I usually make these early in the morning and put them in the slow cooker for our afternoon meal. But they can also be made a day or two in advance and baked in the oven covered at 325 for 50-60 minutes.
"It was nice to be able to make this the day before so I didn't have that mess just before trying to serve a meal. I baked them in the oven for an hour before we ate and they were ready to serve just when we were ready to eat. They tasted great too!"
