What is Corned Beef?

This term refers to beef brisket that has been cured in a salt solution. This brining process helps break down the tougher cut of meat as well as preserve it.

Many people think of corned beef and cabbage as a classic St. Patrick’s Day meal, but this tradition actually started in America. Back in Ireland in the 1800s, beef was more expensive, so the Irish would eat pork products like bacon or ham to celebrate St. Paddy’s Day.

When the Irish began immigrating to America, however, corned beef was often less expensive than pork. The Irish Americans started eating it for St. Patrick’s Day instead, and that’s how the tradition came to us today!

How to Cut Corned Beef

You always want to cut corned beef against the grain. When slicing, look for the thin lines of muscle fiber running through the meat, then slice perpendicular to them.

Cutting against the grain shortens the muscle fibers, which will make the meat easier to chew. Thinner slices will also be more tender than thicker ones.

What to Serve with Corned Beef

• Irish Soda Bread with no Buttermilk
• Air Fryer Baby Potatoes
• Air Fryer Sweet and Spicy Brussels Sprouts
• Best Air Fryer Green Tomatoes
• Instant Pot Glazed Carrots (or Air Fryer Carrots)
• Instant Pot Mashed Potatoes

How Do You Know When a Corned Beef is Done?

Corned beef should be cooked to at least a medium level of doneness, which means you want the internal temperature to reach 145 degrees F minimum.

However, cooking it longer will help make the meat more tender. I like to cook mine for 1 hour and 45 minutes in the air fryer.

How to Store Leftover Air Fryer Corned Beef

If you have any extra corned beef brisket, store it in a shallow airtight container in the refrigerator. The meat should be eaten within three or four days. 

I love cooking with corned beef leftovers. I recommend serving with eggs and potatoes for a delicious breakfast hash, or you can stack a few slices on rye bread with sauerkraut and Russian dressing for a traditional Reuben sandwich!

Can You Make Corned Beef in a Ninja Foodi Instead?

Absolutely! To make Ninja Foodi corned beef, follow the same instructions listed above, but use your Ninja Foodi on the air crisp function.

I’ve made corned beef and even cornish hen in both my Ninja Foodi and my Cosori basket air fryer and both have cooked perfectly with the directions included!
