Ingredients for insta pot split pea soup

Master the smoky herb depth of this vegetarian split pea soup with just twelve essential ingredients.

The split peas form the heart of this recipe, so choose high-quality dried peas from a reputable brand like Bob’s Red Mill or Anthony’s Goods. Freshly ground black peppercorns and smoked paprika from Penzeys Spices elevate the smoky depth—never skip the browning step with olive oil to develop those rich aromatics. For the vegetable broth, low-sodium options from Pacific Foods work best, but homemade is ideal. The carrots and celery should be fresh, crisp pieces—avoid any with soft spots or wilting. Fresh thyme and parsley add brightness, so grab them from the grocery store’s refrigerated section where they’re kept at peak freshness.

No smoked paprika? Substitute liquid smoke at 1/4 teaspoon—use sparingly, as it’s potent. Fresh thyme unavailable? Dried thyme at one-third the amount works, but toast it lightly in a dry pan first to enhance flavor. The vegetable broth can be swapped for water plus 1 teaspoon vegetable bouillon in a pinch. For extra richness, add 1/4 cup coconut milk at the end, though it won’t be as creamy. The split peas can be substituted with canned peas for a quicker version, though texture will differ. Always rinse canned peas thoroughly to remove excess sodium.

This soup develops even better the next day, so make a double batch for meal prep. Store in airtight containers in the fridge for up to 5 days or freeze for 3 months—the flavors continue melding during storage. For reheating, use the sauté function on your Instant Pot with 1/4 cup water to restore creaminess. Garnish with fresh parsley just before serving to maintain vibrant color. The natural release method is critical—never skip the 10-minute release to achieve that velvety texture without overcooking the peas.

Step-by-step instructions for Insta Pot split pea soup

This method delivers restaurant-quality depth using only your pressure cooker.

Set your Insta Pot to the “Sauté” function and add the 1 tablespoon extra-virgin olive oil. Allow it to heat for 30 seconds until shimmering. Add the 1 whole diced yellow onion, 2 medium diced carrots, and 2 whole diced celery stalks (with leaves). Cook for 5 minutes until the vegetables soften and the onion becomes translucent.

Here’s the thing—don’t rush this step. The vegetables should release their natural juices and begin to caramelize slightly at the edges. Add the 3 minced garlic cloves and cook for an additional 30 seconds until fragrant. This foundational layer carries all the soup’s flavor, so take your time. If the vegetables stick, add 1 tablespoon vegetable broth to deglaze and scrape up any browned bits from the bottom of the pot.

Stir in the 1 tablespoon smoked paprika, 2 whole bay leaves, and 0.5 teaspoon finely chopped fresh thyme. Cook for 30 seconds to toast the spices and release their aromatic oils. This is where the smoky depth comes from—don’t skip this step. Add the 1.5 cups rinsed dried yellow split peas, 4 cups vegetable broth, 1.5 teaspoons salt, and 0.5 teaspoon freshly cracked black peppercorns. Give everything a thorough stir to combine.

Real talk: The split peas will expand significantly as they cook, so make sure they’re fully submerged in the broth now. If they’re not covered, add a splash of water to ensure even cooking. The broth should be just below the maximum fill line on your Insta Pot to prevent potential overflow during pressure cooking.

Secure the lid on your Insta Pot and set it to the “Pressure Cook” function for 15 minutes. Once the cooking cycle completes, allow the pressure to release naturally for 10 minutes before quick-releasing any remaining pressure. This gradual release prevents the peas from becoming mushy while ensuring they’re tender and fully cooked.

Your oven might run hot, so start checking at the 20-minute mark. The split peas should be fork-tender with just a slight bite remaining—this texture is ideal for soup. If you prefer completely soft peas, cook for an additional 3-5 minutes on high pressure. The natural release is critical here; forcing a quick release will result in overcooked, grainy peas.

Remove the 2 whole bay leaves and discard them. Stir in the 0.25 cup chopped fresh parsley and adjust the seasoning if needed. Taste and add more salt or pepper if the soup needs it. The parsley adds a bright finish that cuts through the richness of the split peas and balances the smoky notes from the paprika.

Serve the split pea soup immediately while still hot. The natural release ensures the peas hold their shape while absorbing all the flavorful broth. Each spoonful should deliver creamy texture, smoky depth, and a perfect balance of sweet vegetables. For a heartier meal, serve with crusty bread or a side of roasted vegetables. The soup will thicken slightly as it cools, so don’t worry if it appears a bit loose when served.

Dietary considerations for this dish

Vegetarian-Friendly Base

This recipe is naturally vegetarian with no meat, dairy, or eggs—perfect for plant-based diets. The split peas provide 15 grams of protein per serving, making it a hearty protein source without relying on animal products.

The broth is made from vegetable stock instead of meat-based options, ensuring it aligns with vegetarian principles while delivering rich, savory depth. 🌱

Gluten-Free Adaptations

All ingredients in this recipe are inherently gluten-free, but always double-check labels on your vegetable broth and smoked paprika to avoid cross-contamination. I recommend Pacific Foods low-sodium broth, which is certified gluten-free.

For extra safety, use a dedicated gluten-free kitchen area if you also prepare gluten-containing foods. The split peas and other vegetables are naturally free of gluten, so no substitutions are needed here.

Low-Sodium Options

To keep this soup low-sodium, use low-sodium vegetable broth (like Pacific Foods) and reduce the added salt to 1 teaspoon instead of 1.5 teaspoons. The natural flavors of the split peas and herbs will still shine, and you’ll avoid excess sodium without sacrificing taste.

If you’re avoiding salt entirely, boost umami with an extra ½ teaspoon of smoked paprika or a splash of soy sauce (ensure it’s gluten-free if needed).

Vegan Considerations

This recipe is already vegan-friendly, but if you want to enhance its creaminess, stir in ¼ cup coconut milk or cashew cream at the end for a richer texture. The split peas naturally thicken the soup, so no additional thickeners are necessary.

For extra depth, add 1 teaspoon nutritional yeast—it adds a cheesy, umami flavor without dairy. Always check labels on spices and broth to confirm they’re vegan-certified.

Allergen Awareness

This soup contains no common allergens like nuts, dairy, or eggs, making it safe for most dietary restrictions. However, if you’re sensitive to FODMAPs, reduce the onion and garlic to 1 teaspoon each to minimize digestive discomfort.

For those with celiac disease, ensure your smoked paprika and broth are certified gluten-free. The recipe’s simplicity means fewer potential allergen sources, but it’s always wise to review ingredient labels.

Meal Prep for Dietary Needs

This soup stores beautifully for meal prep, making it ideal for vegetarian, gluten-free, or low-sodium diets. Store in airtight containers in the fridge for up to 5 days or freeze for 3 months.

When reheating, use the sauté function on your Instant Pot with ¼ cup water to restore creaminess. For vegan meal prep, portion into individual containers and freeze with a splash of broth to prevent drying out.

The natural release method ensures flavors develop even during storage, keeping every spoonful delicious. ✨
