Description
These quick pickled red onions are tangy, slightly sweet, and crisp—perfect for adding flavor and color to salads, tacos, sandwiches, and more. Made with simple ingredients in just minutes, they’re a fridge staple.
Ingredients
- 2 medium red onions, thinly sliced
- 1 1/4 cups water
- 1 1/4 cups white vinegar
- 3 tablespoons sugar
- 1 tablespoon sea salt
- 1/4 to 1/2 teaspoon red pepper flakes (optional)
Instructions
- Heat the water in a small saucepan until hot but not boiling, then remove from heat.
- Thinly slice the red onions and place them in a clean glass jar.
- Add sugar, salt, vinegar, and red pepper flakes (if using) to the warm water and stir until fully dissolved.
- Pour the brine over the onions in the jar, pressing them down so they are fully submerged.
- Seal the jar, let it cool slightly, then refrigerate.
- Let the onions sit for at least 30 minutes before using. For best flavor, refrigerate overnight.
Notes
- For added flavor, try adding whole spices like peppercorns, mustard seeds, or bay leaves.
- Use sliced chili for extra heat instead of red pepper flakes.
- Adjust sugar and vinegar to taste for a milder or sweeter brine.
- Use a clean glass jar with a tight-fitting lid for storage.
- No need to reheat—enjoy cold or at room temperature.
