I’ve been really into pickling to preserve food lately. It is one of the oldest forms of food preservation, dating back to ancient Mesopotamia. But while most people today think of pickles as the familiar pickled cucumbers in dill pickles and bread and butter pickles, I’ve been trying my hand at pickling all sorts of foods.

I’ve pickled and canned the all-familiar pickled peppers, but I wanted to expand my pickling knowledge further than just peppers and cucumbers. I hesitantly tried pickled cranberries, and I absolutely loved them. Which, to be honest, was kind of shocking because the combination of pickling brine and cranberries sounded gross.

So, when I found out that pickled brussels sprouts are a thing and that they’re eloquently called frog balls, I had to try them. Personally, I love brussels sprouts and am happy to enjoy them during the holidays while they’re in season. My family, on the other hand, aren’t super big fans.

I figured what the heck, I could try preserving some yummy brussels sprouts by pickling them… and just maybe some of the family will like them. And guess what? They did!

If you’re not a big brussels sprouts fan, pickling them is definitely the way to go, the flavor is so much different than a steamed or boiled sprout on your dinner plate.

How to Make Pickled Brussels Sprouts

Ingredients for pickled brussels sprouts; fresh brussels sprouts, onion, garlic, jalapeno, and spices on a counter.

Prepare jars and canner. Even if you aren’t canning these frog balls, you still need to wash your jars and lids in hot soapy water and heat up the jars for at least 10 minutes to sterilize them. So put them in your canner or a pot of water and bring it to a boil while you prep everything else.

Wash and prep the brussels sprouts. Wash the brussels sprouts, remove the outer leaves and cut off the ends. Then, slice each sprout in half lengthwise.

Blanch the brussels sprouts. Whether you’re canning or not, I’ve found blanching them really helps. It brightens them and if you’re not canning them, it cooks them enough so you can actually eat them, otherwise they’re just too hard.

If canning, place in boiling water for 2 minutes and then immediately submerge them in an ice bath to stop the cooking process. If you’re not canning these, boil them for 3 minutes and then submerge them into the ice bath to stop the cooking process.

Boil the brine. Combine vinegar, water, and canning salt in a large pot and bring it to a boil while you pack the jars with the brussels sprouts.

Pack the jars. Pack brussels sprouts into jars, top with a garlic clove, some diced onion, some diced jalapeno, mustard seed, and peppercorns.

Add the brine. Pour the brine over the brussels sprout mixture leaving half-inch of headspace. Then, run a plastic air bubble remover through the jars to remove air and mix the spices into the jars a little better. Adjust headspace if necessary.

Wipe jar rims, center lids, finger tighten bands.

Process jars in a canner (if desired). Place packed jars in the waiting canner and be sure they’re covered by at least 2″ of water. Place the lid on the canner and bring it to a boil. Process in boiling water for 15 minutes before removing to a towel-lined counter to leave undisturbed for 24 hours before checking seals. Allow the jars to sit one to seven days before enjoying for the best flavor.
