Quick Pickled Kohlrabi (Easy Refrigerator Recipe)

Kohlrabi might be the best vegetable you can pickle. It’s dense enough to stay crunchy for weeks, mild enough to absorb whatever flavors you put in the brine, and firm enough to slice into perfect, uniform pieces that look great in a jar.

Unlike cucumbers, which can turn soft and floppy within days, pickled kohlrabi holds its crunch. Unlike pickled radishes, which can develop an overpowering sulfurous bite, kohlrabi stays clean and bright. And the process takes about 10 minutes of active work.

This recipe uses the quick refrigerator method — no canning equipment, no boiling water bath, no waiting for weeks. You’ll have crisp, tangy, ready-to-eat pickled kohlrabi in as little as 2 hours (though overnight is better).

Basic Quick Pickled Kohlrabi

Ingredients

• 2 medium kohlrabi (about 1 pound total), peeled and cut into 1/4-inch rounds, half-moons, or matchsticks
• 1 cup white vinegar or rice vinegar
• 1 cup water
• 2 tablespoons granulated sugar
• 1 tablespoon kosher salt
• 2 cloves garlic, lightly smashed
• 1 teaspoon whole black peppercorns
• 1 bay leaf

Equipment

• 1 quart mason jar (or two pint jars)
• Small saucepan

Instructions

Step 1: Prep the kohlrabi.

Peel the kohlrabi and cut it into your preferred shape. Thinner cuts pickle faster; thicker cuts stay crunchier longer. Here’s a rough guide:

• Matchsticks (1/8-inch) — ready in 2 hours, best eaten within a week
• Thin rounds (1/4-inch) — ready in 4–6 hours, stay crunchy for 2–3 weeks
• Half-moons (1/4-inch) — ready overnight, crunchy for 3–4 weeks
• Spears or wedges — ready in 24 hours, crunchy for up to a month

Step 2: Make the brine.

Combine vinegar, water, sugar, and salt in a small saucepan. Heat over medium heat, stirring, until the sugar and salt dissolve completely. This takes about 3 minutes. You don’t need to bring it to a full boil — just hot enough to dissolve the solids.

Step 3: Pack the jar.

Place garlic, peppercorns, and bay leaf at the bottom of your jar. Pack the kohlrabi pieces in tightly — they’ll shrink slightly as they pickle, so don’t worry about cramming them in.

Step 4: Pour and cool.

Pour the hot brine over the kohlrabi, making sure all pieces are fully submerged. If any float above the brine, push them down with a fork or use a small piece of parchment paper as a weight.

Let the jar cool to room temperature on the counter (about 30–45 minutes), then seal and refrigerate.

Step 5: Wait.

• Minimum: 2 hours for thin cuts
• Best flavor: Overnight (12–24 hours)
• Peak: 2–5 days (the flavor deepens and the crunch stays)

Five Flavor Variations

The basic recipe is clean and versatile. But kohlrabi’s neutral flavor makes it a blank canvas for bolder pickles. Here are five variations — just add the extra ingredients to the jar before pouring the brine.

1. Spicy Chili-Garlic Pickled Kohlrabi

Add to the basic recipe:

• 1 teaspoon red pepper flakes
• 2 additional garlic cloves, sliced
• 1 small fresno or Thai chili, sliced into rings

The heat builds gradually. After 24 hours, these are mildly spicy. After 3 days, they have a real kick. Excellent on tacos, banh mi sandwiches, and grain bowls.

2. Asian-Style Rice Vinegar Pickles

Replace the white vinegar with unseasoned rice vinegar and modify:

• 1 tablespoon soy sauce
• 1 teaspoon sesame oil (added after the brine cools)
• 1 teaspoon fresh ginger, thinly sliced
• 1/2 teaspoon sesame seeds

Lighter, more delicate, and slightly sweet. Perfect alongside sushi, ramen, or rice dishes.

3. Dill and Mustard Seed Pickles

Add to the basic recipe:

• 3–4 sprigs fresh dill (or 1 teaspoon dried dill)
• 1 teaspoon yellow mustard seeds
• 1/2 teaspoon celery seed

This is the classic deli pickle flavor profile. These taste like kohlrabi wanted to be a cucumber pickle all along. Serve on sandwiches, burgers, or alongside bratwurst for a German-themed plate.

4. Turmeric and Ginger Pickles

Add to the basic recipe:

• 1 teaspoon ground turmeric (or 1 tablespoon fresh, sliced)
• 1 tablespoon fresh ginger, thinly sliced
• 1/2 teaspoon cumin seeds
• 1/4 teaspoon ground coriander

These turn a vivid golden-yellow and have a warm, earthy flavor. Great in Indian-inspired meals, with curry, or on a cheese board for color contrast.

5. Sweet and Tangy Beet-Dyed Pickles

Modify the basic recipe:

• Increase sugar to 3 tablespoons
• Replace 1/4 cup water with beet juice
• Add 1 star anise
• Add 3 whole cloves

The beet juice dyes the kohlrabi a stunning magenta-pink while adding subtle earthiness. The star anise gives a faint licorice undertone. These are show-stoppers on a relish tray or charcuterie board.

How Long Do Pickled Kohlrabi Last?

Quick refrigerator pickles are not shelf-stable — they must stay refrigerated. Here’s the timeline:

Storage method	Shelf life
Refrigerator (sealed jar)	3–4 weeks
Refrigerator (opened, pieces removed)	2–3 weeks
Canned (proper water bath method)	6–12 months

Signs they’ve gone bad: cloudiness in the brine (beyond normal slight haze), off smells, slimy texture on the kohlrabi, or mold on the surface. When in doubt, discard.

For longer-term preservation, kohlrabi also works beautifully as a fermented sauerkraut-style pickle, which uses salt and time rather than vinegar.

Troubleshooting

My pickles are soft, not crunchy.

Most likely cause: the kohlrabi was overripe. Larger kohlrabi (over 4 inches in diameter) can have a woody or spongy core that doesn’t pickle well. Use small to medium bulbs — 2 to 3 inches across.

Also check that the brine wasn’t boiling when you poured it. A rolling boil partially cooks the kohlrabi and softens it. The brine should be hot enough to dissolve sugar and salt, but not at a full boil.

My pickles taste flat.

Add more salt. Under-salted pickles taste one-dimensional. You can also add a splash of additional vinegar directly to the jar. Taste after 30 minutes and adjust.

The brine looks cloudy.

A slight haze is normal, especially with garlic and spices. Significant cloudiness in the first few days could indicate fermentation has started (which isn’t dangerous but changes the flavor). If it smells fine and there’s no mold, it’s safe to eat.

Can I reuse the brine?

Yes, once. The second batch won’t be as flavorful or as crunchy, and the brine loses acidity with each use. Never reuse brine more than once.

How to Serve Pickled Kohlrabi

Pickled kohlrabi is more versatile than you might expect. Here are the best uses:

On sandwiches and burgers. Use thin rounds or matchsticks the same way you’d use pickled cucumbers. The crunch and acidity cut through rich, fatty meats.

On tacos and banh mi. The spicy chili-garlic variation is especially good here. Pile on generously — the acid balances out the richness of pork, chicken, or fried fish.

On a cheese or charcuterie board. Pickled kohlrabi adds crunch and brightness between bites of cheese and cured meat. The turmeric or beet-dyed versions add visual pop.

In grain bowls. A handful of pickled kohlrabi matchsticks on top of a rice bowl elevates the whole thing. The acid and crunch break up the monotony of soft grains.

As a snack. Straight from the jar. No explanation needed.

As a side with grilled meats. German and Eastern European traditions pair pickled vegetables with sausages and grilled pork. Kohlrabi fits right in.

Quick Pickles vs. Fermented Pickles

This recipe uses vinegar for acidity — it’s a quick pickle. The kohlrabi is preserved by the acid in the brine, not by fermentation.

Fermented pickles use salt alone (no vinegar). Beneficial bacteria produce lactic acid over days or weeks, creating a tangier, funkier, more complex flavor. Fermented pickles also contain probiotics.

Both methods work great with kohlrabi. If you want to try the fermentation route, our kohlrabi fermented sauerkraut guide covers the process in detail.

Quick pickles are faster and more predictable. Fermented pickles are more flavorful and have health benefits. Neither is better — they’re different products for different purposes.

Final Tips

• Use a mandoline for uniform thickness. Even slicing means even pickling.
• Don’t skip the garlic. Even in the flavor variations, garlic in the base brine adds depth.
• Make a double batch. These disappear faster than you’d expect, and the effort is the same.
• Label your jars with the date and variation. After a week in the fridge, all pickles look the same.
• Start with the basic recipe before trying variations. Once you know what plain pickled kohlrabi tastes like, you’ll have a better sense of which flavor direction to go next.

Pickled kohlrabi is one of those recipes that’s almost embarrassingly simple but makes you look like you know what you’re doing in the kitchen. Ten minutes of work, a jar, some vinegar, and you’ve got a condiment that improves almost everything it touches.
