Ingredients
For the Quick Pickled Red Onions

- 1 ½ TBS sugar or other sweetener
- 1 tsp salt

How to Make Quick Pickled Red Onions
Step 1: Prepare the Onion
Pack the sliced onion into a pint-sized jar tightly. Ensure it is very compact, as this will help ensure there’s enough brine covering all the onions.
Step 2: Make the Brine
- In a saucepan or microwave-safe bowl, combine:
- ½ cup water
- ½ cup vinegar of choice
- 1 ½ TBS sugar
- 1 tsp salt
- Heat the mixture either on the stove or in the microwave until it begins to steam.
- Stir well until both sugar and salt are fully dissolved.
Step 3: Pour Over Onions
Carefully pour the hot brine over the packed onions in the jar until they are fully submerged.
Step 4: Let It Rest
Allow the onions to rest at room temperature for at least 30 minutes if sliced very thinly. For thicker slices, let them sit longer.
Step 5: Refrigerate
After resting, place your pickled onions in the refrigerator. They can be enjoyed after just 30 minutes but will develop deeper flavors over time. Store them for up to three weeks!

Common Mistakes to Avoid
When making Quick Pickled Red Onions, a few common pitfalls can lead to less-than-perfect results. Here are some mistakes to be aware of:
- Overpacking the Jar: If the jar is not tightly packed with onions, you may end up with insufficient brine. Ensure you pack the onions firmly but not too tightly.
- Insufficient Brine: Not using enough liquid can result in uneven pickling. Always ensure that the brine completely covers the onions for the best flavor.
- Skipping the Refrigeration: Allowing pickled onions to sit at room temperature for too long can spoil them. After 30 minutes, refrigerate them to maintain freshness.
- Ignoring Slicing Thickness: Thick onion slices will take longer to pickle. Adjust your chilling time based on how thickly you slice the onions for optimal taste and texture.
- Using Low-Quality Vinegar: The type of vinegar influences the flavor significantly. Opt for a good quality vinegar that complements your dish.
