What to Do With Leftover Corned Beef? 3 Tasty Recipes to Make After St. Paddy’s Day

Leftover corned beef is too yummy to waste after your feast. So, we suggest using this salty and spiced meat to flavor your favorite savory meals. Whether you’re craving a breakfast hash or cheesy quesadilla, corned beef comes in handy for making these dishes more flavorful and filling. The juices from the cooked corned beef also ensure that it stays moist for days once stored correctly. Keep reading for chef’s tips on using leftover corned beef to wake up the flavors of classic breakfast, lunch or snack recipes!

The basics of corned beef

Corned beef is a beef brisket that’s been cured in a brine with salt and spices. The beef sits in the brine for a few days, which tenderizes the meat and infuses it with flavor. Plus, it retains a pink color once cooked thanks to curing salt within the brine. This process results in juicy corned beef that’s delicious, especially enjoyed with tender vegetables like cabbage, potatoes and carrots.

How many days is leftover corned beef good for?

Leftover corned beef can last about 3 to 4 days in the fridge. It’s perfectly fine to enjoy a cold in a sandwich, salad or dip, or you can warm it up in a dish instead.

Chef’s secret to storing corned beef for moist results

It’s best to store the corned beef with any cooking juices as it prevents the meat from drying out. Below, you can find a guide for storing corned beef — shared by chef Claudia Sidoti in our story on how to reheat brisket:

  1. Place sliced corned beef in a sheet of plastic wrap.
  2. Pour some of the meat’s juices over the meat before carefully wrapping the meat. 
  3. Cover the plastic wrap pouch in foil and then place it in a plastic bag.
  4. Keep the meat in the fridge and use within 3 to 4 days for the best flavor and texture.

When you’re ready to enjoy the leftover corned beef, you can chop or shred it before adding it to a variety of recipes.
