Equipment

• Chef’s knife — ensures clean, uniform slices for optimal liquid absorption.
• Mandoline slicer — delivers paper-thin, professional-grade slices with minimal effort.
• Glass mason jar — provides a non-reactive, airtight container that prevents flavor leaching and keeps the pickle fresh.

Ingredients

• 1 large red onion, peeled and thinly sliced (approx. 2 cups sliced)
• 1 cup apple cider vinegar (or white distilled vinegar)
• 1 cup warm water
• 1.5 tablespoons sea salt (or kosher salt)
• 1 tablespoon sweetener of choice (optional, e.g., monk fruit or erythritol for a zero-carb option, or honey)
• 1 clove garlic, smashed (optional for extra aroma)
• 1/2 teaspoon whole black peppercorns (optional)

Instructions

1. Prep the Onions: Using a sharp chef’s knife or a mandoline, carefully slice the red onion as thinly as possible. Pack the slices tightly into a clean glass mason jar or airtight container.
2. Mix the Brine: In a medium bowl or measuring cup, combine the warm water, apple cider vinegar, sea salt, and sweetener. Whisk vigorously until the salt and sweetener are completely dissolved.
3. Combine and Steep: Pour the vinegar brine over the sliced onions in the jar, ensuring the onions are completely submerged. Add the smashed garlic clove and black peppercorns if desired.
4. Rest and Chill: Let the jar sit uncovered at room temperature for 30 minutes to allow the flavors to meld and the onions to soften. Secure the lid tightly and transfer to the refrigerator; they are ready to enjoy after 30 minutes, but taste even better after a few hours.
