Storing Leftovers

One thing we love about pot roast night, is leftovers. The beef stores really well. The vegetables will be a little softer the next time you go to reheat, but they will still taste really well.

Store your roast and vegetables in the fridge for a few days. I always make sure to add in some of the broth to help prevent the roast from drying out.

Can You Freeze Leftover Roast

You can freeze leftover roast. The biggest thing is freezing just the meat. The vegetables would break down too much once they thaw out from being frozen.

You can reheat in the microwave or even on the stovetop. I have saved back leftover meat and it is pretty tasty reheated.
