America's Test Kitchen's Boston baked beans recipe delivers that iconic slow-cooked, smoky-sweet flavor with crispy bacon and tender beans—just like your favorite New England diner.
The secret lies in browning the beans first, then simmering them with molasses, spices, and just the right amount of liquid to create a thick, glossy sauce.
I've tested countless variations, and this method consistently produces beans that are tender yet hold their shape, with deep caramelized flavors that develop over hours of gentle cooking.

The bacon adds texture and depth, making each bite satisfyingly hearty. This is the kind of recipe that tastes even better the next day as flavors meld together.
Perfect for holiday gatherings, potlucks, or weeknight dinners, these beans reheat beautifully and taste just as good cold. The method is foolproof once you understand the key steps—browning, simmering, and timing. Let's get started on creating your best batch yet.
Ingredients for america's test kitchen boston baked beans
Pantry staples plus a few key ingredients transform into diner-style beans with smoky-sweet perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Navy Beans (Dried) 🌾 | 2 cups | Unsoaked, no need to soak |
| Thick-Cut Bacon 🥓 | 8 oz | Regular or applewood smoked |
| Unsweetened Molasses 🍯 | ½ cup | Blackstrap preferred for depth |
| Yellow Onion 🧅 | 1 whole | Medium, chopped |
| Garlic Cloves 🧄 | 3 cloves | Fresh, minced |
| Tomato Paste 🍅 | 2 tbsp | No salt added |
| Dijon Mustard 🍯 | 1 tbsp | High-quality for tang |
| Apple Cider Vinegar 🍎 | 1 tbsp | For brightness |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Ground Allspice 🌿 | ¼ tsp | Key for smoky depth |
| Ground Cloves 🌶️ | ⅛ tsp | Freshly ground preferred |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Brown Sugar 🍚 | ¼ cup | Light or dark |
| Beef Broth 💧 | 2 cups | Low-sodium preferred |
The beans are the star, so don't skimp on quality. Navy beans work best here—they hold their shape beautifully after long cooking. Most grocery stores carry them in the canning aisle or bulk section. If you can't find them, great northern beans are a solid substitute. The bacon? Thick-cut is ideal—it renders fat slowly, which is perfect for browning the beans. I always grab applewood smoked bacon from the deli counter at Whole Foods or Costco for that extra depth of flavor. Regular bacon works just fine, but the smoked variety adds that authentic diner taste.
No molasses? Maple syrup at half the amount gets you close, but the depth won't be quite the same. Short on mustard? Yellow mustard works in a pinch, but Dijon adds that perfect tang. The tomato paste can be swapped for 1/4 cup crushed tomatoes if you're in a hurry, though it won't caramelize as nicely. For the spices, Penzeys or the bulk bins at natural food stores have the freshest ground allspice and cloves. If you're missing one of these spices, smoked paprika at half the amount can add a similar smoky note. The brown sugar can be light or dark—it's mostly about balancing the flavors, not the color.
These beans taste even better the next day as the flavors meld together. Store leftovers in an airtight container in the fridge for up to 5 days. They reheat beautifully—just add a splash of water or broth to loosen the sauce. For meal prep, I like to portion them into individual containers so I can grab and go. Freezing isn't recommended since the sauce can get watery, but if you must, freeze for up to 3 months. The bacon fat solidifies when cold, so reheating gently is key to keeping everything tender.

Step-by-step instructions for slow-cooked smoky baked beans
Here's how to create the perfect balance of smoky, sweet, and savory flavors in these rich baked beans.
Cook the Bacon and Prepare Aromatics
Cut the 8 oz thick-cut bacon into ½-inch pieces and place them in a large Dutch oven over medium heat. Cook the bacon for 8-10 minutes, stirring occasionally, until it's crispy and the fat has rendered out. You'll want about 2 tablespoons of bacon fat remaining in the pot—this is your flavor foundation.
Remove the bacon with a slotted spoon and set it aside on paper towels to drain. In the same pot, add the chopped 1 whole yellow onion and cook for 5 minutes until softened. Stir in the 3 minced garlic cloves and cook for another 30 seconds until fragrant. This step builds the aromatic base that carries through the entire dish.
Build the Flavor Base
Reduce the heat to medium-low and add the 2 tablespoons tomato paste, stirring to coat the onions and garlic. Cook for 2 minutes until the raw taste disappears. Then add the 0.5 cup unsweetened molasses, 0.25 cup brown sugar, 1 tablespoon Dijon mustard, 1 tablespoon apple cider vinegar, 0.5 teaspoon ground black pepper, 0.25 teaspoon ground allspice, 0.125 teaspoon ground cloves, and 1 teaspoon salt.
Stir everything together until the molasses and sugar dissolve completely. You'll notice the mixture darken and thicken slightly as the spices bloom. This is when all the flavors start to meld together—don't rush this step. Let it simmer for 3-4 minutes while you prepare the beans.
Add Beans and Liquid
Add the 2 cups unsoaked navy beans to the Dutch oven and stir to coat them evenly with the flavorful mixture. Pour in the 2 cups beef broth and give everything a thorough stir. The beans should be completely submerged in the liquid—if not, add a splash of water to cover them.
Bring the mixture to a gentle boil, then immediately reduce the heat to low. Cover the pot and let it simmer for 1 hour. This initial cooking time allows the beans to begin softening while preventing them from breaking apart. Check occasionally to ensure the beans remain submerged and add more broth if needed.
Slow Cook Until Tender
After the initial hour, uncover the pot and stir in the crispy bacon you set aside earlier. Return the beans to a simmer and cook uncovered for another 2-3 hours, stirring occasionally. You're looking for beans that are fork-tender but still hold their shape—when a bean easily crushes between your fingers, they're ready.
The beans should have a thick, glossy sauce clinging to them, and the aroma should be rich with smoky, sweet, and savory notes. If the sauce gets too thick during cooking, add a splash of water to maintain the proper consistency. The longer they cook, the deeper the flavors develop.
Rest and Serve
Once the beans reach the perfect tenderness, remove the pot from heat and let the beans rest for 15-20 minutes. This resting period allows the flavors to fully meld together and the beans to absorb any remaining liquid. The sauce will thicken slightly as it cools, creating that perfect cling you want on every bite.
Taste and adjust seasoning if needed—you might want to add a pinch more salt or a splash of vinegar to balance the sweetness. Serve the beans warm, topped with additional crispy bacon if desired. These baked beans pair perfectly with cornbread or grilled meats, making them a hearty centerpiece for any meal.
Pro Tips For Making America'S Test Kitchen Boston Baked Beans
- CRISP THE BACON FIRST: DESCRIPTION: Cook the thick-cut bacon until it’s deep brown, not just pink—this adds fat and flavor that’ll carry through the beans. I used to skip this, and the dish always tasted like it needed more depth. Trust me, the extra 5 minutes here makes a real difference.
- SOAK BEANS 8+ HOURS: DESCRIPTION: Dried navy beans need a long soak (overnight works best) to break down starches and shorten cooking time. I learned this the hard way—rushed soaks lead to split beans and gummy texture. Drain and rinse right before using.
- SIMMER LOW AND SLOW: DESCRIPTION: After the initial boil, drop the heat to a gentle simmer—barely bubbling. Too much heat turns the molasses bitter and the beans mushy. I used to walk away and forget, then came back to a sad, syrupy mess.
- BROWN THE ONIONS: DESCRIPTION: Caramelize the onions until they’re golden, not just soft—this builds sweetness that balances the molasses. Skip this, and the dish tastes flat. (Yes, even if you’re impatient like me.)
Perfect pairings for america's test kitchen boston baked beans
Bacon-Crusted Cornbread
This classic Southern pairing takes your beans to the next level. Use a 1-inch thick cornbread loaf with 4 slices crispy bacon crumbled on top. I like to brush the cornbread with 2 tablespoons melted butter and sprinkle with ¼ cup cornmeal before baking at 375°F for 20 minutes.
The smoky-sweet beans cut through the cornbread's crumbly texture beautifully. 🥓
Grilled BBQ Ribs
For a full meal, serve these beans alongside St. Louis-style pork ribs tossed in ½ cup BBQ sauce (I recommend Sweet Baby Ray's Original). Grill the ribs at 275°F for 3 hours, then finish with a 5-minute broil for caramelization.
The smoky, tangy sauce complements the beans' sweetness perfectly.
Crispy Sausage Links
Swap bacon for smoked kielbasa sausages sliced into ½-inch rounds and pan-fried until crispy. I like to add 1 teaspoon smoked paprika to the oil before cooking for extra depth. These sausages add a meaty contrast that balances the beans' richness. Serve with yellow mustard on the side.
Apple-Cider Glaze
Drizzle the beans with a simple apple-cider glaze made by simmering ½ cup apple cider vinegar, 2 tablespoons brown sugar, and 1 teaspoon cinnamon for 5 minutes. This adds a bright, tangy contrast that cuts through the molasses' sweetness. Perfect for holiday meals!
Pickled Red Onions
Quick-pickle 1 red onion sliced thin with ½ cup apple cider vinegar, 1 tablespoon sugar, and ½ teaspoon salt for 30 minutes. The sharp acidity balances the beans' richness and adds a refreshing crunch. I like to scatter them on top before serving.
Cold Beer Pairing
A crisp American lager like Bud Light or Coors Banquet cleanses your palate between bites. For a craft option, try a Belgian witbier like Hoegaarden—its citrus notes complement the molasses beautifully. Avoid heavy IPAs or stouts that might overpower the beans' delicate flavors. 🍺

Frequently asked questions
Why do I need to brown the beans first?
Browning the beans in bacon fat creates a deep, nutty flavor that's essential for authentic taste. This step develops the Maillard reaction, which builds complex caramelized notes that you won't get from simmering alone. Skipping it results in bland, watery beans that lack that signature diner-style richness.
Can I use canned beans instead of dried?
Yes, but with adjustments! Use 2 (15 oz) cans of navy beans, drained and rinsed, and reduce the cooking time to 1.5 hours total. Canned beans are pre-cooked, so they won't need the full simmering time. The texture will be slightly softer, but still delicious when paired with the smoky sauce.
What if my sauce gets too thick or too thin?
For a thick sauce, simmer uncovered for 10-15 minutes longer to reduce. If it's too thin, stir in 1 tbsp cornstarch mixed with 2 tbsp water or add 1/4 cup tomato paste. Never over-salt to fix thinness—balance flavors with acid (vinegar) or sweetness (brown sugar) instead.
How do I make these beans vegetarian?
Swap the bacon for 8 oz smoked tempeh or 6 oz mushrooms (cremini or shiitake) sautéed until crispy. Use vegetable broth instead of beef broth and add 1 tsp liquid smoke to mimic the smoky depth. The molasses and spices will still create that signature flavor profile.
Can I make these in a slow cooker?
Brown the bacon and aromatics first, then transfer everything to your slow cooker. Cook on low for 7-8 hours or high for 4-5 hours, stirring occasionally. The slow cooker's gentle heat enhances the flavors even more, making them perfect for hands-off cooking.
