RECIPE TIPS
How to Serve Corned Beef and Cabbage
Remove the cabbage, the carrots, and the potatoes from the dutch oven and arrange them individually on a large platter.
Pull out the corned beef carefully with tongs and a large fork or spatula. The meat will be very tender to you don't want it to fall apart.
Let the meat rest for about 10 minutes on a cutting board and then slice across the grain.
You can use a stick blender to puree the onions into the remaining cooking liquid that is in the dutch oven. You can add in a few tablespoons of horseradish sauce or whole grain mustard and serve this gravy alongside the corned beef for extra flavor.
How To Make Slow Cooker Corned Beef and Cabbage
Follow the steps above through browning the corned beef.
Add the onions to the slow cooker.
Place the Corned beef on top.
Add the beef and/or broth.
Set the slow cooker to high for 3 to 4 hours or low for 6 to 7 hours.
About halfway through the cooking time add the carrots, potatoes, and cabbage. (you can add everything at the very beginning, but I feel like the vegetables get really overcooked)
Cook the vegetables for about 2 hours on high or 3 to 3.5 hours on low.
