Ingredients Overview

Each ingredient in this pickled red onion recipe plays a crucial role in creating the perfect balance of tangy, sweet, and savory.

  • Red Onions: Red onions are ideal for pickling because of their mild, slightly sweet flavor and vibrant color. They hold their crunch well during the pickling process.
  • Apple Cider Vinegar: This vinegar adds both tang and a hint of natural sweetness. It’s milder than white vinegar and complements the onions beautifully.
  • Water: Diluting the vinegar ensures the pickling liquid isn’t overly sharp. It also softens the onions without making them too acidic.
  • Sugar: Sugar provides a subtle sweetness that balances out the tang of the vinegar. You can adjust the amount to your preference for more or less sweetness.
  • Salt: Essential for bringing out the natural flavors of the onions and aiding the pickling process. Use kosher salt or sea salt for the best results.
  • Black Peppercorns: These add a gentle spiciness and depth to the pickling brine. You can experiment with different types of peppercorns for varied flavors.
  • Bay Leaves: Bay leaves offer an aromatic, earthy background note that enhances the flavor profile of the onions.

Step-by-Step Cooking Instructions

Follow these simple steps to create deliciously tangy pickled red onions.

Step 1: Prepare the Vinegar Mixture
In a small saucepan, combine the apple cider vinegar, water, sugar, salt, black peppercorns, and bay leaves. Stir the mixture well to dissolve the sugar and salt. Bring the mixture to a gentle simmer over medium heat.

Step 2: Soften the Red Onions
Thinly slice the red onions, ensuring consistent cuts for even pickling. Once the vinegar mixture is simmering, add the sliced onions to the saucepan and let them cook for about 1 minute. You’ll notice the onions will start to soften slightly and take on a beautiful translucent hue.

Step 3: Cool the Onions
Remove the saucepan from the heat and let the onions and brine cool to room temperature. This allows the flavors to infuse without overcooking the onions.

Step 4: Store and Refrigerate
Once cooled, transfer the onions and the brine into a clean, airtight jar. Make sure the onions are fully submerged in the liquid. Seal the jar and refrigerate for at least 2 hours before serving. For the best flavor, let them sit overnight.
