This is my all time favorite way to cook corned beef and cabbage. Corned beef brisket and cabbage cooked in a Guinness spiked broth until the meat is so tender it falls apart and the cabbage is soft and buttery.
Right before serving, glaze the brisket with brown sugar mustard sauce & serve with creamy parsley buttered potatoes.
This recipe includes instructions for making Corned Beef and Cabbage in your Slow Cooker or in your Instant Pot.
Rather watch than read? Here's a short video tutorial that will show you how to make Corned Beef and Cabbage in the Instant Pot.
Corned beef and cabbage originated in Ireland as a traditional Easter Sunday dinner, a tradition that, I understand, has waned considerably over the past couple of decades. At least in Ireland. Here in the US, many of us consider it mandatory fare on St. Patrick's day.
This recipe is just about as simple as you can get. But it also includes a couple of not-so-traditional elements:
- Dijon mustard brown sugar glaze
- Parsley buttered potatoes that are cooked separately from the corned beef and cabbage
How to Make Corned Beef and Cabbage in an Instant Pot
Cooking corned beef and cabbage in an Instant Pot only takes about 90 minutes, start to finish.
About an hour and a half before you want to eat, remove the brisket from the package, reserving the pickled spice packet. Rinse the meat under cold water then pat dry with paper towels.
Peel an onion and cut it into 8 wedges. Set the wedges in the bowl of an Instant Pot and lay the corned beef brisket on top.
Remove the brisket from the package, reserving the pickles spice packet. Rinse the meat under cold water, pat it dry with paper towels, and lay it in the Instant Pot over the onions.
Add the pickled seasoning, brown sugar, and Guinness to the pot and cook on high pressure for about an hour and a half.
Remove the corned beef from the Instant Pot, strain the liquid and pour about 1 ½ cups back into the bowl of the Instant Pot. Cut a head of cabbage into 8 wedges and add them to the IP along with some baby carrots. Cook on high pressure for 4 minutes.
Spread the mustard sauce over the cooked corned beef brisket and set it under the broiler for 2-3 minutes, until the sauce begins to brown in spots.
Place the mustard-covered brisket on a serving platter and arrange the cooked cabbage and carrots around it. Serve with parsley buttered potatoes.
Slow Cooker Instructions
I love using a slow cooker on those days on which I know I won't have any time to mess with dinner later in the day.
- In the morning, remove the brisket from the package, reserving the pickled spice packet. Rinse the meat under cold water and pat it dry with paper towels.
- Peel an onion and slice it into 8 wedges onion wedges. Place the wedge in the bowl of a slow cooker and lay the corned beef brisket on top. Sprinkle the pickled seasoning plus 3 tablespoons of brown sugar over the brisket.
- Pour two bottles of Guinness over the meat. (You can use water, chicken or beef broth instead of Guinness if you prefer.)
- Set the slow cooker to cook the brisket on high for 4 hours or on low for 6 hours.
- Nestle the cabbage and carrots into the slow cooker along with the brisket and sprinkle them with a bit of salt. Cook for another 2 hours on high or 4 hours on low.
3 Ingredient Mustard Glaze
A few years ago, a friend of mine served corned beef for dinner that had been coated with a delicious slightly sweet mustard glaze. It was sooooo good that it forever changed the way I make this dish.
You only need 3 ingredients and 3 easy steps to make this tangy mustard sauce:
- Mix a bit of dijon mustard with salt and brown sugar
- Brush the glaze over corned beef brisket after the brisket is done cooking
- Place the glazed brisket under the broiler for a couple of minutes, just until the glaze is beginning to brown in a few places
For such simple thing, that mustard glaze is heaven on the salty, tender corned beef.
How to Make Parsley Buttered Potatoes
Most corned beef and cabbage recipes include potatoes that have been boiled in the same pot as the corned beef and cabbage. This is not my favorite way to cook them.
Boiled potatoes have the tendency to become overcooked and water logged to the point that they just fall completely apart on your fork. Plus, boiled potatoes are kinda bland.
Mushy and bland. We can do better than that.
Instead, I like to cook the potatoes separately from corned beef using a simple method of boiling them for only a few minutes, then finishing them in a skillet with butter and parsley.
This results in potatoes that are meltingly tender on the inside, buttery, salty, and slightly crisp on the outside. They are the antithesis of mushy and bland, each bite creamy, crispy, and flavorful.
Here's how to make them:
Add the potatoes to a medium or large saucepan and add enough water to cover the potatoes by 2 or 3 inches. Stir in 3 tablespoons of salt and s the pan over high heat. When the water begins to boil, cook the potatoes for 5-8 minutes, until just barely fork tender. Remove the potatoes from the water.
Add some butter and oil to a large skillet and set it over medium heat. When the butter has melted, add the potatoes.
Sprinkle the potatoes with another teaspoon of salt and roll them around in the pan so that they are coated on all sides in butter and oil.
Cover the pan and turn the heat down to low. Let the potatoes cook for 20 - 25 minutes. Every once in a while, shake the pan so the potatoes roll around and do not burn.
The potatoes are done when a fork pricked into one of the potatoes slides in like butter.
Remove the pan from the heat and add the chopped parsley. Stir the potatoes around in the pan to coat in the butter and parsley, then turn them out into a serving bowl.
How to Use Leftover Corned Beef and Cabbage
- Corned Beef Hash is a delicious way to transform leftover Corned Beef and potatoes into the kind of casual comfort food that will turn anyone into a leftover lover.
- The classic Reuben Sandwich is made with toasted slices of dark rye bread packed with corned beef, sauerkraut, Swiss cheese and tangy homemade Russian dressing. This sandwich is the perfect reason to make extra corned beef and cabbage on St. Patrick's Day.
