Ingredients for Quick-Pickled Cucumbers and Onions

Core Ingredients

Here’s what you’ll need to make a small batch that delivers big on flavor:

• Cucumbers – Four medium-sized ones, sliced thin. English cucumbers or Persian cucumbers work best for their thin skin and crisp texture.

• Onion – One small onion, thinly sliced. Red or white both work well.

• White vinegar – The main tang factor.

• Water – Helps balance out the sharpness of the vinegar.

• Sugar – Just enough to add a gentle sweetness.

• Salt – For flavor and preservation.

• Black pepper and garlic powder – Basic pantry spices that build depth.

• Red pepper flakes (optional) – For a hint of heat.

• Fresh dill (optional) – Adds freshness and a classic deli pickle vibe.

This combination brings together sweet, sour, salty, and spicy in a way that’s satisfying and adaptable.

Substitutions and Tips

You don’t need to follow this recipe to the letter—make it your own!

• Vinegar swaps: Try apple cider vinegar for a fruity note or rice vinegar for a softer tang.

• Sweetness tweaks: Like it sweeter? Bump the sugar to 3 tablespoons.

• Onion choices: Red onions add color and a slightly milder bite; yellow onions bring more pungency.

• No dill? No problem. You can skip it or toss in other herbs like tarragon or basil.

The beauty of this recipe is its flexibility. Taste and adjust the brine as you go—you’re in control.

Best Cucumbers for Quick Pickling

Not all cucumbers are created equal, especially when it comes to quick pickling. Here’s what to look for:

• English cucumbers: Long, seedless, and thin-skinned—these are ideal for a crunch that holds up in the brine.

• Persian cucumbers: Slightly shorter but just as crunchy, and a great option if you like smaller slices.

• Avoid waxed cucumbers: Their coating prevents the brine from fully soaking in.

Whichever you choose, be sure to slice them evenly. A mandoline works wonders here, but a sharp knife and a steady hand will do just fine.

Kitchen Tools You’ll Need

Must-Have Tools

You don’t need anything fancy to whip these up. Just:

• A sharp knife (or mandoline) for thin, even slicing

• A mixing bowl to combine your cucumbers and onions

• A saucepan for heating the brine

• Mason jars or any airtight container for chilling and storing

Nice-to-Have Tools

These aren’t required, but they can make things easier:

• A vegetable peeler if you want to remove cucumber skin (though it’s totally optional)

• A jar funnel to avoid brine spills

• A garlic press if you decide to use fresh garlic instead of powder

Keeping it simple is the name of the game—but a few helpful tools can streamline the process and make clean-up easier.

How to Make Quick-Pickled Cucumbers and Onions

You’ve got your ingredients ready and your tools lined up—now let’s bring it all together. This process is simple, satisfying, and a little bit addictive once you see how quickly these pickles come to life. Follow these steps, and you’ll have a batch of crisp, tangy pickles chilling in the fridge before you know it.

Step 1: Prep the Vegetables

Start by slicing your cucumbers and onion as thinly and evenly as possible. A mandoline works beautifully for this, but a sharp knife does the job too. The goal is to keep the slices uniform so they pickle at the same rate.

Place the sliced cucumbers and onions in a large mixing bowl. Toss them gently with your hands to separate any pieces that might be sticking together. This ensures that the brine can coat every slice evenly later.

Tip: If you’re using regular garden cucumbers with thicker skin, you might want to peel them for a softer texture.

Step 2: Make the Brine

In a small saucepan over medium heat, combine the vinegar, water, sugar, salt, black pepper, garlic powder, and red pepper flakes (if using). Stir until the sugar and salt are fully dissolved. This usually takes just a couple of minutes.

Important: Do not let the mixture come to a boil. A gentle heat is all you need. Boiling can alter the balance of the vinegar and weaken the crispness of your vegetables.

Taste the brine at this stage—it should be bright, tangy, slightly sweet, and just a little salty. Adjust the sugar or spice if needed.

Step 3: Combine and Cool

Carefully pour the hot brine over the bowl of cucumbers and onions. Stir everything together to make sure all the slices are coated in that flavorful liquid. You’ll notice the vegetables starting to soften just slightly—this is when the magic begins.

Let the mixture cool down to room temperature. You don’t want to rush this step—adding hot vegetables to the fridge can affect texture and slow down the pickling process.

Step 4: Chill and Marinate

Once the mixture has cooled, transfer everything into clean jars or containers with tight-fitting lids. Pour any remaining brine over the top, making sure the vegetables are fully submerged.

Seal the jars and pop them into the refrigerator. While they’ll start to taste pickled in just a few hours, the flavors really develop overnight.

Pro tip: Give the jars a gentle shake or stir after a few hours to redistribute the brine.

Step 5: Serve and Garnish

When you’re ready to enjoy them, simply open a jar and pull out a few slices. They’ll be crisp, tangy, and infused with just the right amount of seasoning.

Sprinkle with fresh chopped dill before serving if you want that extra burst of herby brightness.

Serve chilled and watch how quickly they disappear—from sandwiches to tacos to straight from the jar.

Tips for Success

Even a recipe this simple has its little secrets. Here are a few tips to make your quick pickles turn out just right every time:

• Use the right cucumbers: Thin-skinned varieties like English or Persian stay crisp longer.

• Slice evenly: Whether you go thick or thin, consistency ensures even pickling.

• Don’t skip the cooling: Pouring hot brine into jars too quickly can soften the veggies too much.

• Adjust to taste: This recipe is super forgiving—taste the brine and make it your own.

• Keep them submerged: Press veggies down or add a weight if needed to keep everything under the brine.

How to Store Quick-Pickled Cucumbers and Onions

At Room Temperature

These pickles are not shelf-stable, so leave them out only long enough to cool. Once they’ve hit room temperature, straight to the fridge they go.

In the Refrigerator

Store your pickles in the fridge in tightly sealed jars or containers. They’ll keep well for about 1 to 2 weeks, though they’re likely to be eaten long before that.

Each day, the flavors deepen a little more, and the texture stays nice and crisp if properly stored.

Freezing Tips

Unfortunately, these aren’t the kind of pickles that like the freezer. Freezing changes the texture of cucumbers, making them mushy when thawed. Stick to the fridge for this one.

Frequently Asked Questions (FAQs)

How long do these quick pickles last?

Stored in the fridge, they’ll stay crisp and flavorful for up to two weeks. After that, they may soften a bit but are still safe to eat.

Can I use other vegetables?

Absolutely. This method works beautifully with carrots, radishes, jalapeños, or even green beans. Just keep the slicing consistent and the total veggie amount close to the original recipe.

Do I need to sterilize my jars?

Not for refrigerator pickling. Just make sure they’re clean and dry—hot soapy water is enough. Sterilization is only needed for canning and long-term shelf storage.

Can I reuse the brine?

You can reuse the brine once, ideally with a fresh batch of vegetables within a few days. Reheat it first and strain out any old bits for best results.
