Ingredients for bob's red mill 15 bean soup

Fifteen beans, one pot, endless comfort—this is your pantry transformed into pure heartiness.

The beans are the star, so Bob's Red Mill 15 Bean Mix is non-negotiable here. Grab the bag from Whole Foods or Amazon—it's a mix of kidney, black, pinto, and more, giving you that perfect texture medley. If you can't find it, substitute with 1 cup each of dried kidney, black, and pinto beans. The onion, celery, and carrots form the holy trinity—freshly diced for that aromatic base. Garlic? Four cloves is your sweet spot. Pro tip: Soak the beans overnight to cut cooking time by half.

No fire-roasted tomatoes? Regular diced tomatoes work fine. Short on thyme? Dried oregano at double the amount gets you close. The tomato paste is key for thickness—Trader Joe's has the best squeeze tubes for this. Need to skip smoked paprika? Regular paprika plus a pinch of liquid smoke mimics it. The broth? Low-sodium so you control the salt. And yes, you can use vegetable bouillon cubes in a pinch—just dissolve them first.

This soup tastes even better the next day—make a double batch. Store in airtight containers for 5 days or freeze for 6 months. The beans soften more overnight, creating that creamy texture. For meal prep, freeze in 1-cup portions—perfect for lunches. Reheat gently on the stove with a splash of water to restore creaminess. Leftovers reheat beautifully, so don't hold back on making extra.

Step-by-step instructions for bob's Red Mill 15 bean soup

This hearty soup comes together with simple steps and delivers maximum flavor and protein.

Heat the 0.25 cup extra-virgin olive oil in a large Dutch oven over medium heat. Add the diced yellow onion, diced celery stalk, and diced carrots. Cook for 8-10 minutes, stirring occasionally, until the vegetables soften and begin to caramelize slightly—that's when you'll notice their natural sweetness intensifying.

Add the minced garlic cloves and cook for another 1 minute until fragrant. This foundational step builds the soup's flavor base, so don't rush it. The vegetables should be tender but not mushy, and the garlic should smell deeply aromatic without burning.

Stir in the canned diced tomatoes (with juices), 0.25 cup tomato paste, 1 tsp dried thyme, 1 tsp dried oregano, 1 tsp smoked paprika, 1.5 tsp salt, and 0.5 tsp black pepper. Cook for 3-4 minutes until the mixture thickens slightly and the tomato flavors meld together.

Add the 2 whole bay leaves and 6 cups vegetable broth, stirring well to combine. The broth should just cover the vegetables. Bring the mixture to a gentle boil, then reduce heat to medium-low and let it simmer for 10 minutes to let all the spices infuse.

Add the 2 cups Bob's Red Mill 15 Bean Mix to the simmering broth. Stir gently to distribute the beans evenly. The recipe calls for dried beans, which need proper soaking and cooking time—this blend contains a variety of beans that will create a rich, textured soup.

Bring the soup back to a gentle boil, then reduce heat to low and cover partially. Let it simmer for 45-60 minutes, stirring occasionally to prevent sticking. The beans are done when they're tender but still hold their shape—you'll know they're ready when a bean easily pierces with a fork and the soup has thickened noticeably.

Remove the bay leaves and taste the soup. Adjust seasoning with additional salt or black pepper if needed. The soup should be well-seasoned with a balance of tomato, bean, and herb flavors. If it's too thick, add ½ cup water or broth to reach your desired consistency.

Let the soup sit off the heat for 5-10 minutes before serving. This resting time allows the flavors to meld completely and the beans to absorb any remaining liquid. Serve warm with crusty bread or over rice for a complete meal.

Creative variations of bob's red mill 15 bean soup

Spicy Southwest Twist

Transform your soup into a fiesta of flavors by adding 1 tbsp chili powder and ½ tsp ground cumin when sautéing the aromatics. For extra heat, stir in 1 diced jalapeño pepper (seeds removed for mild heat) with the tomatoes.

Top each serving with ¼ cup shredded Monterey Jack cheese and 2 tbsp chopped cilantro right before serving. This variation turns your soup into a hearty, smoky, and slightly spicy Mexican-inspired dish. 🌶️

Creamy Coconut Version

Swap out the vegetable broth for 6 cups coconut milk (full-fat for creaminess) and reduce the salt to 1 tsp. Add 1 tsp ground ginger and ½ tsp turmeric during the sautéing step for warmth.

After simmering the beans, stir in ½ cup unsweetened coconut milk to thicken the soup naturally. Garnish with toasted coconut flakes and fresh mint leaves for a tropical twist that’s rich and satisfying. 🥥

Italian-Inspired White Bean Upgrade

Replace 1 cup of the Bob’s Red Mill 15 Bean Mix with 1 cup cannellini beans (drained and rinsed) for a Mediterranean flair. Add ½ cup diced sun-dried tomatoes (oil packed) and 2 tbsp capers when sautéing the vegetables.

Finish with ¼ cup chopped parsley and a squeeze of lemon juice before serving. This version keeps the heartiness but adds bright, tangy notes perfect for a lighter lunch. 🍋

Smoky BBQ Bean Soup

Mix ½ cup BBQ sauce (like Sweet Baby Ray’s Original) into the tomato paste before adding the broth. Add 1 tbsp apple cider vinegar for tang and 1 tsp liquid smoke for that classic smoky flavor.

Top with crumbled bacon (or smoked tofu for vegan) and pickled red onions for a sweet, smoky, and tangy twist that’s perfect for game day or a cozy dinner. 🔥

Lentil Boost for Extra Heartiness

Add ½ cup dried green or brown lentils to the bean mix for a protein-packed upgrade. Lentils cook faster than beans, so reduce the simmering time to 30-40 minutes once the beans are tender.

The lentils add a meaty texture while keeping the soup creamy. This variation is perfect for those who want extra fiber and plant-based protein without sacrificing texture. 💪

Herb-Infused Garlic Lover’s Version

Double the garlic to 8 cloves and add 1 tbsp fresh rosemary (finely chopped) and 1 tsp garlic powder during the sautéing step. For extra depth, stir in 2 tbsp minced shallots with the onions.
