Slow Cooker White Bean Soup
Ingredients
Instructions
- Place the beans in a large bowl and cover with water by at least 3 inches. Soak overnight, then drain and rinse.
- Heat the olive oil in a skillet over medium heat. Add the onion, carrots, and celery and cook for 6 minutes. Stir in the garlic for 30 seconds, then transfer everything to a 5- to 6-quart slow cooker.
- Add the beans, thyme, rosemary, paprika, optional red pepper flakes, bay leaf, broth, water, 1 teaspoon salt, and black pepper. Stir to combine.
- Cover and cook on low for 7 to 8 hours or on high for 3½ to 4½ hours, until the beans are completely tender. Add hot water during cooking if the beans are no longer covered.
- Remove and discard the bay leaf. Transfer 2 cups of soup to a blender and carefully purée until smooth, or use an immersion blender for several brief pulses.
- Return the purée to the slow cooker. Stir in the optional miso or nutritional yeast, lemon juice, remaining salt, parsley, and chives. Add broth or water to adjust the consistency.
- Taste and season with more salt and pepper. Ladle into bowls, drizzle with olive oil, and serve with crusty bread.

Why This Recipe Works
- Soaked dried beans: cook evenly and develop a creamy interior.
- Sautéed aromatics: build more flavor than adding them raw.
- Partial blending: thickens the soup naturally without cream.
- Lemon and herbs: balance the earthy beans.
Choosing White Beans
Cannellini beans are large and creamy, while navy beans make a slightly smoother soup. Freshly purchased dried beans soften more reliably than packages stored for years.
Helpful Tips
- Keep the beans covered with liquid throughout cooking.
- Wait until the beans are tender before adding lemon.
- Blend carefully because hot soup expands.
- The soup will become thicker after refrigeration.
Variations
- Greens: stir in baby spinach or chopped kale near the end.
- Tomato: add diced tomatoes after the beans are tender.
- Smoky: add a ham hock or smoked turkey leg.
- Italian: finish with basil and Parmesan.
Serving Suggestions
Serve with crusty bread, garlic toast, or a green salad. A spoonful of pesto or a sprinkle of Parmesan also works beautifully.
Storage and Reheating
Refrigerate for up to 5 days or freeze for 3 months. Reheat gently with a splash of broth or water to loosen the texture.
Frequently Asked Questions
Do I need to soak the beans first?
Soaking helps the beans cook evenly and more predictably. Unsoaked beans need extra liquid and may require several additional hours.
Can I make this with canned beans?
Yes. Use four drained 15-ounce cans, reduce the liquid to about 5 cups, and cook on low for 2 to 3 hours.
How do I make the soup creamy without dairy?
Blend about 2 cups of the cooked soup and stir it back in. The bean starch creates a naturally creamy texture.
Why are my beans still hard?
Old beans, hard water, acidic ingredients, or insufficient cooking time can delay softening. Keep cooking with enough hot liquid until tender.
Can I add meat?
Yes. A smoked ham hock, cooked sausage, or diced ham can be added, but the soup is flavorful and satisfying without meat.
How long does white bean soup keep?
Refrigerate for up to five days or freeze for up to three months. The soup thickens as it cools, so add broth when reheating.
