Ham and Bean Soup Recipe
This scientifically optimized ham and bean soup leverages starch gelatinization from dry navy beans and collagen extraction from ham hocks to build a rich, naturally thick broth without heavy dairy.
- Starch gelatinization from dry navy beans creates a velvety, naturally thickened broth without flour or cornstarch.
- Slow-simmered ham hocks release gelatin and collagen, providing a rich mouthfeel and deep savory flavor.
- A balanced mirepoix base combined with a splash of acid at the end cuts through the heavy proteins and fats.
The secret to a superior ham and bean soup lies in controlling starch gelatinization and collagen extraction rather than relying on flour-based thickeners. Similar to the starch breakdown in a classic Split Pea Soup, simmering dry navy beans directly in a mineral-rich broth allows the bean starches to swell and burst, naturally bodying the liquid. This technique yields a clean, velvety texture that highlights the pork's savory depth.
Never use canned beans if you want a truly cohesive soup matrix.
Dry beans release amylose starches during their long simmer, which bond with the cooking liquid to form a stable suspension. Additionally, using a heavy-bottomed Dutch oven provides high thermal mass, ensuring a steady, gentle simmer that prevents the beans from breaking apart prematurely.
Building the flavor profile starts with sweat-sautéing a classic mirepoix of onions, carrots, and celery in rendered ham fat or olive oil. This step initiates the Maillard reaction, transforming simple sugars and amino acids into complex, savory compounds that form the soup's aromatic foundation. If you have leftover ham from a previous meal, such as a holiday feast, searing the diced meat first adds caramelized edges that deepen the overall flavor profile. For a similar comforting profile, you might also enjoy our Ham and Potato Corn Chowder.
Do not salt the cooking liquid until the beans have fully softened. Just as when preparing traditional Charro Beans, salt and acidic ingredients can bind to the bean skins, preventing water absorption and leaving you with tough, chalky beans.
Ham and Bean Soup
Ingredients
- 1 pound (450g) dry navy beans, rinsed and picked through
- 1 tablespoon extra-virgin olive oil
- 1 large yellow onion, finely diced
- 3 medium carrots, diced
- 3 ribs celery, diced
- 4 cloves garlic, minced
- 1 smoked ham hock (about 1 pound)
- 2 cups diced leftover ham
- 6 cups low-sodium chicken stock
- 2 bay leaves
- 1 teaspoon dried thyme
- Freshly ground black pepper, to taste
- 1 tablespoon apple cider vinegar
Directions
- Place the dry navy beans in a large bowl, cover with at least 3 inches of cold water, and let soak for 8 to 12 hours. Drain and rinse.
- Heat the olive oil in a large Dutch oven over medium heat. Add the onion, carrots, and celery, cooking for 6 to 8 minutes until the vegetables are softened and the onions are translucent.
- Stir in the minced garlic, bay leaves, and dried thyme. Cook for 1 minute until highly fragrant, taking care not to burn the garlic.
- Add the soaked and drained beans, the smoked ham hock, and the chicken stock to the pot. Bring the mixture to a boil over high heat, then immediately reduce the heat to low, cover, and simmer gently for 1.5 to 2 hours, or until the beans are completely tender.
- Remove the ham hock from the soup and let it cool slightly. Shred the meat off the bone, discarding the skin, fat, and bones, then return the shredded meat to the pot along with the diced leftover ham.
- Use the back of a wooden spoon to mash a small portion of the beans against the side of the pot to release more starch and thicken the broth. Stir in the apple cider vinegar, season with black pepper to taste, and simmer uncovered for an additional 10 minutes before serving.
Notes
Always soak your beans overnight to ensure even cooking and optimal starch release.
- We recommend using Diamond Crystal Kosher Salt; if substituting Morton's kosher salt, reduce the volume by half to prevent over-salting the delicate bean broth.
- The addition of apple cider vinegar at the very end of cooking lowers the pH slightly, which brightens the heavy, fatty flavors and structurally tightens the starch network for a cleaner mouthfeel.
- If you skip the overnight soaking step, the beans will cook unevenly, leaving some chalky and others mushy. Prevent this by performing a quick-boil soak: boil the beans for 2 minutes, cover, and let sit off the heat for 1 hour before draining.
- After 24 hours in the refrigerator, the starch retrogradation process will cause the soup to thicken significantly into a gel-like state. Restore the original velvety texture by stirring in 1/4 cup of warm water or stock per serving during reheating.
- If you do not own a heavy Dutch oven, a standard stockpot can be used, but you must reduce the heat to its lowest setting and stir every 15 minutes to prevent the starches from settling and scorching on the thinner bottom.
Serving Suggestions
Complete this hearty soup by pairing it with elements that offer a sharp textural contrast or a bright, acidic counterpoint to cut through the rich pork fats.
- Warm, crusty sourdough bread (perfect for sweeping up the starch-rich broth).
- A crisp green salad dressed with a sharp lemon vinaigrette to cleanse the palate between spoonfuls.
- A slice of jalapeño cornbread, which provides a sweet and spicy contrast to the smoky ham.
- A side of roasted brassicas, such as those featured in our Roasted Broccoli and Cheddar Soup, to add a charred, bitter edge that balances the soup's sweetness.
Storage and Reheating
Store leftover soup in an airtight glass container in the coldest zone of your refrigerator for up to 4 days. Glass is highly preferred over plastic containers. It does not absorb the smoky pork oils or stain from the carotenoids in the carrots.
For long-term storage, freeze the soup in heavy-duty freezer bags for up to 3 months. Note that the beans will soften slightly upon thawing due to ice crystal formation disrupting their cellular walls.
Starch retrogradation will make the cold soup appear solid, but it liquefies quickly when heated.
The best reheating method is on the stovetop over medium-low heat. Add a splash of water or chicken broth to loosen the starch gel, cover, and stir frequently until it reaches a simmer. This gentle heating prevents the starches from scorching on the bottom of your pot.
Avoid high-power microwaving, which heats unevenly and can cause the beans to burst.
Ingredient Substitutes
You can easily adapt this recipe to suit your pantry inventory with a few simple technical adjustments.
- Dry Navy Beans: Substitute with dry Great Northern beans or Cannellini beans at a 1:1 ratio. No changes to cooking time or soaking technique are required.
- Smoked Ham Hock: Substitute with smoked turkey wings or shanks at a 1:1 ratio. Ensure you simmer the turkey for the full duration to extract enough collagen to mimic the pork's body.
- Chicken Stock: Substitute with vegetable stock or water at a 1:1 ratio. If using water, increase the aromatics and add a pinch of MSG or soy sauce to compensate for the lost glutamates.
- Apple Cider Vinegar: Substitute with fresh lemon juice at a 1:1 ratio. Add it strictly off the heat to preserve the volatile citric acid compounds.
Mastering this classic soup is a masterclass in utilizing simple starches and proteins to build luxurious textures. Keep your simmer gentle, adjust your seasoning at the very end, and enjoy a perfectly executed bowl of comfort.
