How to Make Old Fashioned Boston Baked Beans
There are no shortcuts here—but don’t worry, it’s still incredibly simple. With just a little prep and 4 straightforward steps, you’ll have the best Boston baked beans. Start by rinsing and sorting your dried beans, discarding any broken pieces or pebbles, then soak them overnight in a large bowl of cold water. Let’s get cooking!
- Step 1: Cook the Beans. Pour the soaked beans and their soaking liquid into a large pot. Bring to a boil over medium heat, then reduce to a simmer and cook for 1 to 2 hours, or until the beans are tender. Drain the beans and set aside the cooking liquid for later.
- Step 2: Layer the Dish. Lightly grease a 3-quart baking dish with nonstick spray. Add half of the cooked beans in an even layer, then top with half the chopped bacon and half the onions. Repeat with the remaining beans, bacon, and onions.
- Step 3: Make the Sauce. Combine the brown sugar, molasses, ketchup, mustard, Worcestershire sauce, and garlic powder in a medium saucepan or Dutch oven. Stir well, then bring to a gentle boil over medium heat, stirring often until smooth and bubbly.
- Step 4: Pour and Bake. Pour the sauce over the layered beans, then add enough reserved bean liquid to just cover everything. Cover the dish with foil and bake at 325°F for 1½ hours. Remove the foil and bake uncovered for another 1½ to 2 hours, checking every 30 minutes and adding more bean liquid as needed to keep the old fashioned baked beans from drying out.
Serving Suggestions
As a tried-and-true classic, these old fashioned baked beans pair perfectly with just about any dish at any gathering. However you plan to serve them up, here are a few guaranteed ways to make them the star of the spread.
- Build a toppings bar with chopped herbs like cilantro, parsley, chives or green onion, plus sour cream, a shredded cheese or even cooked ground meat, shrimp or sausage for a fully loaded bowl.
- Round out a casual dinner and serve these beans next to BBQ meatloaf, chicken and potato packets, or the crispiest fried chicken.
- Pair with Backyard BBQ favorites like boneless beef ribs, pulled pork sliders, or BBQ chicken nuggets.
Expert Tips
- Soak for Success: Don’t skip the overnight soak—it softens the beans and helps them cook evenly. Short on time? Use the quick soak method: bring beans to a boil, turn off the heat, cover, and let them sit for 1 hour.
- Check the Liquid Content: As the beans bake, keep an eye on the liquid level. Add more reserved bean water as needed to keep them moist and saucy.
- Low and Slow Wins: Stick to the lower temp and longer baking time. It’s what gives these old fashioned baked beans from scratch their classic texture and flavor—totally worth the wait!
- Storing and Reheating: Store leftovers in an airtight container in the fridge for up to 5 days. For longer storage, freeze leftovers in a freezer-safe container for up to 3 months. To reheat, place the beans in a baking dish, cover, and warm at 325°F for about 30 minutes, or until heated through.
- Make Ahead: These New England style baked beans are a great prep-ahead option! Cook them a day in advance, let them cool, and refrigerate until you’re ready to serve. The flavors get even better overnight—and all you have to do is reheat and enjoy.
Recipe FAQs
Yes, in a pinch! Use 3 to 4 cans of navy or great northern beans (drained and rinsed) and reduce the cook time in the oven. You can skip the soaking and long simmer, but note that the flavor and texture won’t be quite as rich as the slow-cooked version.
Definitely! Skip the bacon and add a smoky flavor with a dash of smoked paprika or liquid smoke instead.
If your beans are still tough, they may not have cooked long enough during the simmer stage. Be sure they’re fully tender before assembling the casserole. Also, old beans (over a year old) won’t soften as well, no matter how long they cook.
