper of texture. Avoid yellow split peas here—they’re starchier and will muddy the color. A smoked ham hock is the soul of the soup; the long, slow bath renders its collagen, giving the broth body and a gentle campfire perfume. If your grocery only has ham shanks, those work, but ask the butcher to saw the hock in half so the marrow can seep out. Yellow onions bring sweetness; dice them small so they melt into the backdrop. Carrots should be peeled—unpeeled skins can turn bitter over eight hours. I like the slender organic ones; they’re less woody at the core. Celery leaves, often discarded, go into the pot—they taste like concentrated celery. For herbs, dried thyme is more consistent than fresh after a long braise; crush it between your palms to wake up the oils. A single bay leaf whispers complexity, but remove it before serving—it’s a choking hazard and can overpower if left in the fridge. Finally, a modest splash of apple-cider vinegar at the end brightens the porridge-like richness without announcing itself.

How to Make New Year's Day Slow Cooker Split Pea and Ham Soup

Sort and rinse the split peas

Spread 1 pound (about 2¼ cups) of green split peas on a light-colored plate; pick out any pebbles or shriveled pieces. Transfer to a fine-mesh strainer and rinse under cold water until the runoff is clear—this removes dusty starch that can glue the peas together. Shake dry; no need to soak.

Build the base in the slow-cooker insert

Layer the rinsed peas, 1 large diced yellow onion, 2 medium peeled and diced carrots, 2 diced celery stalks plus leaves, 2 minced garlic cloves, 1 teaspoon dried thyme, ½ teaspoon freshly ground black pepper, and 1 bay leaf. Nestle 1½-pound smoked ham hock into the center like a savory meteor.

Add liquid, but not too much

Pour in 5 cups low-sodium chicken broth and 2 cups water. The solids should be barely submerged; peas swell dramatically, and excess liquid yields a watery soup. If you’re altitude cooking above 3,000 ft, add an extra ½ cup water to account for evaporation.

Set it and celebrate

Cover and cook on LOW for 8–9 hours or on HIGH for 5–6 hours. Resist peeking; each lift of the lid releases steam and adds 15–20 minutes to the cook time. The soup is ready when the peas have collapsed and the hock meat pulls away with a fork.

Shred the ham

Transfer the hock to a plate; discard skin, bones, and visible fat. Shred the meat with two forks, taking care to feel for stray cartilage. Return ham to the pot; discard bay leaf. For a silkier texture, pulse an immersion blender 3–4 times, but leave plenty of whole-pea texture.

Finish with brightness

Stir in 1 tablespoon apple-cider vinegar and a handful of fresh parsley. Taste; add salt only if needed—the ham usually provides enough. Serve hot with crusty rye or cornbread; garnish with a swirl of cream or a drizzle of chili oil for color.

Expert Tips

Salt at the end

Ham hocks vary in saltiness; seasoning early can lead to an over-salty finished soup. Wait until after shredding and tasting.

Quick-cool for safety

Divide leftovers into shallow containers so the soup drops through the danger zone (40–140 °F) within 2 hours.

Adjust thickness

Too thick? Thin with hot broth, not water. Too thin? Simmer on HIGH uncovered for 20 minutes or mash a cup of peas and return.

Overnight starter

Prep everything the night before; refrigerate the insert. In the morning, set it in the base and hit START—no extra prep needed.

Bone-saving trick

If you have leftover holiday ham bone, freeze it. Swap in place of the hock for a lighter smoke and a second life for your leftovers.

Double-batch bonus

Cook twice the amount; split peas are cheap and the soup freezes beautifully. You’ll thank yourself in February.

Variations to Try

Storage Tips

Refrigerator

Cool completely, then store in airtight containers up to 4 days. The soup will thicken; add broth or water when reheating.

Freezer

Ladle into pint freezer bags, squeeze out air, and freeze flat up to 3 months. Thaw overnight in the fridge or microwave from frozen, stirring often.

Frequently Asked Questions

No soaking required for split peas; they’re hulled and will cook down to creamy in the slow cooker. A quick rinse is plenty.

Yes, foaming is starches releasing. Stir once halfway if it bothers you; it will subside as the peas break down.

Absolutely. Dice 2 cups of ham steak and add it during the last hour so it stays tender but doesn’t dry out.

The peas may be old. Dried legumes older than 2 years never fully soften. Buy from a store with high turnover and use within 12 months.
