Line the bottom of the crockpot with the above vegetables
Add 4 cups of water
Mix together all the spices
Rub both sides of the corned beef with the spices and place on top of the vegetables
Cover and cook in the crockpot for 7 hours on low
Discard the top layer of the cabbage, wash, and quarter (I did this ahead of time and had it in the fridge ready for later)
Place the cabbage in the crockpot and cook for an additional 1 hour on low
Plate and serve!
Notes
You can adjust the vegetables to your desired audience. If people are eating hardcore keto, don't serve them the carrots or onions. If you're eating with non keto people, add potatoes but don't eat them yourself.
