Ingredients for baked bean recipe for 100

Ten pounds of beans, crispy bacon, and a blend of spices that'll feed 100 hungry guests.

The beans are the star, so pick navy beans—they hold up best to long cooking. Costco or bulk bins are your best bet for 10 lbs at once. If you can't find navy, Great Northern beans work too, but soak them overnight. The bacon? Thick-cut from Costco gives you the best flavor and texture—cook it in batches until crispy, then chop it fine so every bite has those perfect crunchy bits. Onions are non-negotiable here—yellow onions from Trader Joe's stay sweet and caramelize beautifully. For the spices, Penzeys or bulk bins ensure you're getting fresh, flavorful mustard and pepper.

No molasses? Substitute maple syrup at the same amount, though it won't be quite as deep. Short on ketchup? Tomato sauce works in a pinch, but add an extra tablespoon of vinegar for tang. The tomato paste can be Trader Joe's squeeze tubes if you're prepping ahead—no waste, and they keep for months. Want to make this vegetarian? Swap the bacon for smoked turkey bacon or crispy chickpeas (roast chickpeas with smoked paprika). The broth? Low-sodium is key—you'll be adding plenty of salt later. If you're using a slow cooker, reduce the salt by half since the beans will absorb less liquid.

This recipe is designed to be made ahead—prep everything the night before and let it simmer while you handle other dishes. The beans keep 5-6 days in the fridge or 6 months frozen. For serving, I like to portion into slow cookers or chafing dishes so people can help themselves. The bacon bits crisp up again when reheated, so cover with foil loosely if you're keeping it warm. Leftovers? Freeze in gallon-sized bags—perfect for quick meals later. Trust me, you'll want to make extra.

Step-by-step instructions for slow-cooked baked beans

This method delivers rich, smoky, sweet-savory beans perfect for crowds—every step ensures maximum flavor and texture.

In a large Dutch oven or stockpot, heat the 0.5 cup vegetable oil over medium heat. Add the 10 lbs thick-cut bacon in batches to avoid crowding, cooking until golden and crispy (about 10-12 minutes). Use tongs to transfer the bacon to paper towels to drain, then chop it finely.

In the same pot, add the 15 whole yellow onions that have been diced small. Cook them for 8-10 minutes until softened and starting to caramelize—this builds deep flavor. You'll know they're ready when they're translucent with just a hint of golden color. Keep the onions in the pot; they'll form the base of your bean mixture.

Stir in the 2 cups tomato paste and cook for 2 minutes to deepen its flavor. Then add the 1 cup molasses, 4 cups ketchup, and 4 cups brown sugar, stirring until fully combined. This sweet-savory blend is the heart of classic baked beans.

Pour in the 4 cups beef broth and bring the mixture to a gentle boil. Let it simmer for 5 minutes to help the sugars and spices meld together. Here's the thing—this step reduces the liquid slightly and intensifies the flavors before adding the beans. You'll see the mixture darken and thicken a bit, which is exactly what you want.

Add the 10 lbs sorted and rinsed navy beans to the pot along with the 2 cups salt, 0.5 cup ground black pepper, 0.25 cup dried mustard, and 10 whole bay leaves. Stir everything together, making sure the beans are well-coated in the flavorful liquid.

Pour in the 0.5 cup apple cider vinegar and give it one final stir. The vinegar adds a bright tang that balances all the sweetness. Bring the mixture to a boil again, then reduce the heat to low and cover partially. This is where the magic happens—simmer for 2-3 hours, stirring occasionally, until the beans are tender but still hold their shape.

After the initial 2-3 hours of simmering, check the beans for doneness. They should be fork-tender but not mushy. If they're not quite there, continue simmering for another 30-60 minutes, stirring occasionally to prevent sticking. The liquid should reduce to a thick, glossy sauce that coats the beans beautifully.

Real talk: this is the moment that matters. The beans need to absorb all that smoky, sweet, savory goodness. If the mixture gets too thick, add a splash of water or broth to loosen it. The final texture should be like a thick stew—rich but still spoonable. Taste and adjust seasoning if needed, adding more salt or pepper as necessary.

Once the beans are perfectly tender and the sauce has thickened to your liking, remove the bay leaves and give everything one final stir. Ladle the beans into a large serving dish or directly onto a platter. The beans should be glossy and coated in that irresistible sauce, with crispy bacon bits scattered throughout.

Serve immediately while still warm. These baked beans are perfect for potlucks, barbecues, or any gathering where you want to impress a crowd. The combination of smoky bacon, sweet molasses, and tangy vinegar creates a flavor profile that's hard to resist. Store any leftovers in the refrigerator for up to 5 days, though I doubt there'll be any left!
