The dry bean mix is key—Hurst’s 15 Bean Soup (found at Walmart or Target) is a reliable choice. Ensure the mix is free of non-vegan seasoning packets, as some brands include animal-derived additives. For the vegetable broth, Imagine or Pacific Foods offer robust, organic options. Fresh vegetables should be firm and vibrant—no wilting celery or soft carrots. The onion, carrot, and celery trio forms the flavor foundation.

Need to swap the onion? Shallots or leeks work beautifully. No celery? Fennel bulb at half the amount adds a nice anise note. For a smokier profile, liquid smoke at 1/4 tsp can amplify the paprika. Canned tomatoes can be crushed by hand for a rustic texture. If using fresh tomatoes, add 1.5 cups diced and reduce broth by 1 cup.

Store dry beans in a cool, dark place for up to 1 year. Once cooked, the dish keeps in the fridge for 5 days or can be frozen in portions for 3 months. The flavors deepen overnight, making leftovers even more delicious.

Step-by-Step Instructions for 15 Bean Instant Pot

This method ensures perfectly tender beans and a rich, flavorful broth with minimal hands-on time.

Step 1: Prepare the Aromatics and Spices

Begin by finely dicing the yellow onion, carrots, and celery stalks into uniform pieces for even cooking. Mince the 4 cloves garlic cloves to release their full flavor. These vegetables form the aromatic foundation of your dish.

In a small bowl, combine the 1 tsp dried thyme, 1 tsp smoked paprika, 1 tsp ground cumin, 1 tsp salt, and 0.5 tsp black pepper. This spice blend will infuse the beans with depth and complexity.

Step 2: Sauté the Vegetables in the Instant Pot

Set the Instant Pot to the sauté function and add the 2 tbsp olive oil. Once the oil shimmers, add the diced yellow onion, carrots, and celery stalks. Cook for 4-5 minutes, stirring occasionally, until the vegetables soften and the onion becomes translucent.

Stir in the minced garlic cloves and cook for 30 seconds until fragrant. Immediately add the 2 tbsp tomato paste and stir to coat the vegetables, allowing it to cook for 1-2 minutes to deepen its flavor. This step builds a rich base for your soup.

Step 3: Add Remaining Ingredients and Pressure Cook

Rinse the 1 lb 15 bean soup mix under cold water to remove any debris, then drain well. Add the beans to the Instant Pot along with the 1 can canned diced tomatoes (with juices), 8 cups vegetable broth, and the prepared spice blend. Stir to combine, ensuring all ingredients are submerged in the liquid.

Add the 2 pieces dried bay leaves to the pot. Secure the lid, set the valve to sealing, and cook on high pressure for 30 minutes. The Instant Pot will take 10-15 minutes to come to pressure before the cooking time begins.

Step 4: Release Pressure and Finish

Once the cooking time is complete, allow the pressure to release naturally for 10 minutes, then quick-release any remaining pressure. Remove the lid carefully, tilting it away from you to avoid steam burns.

Discard the dried bay leaves and stir the soup. Taste and adjust seasoning if needed, though the flavors will continue to meld as it sits. The beans should be tender but not mushy, and the broth should be rich and aromatic.

Let the soup rest for 5-10 minutes before serving to allow the flavors to fully develop. This dish is hearty enough to serve as a main course for 4.

Dietary Considerations for This Dish

Naturally Vegan

This creation is inherently plant-based, packed with 15 varieties of beans delivering complete protein. Each serving offers about 15g of fiber and 12g of protein from beans alone. Perfect for vegan meal prep.

Gluten-Free Friendly

All ingredients are naturally gluten-free, but verify your 15 bean mix—some brands process in facilities with wheat. Hurst’s and Goya typically label their mixes clearly. Always check packaging to be safe.

Low-Sodium Control

Using low-sodium vegetable broth lets you manage salt content. I recommend Imagine or Pacific Foods brands. You can always add 1 tsp salt at the end if needed, but most find it unnecessary.

Allergen Notes

This dish is free from dairy, eggs, and nuts. However, some bean mixes include soy—check the label if allergies are a concern. The recipe contains no added allergens beyond what’s in your chosen mix.

Nut-Free Adaptation

While naturally nut-free, cross-contamination can occur in bean processing. For severe allergies, seek certified nut-free facilities. Eden Organic beans are processed in dedicated allergen-free plants. 💪

Diabetic Considerations

The high fiber content helps stabilize blood sugar. One serving contains approximately 30g net carbs. Pair with a side of greens for a balanced meal that won’t spike glucose levels.
