Ingredients for boston bean soup

Six hearty servings of New England comfort—just these simple ingredients transform into soup so rich it feels like a hug.

The pork shoulder is the star here—bone-in for maximum flavor, but boneless works in a pinch. I grab mine from Costco when I can, but any grocery store's pork shoulder will do. Look for good marbling—the more fat, the better it'll get tender. The bacon and ham? Smoked varieties are non-negotiable for that classic New England taste. If you can't find smoked ham, regular ham with a dash of liquid smoke works too. For the beans, dried navy beans give you that authentic texture, but canned beans in a pinch (rinsed well) will save you time.

No pork shoulder? Chicken thighs work surprisingly well—they stay tender and add a nice contrast. Swapping bacon for smoked turkey bacon keeps it meaty but lighter. The carrots and celery can be prepped ahead and stored in the fridge for 3 days (they'll even keep in the freezer for 2 months). Fresh thyme is ideal, but dried thyme at one-third the amount gets you close. The tomato paste? Trader Joe's squeeze tubes are perfect here—no waste, and they keep forever. For extra depth, add a 1/2 tsp smoked paprika with the tomato paste.

This soup tastes even better the next day—make a double batch and freeze half. The broth keeps for 5 days in the fridge, but the beans? They get even more tender. I like to portion mine into 4-cup containers so I can reheat just what I need. For serving, crusty bread is a must—it soaks up that rich broth like a dream. Leftovers freeze beautifully for 3 months, though I rarely have any to spare.

Step-by-step instructions for New England-style bean soup

This hearty soup delivers rich, smoky depth with every spoonful—let's build it layer by layer.

Heat the 2 tbsp olive oil in a large Dutch oven over medium heat. Add the 8 oz smoked bacon and cook for 6-8 minutes until deep golden brown and crispy, stirring occasionally. Remove bacon with a slotted spoon and set aside, leaving the fat in the pot.

In the same pot, add the 1.5 lb pork shoulder cut into cubes and cook for 5 minutes until lightly browned. Push the pork to one side and add the 4 oz diced smoked ham. Cook for 2 minutes until the ham begins to color. Here's the thing—this smoky base is where all the magic starts, so don't rush this step.

Add the 1 whole chopped yellow onion, 3 medium sliced carrots, and 3 chopped celery stalks to the pot. Cook for 5-6 minutes until the vegetables soften slightly and begin to release their natural juices. Stir in the 4 cloves minced garlic and cook for 30 seconds until fragrant—this prevents the garlic from burning.

Sprinkle in the 2 tbsp tomato paste and stir well to coat the vegetables. Cook for 1 minute until the tomato paste darkens slightly. This step develops the soup's rich, slightly sweet foundation that balances the smoky flavors perfectly.

Pour in the 6 cups chicken broth and add the 2 whole bay leaves and 1 tbsp chopped fresh thyme. Stir in the 2 cups soaked navy beans (drained), the reserved bacon, and the pork shoulder. Bring to a gentle boil, then reduce heat to low-medium and cover partially. Simmer for 1.5 hours until the beans are tender and the pork is fork-tender.

I know it seems like a long time, but this slow cook is what transforms tough pork into melt-in-your-mouth pieces. Stir occasionally to prevent sticking, and if the soup gets too thick, add ½ cup water at a time. The beans should be soft but still hold their shape.

Remove the bay leaves and adjust seasoning with 1.5 tsp salt and 0.5 tsp black pepper. Taste and add more salt if needed—this soup should be rich but not overwhelming. The beans should be seasoned throughout, not just on the surface.

For the final touch, I like to stir in 1 tablespoon olive oil right before serving. This adds a silky finish that cuts through the hearty flavors. Ladle into bowls and serve with crusty bread to soak up every last drop of that smoky, savory broth.

Let the soup rest for 10 minutes before serving. This allows the flavors to meld completely and the beans to absorb the broth. The soup will thicken slightly as it rests, which is exactly what you want for that perfect spoonful.

This New England-style bean soup is all about the balance—smoky bacon, tender pork, sweet carrots, and earthy beans all coming together in one comforting bowl. The longer it sits, the better it tastes, so don't be afraid to make extra for leftovers.

Creative variations of these flavors

Classic White Bean Twist

Swap the navy beans for 2 cups white beans (cannellini or great northern) for a lighter, creamier texture. The beans hold their shape beautifully while absorbing the smoky broth.

I like to add ½ cup diced fennel with the carrots and celery—it adds a subtle licorice note that pairs perfectly with the pork. For extra richness, stir in ¼ cup heavy cream at the very end. 🌟

Spicy Cajun Kick

Transform this into a Louisiana-inspired version by adding 1 tbsp Cajun seasoning (like Tony Chachere's) with the pork shoulder. For heat, include 1-2 sliced jalapeños with the bacon.

Finish with 1 tbsp hot sauce (like Crystal or Tabasco) and serve with cornbread instead of crusty bread. The smoky-sweet base becomes a spicy, soul-warming stew.

Vegetarian Adaptation

Skip the pork entirely and use 1 lb smoked tofu or mushrooms (like cremini or portobello) for umami depth. Add 1 tbsp soy sauce and 1 tsp liquid smoke to mimic the meaty flavor.

For protein, include 1 cup chickpeas with the navy beans. The result is still hearty and satisfying—just plant-based. 🌱

Slow Cooker Version

For hands-off cooking, brown the bacon and pork in a skillet first, then transfer everything to a 6-quart slow cooker. Add all ingredients as directed and cook on low for 6-7 hours or high for 4 hours.

The slow cooker keeps the beans tender without overcooking the pork. I like to stir in ½ cup shredded cheddar at the end for extra comfort.

Holiday Feast Upgrade

Make this a showstopper for Thanksgiving by adding ½ cup cranberry sauce (homemade or store-bought) and ½ cup diced roasted chestnuts. The tart-sweet cranberries cut through the richness, while the chestnuts add a festive crunch.

Serve in a Dutch oven at the table so guests can ladle their own bowls—it’s perfect for family-style meals. 🍂

Instant Pot Hack

For a 30-minute version, sauté the bacon and pork in the Instant Pot, then add all ingredients and seal the lid. Cook on high pressure for 18 minutes, then quick-release.

The beans will be perfectly tender without overcooking the pork. Finish with a splash of apple cider vinegar (1 tbsp) for brightness. This is my go-to for busy weeknights!
