Step by Step Instructions

Step 1: Prepare the onions

Peel and slice the red onions thinly and evenly. Uniform slices ensure even pickling. Separate the layers gently to maximize surface area and allow the pickling liquid to penetrate each slice.

Step 2: Make the pickling liquid

In a small saucepan, combine vinegar, water, sugar, salt, black peppercorns, and optional bay leaf or red pepper flakes. Heat gently until sugar and salt dissolve completely, but do not boil. Remove from heat and allow to cool slightly.

Step 3: Pack onions into a jar

Place the sliced onions and optional jalapenos into a clean glass jar or airtight container. Add lime zest if using. Press down lightly to remove air pockets. The onions should be compact but not crushed.

Step 4: Pour pickling liquid over onions

Pour the warm pickling liquid over the onions, making sure they are fully submerged. Cover with a lid and allow to cool to room temperature. Once cooled, place in the refrigerator.

Step 5: Let flavors develop

Quick pickled red onions are ready in about 30 minutes. For deeper flavor, refrigerate for several hours or overnight. The onions will become more tender and flavorful over time.

Step 6: Use or store

Use immediately for recipes using red onions, tacos, sandwiches, or Mexican cooking. For pickled red onions canning, follow proper sterilization procedures to store longer.

How to Serve

Serve pickled red onions as a topping on tacos, burritos, grilled meats, and salads. They add crunch and tang to roasted vegetables, sandwiches, and veggie dishes.

Combine with lime juice for a fresh, bright garnish, or add jalapenos for a spicier touch. They also complement Mexican salsa recipes and Hispanic food dishes perfectly. For presentation, layer the onions in a small dish or jar, adding a few peppercorns or slices of jalapeno on top. Sprinkle with fresh herbs for color contrast if desired.

Additional Tips

Use thin, uniform slices for even pickling
Warm liquid helps onions absorb flavor faster
Do not overcrowd the jar to allow proper pickling
Store in the refrigerator for safety and longevity
Shake or stir occasionally to distribute flavors
Avoid prolonged boiling to maintain crisp texture
For authentic flavor, add optional Mexican spices like cumin seeds

Following these small steps ensures your pickled red onions are crisp, tangy, and flavorful every time.

Recipe Variations
