Pickled Red Onions | Easy Side Dish Recipes

• 1 large red onion, thinly sliced

• 1 cup white vinegar (apple cider vinegar as an alternative)

• 1/2 cup water

• 1 tablespoon sugar (or honey as an alternative)

• 1 1/2 teaspoons salt

• 1/2 teaspoon black peppercorns (optional)

• 1 bay leaf (optional)

• 1-2 garlic cloves, sliced (optional for extra flavor)

• 1 jalapeño, sliced (optional for added heat)

• 1/2 teaspoon dried oregano (use thyme if oregano is unavailable)

1. Prepare the Onions:  Thinly slice the red onion and jalapeño (if using). Place the slices in a heatproof jar or bowl.

2. Make the Brine:  In a small saucepan, combine the vinegar, water, sugar, and salt. Add the black peppercorns, bay leaf, garlic, and dried oregano for extra flavor if desired. Bring the mixture to a simmer over medium heat, stirring until the sugar and salt are dissolved.

3. Pickling:  Pour the hot brine over the sliced onions (and jalapeños), ensuring they are fully submerged. Let the mixture cool to room temperature.

4. Store:  Once cooled, cover the jar or bowl and refrigerate for at least 1 hour before serving. The pickled red onions will develop more flavor the longer they sit and can be stored in the refrigerator for up to 2 weeks.

5. Serve:  Serve the pickled red onions as a tangy, crunchy topping for your birria tacos. The sharpness of the pickled onions will complement the rich, savory meat of the birria, adding a burst of flavor and a delightful crunch.

Bright and Tangy Flavor Contrast

Birria tacos are known for their deep, robust flavors, with meat that’s slow-cooked in a rich, spiced broth until it’s melt-in-your-mouth tender. While this flavor profile is absolutely delicious, it can benefit from a bright and tangy contrast, and that’s exactly where pickled red onions come in. The sharpness of the vinegar combined with the sweetness of the onions creates a refreshing balance that cuts through the richness of the birria, enhancing the overall flavor experience.

Enhancing the Birria Bomb Experience

The term “birria bomb” perfectly encapsulates the explosive flavor combination that occurs when you add pickled red onions to your birria tacos. The tangy onions elevate the tacos by adding layers of flavor and texture. The crunchy, zesty bite of the pickled onions contrasts beautifully with the tender meat, making each bite a complex and satisfying experience. This dynamic pairing transforms a simple taco into something extraordinary, truly worthy of the “birria bomb” moniker.

Recipe Variations for Your Birria Bomb

Add Some Heat

If you like your pickled red onions with a bit of a kick, try adding sliced jalapeños or a pinch of red pepper flakes to the brine. The heat from the peppers will infuse the onions, creating a spicy side dish that’s sure to impress. This variation is perfect for those who love a little extra spice in their tacos.

This variation is particularly delicious when paired with the savory richness of birria meat.

Experiment with Herbs and Spices

Don’t be afraid to experiment with different herbs and spices in your pickled red onions. Try adding a bay leaf, some black peppercorns, or a few sprigs of thyme to the brine for added depth of flavor. These simple additions can transform your pickled onions into something truly unique and elevate your birria bomb to the next level.
