About This Recipe
The first time I had Mexican pickled onions was as a topping for fish tacos at a local, now sadly defunct popular Denver Mexican restaurant, Chama. Created by my favorite local restauranteur and Chef, Sean Yontz.
I thought they were the best thing since sliced bread. His fish tacos topped with these beautiful onions were a revelation for my taste buds.
After receiving instructions from the restaurant, I have duplicated Yontz’s recipe. I simply don’t think I’ve had better pickled red onions.
The best way to use these is a superb topping for Tacos. Pickled onions for tacos is simply a must.
But scoop a heaping spoonful onto enchiladas, tostadas or even a hearty serving of pinto beans and you’ve got yourself a new flavor experience.
Tart and sweet, add a hot bite from the onions, some heat from a dried red pepper and these onions bring the Fiesta to any Mexican meal.
So easy and with so much impact. You’ll simply not believe that you’ve never made them before.
Ingredients You’ll Need
Mise en place. Always gather ingredients before starting any recipe. It will save you time and organize your mind.
- Sugar: The sweetness will balance the tart and sour flavor of the vinegar.
- White Vinegar: White vinegar is the most versatile of vinegars. It brings acidity and a tart flavor to this pickled red onion recipe.
- Red Onion: (purple onion) Sweetness is the red onion’s claim to fame. It’s sharp in flavor, and has a higher sugar content that other onions. Plus, we want that red color to add to the vibrance of the finished product.
- Allspice Berries: Allspice is the dried berry of the tropical Pimenta dioica tree native to the West Indies and Central America. Its flavor is a combination of clove, cinnamon, and nutmeg. It brings beautiful aromatics to the finished dish.
- Whole Cloves: Strong, pungent, sweet and almost hot, cloves bring a penetrating flavor to these Mexican pickled red onions.
- Bay Leaf: When bay leaves are infused into water, it brings a minty flavor to the party. Some describe the flavor reminiscent of Christmas tree pine.
- Dried Chile Pepper: Deep red, a dried chile pepper will add color, spice and a pleasant earthy flavor to these onions. And depending on what chile pepper you choose, will dictate the level of heat to the recipe.
Bring these all together and you’ve got a wonderful flavor combination.
Step by Step Instructions
Could it get any easier?
- Slice the red onions. You can slice them into full rings or half moon shapes if you want smaller pieces. Use a sharp knife or even a mandolin. ⅛ inch slices are ideal for that perfect slight crunch.
- Break off the top of the chile pepper pod and empty out the seeds.
- Simmer the pickling mixture. In a small non-reactive saucepan, heat the vinegar, sugar, salt, seasonings and chile pepper until boiling.
- Add the onion slices and lower heat, then simmer for 30 seconds, stirring to make sure all of the onions get coated with flavor.
- Remove from heat and let the mixture cool completely. I set the timer for 30 minutes to cool and let the flavors marry.
- Store or Serve: You can either use the quick pickled onions immediately, or store in an airtight container in the refrigerator.
FAQ’s And Tips
I have been trained and by habit have always used white vinegar for any pickling project. You most certainly can substitute cider vinegar or even red wine vinegar for this recipe. It simply will bring a little more sweetness to the overall flavor.
Yes please. Boiling the vinegar along with the spice and seasoning ingredients will insure that all flavors meld together for a superior end product.
The type of dried chile pepper you choose will dictate how spicy the pickled red onions are. A Guajillo pepper, which are readily available in markets is a very mild pepper. An Ancho Pepper (dried poblano) will bring medium heat. Look for dried Pasilla Peppers for more heat. And sprinkling in a few red pepper flakes will warm things up nicely. Some slices of fresh Jalapeno Pepper works very well here and will add a pop of green color.
No, this recipe is for quick pickled refrigerator onions and not designed for a water bath method. Take a look at this recipe for canned pickled red onions.
Yes. Red onions are rich in antioxidants, vitamins and minerals. Full of fiber, they’ve been shown to boost health in many ways. Which may include fighting inflammation, boosting the immune system, as well as promoting healthy digestions. Learn more: (source) Healthier Steps.
How To Store
- Refrigerator: Once cooled, transfer onions to a clean airtight glass jar. A Mason jar works very well here. Make sure the onions are fully submerged in the pickling liquid. They’ll last for up to a month.
- Freezer: Pickled onions simply don’t freeze well.

These would be so good with fish tacos – or anything!

I love pickled onions. You got great color on yours. Thanks for the recipes. I do something similar, but you’ve added some additional spices that I think would make them even better.
I was surprised at the color too. I wonder if that dried red pepper had anything to do with it?
Yum, these wonderful onions would perk up so many different dishes. I’m imagining them piled on a rare roast beef sandwich or fish tacos.
Lovin the Roast Beef idea Cathy!
I made pickled red onions a few months ago and they were amazing. They go so well on everything – sandwiches, burgers, tacos…the list is endless. These look great!
I’m just now trying these on different foods too Joanne! Love them. As always thanks for stopping by.
Wow, I’ve never had these yummy red onions and I’ve eaten my share of Mexican food. If you think they’re the best thing since sliced bread, then you’ve convinced me that there’s no way I’m going to go on living without them.
Happy holidays Lea Ann to you and your family.

I’ve not seen these onions served in any of the Tex-mex restaurants, but we do see them at Mexican restaurants here. Hope you like them Sam. Merry Christmas to you and your family.
What a fun recipe. Mmmmm, fish tacos with these beautiful onions would be a nice change for the New Year. Whole foods, here I come!
Karen, as always thanks for stopping by and taking the time to comment. I’m already envisioning a lot of Mexican food for after the holidays.
I love the sound of these and even more…the ease. And so pretty too!
Have you ever thought of asking a chef for their recipe; I go to a couple of restaurants that will provide me with theirs; they appreciate the marketing they get if a blogger includes their recipe and where it came from. Those that resist and think we’ll never ever frequent their place again don’t quite get it!
Knowing how doesn’t mean I don’t still enjoy going out!
I ask all the time, it just seems I’m asking the wrong person. I think it’s the wait staff that doesn’t quite get it.
Oooh, we used to get the most lovely pickled onions at a local restaurant with their cheese plate. Must try this recipe… I love the color!
I love pickled onions with Raclette. Unfortunately I lost my Raclette grill in some move.
Wishing you a wonderful Christmas!
Kirsten
I think we need to go out and buy raclette grills and eat some cheese and onions. 🙂
Must. Replace. 😉
I have been looking for a pickled onion recipe!! thanks!

So good to hear from you Olga. I decided to try the heat method because of that dried chile. Needed it to steep the flavor abit. Thanks for stopping by and the comment.
