How to Make Homemade Sauerkraut

I’ve been really into making my own homemade keto-friendly sauerkraut lately (it goes perfectly with this Reuben casserole). If you’d like to try your hand at making some yourself, here is the exact recipe that I use:

  • Prepare the cabbage. Slice your cabbage into quarters and remove the cores. Then slice each quarter lengthwise to make 8 wedges. Finally, slice each wedge crosswise into ribbons.
  • Season. Combine the cabbage ribbons with salt in a large bowl. Use your hands to thoroughly mix the cabbage and salt together for 5-10 minutes; long enough for the cabbage to become watery and limp.
  • (Optional) Add seeds. Add in caraway seeds if desired.
  • Pack. Pack your cabbage mixture into a mason jar. Then use a smaller weighted jelly jar to press the cabbage down; this will help to keep it submerged under the liquids.
  • Press. For the next 24 hours, you’ll want to press down on the cabbage with the jelly jar periodically.
  • Ferment. Keep the sauerkraut at a cool room temperature and allow it to ferment for between 3-10 days.

How to Store Keto Reuben Casserole Leftovers

You can keep your keto Reuben casserole leftovers stored in either the fridge or the freezer.

Before storing it, you’ll first want to make sure that the casserole has cooled off completely once it comes out of the oven. You can then either leave it in the baking dish and wrap it tightly with plastic wrap, or simply transfer it into an airtight storage container.

You’ll be able to keep your leftovers stored like this in the fridge for up to 3 days or you can alternatively freeze it for up to 3 months.
