Now, pour the cornbread mix in the crockpot and mix everything together.
Place the crockpot on low for 5-6 hours. This will vary from crockpot to crockpot. The casserole is finished with the center is firm. If you touch it and it doesn’t bounce back, instead it sinks in, you'll need a little more time.
