Begin by soaking your dried beans overnight in plenty of water, or quick soak them by boiling for 1 hour then draining. Drain any soaking water and set aside.
Add the soaked beans to your slow cooker along with water or broth, ensuring they're covered by at least an inch. Stir in the diced bacon, chopped onion, minced garlic, maple syrup, apple cider vinegar, smoked paprika, and season with salt and pepper to taste.
Set the slow cooker to low and cover with the lid, letting the mixture cook gently for about 6 hours, until the beans are tender and the sauce has thickened into a glossy, caramelized coating.
Halfway through, give the beans a gentle stir to promote even cooking and prevent sticking, especially if they start to look dry.
Once cooking is complete, check the seasoning, adding more salt, pepper, or maple syrup if desired, and stir well to combine all flavors.
Serve the beans hot, spooned out of the slow cooker, with a sticky, thick sauce coating each bean and bits of bacon visible on top. Enjoy your rich, smoky-sweet baked beans!
