How to Make Pack Sliced Onions into a Jar

Now that we have our ingredients ready, let’s get started on this delightful journey of packing sliced onions into a jar. Follow these simple steps, and you’ll have a jar of pickled goodness in no time!

Step 1: Slice the Onions

First things first, grab your sharp knife and cutting board. Slice the onions thinly, about a quarter-inch thick. The thinner the slices, the quicker they’ll pickle. I like to cut them into half-moons for a beautiful presentation. Just be careful with those fingers!

Step 2: Prepare the Brine

In a medium bowl, mix together one cup of vinegar, one cup of water, and a tablespoon of salt. Stir until the salt dissolves completely. This brine is the magic potion that transforms ordinary onions into zesty pickled onions. You can even taste it—just a little! Adjust the salt if you like it saltier.

Step 3: Pack the Jar

Now, it’s time to pack those sliced onions into a clean jar. I prefer using a wide-mouth jar for easy packing. Tightly layer the onions, pressing them down gently as you go. This helps to maximize the flavor infusion. If you’re feeling adventurous, toss in some spices between the layers for an extra flavor boost!

Step 4: Add the Brine

Once your jar is packed, pour the prepared brine over the onions. Make sure they are fully submerged. If they float, you can use a small weight or a clean piece of parchment paper to keep them down. This ensures every slice gets that delicious pickling treatment.

Step 5: Seal and Refrigerate

Seal the jar tightly with a lid. Place it in the refrigerator, where the cool air will work its magic. The onions will start to pickle right away, but patience is key! You’ll want to let them sit for at least 24 hours for the best flavor.

Step 6: Marinate for Flavor

After a day of marinating, your pickled onions will be ready to shine! The longer they sit, the more flavorful they become. I often find myself sneaking a taste before they’re fully ready. These vibrant onions will add a delightful crunch and tang to your meals. Enjoy!

Tips for Success

Use fresh, firm onions for the best crunch and flavor.
Experiment with different vinegars for unique taste profiles.
Let the onions marinate longer for a bolder flavor.
Store the jar in the back of the fridge to keep it cold and fresh.
Label your jar with the date to track freshness.

Equipment Needed

Sharp Knife: A good chef’s knife makes slicing onions a breeze.

Cutting Board: Use a sturdy board to keep your workspace safe.
Mixing Bowl: Any medium bowl will do for mixing the brine.
Jar: A wide-mouth glass jar is ideal, but any clean jar works.

Lid: Ensure you have a tight-sealing lid to keep the onions fresh.

Variations

Spicy Kick: Add sliced jalapeños or red pepper flakes to the jar for a fiery twist.
Herb Infusion: Toss in fresh herbs like dill or thyme for a fragrant touch.

Sweet and Tangy: Use apple cider vinegar and add a tablespoon of sugar for a sweeter profile.
Garlic Lovers: Include whole garlic cloves in the jar for an aromatic flavor boost.
Low-Sodium Option: Reduce the salt or use a salt substitute for a healthier version.

Serving Suggestions

Top your favorite tacos with pickled onions for a zesty crunch.
Add them to salads for a pop of color and flavor.
Serve alongside grilled meats for a refreshing contrast.
Pair with sandwiches to elevate your lunch game.
Enjoy as a tangy snack straight from the jar!
