Drain the soaked beans and rinse them under cold water, then transfer to the crockpot along with water or broth, ensuring they are submerged.
Add the chopped onion and minced garlic to the crockpot, spreading them evenly over the beans.
Pour in the maple syrup and sprinkle the smoked paprika, salt, and black pepper over the beans, allowing the flavors to layer.
Pour the water or broth into the crockpot until the beans are fully covered, typically about four cups.
Cover the crockpot with its lid and set it to low heat, allowing the beans to cook gently overnight or for about 8 hours until they are tender and glossy.
Once cooking is complete, lift the lid and observe a thickened, glossy sauce coating the tender beans, with a rich aroma of maple and smoky spices filling the air.
Use a ladle to gently stir the beans, ensuring the sauce is well coated and thickened to your desired consistency.
Serve the slow-cooked maple baked beans hot, garnished with additional chopped herbs if desired, for a hearty and sweet-savory dish.
