Slow Cooker Cabbage Casserole is one of the easiest casseroles you could ever make. Four ingredients, & you can leave one or two of them out if you want.
1lbground beefcooked and drained
1jar spaghetti sauce of your choice
Additional seasonings: saltpepper, herbs, garlic powder, etc to taste (I didn't add any additional)
In 4-6 quart slow cooker, place 1/2 of cabbage. Top with 1/2 of onions, 1/2 of beef, and 1/2 of spaghetti sauce. Repeat once more. Pour water around the sides into the slow cooker (To keep from disturbing the spaghetti sauce)
Cover and place on low 7-8 hours or high, 3-4 hours.
Serve on it's own or over rice.
NOTE: How well seasoned your casserole is going to be depends on how well seasoned your sauce is. Once it is done cooking you can have a taste and then add more herbs or spices if you like. Or add them at the start if you prefer.
