Ingredients You’ll Need

Here’s what you need to whip up a jar of these zingy onions:

• Red Onions: Look for firm, vibrant onions. They pickle beautifully and their natural sweetness shines through.
• Vinegar: White vinegar gives a clean, sharp flavor. Apple cider vinegar adds a touch of fruitiness if you prefer a milder tang.
• Water: Helps mellow out the vinegar’s bite without compromising the acidity needed for pickling.
• Sugar: Adds a hint of sweetness to balance the sharp vinegar. Feel free to adjust to taste or use honey for a natural option.
• Salt: Essential for flavor and helps break down the onion’s bite.
• Garlic (optional): Adds a savory depth that rounds out the flavor beautifully.
• Peppercorns or Red Pepper Flakes: Optional, but a few add-ins give your pickles a warm, spicy kick.

Variations

Looking to switch things up? Here are some tasty ways to make this recipe your own:

• Use Different Vinegars: Try red wine vinegar for a deeper color and flavor, or rice vinegar for a lighter, slightly sweet finish.
• Add Herbs: Toss in sprigs of thyme, oregano, or dill for an herby twist.
• Go Spicy: Add sliced jalapeños or a dash of chili flakes for some heat.
• Add Citrus: A few slices of lemon or orange peel bring a bright citrusy edge.

How to Make Easy Pickled Red Onions

Step 1: Slice the Onions

Peel and thinly slice the red onions. Thinner slices mean faster pickling and better texture, so aim for ⅛-inch or thinner.

Step 2: Make the Brine

In a small saucepan, combine vinegar, water, sugar, and salt. Heat over medium just until the sugar and salt dissolve—no need to boil. If using garlic or spices, toss them in now.

Step 3: Pack the Jar

Place the sliced onions in a clean jar or container. Pour the warm brine over the onions until fully submerged.

Step 4: Let Them Pickle

Let the onions cool at room temperature, then cover and refrigerate. They’re delicious after 30 minutes but best after a few hours.

Pro Tips for Making the Recipe

• Use a Mandoline: For ultra-thin, even slices that pickle quickly and evenly.
• Sterilize Your Jar: If you want them to last longer, pour boiling water into the jar first, then empty it out before using.
• Press Down Onions: If they float, gently press them down with a spoon to keep them submerged in the brine.
• Double the Batch: Trust me, one jar won’t last long—make extra!

How to Serve

These pickled onions are the ultimate finishing touch. Here are some top ways to enjoy them:

Tacos:

Add to tacos for a tangy crunch—especially good with grilled meats or fish.

Sandwiches:

Layer into burgers, wraps, or grilled cheese for a pop of brightness.

Salads and Bowls:

Scatter over grain bowls or leafy salads to liven things up instantly.

Breakfast:

Toss on avocado toast or scrambled eggs for a surprising zing.

Make Ahead and Storage

Storing Leftovers

Keep them in a tightly sealed jar in the refrigerator. They stay crisp and flavorful for up to 3 weeks.

Freezing

Not recommended—freezing changes the texture and dulls the flavor.

Reheating

No need to reheat—these are served cold or at room temperature, straight from the jar.

FAQs

Can I use white or yellow onions instead?
You can, but red onions are preferred for their natural sweetness and stunning pink hue after pickling. Other onions will still pickle, but the flavor and color won’t be quite the same.

Do I have to heat the brine?
Yes, a quick warm-up helps dissolve the sugar and salt and kickstarts the pickling process. Just warm, not boiling.

How long until the pickled onions are ready to eat?
They’re lightly pickled in as little as 30 minutes, but the flavor gets better after a few hours. For best results, let them chill overnight.

Can I reuse the brine?
You can reuse it once, but the flavor will be milder. Always use fresh onions and store in the fridge.
