Do I have to soak navy beans?
Soaking is not required, but it helps the beans cook more evenly and a little faster. For this recipe, an overnight soak is ideal. If you forgot, a quick soak works too.
How do I quick-soak beans?
Rinse the beans, add them to a pot, cover with plenty of water, and boil for 2 minutes. Turn off the heat, cover, and let sit for 1 hour. Drain, rinse, and continue with the recipe.
Why are my beans still hard?
Most often it is age. Older dried beans can take longer no matter what. Also, keep the soup at a gentle simmer and make sure the beans stay covered with liquid. In general, wait to add strong acidic ingredients like lemon or vinegar until the end.
What about tomato paste? A small amount of tomato paste is usually fine, especially in a big pot of broth, but acidity can sometimes slow softening depending on bean age and water chemistry. Adding the tomato paste after the beans are nearly tender helps reduce the risk. If you skipped soaking or your beans are older, wait until the beans are clearly tender before stirring it in.
Can I make this without ham?
Yes. Swap the ham for 1 extra teaspoon smoked paprika and use vegetable broth. For extra savoriness, add 8 ounces sliced mushrooms with the onions, or stir in a tablespoon of soy sauce at the end.
How do I thicken navy bean soup?
The easiest way is to blend 1 to 2 cups of soup and stir it back in. You can use an immersion blender right in the pot, or a standard blender in batches.
Can I make it in a slow cooker?
Yes, with soaked beans. Sauté the vegetables first for best flavor, then cook on low 7 to 8 hours or until the beans are tender. Add the lemon at the end.
