The bacon is non-negotiable—thick-cut, smoked gives that perfect crispy edge while infusing the broth with deep, smoky flavor. Costco or Whole Foods carry the best quality, but any grocery store's thick-cut will work. Look for good marbling in the meat. Navy beans are the secret weapon here—they hold their shape beautifully while soaking up all that smoky, molasses-kissed goodness. Bob's Red Mill dried beans are my go-to, but any dried navy beans will do. No need to soak them; just rinse well before adding to the pot. The molasses needs to be unsulphured and dark—the lighter varieties won't give that rich, caramel-like depth you're craving. I always grab mine from Trader Joe's when I'm restocking my pantry staples.
No thick-cut bacon? Regular bacon works in a pinch, but it won't crisp up as nicely. Fresh herbs can be swapped for dried at one-third the amount—just make sure they're labeled as culinary thyme, not French. The tomato paste can be skipped if you're avoiding it, but I find it adds a nice umami depth that balances the sweetness of the molasses. Trader Joe's tomato paste in the squeeze tube is perfect for this—no waste, and it keeps for months. For the broth, homemade is ideal, but low-sodium store-bought works fine if you're short on time. Just add an extra pinch of salt at the end. The crusty bread is truly optional, but a good sourdough or baguette from your local bakery makes this feel like a proper pub experience.
This soup tastes even better the next day as all the flavors meld together. Store in an airtight container in the fridge for up to 5 days, or freeze for 3 months—portion into containers before freezing for easy lunches. The bacon bits will crisp up again when reheated, so don't skip that final step. For serving, I like to toast the bread slices and rub them with a garlic clove before serving. The soup reheats beautifully—just add a splash of water or broth if it's too thick after refrigeration. Leftovers make fantastic lunches, and the aroma alone will have everyone in your house gathering around the table.
Why You'll Love This Recipe
- One-Pot Magic: I swear by this recipe because it’s literally dump-and-simmer. No fancy techniques—just brown the bacon, toss in the onions and carrots, add the soaked beans and molasses, then let it bubble away. The navy beans soften into that perfect creamy texture while the bacon renders its smoky magic right into the pot. No extra dishes, no stress.
- Molasses Magic: Honestly, that tablespoon of molasses is what turns this from good to ridiculously good. It’s not too sweet—just enough to deepen the richness and cut through the saltiness of the bacon. The first time I skipped it, I immediately regretted it. Now? It’s non-negotiable.
- Leftovers That Win: This soup only gets better the next day. The flavors meld into something even more complex, and the beans absorb all the smoky, savory goodness. I make a double batch on Sundays because it’s my go-to for lazy lunches, potlucks, or when I need to feed a crowd without slaving away. Plus, it reheats like a dream.
- Budget-Friendly Feast: Bacon and molasses might sound fancy, but they stretch across four hearty servings. The dried navy beans are a pantry staple, and onions and carrots are always cheap. I’ve fed my whole family (plus a couple of friends) for under $10 with this recipe—no compromises on taste, just smart spending.
Step-by-step instructions for McGuire's Irish pub senate bean soup
This hearty soup builds rich, smoky depth through careful layering and patience—don't rush the bacon or skip the molasses.
Render the Bacon and Build the Flavor Base
Cut the 12 oz bacon into ¼-inch pieces and place them in a large Dutch oven over medium heat. Let the bacon cook undisturbed for 8-10 minutes until the fat renders out and the edges turn deep golden brown. This rendered fat is the foundation of your soup's richness—don't drain it.
Once the bacon is crispy, use a slotted spoon to transfer it to a paper towel-lined plate, leaving all the fat in the pot. Add the chopped yellow onion, chopped carrots, and chopped celery stalks to the pot. Cook for 5 minutes, stirring occasionally, until the vegetables begin to soften and release their aromas. This step develops the soup's sweet, earthy base that will carry through the entire cooking process.
Add Aromatics and Deepen the Flavor Profile
Stir in the minced garlic cloves and cook for 30 seconds until fragrant—this prevents the garlic from burning, which would make the soup bitter. Add the 2 whole bay leaves and 2 whole thyme sprigs, giving them a gentle stir to distribute the herbs evenly throughout the vegetables.
Pour in the 0.5 cup molasses and 1 tbsp tomato paste, stirring to coat the vegetables completely. Cook for 2 minutes, allowing the molasses to caramelize slightly and deepen its rich, smoky flavor. This is where the soup starts to develop its signature complexity—don't skip this step, as it creates the soul of the dish.
Combine All Ingredients and Simmer
Add the 2 cups dried navy beans, 4 cups chicken broth, and 4 cups water to the pot. Stir well to combine, then bring the mixture to a gentle boil over medium-high heat. Once boiling, reduce the heat to low, cover the pot, and let the soup simmer for 1 hour and 15 minutes. This long simmer allows the beans to soften completely and the flavors to meld together.
After the initial hour, check the soup and add water as needed to maintain the proper consistency—it should be thick but still spoonable. Stir in the 1.5 tsp salt and 0.5 tsp black pepper, adjusting to taste. The soup should now have a rich, smoky aroma with layers of sweetness from the molasses and depth from the bacon and vegetables.
Finish and Serve
Remove the pot from heat and let the soup sit covered for 10 minutes. This resting period allows the flavors to settle and the soup to thicken slightly. Skim off any excess fat that has risen to the surface if desired—though I like to leave a little for extra richness.
Ladle the soup into bowls and top each serving with 2 slices of crusty bread. The bread will soak up the flavorful broth, creating the perfect bite. Serve immediately while the soup is hot, as the flavors are at their peak when enjoyed fresh from the pot.
Pro Tips For Making Mcguire'S Irish Pub Senate Bean Soup
- Cook Bacon Low and Slow: I learned this the hard way—cranking the heat to render bacon fast turns it greasy and dulls the flavor for the soup. Instead, cook it on medium-low for 10-12 minutes, stirring occasionally, until it’s crisp but not burnt. The slow render keeps the fat flavorful and the bacon crisp enough to hold its shape in the soup.
- Parboil Beans First: Skipping this step is where most people go wrong. Navy beans need a head start—soak them overnight or boil them for 30 minutes before adding to the pot. This cuts cooking time by nearly half and prevents that sad, grainy texture. (Yes, even if you’re impatient like me.)
- Sweat Onions Until Soft: Don’t rush the onion—cook it in the bacon fat until it’s translucent and just starting to caramelize (about 8-10 minutes). This builds depth of flavor that a quick sauté misses. If they’re still crunchy, the soup will taste raw and unfinished.
- Stir in Molasses Last: Molasses burns faster than you’d think, and adding it too early turns the soup bitter. Wait until the beans are almost tender, then stir it in off the heat or on the lowest setting. This keeps the rich, caramel notes intact—no sad, charred aftertaste.
Regional styles of this recipe
Boston Pub Tradition
This soup is a direct descendant of the classic Irish pub bean soup served at McGuire's Irish Pub in Boston—a place where I spent many a cold New England winter nursing a pint while my Nonna would scold me for not eating enough.
The original recipe hails from Boston's Irish community, where hearty bean soups were a staple for feeding large families and pub crowds alike. The key to its pub authenticity is the smoked bacon and molasses combination, which gives it that signature depth that separates it from other bean soups.
I remember the first time I tasted it there—the rich, smoky aroma alone could fill an entire room. 🥓
Irish-American Adaptation
While the roots are undeniably Irish, this version has been adapted to suit American tastes—particularly the addition of molasses, which wasn't traditionally used in Irish bean soups but became a staple in New England kitchens.
The Irish would often use a combination of bacon and salt pork, but the molasses twist came from American settlers who wanted to add a touch of sweetness to balance the richness.
I've found that using unsulphured molasses from Trader Joe's makes all the difference in achieving that perfect balance of sweet and smoky. The Irish might have used a bit more broth, but we've kept it hearty while maintaining that pub-style richness. 🍯
New England Game Day Classic
This soup became a staple at Boston sports bars during football season, where it was served alongside corned beef sandwiches and pints of Guinness. The slow-cooked beans and crispy bacon bits make it the perfect handheld dish for game day—no utensils required!
I've hosted countless watch parties in my tiny Boston apartment where this soup was the star. The secret to its popularity is its versatility—it's filling enough to be a meal on its own but light enough to pair with a cold beer.
The molasses adds a subtle sweetness that cuts through the richness of the bacon, making each spoonful irresistible. ⚽
Family-Style Serving
In Irish pubs, this soup is traditionally served family-style in large cast-iron pots, allowing everyone to help themselves. I've replicated that experience by making it in a Dutch oven, which keeps the soup warm and lets the flavors meld together beautifully.
The crispy bacon bits on top are non-negotiable—they add texture and a salty crunch that contrasts perfectly with the soft beans. I always serve it with crusty sourdough bread from my local bakery, which soaks up the broth like a dream.
The Irish might have eaten it with brown soda bread, but we've adapted it to suit our local tastes. 🍞
Slow-Cooker Adaptation
For those busy weeknights, I've tested this recipe in a slow cooker with great success. Simply combine all the ingredients (except the bacon) in the slow cooker, cook on low for 6-7 hours, then crisp the bacon separately and stir it in at the end.
The slow cooker method is perfect for when you want to come home to a warm, ready-to-serve meal. I've even made it in my Instant Pot by cooking on high pressure for 30 minutes after the initial sautéing, then adjusting the seasoning.
The key is patience—rushing the cooking process will result in tough beans and underdeveloped flavors. ⏳
Modern Twists
While this is a classic recipe, I've experimented with a few modern twists that still honor the original. Adding a splash of stout beer (like Guinness) to the broth adds a malty depth that pairs beautifully with the molasses.
For a vegetarian version, I've swapped the bacon for smoked paprika and liquid smoke, though it won't have the same richness. Another fun twist is topping the soup with a sprinkle of grated Parmesan cheese before serving—it adds a nice umami finish.
The beauty of this recipe is that it's forgiving enough to allow for creativity while still delivering that classic pub taste. 💡

Frequently asked questions
Why does McGuire's style use molasses in bean soup?
The molasses adds a deep, caramel-like sweetness that balances the smoky bacon perfectly while giving the soup its signature richness. This Irish-American twist creates that perfect harmony of flavors—sweet, salty, and umami—that makes this soup so irresistible.
Can I substitute regular bacon for thick-cut?
Yes, but expect less crispy edges. Regular bacon works in a pinch, though thick-cut smoked bacon gives that authentic pub-style crunch. For best results, cook it longer until it crisps up nicely.
How do I fix soup that's too thick after refrigeration?
Simply add ½ cup water or broth at a time while reheating, stirring until it reaches your desired consistency. The soup thickens naturally as it cools, so don't worry—it's normal!
What's the best way to reheat leftovers?
Gently reheat on the stove over low heat with a splash of water or broth. For extra crispiness, toast the bacon bits separately and stir them back in at the end. The slow reheating preserves all those rich flavors.
Can I make this soup vegetarian?
For a vegetarian version, swap the bacon for smoked paprika (1 tbsp) and liquid smoke (½ tsp)**—though it won't have the same richness. The molasses and herbs will still give that comforting depth.
