These Dominican-style sautéed onions are tangy and flavorful, with just the right amount of crunch. They are marinated in sour orange juice, vinegar, salt, and sugar, then quickly sautéed until crisp and tender. These sautéed onions add a citrusy bite that balances the buttery mangu. 

As a child, I was never a fan of the onions on top of the mangu. They always tasted too sharp for my palate and left an aftertaste I just couldn’t get used to. But once I started cooking for myself, I began experimenting with ways to mellow them out. That’s when I learned about pickled onions and saw that sugar was often used to balance the flavor.

One day, I tried it: a little sugar, some salt, vinegar, and some sour orange juice (one of my favorite ingredients). The result was a beautifully balanced flavor: tangy, slightly sweet, and so much smoother than what I remembered as a kid.

Now, whenever I have a little extra time, I let the onions marinate for 10 to 15 minutes before sautéing. Not only does it help them absorb all that flavor, but it also reduces the time they need in the pan.

My husband, can’t get enough. He loves them over mangu, yuca, guineítos, and even roasted chicken. Honestly, these Dominican sautéed onions are one of those simple touches that elevate almost any meal.

How Your Kids Can Help

My boys don’t usually help me with this one—they say the onions hurt their eyes! But if you have brave little ones who don’t mind shedding a tear or two, there are still a few simple ways they can join in.

  2. Set up the ingredients: Kids can help by laying out the ingredients on the counter. This is great for practicing counting and following steps.

Notes

1. Onion Variety Tip
You can use either all red or all white onions, depending on what you have on hand. Red onions give a sweeter, bolder flavor, while white onions are milder.
2. Adjusting for More Tang or Sweetness
If you prefer your onions on the sour side, add a bit more vinegar or citrus. If you want a milder, sweeter taste, simply add more sugar or reduce the amount of vinegar. The balance is totally up to you.
3. Don't have sour orange?
Mix equal parts orange juice and lime juice for a similar citrusy flavor.
Storage:
Store in an airtight container in the fridge for up to 3 days. Reheat in a skillet for 1 to 2 minutes to bring back the texture.
