JUMP TO RECIPE

Instant Pot split pea soup features hearty ingredients and smoky ham flavor for a satisfying meal the whole family will love. The pressure cooker shaves so much time from this recipe, and makes this gluten- and dairy-free pea soup recipe so easy to make!

Lentil soup’s less popular BFF (at least by number of Google searches), split pea soup brings the same thick and creamy texture made in a flash in an electric pressure cooker.

I’m a soup year-rounder so I made this Instant Pot split pea soup several times over the summer, but felt a little funny sharing it with you when it was a million degrees outside. Even though it’s made in the Instant Pot and doesn’t heat up your kitchen with hours of cook time on the stove.

Just wasn’t feeling inspired to write a bunch of words about a soup recipe in the middle of summer, you know?

As with many pressure cooker recipes like my fav smoky Instant Pot lentil soup, this Instant Pot split pea soup is quick (16 minutes of pressure cook time) and EASY. It’s a healthy soup recipe with lots of fiber to keep you full for a long while afterwards. I speak from experience when I say it makes the best leftover lunch.

And we all know how good a day can go when you’re excited about your lunch.

Split pea prep

As with many dried legumes, the split peas require a little prep work before you can throw them in the Instant Pot.

First they need to be sorted. Now, when I first started getting into using dried beans and peas I had no idea what I was looking for. I’d stir them around a few times and go, “yeah, looks good”. But after managing to find a small rock in a batch with my haphazard sorting, I started paying more attention.

You want to remove any rocks (obviously), shriveled up, misshapen, or otherwise “off-looking” peas, or any other detritus that ended up in the bag with the peas. My procedure is now pouring the dried peas out onto a plate or kitchen towel in a single layer and giving everything a good look over.

Next give the sorted split peas a good rinse with cool water. Up until recently, for reasons I’m not sure about, I was getting by in the kitchen with a small mesh strainer. This meant I’d need to rinse beans, peas, or quinoa in 4-5 batches. Since buying a large strainer in an inexpensive set (affiliate link), I can rinse everything at once. It’s the little things that make a big difference sometimes!

Now your peas are good to go – no soaking required.

How to make Instant Pot split pea soup

Once the peas are sorted and rinsed, I’d argue that the hard work is behind you.

You’ll start the cooking process by heating olive oil in the Instant Pot and sautéing the onion, carrots, celery, garlic, and spices. After years of using a super basic slow cooker for “off-stove” recipes, it still wows me that you can brown and sauté things right in the Instant Pot insert. Hell-ooooooo, less dishes to wash.

Once your vegetables are softened, it’s important to scrape up any burnt bits from the bottom of the Instant Pot insert before adding the rest of the ingredients and pressure cooking. This helps prevent the dreaded “burn” message you might have read about or experienced on the Instant Pot. To do this I pour in a little bit of the liquid (one-third cup of broth or so, doesn’t have to be exact) to do a quick and dirty deglazing of the pan.

Once that’s done, pour in the rest of the broth, water, split peas, ham, and a bay leaf. Lock the lid, set the valve to “sealing”, and select the Manual function for 16 minutes. Easy as that.

What kind of ham to use in split pea soup

I like to use smoked ham shanks in this Instant Pot split pea soup. While you can use ham hocks if that’s more convenient, I like the meatier shanks to help give this soup some heft. Anywhere between 1 – 1.5 pounds of ham shanks is my recommendation (keep in mind that’s the weight including bones), though there’s definitely wiggle room here.

Once the soup has finished cooking and the pressure has released naturally, fish out the super tender ham shanks, remove the bone segments, and cut them into bite-sized pieces to be added back to the soup for serving. There will likely be excess fatty bits on the shanks that you can remove at your discretion, too.

And oh yeah, don’t forget to remove the bay leaf!

During cooking, the split peas break down beautifully and become ultra tender and creamy. No immersion blending of any kind was done here. With perfectly softened vegetables and smoky ham, this is one hearty soup recipe that has the ability to keep you full for hours.

What to serve with split pea soup

One touch that instantly makes a soup feel ~*luxe*~ is to drizzle some extra-virgin olive oil over top when serving. I need to update my potato and white bean soup recipe card to show this as a heavy recommend, not just an optional one.

Also so good as a split pea soup topper? Croutons. The ones you see here are homemade and detailed in my how to make croutons post. Baking them low and slow is key in getting them perfectly crisped and light without too much browning. My favorite bread for croutons? An Italian five grain baguette, hands down.

If you’re looking for a more substantial soup accessory, a grilled cheese is a great one. This havarti grilled cheese is on sourdough bread and includes roasted poblano peppers and caramelized onions for extra bite.

Recipe notes:

I have a 6-quart Instant Pot (affiliate link), so that’s the size used in testing this recipe. While I don’t have personal experience with the larger Instant Pot, I would imagine the significant liquid content of this recipe would be just fine to make in an 8-quart IP, too.
You’ll find leftover split pea soup thickens up a lot in the refrigerator. I simply stir a little water into the soup before reheating to bring it back to the right consistency.
