How to Make 15 Bean Soup in the Slow Cooker
This recipe is the definition of set it and forget it. Here’s how it’s done:
- Rinse and sort your beans to remove any debris or tiny pebbles. No need to pre-soak—yay for shortcuts!
- In your slow cooker, combine the rinsed beans, onion, garlic, carrots, celery, diced tomatoes (with juice), broth, ham, and spices.
- Stir it all together, pop in the bay leaf, and cover.
- Cook on LOW for 8-10 hours or HIGH for 5-6 hours, until the beans are tender and the house smells heavenly.
- Before serving, stir in the lemon juice for a little zing and season with salt to taste.
- Remove the bay leaf, ladle into bowls, garnish with parsley if you’re feeling fancy, and dig in!
Tips for the Best Slow Cooker Soup
- Ham hock vs. diced ham: Ham hocks add more flavor and depth, but diced ham works great for a quicker option.
- Too thick? Add a splash of broth or water at the end if it thickens too much while cooking.
- Make it meatless: Just skip the ham and use vegetable broth—it’s still hearty and delicious.
- Storing leftovers: This soup keeps beautifully in the fridge for 3-4 days and freezes well for up to 3 months. Perfect for batch cooking!
A Little Story from My Kitchen 💬
This soup became my cold-weather go-to after a chilly Sunday when I threw it together with pantry staples and whatever veggies were in the fridge. My husband—who swears he’s “not a soup guy”—ended up going back for thirds. Now it’s on regular rotation in our house, especially when I need dinner that basically cooks itself while I’m wrangling our toddler or sneaking in a quick episode of The Great British Bake Off. 😉

FAQs About 15 Bean Soup in the Slow Cooker
Can I use canned beans instead of dry?
You can, but I don’t recommend it here—the magic happens when the dry beans soak up all the flavor during the slow cooking process. Plus, the texture is unbeatable.
Can I make this in an Instant Pot?
Yes! While this recipe shines in the slow cooker, if you’re short on time, check out The Kitchn’s guide on cooking beans in a pressure cooker for tips on adapting it to your Instant Pot.
Is this soup spicy?
Nope—it’s warm and savory but not spicy. If you like heat, toss in a pinch of red pepper flakes or a dash of hot sauce.
