This classic version combines 13 different bean varieties—from navy to kidney to black-eyed peas—each contributing unique texture and flavor to create a soup that's rich, satisfying, and packed with plant-based protein.

Ingredients for bob mills 13 bean soup

Thirteen bean varieties, aromatic vegetables, and slow-simmered depth create this vegetarian masterpiece.

The beans form the soul of this recipe, so quality matters. Opt for heirloom or organic dried beans from specialty stores like Penzeys or bulk bins at Whole Foods for superior texture. Each variety contributes unique texture—Great Northerns stay firm, kidney beans add earthiness, while black-eyed peas bring sweetness. Soak them overnight in cold water with a splash of vinegar to prevent bloating, then drain before cooking. For convenience, Trader Joe's carries pre-soaked beans, but fresh dried delivers superior flavor. The mushrooms should be fresh and firm, not slimy or discolored—cremini or baby bella work best for their meaty texture.

No smoked paprika? Liquid smoke at half the amount replicates that campfire depth, though it lacks the subtle complexity. Substitute dried thyme for fresh at a one-third ratio, but fresh delivers brighter flavor. The vegetable broth should be low-sodium—Pacific Foods or Imagine brands excel. For the mushrooms, shiitake adds umami if you're willing to splurge. The celery and carrots can be pre-chopped from the fridge, but fresh is always better. If you're short on time, frozen beans work (no soaking needed), though they lack the rustic texture of dried.

This soup tastes even better the next day as flavors meld. Store in the fridge for up to 5 days, or freeze portions for 6 months—the beans hold their texture remarkably well. For meal prep, double the recipe and freeze half. When reheating, add a splash of broth if it thickens too much. The beans will continue to soften slightly with each reheat, so under-cook slightly if you plan to store leftovers. Serve with crusty bread or cornbread to soak up that rich, smoky broth.

Step-by-step instructions for bob Mills' 13 bean soup

A rich, hearty blend of thirteen bean varieties creates this legendary homestyle stew.

Drain and rinse all soaked beans thoroughly to remove any excess starch. In a large stockpot with an 8-quart capacity, combine the 1.5 cups Great Northern Beans, 1.5 cups Kidney Beans, 1.5 cups Navy Beans, 1.5 cups Black Beans, 1 cup Lima Beans, 1 cup Pinto Beans, 1 cup Chickpeas, 1 cup White Beans, 1 cup Black-Eyed Peas, 1 cup Canellini Beans, and 1 cup Split Peas. Add 8 cups Vegetable Broth and bring to a gentle boil over medium-high heat.

Once boiling, reduce heat to low and maintain a simmer. The beans will need to cook for 1.5-2 hours until they're all fork-tender. I like to stir occasionally to prevent sticking, but don't worry if some beans rise to the surface—they'll settle back down. This long simmering time allows the flavors to meld together beautifully, creating the rich foundation of the soup.

While the beans simmer, heat a large Dutch oven over medium heat. Add 1.5 lbs sliced Mushrooms and cook for 5-6 minutes until they release their moisture and begin to brown. Remove the mushrooms with a slotted spoon and set aside temporarily.

In the same pot, add 4 chopped Celery Stalks, 4 chopped Carrots, and 1 chopped Yellow Onion. Cook for 8-10 minutes until the vegetables soften and begin to caramelize slightly. Add the 6 minced Garlic Cloves and cook for an additional 1 minute until fragrant. This step builds the soup's depth of flavor through the Maillard reaction.

Return the cooked mushrooms to the Dutch oven with the vegetables. Stir in 2 tbsp Smoked Paprika, 1 tbsp Ground Cumin, 2 whole Bay Leaves, 1 tbsp Thyme, 1.5 tbsp Salt, and 1 tbsp freshly cracked Black Peppercorns. Cook for 2-3 minutes until the spices are toasted and aromatic.

Carefully transfer the bean mixture from the stockpot to the Dutch oven using a ladle. Add 1 tbsp Apple Cider Vinegar and stir gently to combine. The acidity from the vinegar brightens the flavors and balances the richness of the beans. Bring the entire mixture to a gentle simmer over medium-low heat.

Let the soup simmer uncovered for 30-45 minutes to allow the flavors to meld together. This final simmering time is crucial for developing the soup's complexity. Taste and adjust seasoning if needed—you might need to add a bit more salt or vinegar to balance the flavors.

The soup should have a thick, hearty consistency with a rich, smoky aroma. If it's too thick, you can add a bit more vegetable broth to reach your desired consistency. The beans should be completely tender, and the vegetables should be soft but still retain some texture. This is where the magic happens—the simple combination of ingredients transforms into something truly special.

Remove the 2 whole Bay Leaves from the soup before serving. Ladle the hot soup into bowls, making sure each serving gets a good variety of beans and vegetables. The soup's richness and depth of flavor will shine through, especially when served with crusty bread or a side of cornbread.

This soup tastes even better the next day as the flavors continue to develop. Store any leftovers in an airtight container in the refrigerator for up to 5 days. The combination of thirteen different bean varieties creates a symphony of textures and flavors that's both comforting and satisfying. Each spoonful delivers a little bit of everything, making this one of the most rewarding soups you'll ever make.

Troubleshooting this dish

Beans Too Hard?

If your beans aren't tender after 2 hours of simmering, they likely need more time or higher heat. Increase the temperature to medium-high for 15-20 minutes, then return to a gentle simmer. Some beans like Great Northerns and kidney beans can be stubborn—check them individually with a fork.

For extra help, add ½ tsp baking soda to the pot (it breaks down pectin), but don't overdo it—too much makes beans mushy. 🌱

Broth Too Thin?

A watery soup often means the beans released too much starch. Reduce the heat to low and let it simmer uncovered for 15-20 minutes to thicken naturally. If it's still too thin, mash ¼ cup of the beans with a potato masher to thicken the broth.

For a smoother texture, blend ½ cup of the soup and stir it back in. Avoid adding flour or cornstarch—it can make the soup taste artificial. ✨

Mushrooms Too Slimy?

Slimy mushrooms mean they're overcooked or weren't fresh to begin with. Start with fresh cremini or baby bella mushrooms and cook them over medium heat for just 5-6 minutes until golden. If they still release too much moisture, pat them dry with a paper towel before cooking.

For extra flavor, sauté them in 1 tbsp olive oil first to help them brown properly. 🍄

Flavor Too Mild?

If your soup lacks depth, boost the umami with 1 tbsp soy sauce or ½ tsp miso paste during the final simmer. For smokiness, add ½ tsp liquid smoke or toast ½ cup of the beans in a dry pan before adding them to the pot.

A splash of apple cider vinegar (up to 1 tbsp) brightens the flavors, while a pinch of cayenne pepper adds subtle heat. Taste as you go—adjust gradually! 🌶️

Vegetables Still Crunchy?

If carrots or celery remain undercooked, they likely need more time. Simmer uncovered for an additional 10-15 minutes on low heat. For faster results, chop vegetables slightly smaller next time.

If they're still tough, add ½ cup extra broth and simmer for 5 more minutes. Overcooked veggies turn mushy, so aim for tender-but-firm texture. 🥕

Soup Too Salty?

If the soup tastes overly salty, add ½ cup unsalted vegetable broth or 1 cup water to dilute the flavor. For a natural fix, stir in 1 tbsp apple cider vinegar or 1 tbsp lemon juice to balance the saltiness.

Avoid adding more beans—they’ll absorb the broth and concentrate the salt. Taste frequently to avoid overshooting! 💧
