Mix all ingredients (except for bacon) in a 4-6 quart slow cooker.
Give the mixture a good stir.
Cover and cook on low for 3-5 hours.
Stir the beans gently a couple of times during cooking.
Right before serving, stir in cooked bacon (if using).
Notes
Please refer to my FAQ’s (Frequently Asked Questions) and ingredient list above for other substitutions or for the answers to the most common questions.
Note: you can add the cooked bacon pieces to the baked beans while they cook. However, we choose to add the cooked bacon at the end so it stays crispy.
