How to Make Pickled Red Onions

Step 1: Prepare the onions

Peel and thinly slice the red onions into even rings or half-moons, depending on your desired presentation. Using a sharp knife or mandoline makes this step easier and more consistent, ensuring even pickling.

Step 2: Make the pickling brine

Combine apple cider vinegar, water, sugar (natural), salt, and your choice of natural spices in a small saucepan. Heat gently until the sugar and salt fully dissolve, creating a fragrant, balanced brine.

Step 3: Pack and pour

Place the sliced onions tightly in a clean jar or glass container. Pour the warm brine over the onions, making sure they are completely submerged. Press down gently to eliminate any air pockets.

Step 4: Cool and refrigerate

Allow the container to cool to room temperature before sealing with a lid. Refrigerate for at least 30 minutes to develop that signature tangy flavor, although overnight is best for a deeper taste.

Pro Tips for Making Pickled Red Onions

• Use fresh onions: Fresh, firm onions result in crispier, more flavorful pickles.
• Slice uniformly: Consistent thickness ensures even pickling and presentation.
• Warm brine helps: Dissolving sugar and salt in warm liquid activates flavors quickly.
• Let it rest: For the best taste, refrigerate overnight before serving.
• Keep submerged: Ensure onions stay covered in liquid to prevent spoilage and maintain crunch.

How to Serve Pickled Red Onions

Garnishes

Pickled Red Onions add a bright, acidic lift as a garnish to grilled vegetables, avocado toast, or buddha bowls. Their vivid pink color makes dishes look as good as they taste.

Make Ahead and Storage

Storing Leftovers

Pickled Red Onions store wonderfully in the refrigerator in an airtight container or glass jar. They will stay crisp and flavorful for up to two weeks, making them a perfect prep-ahead condiment.

Freezing

Although freezing is possible, it may change the texture and soften the onions, so it’s best to enjoy them fresh refrigerated for optimal crunch and tang.
