Equipment

  • Chef's knife
  • Cutting board
  • Measuring cups & spoons
  • Medium saucepan
  • Mason jar

Ingredients
 

  • 1 large red onion
  • 2 cloves garlic
  • 1 cup white vinegar
  • 1 cup water
  • 2 teaspoons kosher salt
  • 1 ½ tablespoons cane sugar
  • 1 teaspoon whole peppercorns

Additional seasonings optional

  • 1-2 teaspoons Mexican oregano
  • 1 bay leaf
  • 1-2 whole cloves
  • A few Jalapeño slices
  • A pinch of whole cumin seeds
  • A pinch of whole coriander seeds

Instructions
 

  • Peel the onion, then cut it in half, and thinly slice it. Peel and crush the garlic (this will help release the flavor). Set both aside.
  • In a medium saucepan, bring the water, vinegar, salt, and sugar to a gentle boil. Mix in the onion slices, garlic cloves, and whole peppercorns.
  • Turn off the heat and let the saucepan sit covered for 10 minutes. Then, add the onions to a mason jar and pour the pickling liquid over top. Lightly tap the jar down on your counter to remove any air bubbles.
  • Let the jar sit for another 20 minutes, then serve your quick-pickled onions immediately or transfer them to your fridge for storage. Happy eating!

Notes

  • Thinly slice the onions: Making thin slices will result in quicker pickling and a better final texture.
  • Don’t rush the process: Allow the pickled onions enough time to soak up the flavors for the best infusion of flavors.
  • Keep them submerged: Ensure all the onions are fully covered in the pickling liquid so they properly pickle.
  • Jar size: Use a jar that's just the right size to pack the onions in. If it’s too large, they may not stay submerged.
  • Adjust to taste: Feel free to adjust the sugar and salt based on your liking. Some people prefer no sugar, so experiment with it to see what you like best.
  • Use clean jars: Always use clean, sterilized jars to prevent any bacterial growth. Wash them in boiling hot soapy water or the dishwasher beforehand.
  • Tap to remove bubbles: Tapping the jar on the counter ensures all the onions are submerged and there are no air pockets left.
  • Nutritional information is a rough estimate and should not be taken as health advice.
