Pickling is one of those old-fashioned kitchen skills that fits beautifully into a modern low-carb lifestyle. With just a few pantry staples, vinegar, water, and salt you can turn everyday veggies (and even eggs) into tangy, crunchy snacks that brighten up your meals without adding carbs or sugar. The best part? You don’t need a different recipe for every vegetable. One brine works for red onions, cucumbers, gherkins, and even boiled eggs.
Traditional pickle recipes often call for sugar, but the truth is, it’s not essential. In vinegar-based pickling, the vinegar and salt are the real preservatives. Sugar is usually added to balance acidity and soften sharp flavors. For a low-carb or keto diet, you can leave sugar out completely and still have safe, tasty pickles. If you miss that touch of sweetness, a carb-free sweetener works just as well and your pickles will taste just as delicious without the glucose spike.
The Basic Low-Carb Brine
Here’s a no-sugar brine that works for just about anything:
-
1 cup vinegar (white, apple cider, or rice vinegar)
-
1 cup water
-
1 tablespoon salt
-
Spices of choice: garlic, dill, mustard seeds, chili flakes, peppercorns, or bay leaves
If you prefer a touch of sweetness without carbs, add 1–2 teaspoons of sweetener. This makes the pickles tangy with a hint of sweetness. I use erithritol or honey. If you are not on a ketogenic diet, you can use sugar.
How to use it:
-
Bring everything to a boil in a small pot.
-
Pack your veggies (or eggs) into clean jars.
-
Pour the hot brine over them, seal, and let cool.
-
Refrigerate. They’re good to eat after 24 hours, but the flavor gets better after a few days.

Pickling FAQs
1. How long do homemade pickles last?
In the fridge, quick pickles (like these) usually last 2–4 weeks. Always use a clean fork or spoon when removing them from the jar to prevent contamination.
2. Can I reuse the brine?
Yes and no. You can reuse brine once or twice for new veggies, but the flavor will be weaker each time. If you’ve pickled eggs, don’t reuse the brine—it’s best to make a fresh batch.
3. Do pickles need to be refrigerated?
Yes. Since this is a quick-pickle method (not a canned, shelf-stable one), they must be stored in the fridge.
4. What vegetables are best for pickling?
Cucumbers, onions, carrots, radishes, cauliflower, jalapeños, and green beans all work beautifully. For low-carb eating, stick to non-starchy vegetables.
5. Can I make pickles without vinegar?
That would be fermentation, not pickling. Vinegar is what makes these quick pickles tangy and shelf-stable in the fridge.
6. How soon can I eat them?
They’re tasty after about 24 hours, but if you can wait 2–3 days, the flavors really shine.
