Ingredients

For the Quick Pickled Red Onions

1 large red onion, sliced (about 2 cups)
1 pint jar
½ cup water
½ cup vinegar of choice (I used white distilled vinegar)
1 ½ TBS sugar or other sweetener
1 tsp salt

How to Make Quick Pickled Red Onions

Step 1: Pack the Jar

Begin by tightly packing the sliced red onion into your pint-sized jar. Make sure it’s packed well; otherwise, you may not have enough brine to cover all the onions.

Step 2: Prepare the Brine

In a separate bowl or pot, combine the following ingredients:
1. Measure out ½ cup water.
2. Add ½ cup vinegar of choice.
3. Include 1 ½ TBS sugar or other sweetener.
4. Stir in 1 tsp salt.

Heat this mixture on the stove or in the microwave until the sugar and salt have completely dissolved.

Step 3: Pour Over Onions

Carefully pour the prepared brine over the packed onions in the jar. Ensure that all slices are submerged in the brine.

Step 4: Let Them Sit

Allow the onions to sit at room temperature for a minimum of 30 minutes if they’re thinly sliced. For thicker slices, let them rest longer.

Step 5: Refrigerate

After resting, place your pickled onions in the refrigerator. They can be enjoyed right away but will taste even better after a few hours. Store them for up to three weeks!

Common Mistakes to Avoid

When making Quick Pickled Red Onions, it’s easy to make some common errors that can affect the flavor and texture. Here are a few mistakes to watch out for:

Not packing tightly – If you don’t pack the onions tightly into the jar, there may not be enough brine to cover them fully. Make sure to press down as you fill the jar.
Ignoring slicing thickness – Slicing the onions too thick can lead to uneven pickling. For best results, aim for very thin slices so they absorb the brine properly.
Skipping the resting time – Allowing the onions to rest for at least 30 minutes is crucial for developing flavor. Don’t rush this step; longer is even better!
Using warm brine immediately – Pouring hot brine over the onions without letting it cool can result in mushy textures. Allow your brine to cool slightly before pouring.
Improper storage – Not refrigerating your pickled onions after they’re made can lead to spoilage. Always store them in the fridge in an airtight container.

Refrigerator Storage
