What to do with Leftover Sauerkraut

Why is opening up a small can of sauerkraut like opening up a huge can of WhoopAss? It’s like the stuff expands as soon as the air hits it!

If you’re a fan of sauerkraut, you know that it’s not always easy to finish a whole jar or can any time soon. But don’t worry, there’s a simple solution! In this post, I’ll show you how to store and freeze portions of leftover sauerkraut, so you can enjoy it for weeks or even months to come. So let’s get started!

What to do with leftover sauerkraut

So when you find that there is far too much to use, freeze the extra in an ice cube tray!

You can usually find ice cube trays at the dollar store.

When the sauerkraut is frozen, pop the cubes into a freezer bag and label the bag with a Sharpie so you remember what it is.

Just microwave one or two cubes for 60 seconds, and they are perfect for a Reuben or a hotdog!

An alternative method

If you can’t find an ice cube tray, and are an avid InstantPot user, perhaps you have one of those silicone egg bite molds handy? I love having more than one use for stuff like that, so it’s a great alternative to the ice cube tray. It even comes with a handy, tight-fitting lid, so you won’t risk spills in the freezer – or any smell!

Label everything!

I always label everything that goes into the freezer because there was that one time when I didn’t.

I was leading a craft workshop for kids, and we were making paper in one of the lessons. At the end of the lesson, I put the leftover paper pulp into a plastic tub and stuck it in the freezer to use for the next group.

I had also used a container just like it containing frozen and (unlabeled) mashed potatoes.

Guess who grabbed a container out of the freezer in the morning before work, and thawed out a tub of paper pulp for dinner?

Lesson. Learned.
