🥦 How to make pickled cauliflower in the fridge (step-by-step)

1️⃣ Step One: Cut the cauliflower to fit the jar.

The first step to making easy refrigerator pickled cauliflower is to prepare it by washing the heads and cutting off the florets from the stems.

Sustainable cooking tip: Don’t waste those stems! Save your cauliflower stem scraps to use in food scrap vegetable broth. Close the loop on food waste!

2️⃣ Step Two: Prepare the pickling jar

Next, add the cut cauliflower to a tall jar with dill or other herbs, mustard seeds, garlic, and red pepper flakes. You can also add other vegetables to the jar if you’d like, we like adding sliced radish, bell peppers, or even lemon or lemon slices when we have them.

Make sure there is about ½ – 1 inch (2-3 cm) of space above the cauliflower and below the jar’s lid so that the pickling liquid will completely cover the cauliflower so it pickles evenly. Any pieces of vegetable that extend out of the top of the water will not be pickled and could grow mold or other bacteria while storing, so make sure there’s enough space.

3️⃣ Step Three: Prepare and add the brine

Now it’s time to make the brine, or the salted and sugared vinegar water that will work the magic of pickling your cauliflower.

The foundational vegetable pickling brine recipe we use is:

  • 1 cup water
  • 1 cup vinegar (distilled vinegar, white wine vinegar, and apple cider vinegar are our favorites)
  • 1 tablespoon salt
  • 1 tablespoon sugar
a small sauce pan with salt and sugar inside on a white table with a measuring glass of water and a bottle of apple cider vinegar
Add salt, sugar, vinegar, and water to pan

We increase or decrease the amount of brine depending on the amount of vegetables we’re pickling, but this is the general formula we use that always produces pickled veggies with a great taste.

To make the brine, simply add water, a vinegar of your choice (see our recommendations below), salt, and sugar to a medium saucepan and bring to a boil.

Pour the hot brine into the jar and completely cover the cauliflower, then close the lid tightly and let cool completely on the counter until it reaches room temperature (see first photo for example of brine pouring).

Which vinegar should you choose? For the mildest flavor choose distilled white vinegar. For more of a flavor punch try white wine vinegar or apple cider vinegar (our favorite). Malt and balsamic vinegar have the strongest flavor, but we have found the taste of these vinegars is too strong when quick pickling.

4️⃣ Step Four: Refrigerate to quickly pickle the cauliflower

Once the jar of cauliflower is cool, store in the refrigerator and let the cauliflower pickle in the salted vinegar brine.

If you want to serve quickly we recommend letting the cauliflower ferment for at least 2 hours to let it soak up the brine, but for best results and flavor wait at least 24-48 hours. Pickled cauliflower is good for up to one month in the refrigerator.

💡 Recipe questions + quick tips

Should I blanch the cauliflower before pickling?

Blanching, or boiling the cauliflower for a few minutes, before pickling will help it retain its color (if you’re using colored cauliflower). However, we’ve tested pickled cauliflower both ways and have found that the color variation is so slight that it’s not worth this extra step unless you’re very worried about the presentation. The taste is the same, which is the important part!

What jar should I use to quickly pickle cauliflower?

Choose a jar tall enough to store the pickled cauliflower with about ½ – 1 inch of space between the top of the spear and the lid so that the brine liquid can completely submerge the beans. Because cauliflower is a thicker vegetable, we chose jars that were wider to fit in as many as possible.

How long before you can eat pickled cauliflower?

You can eat the pickled cauliflower as soon as 2 hours after pickling, however we suggest waiting a minimum of 24 hours for best results. If your cauliflower florets are small, then less time is needed for good flavor. However, if it is thick then it may need more time to soak before it is fully pickled.

How long does pickled cauliflower last?

Pickled cauliflower lasts up to one month in the refrigerator as long as it is completely covered with the liquid brine. However, if it is sticking out of the water you’ll run the risk of bacterial growth, so make sure to choose a jar that allows the vegetable to be completely submerged in the brine.

Is pickled cauliflower healthy?

Pickled cauliflower is healthy! Per the USDA Food Nutrient Database, one cup of cauliflower has 2 grams of plant-based protein, 2 grams of fiber and is an excellent source of vitamin C and a good source of iron. However, the brine is high in sodium due to the salt needed to pickle the vegetable, so use as a compliment to meals or eat a few cauliflower spears as a snack with a well-balanced diet.

What is the best cauliflower for pickling?

It’s possible to pickle any type of cauliflower: white (attribute or cheddar hybrids), green (romanesco), purple (depurple hybrid), or orange (aptly named cheddar hydrid) — you name it, you can pickle it.

How do I know if my pickled cauliflower has gone bad?

Quick pickling vegetables does not come with the same food safety hazards as traditional pickling and canning. However, to make sure your cauliflower stays safe while stored in the refrigerator make sure to completely cover in the liquid brine and to feel the cauliflower florets before eating. If they’re slimy, throw them out.

👩‍🍳 How to serve pickled cauliflower

Quick pickled vegetables like cauliflower are great additions to salads, bowls, or are even a great simple snack. Here are a few recipes and ideas to get you started:

  • On a large fruit, vegetable, and nut platter. Use quick pickled cauliflower as a pickable vegetable on a large platter with assorted seasonal fruits, vegetables, nuts, seeds, and crackers.
  • Add to a salad or bowl. Top a salad or grain bowl with pickled cauliflower, like this Spicy Peanut Tofu Bowl or on our Leftover Broccoli Stem Salad (add your cauliflower stems too!).
  • Snack on pickled cauliflower florets. Grab a few pickled cauliflower bites and a handful of nuts or seeds for a deliciously salty plant-based snack.

♻️ Sustainable kitchen tips + tricks

While pickling seasonal vegetable is sustainable in itself, there are a few tips and tricks you can learn to make this cauliflower recipe even more environmentally friendly:

Take advantage of cauliflower season! The best time to make fast pickled cauliflower is during the height of cauliflower season. In California that’s actually year round (except July and August), but check out Seasonal Food Guide’s produce seasonality calendar to find when cauliflower are in season near you.

Save large food jars to use for quick pickling. We’re always on the lookout for great jars to keep around the house for pantry and food storage, so keep an eye out for larger jars you can remove the label from and save to use for pickling cauliflower (tip: we used an empty Costco artichokes jar!).

Save the cauliflower stems for soups and broths. Don’t throw out the cut off cauliflower stems, save them to flavor soups and broths like our homemade vegetable broth made from food scraps.
