Ingredients You’ll Need

- Pork and beans in tomato sauce: Four 15-ounce cans, with one drained, create a hearty bean base that is saucy and satisfying.
- Worcestershire sauce: One and a half teaspoons bring a subtle deep umami complexity that elevates the beans.
- Brown sugar: One-third cup provides the perfect caramel undertone to balance the savoriness.

- Unsulphured molasses: Half a cup lends a rich, molasses sweetness that thickens and glazes the sauce.
How to Make Baked Beans with Bacon and Sweet Onion Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F. Grease a 9×13-inch baking dish with nonstick cooking spray to ensure your beans won’t stick during that gentle baking process. This sets the stage for a delicious, easy cleanup finish.
Step 2: Cook the Bacon
Add the bacon pieces to a cold nonstick skillet and cook over medium heat. You want to render some of the fat and soften the bacon, but don’t crisp it fully yet; those last minutes in the oven will make it perfectly crispy. Set the bacon aside once it’s halfway cooked, and keep the rendered fat in the pan for the onions—this is flavor gold!
Step 3: Sauté the Sweet Onion
Into that flavorful bacon fat, toss in your diced sweet onion. Cook gently for about 5 to 7 minutes until the onions become tender and translucent, releasing their natural sweetness that will meld beautifully with the beans.
Step 4: Combine the Ingredients
Pour the softened onions, pork and beans, Worcestershire sauce, brown sugar, dry mustard powder, and molasses into the greased baking dish. Stir everything together thoroughly so the beans are evenly coated with the rich, sweet, tangy mixture.
Step 5: Assemble and Bake
Scatter the partially cooked bacon pieces on top of the beans, creating a crispy layer of smoky goodness. Bake the dish uncovered for 45 minutes or until the sauce is bubbly and the bacon crisps up perfectly. Your kitchen will start to smell absolutely amazing at this point.
How to Serve Baked Beans with Bacon and Sweet Onion Recipe

Garnishes
Elevate your baked beans with fresh garnishes like chopped parsley or sliced green onions. A sprinkle of freshly ground black pepper can add subtle warmth, and a dash of smoked paprika offers an extra smoky layer for those who love bold flavors.
Side Dishes
This dish pairs wonderfully with classic BBQ fare—think grilled sausages, tender ribs, or smoky pulled pork. For a lighter balance, a crisp green salad or coleslaw adds a refreshing crunch. Don’t forget some crusty bread to scoop up every last bit of the luscious sauce.
Creative Ways to Present
For parties, serve the baked beans in individual ramekins topped with crispy bacon crumbles and a touch of grated cheddar. You can also use the beans as a hearty filling for stuffed baked potatoes or mix them into a warm grain bowl for a comforting, protein-packed meal.
Make Ahead and Storage
Storing Leftovers
Leftover baked beans keep beautifully in an airtight container in the refrigerator for up to 4 days. The flavors often deepen overnight, making the second serving just as delicious as the first.
Freezing
If you want to save the beans for longer, transfer them to a freezer-safe container and freeze for up to 3 months. Make sure to cool completely before freezing to preserve the texture and flavor.
Reheating
Reheat gently on the stovetop over low heat, stirring occasionally to prevent sticking. You can also microwave leftovers in a covered dish, stirring midway through heating to ensure it warms evenly without drying out.
FAQs
Can I use other types of beans for this recipe?
Absolutely! While pork and beans in tomato sauce work perfectly, you could experiment with navy beans, great northern beans, or even a mix of your favorites. Just make sure they are cooked or canned beans to maintain the right texture.
Is it possible to make this recipe vegetarian?
Yes, you can omit the bacon and use smoked paprika or liquid smoke to add that smoky flavor. You can also sauté the onions in olive oil instead of bacon fat to keep it vegetarian-friendly.
Can I prepare the baked beans ahead of time and bake later?
Yes! Mix all the ingredients except the bacon, cover the dish, and refrigerate for up to 24 hours. Just add the bacon on top before baking to ensure it crisps up nicely.
How thick should the baked beans sauce be?
The sauce should be thick enough to coat the beans generously but still a bit saucy and bubbly after baking. If it seems too liquidy before baking, adding a little more brown sugar or molasses can help thicken it.
What’s the best way to cook bacon for this recipe?
Cooking bacon slowly in a cold skillet allows the fat to render out gently, providing flavor to the onions while keeping the bacon tender. Finish crisping up in the oven to get that perfect texture without burning.
