It has always amazed me in cooking how you can use the same ingredients and depending on what you do with them you can have wildly different results. This recipe is the perfect example of that! Take the simple onion and jalapeno which I use in almost all my recipes. Add it to a little vinegar, salt, and sugar and you have a wonderful soft but flavorful addition to any sandwich and more! The quick pickling on the onion and jalapeno soften the texture of the vegetables but also take away the sharp bite of each, leaving you with something amazing! Plus, it only takes a few minutes of active time so you’ll be making this all the time!

This method works with all sorts of veggies you might want to try this on. It’s really up to you and you’re favorite sandwich toppings. Just make sure that you are slicing your vegetables thinly (I like to use a mandoline for this for both ease and uniformity) and that you are storing any leftovers in an airtight container once it cools. Enjoy!

Quick Pickled Red Onion and Jalapenos

Prep Time: 5 minutes
Cook Time: 12 minutes
Total Time: 17 minutes
Course: Miscellaneous
Servings: 5
Calories: 31kcal


  • 1 cup white vinegar
  • 1 cup water
  • 3 cloves garlic peeled and crushed
  • 1 tbsp salt
  • 1 tbsp sugar
  • 3 oz red onion about ½ onion
  • 2 oz jalapeno about 2 medium peppers


  • Using a mandoline or knife, slice peppers and onions thinly. For the peppers, you can choose to keep or remove the seeds. Keeping the seeds will add more heat to the end result.
  • In a small sauce pan, combine vinegar, water, garlic, salt, and sugar and bring to a soft boil. Add jalapenos and onions, stir once, and remove from heat. Let sit for about 12 minutes in the hot liquid.
  • Use on sandwiches, subs, hot dogs, tacos, quesadillas, and more! If you have any leftovers, let the onions and peppers cool and store in an airtight container with the liquid. Enjoy!
