The beans are the soul of this soup, so pick a mix you love. I grab mine in bulk bins at Whole Foods or Trader Joe's—they're cheaper and fresher than canned. If you're using dried, make sure they're organic or at least non-GMO for better flavor. The canned beans work too, but they lack that earthy depth. Pro tip: Soak dried beans overnight for even better texture, but the Instant Pot handles them just fine unsoaked—just add 10 minutes to the cook time.
No smoked paprika? Regular paprika plus a pinch of liquid smoke works in a pinch. Fresh parsley wilting? Dried parsley at one-quarter the amount gets you close. Short on broth? Water plus a bouillon cube does the trick, but low-sodium vegetable broth is ideal. The tomato paste can be skipped if you're not a fan, but it adds that umami richness that ties everything together. For extra depth, toast the cumin and spices in the pot for 30 seconds before adding liquids—game-changer for flavor.
This soup tastes even better the next day as flavors meld together. Store in an airtight container in the fridge for up to 5 days or freeze portions for 3 months. I double the batch and freeze half—perfect for lazy weeknights. To reheat, just add a splash of water or broth and warm on high pressure for 5 minutes. Garnish with fresh parsley right before serving to keep it vibrant and fresh-tasting.

Step-by-step instructions for Instant Pot 15 bean soup
Transform pantry staples into a hearty, flavor-packed soup in minutes—this method guarantees tender beans and deep, aromatic flavors.
Sauté the Aromatic Base
Set your Instant Pot to the "Sauté" function and add the 2 tablespoons olive oil. Once shimmering, add the 1 whole onion, 2 whole carrots, and 2 whole celery stalks—all chopped into ½-inch pieces. Cook for 5-6 minutes until the vegetables soften and the onion becomes translucent.
Add the 4 cloves garlic cloves (minced) and cook for another 30 seconds until fragrant. Here's the thing—don't let the garlic burn, or you'll taste bitter notes instead of sweet. Stir constantly and watch closely during this final minute. The base should smell like a warm, spiced hug—this is the foundation of your soup's flavor.
Add Spices and Tomato Paste
Reduce the heat to "Low" and stir in the 1 tablespoon ground cumin, 1 tablespoon smoked paprika, and 1.5 teaspoons salt. Let the spices toast for 30 seconds—you'll see them sizzle and release their aromatic oils. This step is crucial for building depth of flavor.
Next, add the ¼ cup tomato paste and stir vigorously for 1 minute to fully incorporate. The paste will darken slightly as it melts into the vegetable mixture. This creates a rich, slightly sweet base that balances the earthy beans. If you're using a squeeze tube, press it directly into the pot for even distribution.
Combine All Ingredients
Add all the rinsed beans: 1 cup dried black beans, 0.5 cup dried kidney beans, 0.5 cup dried pinto beans, 0.5 cup dried navy beans, 0.5 cup dried great northern beans, and 0.25 cup dried chickpeas. Stir to coat them evenly with the spiced vegetable mixture.
Pour in the 4 cups canned vegetable broth and add the 2 whole bay leaves. Give everything a final stir, making sure the beans are fully submerged. The broth should just cover the beans—if it looks too thin, add a splash of water. The beans will expand significantly as they cook, so don't worry if they don't look completely submerged now.
Pressure Cook to Perfection
Secure the lid and set the Instant Pot to "High Pressure" for 25 minutes. This is where the magic happens—the beans will transform from hard, dry legumes into tender, creamy morsels. Real talk: don't skip the pressure cooking step. Stovetop methods take hours, but this delivers restaurant-quality results in a fraction of the time.
Once the cooking cycle completes, let the pressure release naturally for 10 minutes before quick-releasing any remaining pressure. This gradual release prevents the beans from becoming mushy. When you open the lid, you'll be greeted with a pot of thick, hearty soup that smells even more incredible than it did before cooking.
Finish and Serve
Remove the 2 whole bay leaves and stir in the 0.25 cup chopped fresh parsley and 0.5 teaspoon black pepper. Taste and adjust the seasoning—you might need a pinch more salt to balance the flavors now that the beans have absorbed some of the broth.
For serving, ladle the soup into bowls and garnish with additional parsley if desired. Each spoonful should deliver a perfect balance of creamy beans, smoky spices, and fresh herbs. This soup tastes even better the next day as the flavors continue to develop—make extra and enjoy it for lunch or dinner throughout the week.
Pro Tips For Making 15 Bean Soup Recipe Vegetarian Instant Pot
- SOAK BEANS OVERNIGHT: I learned this the hard way—rushing overnight soaks with dried beans in the Instant Pot leads to gummy texture. Use 6 cups water per pound of beans, cover, and let sit 12+ hours (or quick-soak: boil 2 minutes, then 1 hour off heat). Navy beans need the longest; don’t skip this for kidney beans either.
- SORT BEANS BY SIZE: Uneven cooking ruins the texture. Split your dried beans into two groups: pintos/blacks (smaller) and navies/great northerns (larger). Cook the smaller beans first for 10 minutes, then add the rest—this guarantees all beans finish tender at the same time.
- PRESSURE-COOK HALF FIRST: Don’t dump all 15 beans in at once. Start with 8 cups mixed beans (about 1 lb) and 4 cups broth, cook on high for 12 minutes. Then add remaining beans and broth for another 8 minutes. This prevents overcooking the first batch while waiting for the second.
- SAVE TIME WITH FROZEN SOUP BASE: I was skeptical until I tried it—use 1 cup frozen vegetable broth (not bouillon) instead of homemade. It adds depth without salt overload and cuts prep by 10 minutes. Just toss it in with the beans during the pressure cook.
Essential equipment for this dish
Instant Pot Essentials
The Instant Pot is your secret weapon for this recipe—no fancy gadgets required. You’ll need a 6-quart model (like the Instant Pot Duo Evo Plus) to handle the bean volume comfortably. The steam release valve is critical: always use the natural release setting for the first 10 minutes to avoid mushy beans. Trust me, this small detail makes all the difference in texture. 🌡️
Bean Prep Tools
Rinsing beans thoroughly removes debris and reduces cooking time. I use a fine-mesh colander (like the OXO Good Grips) to clean them before adding to the pot. For dried beans, soaking overnight in a bowl with plenty of water (at least 8 cups) speeds up cooking, but the Instant Pot handles them just fine unsoaked—just add 10 extra minutes to the cook time. A wooden spoon works great for stirring during the sauté step.
Spice Toasting Tip
Toasting spices in the pot unlocks their full flavor. Use a heat-resistant spatula (like the OXO Good Grips) to stir constantly while the cumin and paprika toast. A small kitchen timer (set for 30 seconds) prevents burning. Pro tip: Toast spices in a dry pot first if you’re worried about sticking—just add them to the pot after sautéing the veggies. This step is non-negotiable for depth of flavor. 🌶️
Broth and Liquid Control
Measure broth precisely—4 cups is ideal, but use a liquid measuring cup for accuracy. If your soup looks too thick after cooking, add ½ cup water and cook for an additional 3 minutes on high pressure. A ladle helps transfer the soup to bowls without spills. For serving, I love using preheated bowls to keep the soup hot longer—just pop them in the microwave for 10 seconds before ladling.
Garnish and Serving
Fresh parsley brightens the dish, but a microplane works better than scissors for fine, even chopping. For extra crunch, toast 1 cup pita chips in the oven at 350°F for 5 minutes—they add texture without overpowering the soup. A slotted spoon makes removing bay leaves effortless. Serve with crusty bread or a simple arugula salad for balance. 🥗

Frequently asked questions
Can I use canned beans instead of dried?
Yes! You can absolutely substitute canned beans for dried. Use 2 (15-ounce) cans of each bean type (black, kidney, pinto, navy, great northern, and chickpeas) instead of the dried versions. Drain and rinse them well before adding to the pot. The soup will be ready even faster—just reduce the cooking time to 10 minutes on high pressure after adding all ingredients. The texture will be slightly softer but still delicious.
Why does my soup look too thick after cooking?
This happens because beans absorb liquid as they cook. To fix it, add ½ cup water or broth and cook for an additional 3 minutes on high pressure. For prevention, start with 4½ cups liquid instead of 4 cups. The soup should have a creamy consistency but still be easy to ladle. If it's still too thick, stir in a splash of warm water or broth while serving.
Can I make this soup gluten-free?
This recipe is naturally gluten-free as long as you use gluten-free vegetable broth and check that your spices (like smoked paprika) are certified gluten-free. The beans, vegetables, and other ingredients are all gluten-free by default. Just avoid adding bread or croutons as toppings if you're strictly gluten-free. The soup's flavor remains rich and satisfying without any gluten-containing ingredients.
How do I adjust the spice level?
For milder flavor, reduce the smoked paprika to ½ tablespoon and omit the cayenne if using. For extra heat, add ¼ teaspoon cayenne pepper or a pinch of red pepper flakes when toasting the spices. You can also adjust the salt to taste after cooking—beans often absorb some of the initial seasoning. Start with the recipe as written and tweak to your preference.
Can I freeze this soup for later?
Yes, this soup freezes beautifully! Let it cool completely, then portion into airtight containers or freezer bags. It keeps for up to 3 months in the freezer. To reheat, thaw overnight in the fridge, then warm on the stovetop or in the Instant Pot on high pressure for 5 minutes. Stir in a splash of water or broth if it thickens too much during reheating. The flavors actually deepen after freezing!
