Chopped-up bacon cooked in oil will enhance the flavor of baked beans, especially if you want a barbecue style. Level up the flavor by adding caramelized onions.

However, the caramelization process will take time. If you're in a rush, sauteed onion or onion powder will add extra fragrance, sweetness, and umami to your beans and bacon.

Espresso powder is a great addition to baked beans. Just a pinch will add a rich bold flavor and a slight bitterness to balance the sweetness of the beans.

Add a few teaspoons of chipotle adobo sauce and crumbled chorizo for a Mexican twist to your baked beans, infusing a spicy and smoky flavor.
