    I love a good slow cooker meal and how you can toss some simple ingredients into the crock with some spices and come out with an amazing dinner! Some of our favorite crockpot meals are Slow Cooker French Dip Sandwiches, Slow Cooker BBQ Chicken, and Slow Cooker Chili Mac.

    How often do you eat corned beef? For us, it’s only once a year, unfortunately. This year I am going to buy a few extra and stash them in the freezer so we can have it a few more times. Or I may just cook it just to make reuben sandwiches. (one of my husbands favorite sandwiches!)

    What is corned beef made of?

    Corned beef is a beef brisket that soaks in brine and then cures with salt and seasonings. The term comes from using large grains or “corns” of salt.

    Corned beef comes in multiple cuts, and it’s always best to cook corned beef for a long period of time so that it becomes tender. Typical cooking methods include boiling, slow cooking or oven roasting the meat.

    How to cook corned beef to make it tender:

    I know a lot of people don’t cook corned beef because it’s too tough. Well, the solution to that problem is it needs to cook longer. So here a few tips on how to cook corned beef.

    Low and slow: This is the ONLY way to cook corned beef. Brisket is a very tough cut of meat and the only way to get tender beef is the low and slow method. That’s why I prefer my handy dandy slow cooker for corned beef.

    Time: It takes a long time to get tender brisket. I always end up leaving mine in the crockpot for 10 hours. If you are making corned beef and it’s still tough it needs to cook longer.

    Rest: All cuts of meat need to rest after they are done cooking. This allows the juices to redistribute through the meat. This is crucial for juicy meat. Allow to rest for at least 10-15 minutes before slicing.

    Carving: Another tip for tender corned beef is to cut across the grain. Brisket has long fibrous strands and by cutting across the grain it makes them much shorter and more tender.

    • 1 (3½ pound) (1.5kg) corned beef brisket
    • 2 pounds (1kg) Yukon gold potatoes (or whatever you have on hand) scrubbed well and cut into large chunks
    • 20 baby carrots
    • 1 (12 oz) (355ml) Guinness stout (or can use about 2 cups beef broth)
    • ¼ cup (50g) packed brown sugar
    • Seasoning packet that came with corned beef
    • 1 small head of cabbage
    1. Trim the corned beef of all visible fat if desired. Place in the bottom of the slow cooker. Sprinkle with brown sugar and seasoning packet. Pour Guinness around the corned beef then place the potatoes and carrots around the corned beef. Cover and cook on low 8-10 hours. NO PEEKING! I don't recommend cooking on high.

    2. Remove outer leaves from cabbage and cut into 4 wedges. Place in crock pot around the beef. Return lid and cook for 20 minutes. This will give you tender crisp cabbage. If you like softer cabbage put in earlier.
    Recipe Notes
    1. This corned beef and veggies cooks for a long time and so the potatoes and carrots will be quite soft. If you prefer your potatoes and carrots not so soft add them half way through cooking even though the recipe says no peeking. 
    2. The reason not to peek is because everytime the lid is removed from the slow cooker it adds an extra 30 minutes to the cooking time. It’s so tempting to lift the lid and check the meat while cooking but try no to.
