Soups & Stews
This vegetarian 15 bean soup recipe transforms pantry staples into a hearty, protein-rich meal in just 30 minutes using your Instant Pot. The secret lies in layering flavors through slow cooking—where dried beans soften perfectly, vegetables develop depth, and spices meld into a comforting, smoky-sweet harmony. I developed this version after realizing how often dried beans get overlooked in quick meals, yet deliver restaurant-quality satisfaction without the wait.

The Instant Pot handles the heavy lifting—breaking down tough beans while keeping vegetables tender-crisp. A well-balanced blend of spices (smoked paprika, bay leaf, and thyme) creates warmth without overpowering the natural earthiness of the beans and broth.
What you’ll end up with is a rich, velvety soup with pockets of texture from al dente carrots, celery, and onions—each bite packed with plant-based protein and satisfying heartiness. The aroma alone will transform your kitchen into a cozy gathering spot, and the leftovers reheat beautifully, making this perfect for meal prep or feeding a crowd.
Serve it with crusty bread to soak up every last drop or pair with a crisp white wine for a complete meal. The versatility of this recipe means you can customize it with your favorite beans or vegetables—just keep the cooking time and liquid ratio in mind. Let’s get started on this pantry-friendly masterpiece.

The beans are the heart of this recipe—dried varieties work best since they soften perfectly in the Instant Pot without pre-soaking. Costco or bulk bins often have the best prices for mixed beans, but any grocery store carries the basics. Look for beans with a vibrant color and no signs of moisture or pests. The tomato paste from Trader Joe's squeeze tubes is perfect here—no waste, and it keeps for months. Fresh thyme is ideal, but dried thyme works at one-third the amount if that's what you've got. The smoked paprika adds that restaurant-quality depth, so don't skip it—Penzeys or the bulk section at Whole Foods have great options.
No smoked paprika? Substitute 1/2 tsp liquid smoke for a similar effect, though the flavor won't be identical. Running low on thyme? Fresh parsley or oregano can stretch it out. The apple cider vinegar might seem odd, but it brightens the whole dish—substitute lemon juice if that's what you've got. For the broth, low-sodium is key—you'll be adding salt later, and you don't want to overdo it. The carrots, celery, and onions form the flavor base, so don't skip them. If you're in a hurry, pre-chopped frozen veggies work in a pinch, but fresh gives the best texture. The garlic can be minced ahead of time and stored in the fridge for up to 5 days.
This soup tastes even better the next day as flavors meld—portion into containers for easy lunches. Keeps in the fridge for 5-6 days or freeze for up to 3 months. The beans thicken as they cool, so add a splash of broth when reheating. Double the batch if you're feeding a crowd—it's perfect for potlucks. Store dried beans in a cool, dark place for up to 1 year, and fresh herbs in damp paper towels in the fridge for up to 5 days. The tomato paste and spices can sit in your pantry for years, making this a true pantry-to-pot recipe.

Step-by-step instructions for vegetarian 15 bean soup
Transform pantry staples into a rich, hearty soup with minimal effort.
Prepare and Combine All Beans
In a large bowl, combine all 1 cup dried navy beans, 1 cup dried kidney beans, 1 cup dried black beans, 1 cup dried pinto beans, 0.5 cup dried chickpeas, 0.5 cup dried white beans, and 0.5 cup dried lentils. Rinse them thoroughly under cold water to remove any debris, then drain well. This thorough rinsing prevents cloudiness in your finished soup.
Transfer the rinsed beans to your Instant Pot and add 6 cups vegetable broth. Stir gently to ensure all beans are submerged. The broth should cover the beans by about 1 inch—this ensures even cooking and prevents them from sticking to the bottom. I like to give the pot a quick shake to distribute the beans evenly before proceeding.
Sauté Aromatics and Spices
Set your Instant Pot to the "Sauté" function and add 1 whole yellow onion (diced), 3 whole carrots (cut into 1-inch chunks), and 3 whole celery stalks (cut into 1-inch pieces). Cook for 5 minutes, stirring occasionally, until the vegetables begin to soften and the onion becomes translucent.
Add 4 cloves minced garlic, 1 tbsp smoked paprika, and 1 tsp ground cumin. Stir for 1 minute until the spices are fragrant and the garlic releases its aroma. This step builds the foundational flavors that will infuse the entire soup. If you're using fresh thyme, add 1 tbsp thyme leaves now along with the 2 whole bay leaves—they'll steep beautifully during cooking.
Pressure Cook Until Tender
Secure the lid on your Instant Pot and set the valve to "Sealing." Cook on High Pressure for 25 minutes. This time ensures all the beans and vegetables become fork-tender while maintaining their texture. The pressure cooker does most of the work here, transforming tough dried beans into creamy, flavorful components.
Once cooking is complete, allow the pressure to release naturally for 10 minutes, then quick-release any remaining pressure. This gradual release prevents beans from becoming mushy. Open the lid carefully—you'll be greeted by an aromatic blend of spices and vegetables that signals the soup is nearly ready for finishing touches.
Finish with Acid and Seasoning
Stir in 2 tbsp tomato paste and 1 tbsp apple cider vinegar. These ingredients brighten the soup and balance the earthy flavors of the beans. The tomato paste adds depth while the vinegar cuts through any heaviness. Taste and adjust seasoning with 1.5 tsp salt and 0.5 tsp black peppercorns—you might need less salt if your broth was already seasoned.
Remove and discard the bay leaves before serving. These were just flavor carriers during cooking. Give the soup one final stir and let it sit for 5 minutes to allow flavors to meld. The result should be a rich, hearty soup with a perfect balance of smoky, earthy, and slightly tangy notes that make every spoonful satisfying.
Pro Tips For Making 15 Bean Soup Recipe Vegetarian Instant Pot
- SOAK NAVY BEANS ONLY: I learned this the hard way—navy beans are the only ones that need soaking for the Instant Pot. Skip it for kidney, black, or pinto beans, but give the navy beans 8 hours (or overnight) in cold water. They’ll soften faster and avoid that gummy texture that ruins everything.
- USE 2 CUPS LIQUID PER BEAN: The Instant Pot’s pressure cooker is forgiving, but don’t skimp on broth or water. Aim for 2 cups of liquid per 1 cup of dried beans—this recipe has five types, so start with 10 cups. Too little liquid = mushy beans; too much = sad, watery soup. (Yes, even if the pot feels half-empty.)
- ADD CHICKPEAS LAST: Chickpeas take longer to soften than other beans, and starting them together often leaves them rock-hard. Toss them in during the last 10 minutes of cooking—this guarantees they’ll be tender without falling apart. (Pro move: Rinse them first to cut down on cooking time.)
- SALT AFTER PRESSURE RELEASE: Salting early turns beans tough and mealy. Wait until the pot’s naturally released pressure, then add salt with the tomatoes and herbs. The beans will absorb flavor better, and you won’t end up with a bland, overcooked mess. (I know, I know—patience isn’t your strong suit either.)
Essential equipment for this recipe
Instant Pot Essentials
Your Instant Pot is the star of this recipe, but a few key accessories make all the difference. First, invest in a good-quality trivet—I use the OXO Good Grips—to keep your pot from scratching and ensure even heat distribution. A heavy-duty silicone spatula (like OXO’s 12-inch version) helps scrape up all the flavorful bits from the bottom. 🌡️
For measuring precision, a digital kitchen scale (I love the OXO Good Grips) is a game-changer, especially when balancing broth-to-bean ratios. A fine-mesh strainer comes in handy for rinsing beans and draining excess liquid, while a microplane ensures your garlic and spices are finely minced for even distribution.
Bean Prep Tools
Prepping dried beans efficiently is key. A large mixing bowl (like the Pyrex 8-cup version) lets you rinse all the beans at once, and a colander with sturdy handles makes draining effortless. For speed, I use a handheld electric mixer (like the KitchenAid KSM150PSER) on low to agitate the beans in the broth—this cuts cooking time by ensuring even saturation.
A sharp chef’s knife and cutting board (I prefer Shun Premier for durability) are essential for dicing onions, carrots, and celery uniformly. A vegetable peeler helps remove carrot skins quickly, and a garlic press saves time when mincing cloves. These tools ensure your veggies cook evenly and release their flavors properly.
Pressure Cooking Safety
Safety first! A heat-resistant glove (like Oven Mitts by OXO) protects your hands when handling the hot Instant Pot lid. Always use a lid lock (included with most Instant Pots) to secure the valve during cooking. A timer (your phone or a kitchen timer) ensures you don’t overcook the beans—25 minutes is perfect for tender but not mushy texture.
For natural pressure release, I recommend a small bowl to catch any steam that escapes when opening the lid. A ladle (like OXO’s Good Grips) helps portion the soup evenly into bowls, and a fine-mesh sieve strains out bay leaves before serving. These tools keep your cooking process smooth and safe.
Optional Upgrades
If you love garnishes, a microplane for fresh herbs (parsley, thyme) or a small mortar and pestle (like Kuhn Rikon) crushes spices like cumin for deeper flavor. For serving, a soup ladle (like Le Creuset’s stainless steel) elevates presentation. A slow cooker liner (if your Instant Pot has one) makes cleanup a breeze—just toss it in the trash after cooking.
For meal prep, glass storage containers (like Pyrex 8-cup bowls) keep leftovers fresh for up to 5 days, while freezer-safe bags extend shelf life to 3 months. These upgrades turn your Instant Pot into a multi-purpose kitchen workhorse. 💫

Frequently asked questions
Do I need to soak the beans overnight for this Instant Pot recipe?
No soaking required! The Instant Pot's high-pressure cooking breaks down dried beans perfectly without pre-soaking. Just rinse them thoroughly before adding to the pot. This saves you 8+ hours of wait time while still delivering tender, flavorful beans.
Can I use canned beans instead of dried for faster prep?
Use 2 (15 oz) cans of each bean type (navy, kidney, black, etc.) instead of dried. Reduce cooking time to 10 minutes on High Pressure after sautéing. Just drain and rinse the cans first to remove excess sodium. The texture will be slightly softer but still delicious.
Why does my soup turn out too thick or too thin?
Thick? Add ½ cup broth and cook 5 more minutes. Thin? Simmer uncovered for 3-5 minutes to reduce. The key is starting with 6 cups broth—this recipe's magic ratio. If using canned beans, they release more liquid, which may require additional cooking time to thicken.
How can I make this soup spicier without adding heat?
Boost flavor with 1 extra tbsp smoked paprika or ½ tsp cayenne. For depth without heat, add 1 tsp liquid smoke or 1 extra bay leaf. The apple cider vinegar also brightens flavors—try 2 tbsp for extra tang. Always taste as you go!
Can I freeze this soup for meal prep?
Yes! Cool completely, then portion into freezer-safe containers with 1-inch headspace. Freeze for up to 3 months**. Thaw overnight in the fridge—never microwave directly from frozen. Add a splash of broth when reheating to restore texture.
