Preheat your oven to 350°F (175°C).

In a skillet over medium heat, cook the diced bacon until crisp.

Add the chopped onion to the skillet and cook until softened, about 5 minutes.

In a large mixing bowl, combine the navy beans, cooked bacon, sautéed onion, brown sugar, ketchup, mustard, Worcestershire sauce, salt, pepper, and smoked paprika. Stir well to combine.

Pour the bean mixture into an oven-safe baking dish.

Cover the baking dish with aluminum foil and bake for 1 hour.

After an hour, remove the foil and bake for an additional 30 minutes.

Once done, let the beans cool slightly before serving.
