After extensive testing, I’ve perfected this pressure cooker method to transform simple ingredients into a hearty, soul-warming meal that’s perfect for chilly evenings. The Instant Pot not only speeds up the process but also infuses every spoonful with rich, savory notes.

Ingredients

The beauty of this split pea soup lies in its simple, wholesome ingredients. Using a good-quality broth and fresh vegetables builds a fantastic flavor base, while the smoked paprika adds a wonderful depth even without the ham.

1 tablespoon olive oil
1 tablespoon butter
1/2 medium onion (chopped)
2 medium carrots (chopped)
2 sticks celery (chopped)
2 cloves garlic (minced)
6 cups vegetable or chicken broth
1 pound green split peas
1 pound smoked ham (chopped (optional))
1 teaspoon smoked paprika
1/4 teaspoon ground cumin
Salt & pepper (to taste)

Timing

Prep Time	15 minutes
Cook Time	20 minutes (plus pressure release)
Total Time	About 45 minutes

Context: This method reduces the total cook time by over 60% compared to simmering a pot on the stove for hours. It’s a fantastic make-ahead option, as the flavors meld and deepen beautifully overnight, making it perfect for meal prep.

Step-by-Step Instructions

Step 1 — Sauté the Aromatics

Select the “Sauté” function on your Instant Pot and add the olive oil and butter. Once hot, add the chopped onion, carrots, and celery. Sautéing, which means cooking quickly in a small amount of fat over medium-high heat, softens the vegetables and builds a flavor foundation. Cook for 5-7 minutes, until the onions are translucent. Add the minced garlic and cook for one more minute until fragrant.

Step 2 — Deglaze the Pot

Pour in about 1/2 cup of the broth and use a wooden spoon to scrape up any browned bits stuck to the bottom of the pot. This crucial step, called deglazing, incorporates those flavorful fond into the soup and helps prevent a “burn” warning from the Instant Pot.

Step 3 — Add Remaining Ingredients

Add the remaining broth, the green split peas, the chopped smoked ham (if using), smoked paprika, and ground cumin to the pot. Do not add salt yet if using a salty ham or broth. Give everything a good stir to combine.

Step 4 — Pressure Cook

Secure the lid on the Instant Pot, ensuring the steam release valve is set to “Sealing.” Cancel the Sauté function, then select “Manual” or “Pressure Cook” on High pressure. Set the timer for 15 minutes. The pot will take about 10-15 minutes to come to pressure before the countdown begins.

Step 5 — Natural Pressure Release

Once the cooking cycle is complete, allow the pressure to release naturally for 15 minutes. This continued gentle cooking helps the peas break down completely for a creamy texture. After 15 minutes, carefully turn the steam release valve to “Venting” to release any remaining pressure.

Step 6 — Season and Serve

Open the lid carefully, stirring the soup. The split peas should be completely soft and the soup thick. In my tests, I’ve found the consistency can vary; if it’s too thick, stir in a little hot water or broth. Now is the time to taste and season with salt and black pepper as needed. Serve hot for a comforting and complete meal.

Healthier Alternatives

Turkey Ham or Smoked Turkey Leg — Reduces saturated fat while maintaining the classic smoky flavor. Shred the meat after cooking for perfect texture.
Vegetarian “Ham” or Smoked Tofu — A great plant-based protein swap that mimics the savory, smoky notes without any meat.
Low-Sodium Broth & No Added Salt — Gives you complete control over sodium levels. Season at the end with herbs like thyme or a squeeze of lemon for brightness.
Add Leafy Greens — Stir in a few handfuls of chopped spinach or kale after pressure cooking for extra vitamins and a pop of color without altering the creamy base.
Swap Half the Peas for Lentils — Creates a different texture and can slightly lower the carb count while keeping the protein high.
Omit Butter, Use All Oil — For a dairy-free version, simply use an extra tablespoon of olive oil during the sauté step.

Common Mistakes to Avoid

Mistake: Skipping the deglaze step. Fix: Always add a bit of liquid and scrape the pot bottom thoroughly after sautéing. This prevents the Instant Pot’s burn warning and captures all the flavor.
Mistake: Adding salt too early, especially with ham. Fix: Wait until after cooking to season. Broths and ham vary widely in saltiness; tasting at the end prevents an overly salty soup.
Mistake: Using a quick pressure release. Fix: Always allow a 15-minute natural release. This gives the peas time to finish breaking down for that signature creamy texture without being mushy.
Mistake: Overfilling the pot. Fix: Never fill past the 2/3 max fill line. The split peas and liquid expand during cooking.
Mistake: Not adjusting the consistency post-cooking. Fix: If your split pea soup is too thick, stir in hot broth or water, 1/4 cup at a time, until it reaches your preferred creaminess.
Mistake: Using old, stale split peas. Fix: Check your peas’ age. Older legumes take much longer to soften and may never achieve the right texture. In my tests, peas over a year old resulted in a gritty soup.

Storing Tips

Fridge: Cool the soup completely, then store in an airtight container. It will keep for 4 to 5 days at 40°F or below. The flavors meld and improve overnight.
Freezer: This soup freezes exceptionally well for up to 3 months. Portion it into freezer-safe bags or containers, leaving 1-inch headspace for expansion. Freezing preserves over 95% of the nutrients and flavor.
Reheat: Thaw overnight in the fridge if frozen. Reheat gently on the stovetop or in the microwave, stirring occasionally and adding a splash of broth or water if it has thickened. The USDA recommends reheating all leftovers to an internal temperature of 165°F.

Storing your Instant Pot split pea soup properly makes it a fantastic make-ahead meal. I always double the recipe to ensure I have ready-to-go lunches or quick dinners for busy nights.

Frequently Asked Questions

How many servings does this Instant Pot Split Pea Soup make?

This recipe yields approximately 6 generous servings of about 1.5 cups each. It’s perfect for feeding a family or for meal prep, providing hearty lunches for the week. The total volume can be adjusted by adding more broth after cooking if you prefer a slightly thinner soup.

Can I make this split pea soup without an Instant Pot?

Yes, you can adapt this for stovetop cooking. Sauté the vegetables in a large pot, then add all ingredients and bring to a boil. Reduce heat, cover, and simmer for 60-90 minutes, stirring occasionally, until the peas are completely soft and broken down. The stovetop method requires more monitoring but achieves a similar creamy texture.

Why is my split pea soup too thin or watery?

A watery soup is usually due to an excess of liquid or not enough cooking time. To fix it, use the “Sauté” function on your Instant Pot and simmer the soup uncovered for 5-10 minutes, stirring frequently, to reduce and thicken. For future batches, you can reduce the initial broth by 1/2 to 1 cup, as the vegetables release their own liquid during cooking.
