There’s a certain kind of magic that happens when the first real chill of autumn sneaks under the door and the light turns that buttery-gold. My grandmother called it “soup weather,” and she believed—quite seriously—that if you could master one humble pot of split-pea soup, you could feed a family through anything: job layoffs, surprise orthodontist bills, or the year the furnace gave up on Thanksgiving weekend. This version, made in the Instant Pot, is my love letter to her frugal genius, updated for the weeknight chaos of 2024. It costs less than a large latte to make the whole pot, simmers away while I help with algebra homework, and tastes like someone wrapped you in the world’s softest blanket. I’ve served it to company (with a loaf of crusty bread and a crisp salad) and watched the bowl come back to the kitchen scraped clean. I’ve also portioned it into lunch jars for my husband’s construction crew—those jars always come home empty, often with a note scribbled on the lid: “Need this recipe.” Today, I’m finally writing it down for you.

Why This Recipe Works

One-Pot Wonder: Everything—from sautéing the vegetables to pressure-cooking the peas—happens in the same stainless insert. No extra pans to wash.
Under-a-Dollar Servings: A 1-lb bag of split peas and a smoked-ham hock together cost about $3.50 and yield eight hearty bowls.
No-Soak Peas: The pressure cooker softens the peas in 15 minutes; no overnight soaking required.
Freezer-Friendly: The texture stays silky even after thawing, making it perfect for batch-cooking Sundays.
Vegetable-Loaded: Three whole carrots, three ribs of celery, and an onion disappear into the puree—great for picky eaters.
Smoky Depth Without Gourmet Prices: A $2 ham hock (or leftover holiday ham bone) infuses restaurant-level flavor.

Ingredients You'll Need

Split peas are the quiet heroes of the legume aisle. They look like tiny disks of jade and cook down into velvet because their outer skin has already been removed. I reach for green split peas—they hold their color better than yellow ones and have a milder, earthier flavor that plays nicely with smoky pork. If all you can find is yellow, proceed anyway; the soup will simply look golden.

The ham hock (sometimes labeled “pork hock” or “smoked hock”) is the knobby joint just above the pig’s back ankle. It’s rich in collagen, which melts under pressure and gives the soup body that dairy never could. Look for hocks that are deep rose inside the packaging, not gray, and that have a generous ring of skin—more skin equals more gelatin. If your grocery only stocks giant turkey–sized hocks, ask the butcher to saw one in half; they’ll happily oblige. Leftover holiday ham bone works too—just save the fatty rind.

Vegetables need to be diced small so they vanish into the puree. I use the food processor: pulse carrots and celery into rice-sized pieces in five seconds flat. A standard mirepoix ratio (2:1:1 onion/carrot/celery) keeps the soup balanced, but I sneak in an extra carrot for sweetness so I can limit added salt.

Chicken stock is preferable to water, but if you’re keeping costs razor-thin, 6 cups of water plus 2 teaspoons of “Better Than Bouillon” roasted chicken base equals the same depth. Avoid low-sodium stock unless you’ve tasted your ham hock first; some brands are so salty they’ll make the finished soup inedible.

Herbs should be sturdy. I tie 3 sprigs of thyme, 2 bay leaves, and a handful of parsley stems into a little cheesecloth bundle so I can fish it out easily. Dried thyme works—use ¾ teaspoon—but add it with the vegetables so the volatile oils rehydrate.

Finally, a splash of apple-cider vinegar at the end brightens everything. If you don’t have cider vinegar, lemon juice is fine, but use half the amount.

How to Make Budget Friendly Split Pea and Ham Soup in the Instant Pot

Prep the aromatics

Set the Instant Pot to “Sauté” on “Normal.” When the display reads “Hot,” add 2 tablespoons of neutral oil (canola or sunflower). Swirl to coat, then scatter in 1 diced medium yellow onion. Cook 3 minutes, stirring, until the edges turn translucent. Add 3 minced garlic cloves and cook 45 seconds—just until the garlic smells fragrant and loses its raw edge. Garlic burns fast, so keep it moving.

Build the base

Stir in the diced carrots and celery plus ½ teaspoon freshly ground black pepper. Cook 4 minutes. The vegetables should sweat, not brown; if you see browning, splash in 2 tablespoons of the stock to deglaze. Add 1 pound (about 2¼ cups) of rinsed green split peas and toss to coat in the fragrant oil. Toasting the peas for 60 seconds deepens their nutty flavor.

Nestle the ham hock

Nestle 1 smoked ham hock (or 2 small ones) into the pea mixture. Pour in 6 cups chicken stock. The liquid should just cover the hock; add water up to the 6-cup mark if you’re short. Add the herb bundle and 2 dried bay leaves. Do not salt yet—the ham hock will release its sodium as it cooks.

Pressure-cook

Cancel “Sauté.” Lock the lid, set the valve to “Sealing,” and select “Manual” or “Pressure Cook” on “High” for 15 minutes. The pot will take 10–12 minutes to come to pressure—use this time to unload the dishwasher or set the table.

Natural release

When the timer beeps, let the pressure release naturally for 15 minutes. This extra time allows the peas to finish softening and the collagen to fully dissolve. After 15 minutes, carefully turn the valve to “Venting” to release any remaining steam.

Fish out the hock

Open the lid and transfer the ham hock to a plate. It will be falling-apart tender. When cool enough to handle, shred the meat with two forks, discarding skin, bones, and large fat pockets. Chop the meat into bite-size pieces.

Blend (optional but dreamy)

For a silky bistro texture, immersion-blend the soup right in the pot for 10 seconds—just enough to break down about half the peas. Like it chunky? Skip this step. Return the shredded ham to the pot.

Season and serve

Stir in 1 tablespoon apple-cider vinegar. Taste: add salt only if needed and a few grinds of fresh pepper. Ladle into warm bowls and garnish with chopped parsley or, if you’re feeling fancy, a swirl of cream and a few homemade croutons.

Expert Tips

Keep it flowing

If the soup thickens on standing (peas are thirsty), loosen with a splash of water or milk when reheating.

Freeze in muffin tins

Portion cooled soup into silicone muffin trays, freeze, then pop out and store in a bag for single-serve blocks that thaw in minutes.

Overnight flavor bump

Make the soup on Sunday; the flavors marry and intensify overnight. Reheat gently with a splash of broth.

Stretch the meat

If your hock is skimpy, add ½ cup of diced leftover ham after pressure-cooking for meatier bites without extra cost.

Vegan shortcut

Omit the ham, substitute ½ teaspoon smoked paprika, and use vegetable stock for a meat-free version that still tastes smoky.

Buy in bulk

Split peas keep for a year in an airtight jar. Buy the 2-lb bag, split with a friend, and you’ve got pantry insurance.

Variations to Try

Curried Pea Soup: Add 1 tablespoon mild curry powder with the onions and swap the vinegar for lime juice. Garnish with cilantro.
Potato & Pea: Replace one carrot with a diced russet potato for extra creaminess.
Spring Green: Stir in 2 cups baby spinach after blending; the residual heat wilts it perfectly.
Spicy Cajun: Add ½ teaspoon cayenne and a diced green bell pepper. Serve with hot sauce and rice.
Maple-Kissed: Swap the vinegar for 1 tablespoon maple syrup and add a pinch of cinnamon for a Canadian twist.

Storage Tips

Refrigerate: Cool the soup completely, transfer to airtight containers, and refrigerate up to 4 days. The texture will thicken; thin with water or broth when reheating.

Freeze: Ladle into pint-size freezer bags, squeeze out excess air, and lay flat to freeze up to 3 months. Thaw overnight in the fridge or microwave from frozen at 50 % power, stirring every 2 minutes.

Make-ahead lunches: Portion soup into 12-oz mason jars, leaving 1 inch of headspace. Freeze without lids; once solid, screw on lids to prevent ice crystals. Grab a jar on the way out the door; it’ll be thawed by noon and can be reheated in the office microwave.

Frequently Asked Questions

Yes. Sauté the vegetables on the stovetop first, then transfer everything to the slow cooker. Cook on LOW 7–8 hours or HIGH 4–5 hours until the peas fall apart. Blend and season as directed.

Not at all. Traditional split-pea soup is left chunky. Blending half gives you a creamy base with tender bits of pea and ham—best of both worlds—but skip it if you prefer texture.

Drop in a peeled potato and simmer 10 minutes; the potato will absorb some salt. Remove the potato, or better yet, dilute with water or unsalted broth and adjust seasonings.

Only if you have an 8-quart Instant Pot. The peas expand and foam; filling past the ½ line risks clogging the valve. For smaller pots, make two batches and combine them after cooking.

Yes, but check cross-contamination statements on the bag if you’re celiac. Also verify that your stock and bouillon are certified gluten-free.

Set the pot to “Sauté” and simmer uncovered 5–10 minutes, stirring, until reduced. Alternatively, ladle 1 cup of soup into a small bowl, whisk in 1 tablespoon cornstarch until smooth, then stir the slurry back into the pot and simmer 2 minutes to thicken.
