It'll have juices in the crock. Drizzle in oil and just enough water to cover. Then take the meat out when it's done and whisk in a little flour or cornstarch and that's gravy!
spices on the meat ?
Salt and pepper, onion and garlic if you have it. We use onion, bell pepper, and celery in all the Cajun foods. They call it the "holy trinity."
