how long to cook frozen corned beef in instant pot

Why only cook corned beef once a year? It is so darn delicious and simple in the Instant Pot! Instant Pot Corned Beef and Cabbage is going to be your new go to from here on out!

My house is a weird house. Corned Beef is a staple, not just on St. Patrick’s Day! We love it for some reason. I usually stock up my freezer when they go on sale around St. Patrick’s Day then cook them through out the year. My only complaint about cooking yummy corned beef is how LONG it takes both in the crock pot or on the stove.

With St. Patrick’s Day right around the corner, I figured, what better time to conquer Corned Beef and Cabbage in my love (AKA the Instant Pot)! I refuse to be standing over the stove our hovering over the crock pot!

As with everything that goes along with the Instant Pot, it was a bit of a learning process at first to prefect corned beef and cabbage. I originally threw everything in the pot and cooked it on manual for 45 minutes. As you can imagine, my 2.5 pound corned beef was not done and everything else was just mush.

My second attempt went a little better but was still not up to par. I just looked at these like a learning experience and was able to prefect it the third time around.

Frozen Corned Beef Instant Pot

Since an extra half hour is added I knew the potatoes I once used as trivets would disintegrate. It would be better to make roasted potatoes in air fryer separately. I have made many simple cabbage recipes to pair with this once it’s done but pressure cooker fried cabbage is by far our favorite.

A 3.5 pound corned beef brisket was used for this. Pressure cook timing would be appropriate for a 3-4 lb. size. Don’t throw away the pickling spice packet that comes in the bag, you’ll need that. This is what you’re going to need, it isn’t much;

  • Beef brisket that has not been defrosted + spice packet
  • Beer, broth or combine half with cup of water
  • Adding minced garlic to the top is optional

If you really really wanted to add red potatoes to this I would do it differently than if yours were fresh. Instead of sitting the meat on top, set them on the very top out of the liquid. They will cook slower that way and not fall apart as much.

Full instructions and ingredient amounts listed below in the printable recipe card. There is nutritional information listed there too but I would refer to the back of your package for that since they are all slightly different.

The bigger the fat pad the better flavor your piece will have. That will certainly increase the fat content listed though so you’d need to look at the facts on your specific piece for accuracy.

  • You’re going to start out by placing a trivet with handles inside your pressure cooker. Pour 4 cups of your chosen liquid inside the pot.
  • Set frozen corned beef on trivet. Top with minced garlic and spice packet on top.
  • Close the lid and seal pressure release valve. Set to high pressure for 2 hours cook time.
  • When done allow release the pressure naturally. This will take about 30 minutes, do NOT do a quick release.
  • Open the lid carefully, remove corned beef and slice on a cutting board.

You can make air fryer cabbage in about 15 minutes or follow our Ninja Foodi cabbage recipes to serve on the side. Slow cooker mashed potatoes is another favorite for sure.

If you want to use these instructions to make frozen Ninja foodi corned beef and cabbage that works too. Like I said, it doesn’t matter what brand name yours has on the front of it. I have done it in all 3 different types I have in my pantry. We may have one slice left over at times. I never get rid of it because it saves so well for the next day.

Once it is cooled slide what is left into a baggie. Only slice what you are going to eat because storing a larger piece will keep it very moist. Slide it into a baggie and keep in the fridge until the next day. Either warm it up with some gravy or you can make something wonderful with it.

Of course corned beef hash is an old fashioned favorite and reminds me of being at my Grandmother’s table during the holidays.

Our family favorite is making leftover corned beef soup. It’s kinda’ like a chowder with vegetables and diced potatoes inside. I will tell you it is so amazing that I have cooked this meat just so that I could dice it up and make this soup as a main meal many times! Do you make anything great with it the next day we should try too?

No matter the method you use, it’s best to cook low and slow. Place the corned beef in a stockpot. Add the spice packet and a bottle of dark beer. Bring to a boil, cover, and cook on a low simmer for about 2.5-3.5 hours, or 45-50 minutes per pound.

Can you cook beef from frozen in Instant Pot?

It is safe to cook frozen food in a pressure cooker because it uses pressure to move food through the “Danger Zone” quickly.

How do you adjust the cooking time on frozen meat in an Instant Pot?

Plan for the time to “pressure up” to increase Bargain for at least 10 extra minutes for the pot to come to pressure when using frozen meats. Sometimes up to 40 extra minutes, depending on what you are making.
