Notes
What can I do with beef stew leftovers?
You can either throw the leftovers into a microwave-safe dish and microwave on high for about a minute- increase if you are reheating a lot of stew all at once. Or, you can reheat all of the leftovers by adding them back into your Ninja Foodi and warming on the saute function for a couple of minutes. You can even reheat it using the slow cooker function. You may need to add some additional beef broth to make it less thick. If you'd like, you can freeze the leftover stew. Put the leftover stew in freezer-safe, plastic containers. When ready to eat, thaw and heat. Leftover stew should stay good in the freezer for about 3 months if sealed properly.
What cut of meat should I use to make beef stew?
Beef stew meat is usually made up of chunks of chuck or round roast. My grocery store sells it already cut and packaged. But, you can buy a chuck roast or a round roast and cut it up into small chunks- about 1 or 2 inches in size. Stew meat is never the best cut of meat. It's usually tougher meat that needs some time to cook and becomes more tender.
