What is Corned Beef
Corned beef is beef that has been cured or preserved with salt. Potassium nitrate or sodium nitrite gives commercially made corned beef its long-lasting pink color. We all know from our high school science class that nitrates and nitrites are forms of salt.
Ingredient Notes and Substitutions
See the complete list of ingredients below on the recipe card.
- Corned beef: Purchase one with a spice packet. Don’t skip the spice packet. It is full of peppercorns, mustard seeds, coriander seeds, anise seeds, and crushed bay leaves, which gives the corned beef its extra delicious flavor.
- Beef broth: preferably low sodium because corned beef is cured with salt.
- Potatoes: Small red potatoes are traditional. Baby yellow potatoes work well, too, because they are waxy like red potatoes. Don’t use russet potatoes. They are not waxy, and they break down during the cooking process.
- Cabbage: Standard green cabbage is the way to go here.
How to Make Slow Cooker Corned Beef
This is the summary version; see the recipe card below for the complete list of ingredients and the instructions.
Unwrap the corned Beef and place it in a slow cooker, fat side up. Sprinkle the spice packet over the top of the corned Beef. Pour the beef broth into the slow cooker over and around the corned Beef. Cover and cook on low for 5 hours.
Add the onions, carrots, and potatoes. Cover and cook on low for 1 hour. Add the cabbage, cover, and cook on low for 2 hours.
Preparations Tips
- Leave the fat on the corned beef when simmering, as it helps cook it tender and gives it lots of flavor. For this method, cook it fat side up.
- For aesthetic purposes, peel your carrots. You will appreciate the bright orange color.
- Once cooked, trim the fat from the beef. I like to leave a very small portion of fat on for more flavor, but my husband likes it trimmed completely.
- Slice the corned beef against the grain, producing the most tender pieces that do not fall apart.
Flat Cut or Point Cut
Don’t let these two different cuts confuse you. Corned beef, after all, is simply beef brisket cured in a salt brine. The brisket is then split into two cuts: the flat and the point cut. The flat cut is much leaner, but it still has a thick layer of fat, so it cooks up moist and tender. It is best for slicing and is my first pick for traditional corned beef.
The point cut gets its name from coming to a point at one end. It is marbled with more fat and connective tissue. This cut cooks up tender and juicy but is best used for shredding.
Storage and Reheat
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the microwave at 50% power for 1 minute increments until warm. You can freeze the corned beef, potatoes, and carrots for up to 2 months, but I do not recommend freezing the cabbage.

I’m always unsure about the liquid the corned beef is packed in – should it be rinsed off or added with the beef?
Beth Pierce
I discard any liquid left in the wrapper but I do not rinse it. Some of my readers do!

Using the slow-cooker is a great idea for St. Patrick’s Day! Since everything is cooked together in one pot this is such a time saver and frees up a lot of space on the stovetop. Will definitely need to try this…Looks perfect!
