How to Make Homemade Pickled Red Onions

Step 1: Prepare the Red Onions

1. Peel the Onions: Remove the outer skin and trim the ends.
2. Slice Thinly: Cut the red onions into thin rings or half-moons. Use a mandoline slicer for consistent thickness.
3. Separate Layers: Gently pull apart the rings to ensure even pickling.
4. Rinse with Cold Water (Optional): To reduce the sharpness of raw onions, rinse them under cold water and pat dry.

Step 2: Make the Pickling Brine

1. Combine Ingredients: In a medium saucepan, add water, vinegar, sugar, and salt.
2. Heat the Mixture: Bring to a gentle boil over medium heat, stirring occasionally until the sugar and salt dissolve completely.
3. Add Flavor Enhancers (Optional): Toss in garlic, peppercorns, or spices if desired for added flavor.
4. Remove from Heat: Allow the brine to cool slightly for a few minutes before pouring over the onions.

Step 3: Combine and Soak

1. Pack the Onions into a Jar: Fill a clean glass jar with the prepared onion slices.
2. Pour in the Brine: Carefully pour the warm pickling liquid over the onions, ensuring they are fully submerged.
3. Remove Air Bubbles: Use a spoon to press the onions down and release trapped air pockets.
4. Let It Cool: Allow the jar to sit uncovered until it reaches room temperature.

Step 4: Store and Refrigerate

1. Seal the Jar: Close the lid tightly to lock in freshness.
2. Refrigerate: Place the jar in the fridge for at least 30 minutes before serving. For best flavor, let it sit overnight.
3. Shake Before Use: Give the jar a quick shake before using to evenly distribute the flavors.

Flavor Variations and Customizations

Sweet and Spicy Variation

For those who love a balance of sweet and heat, try this variation:

• Add 1–2 tablespoons of honey or maple syrup to the brine for natural sweetness.
• Toss in ½ teaspoon red pepper flakes or a sliced jalapeño to add a spicy kick.
• You can also add cinnamon sticks or star anise for a touch of warmth and complexity.

Herb-Infused Option

If you prefer earthy, herbaceous flavors, include:

• Fresh thyme or rosemary sprigs in the jar.
• Bay leaves or dill seeds for a mild herbal aroma.
• Crushed garlic cloves for a savory undertone.

Experiment with these combinations to suit your personal taste or to complement specific dishes!

Common Mistakes to Avoid

1. Skipping the Salt or Sugar: These ingredients balance the acidity of the vinegar and improve flavor.
2. Not Submerging Onions Fully: Ensure onions are completely covered in brine to avoid spoilage.
3. Using a Non-Airtight Container: Always use a tightly sealed glass jar for storage.
4. Overcooking the Brine: Don’t boil the brine for too long—it may alter the flavor profile.
5. Ignoring Cooling Time: Pouring boiling brine over onions can soften them too much, so let it cool slightly before adding.

By avoiding these errors, you’ll create perfectly crisp and flavorful pickled red onions every time.
