Why You’ll Love This Recipe!
With St. Patrick’s Day around the corner and my need to eat corned beef at least once a year in tribute to my Irish ancestry, I decided to use the Instant Pot to cook it.
Ingredients Needed
- Corned beef brisket with seasoning packet
- Water
- Coleslaw mix. I buy the prepackaged coleslaw mix. You could also use sauerkraut or slice your own cabbage if you prefer
- Red wine vinegar
- Sugar
- Canola oil
- Salt
- Swiss cheese
- Thousand Island Dressing
- Rye bread or sourdough bread
- Butter
- Powdered Parmesan cheese. I use the kind in the round green container!

How to Make Instant Pot Corned Beef
- Place the meat into the instant pot on top of the steam rack that comes with the Instant Pot.
- Add 1 cup of water and sprinkle in the little spice packet that comes in the package.
- Set it the vent to sealing and press “manual” and then set it at 60 minutes at high pressure.
- Do a natural release on it’s own. I love the corned beef straight out of the Instant Pot. It is so tender and flavorful.

How to Make A Reuben Sandwich
- Make your coleslaw mixture by combining coleslaw, vinegar, oil, sugar and salt. Allow to sit for a few minutes for moisture to absorb.
- Toast your bread. You can leave it untoasted but toasting it takes it to the next level!
- Butter each slice of bread on one side.
- Sprinkle with powdered Parmesan Cheese.
- Place under the broiler and broil until it turns golden brown.
- Add corned beef to one slice of prepared bread and top with Swiss cheese. Place under broiler and allow cheese to melt.
- Top with coleslaw and Thousand Island Dressing and other piece of bread.

Any instructions for how to add carrots, potatoes and onion to this if you are doing this as a corned beef with vegetables? I followed this link from your Corned Beef Slow Cooker recipe which adds them in half way through but I am not sure if, or how, you can do this in the IP. Thank you.

Don’t put them in with the corned beef, they will get too mushy. Remove the corned beef when it is done and then add the veggies. Cook them on High Pressure for 3 to 6 minutes with a quick release.
