Cozy Up with a Bowl of Hearty 15-Bean Soup

The first time I ever had 15-bean soup, I was a struggling college student, far from home and even further from my mother’s cooking. A local diner, smelling of coffee and simmering goodness, offered a bottomless bowl for just a few dollars. That steaming, flavorful broth, packed with a variety of beans and savory vegetables, was pure comfort in a bowl – a little taste of home that warmed me from the inside out and fueled countless late-night study sessions. To this day, the aroma of a simmering pot of bean soup instantly transports me back to that tiny diner booth, a reminder that even the simplest meals can offer profound comfort and connection.

Recipe Overview

• Prep Time: 20 minutes (plus overnight soaking)
• Cook Time: 9-11 hours on LOW or 5-7 hours on HIGH, plus 20-30 minutes
• Total Time: 9 hours 40 minutes to 11 hours 50 minutes on LOW, or 5 hours 40 minutes to 7 hours 50 minutes on HIGH
• Servings: 8
• Yield: Approximately 10-12 cups
• Dietary Type: Can be made Gluten-Free and Dairy-Free

Ingredients

• 1 onion, minced
• 6 garlic cloves, minced
• 1 tablespoon vegetable oil
• 2 teaspoons minced fresh thyme (or 1/2 teaspoon dried)
• 6 cups low sodium chicken broth
• 12 ounces white mushrooms, quartered
• 1 1/4 cups fifteen-bean soup mix (flavoring packet discarded, picked over, pre-soaked overnight, drained)
• 4 ounces bacon (about 4 slices)
• 1/2 ounce dried porcini mushrooms, rinsed and minced
• 2 bay leaves
• 8 ounces swiss chard, stemmed and leaves sliced 1/2 inch thick
• 1 (14 1/2 ounce) can whole tomatoes, drained and chopped medium
• Salt, to taste
• Pepper, to taste

Equipment Needed

• Large Bowl (for soaking beans)
• Microwave-Safe Bowl
• Slow Cooker (6-quart or larger recommended)
• Large Spoon
• Knife
• Cutting Board

Instructions

1. Begin by preparing the aromatic base. In a microwave-safe bowl, combine the minced onion, minced garlic, vegetable oil, and minced fresh thyme. Microwave, stirring occasionally, until the onion is softened, approximately 5 minutes. This step helps to jumpstart the flavors and create a deeper, richer base for the soup.

2. Transfer the microwaved onion mixture to a slow cooker.

3. Introduce the primary liquids and flavor enhancers. Stir in the low sodium chicken broth, quartered white mushrooms, soaked and drained fifteen-bean soup mix, bacon, minced porcini mushrooms, and bay leaves into the slow cooker. The combination of chicken broth and porcini mushrooms creates a savory depth of flavor that beautifully complements the beans.

4. Cover the slow cooker and set it to either LOW or HIGH. Cook on LOW for 9-11 hours or on HIGH for 5-7 hours, or until the beans are tender. The longer cooking time on LOW allows the flavors to meld and develop more fully, but the HIGH setting is a great option when you’re short on time.

5. Once the beans are tender, let the soup settle for 5 minutes. This allows any excess foam or scum to rise to the surface.

6. Remove any excess fat from the surface of the soup using a large spoon. This step helps to create a cleaner, less greasy final product.

7. Discard the bacon and bay leaves. The bacon has imparted its smoky flavor, and the bay leaves have contributed their subtle herbal notes.

8. Add the final vegetables. Stir in the sliced swiss chard and chopped tomatoes, cover, and cook on HIGH until the chard is tender, approximately 20-30 minutes. Adding the chard and tomatoes at the end ensures that they retain some texture and freshness.

9. Season the soup to taste with salt and pepper. Remember that the bacon and chicken broth already contain salt, so start with a small amount and adjust as needed.

10. Serve hot and enjoy!

Expert Tips & Tricks

• Bean Soaking is Key: Don’t skip the overnight soaking for the bean mixture. Soaking helps to soften the beans, reduce cooking time, and improve their digestibility. If you forget to soak them overnight, you can use a quick-soak method: cover the beans with water in a pot, bring to a boil, boil for 2 minutes, then remove from heat and let sit for 1 hour before draining and rinsing.

• Bacon Alternatives: If you’re looking for a vegetarian or vegan option, you can omit the bacon and add a tablespoon of smoked paprika or a few drops of liquid smoke to achieve a similar smoky flavor. You could also use diced smoked tofu.

• Add Acidity: A splash of vinegar or lemon juice at the end can brighten the flavors and balance the richness of the soup.

• Thicken the Soup: If you prefer a thicker soup, you can use an immersion blender to partially blend some of the beans. Alternatively, you can remove a cup or two of the soup, blend it in a regular blender, and then return it to the pot.

• Spice it Up: For a spicier soup, add a pinch of red pepper flakes or a diced jalapeño along with the onion and garlic.

Serving & Storage Suggestions

This 15-bean soup is delicious served hot with a crusty loaf of bread or some cornbread. It also pairs well with a simple green salad. Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. For longer storage, the soup can be frozen for up to 2-3 months. To reheat, simply warm the soup in a pot over medium heat or in the microwave. If frozen, thaw the soup overnight in the refrigerator before reheating.
