These pickled red onions with habaneros bring a punchy mix of tangy crunch and lively heat perfect for topping everything from tacos to eggs. Quick to make and loaded with flavor, this curtido version is a celebration of sweet-tart and spicy notes that lift any dish. Whenever I make a fresh jar, they never last more than a few days because everyone finds a new favorite way to use them.
I first threw these together when my brother gifted me a huge bag of onions and a few fiery hot habaneros from his garden. The first batch disappeared so fast that now my family asks for a double recipe every summer.
Ingredients
- Red onion: adds crunch and natural sweetness pick firm ones with tight skin for best flavor
- Habanero peppers: bring heat and color use gloves when slicing and pick ones that are firm and glossy
- Garlic: gives an extra punch of flavor go for fresh heavy cloves
- Apple cider vinegar: adds fruity depth to the brine look for raw or unfiltered for brightest taste
- White vinegar: classic tangy note pick any distilled kind for a clean pickling finish
- Fresh lime juice: brings brightness and extra acidity squeeze your own for best flavor
- Pure maple syrup: provides gentle sweetness to balance the heat and acid choose real maple not pancake syrup
- Kosher salt or pickling salt: essential for seasoning go for salt with no additives to keep brine clear
Step-by-Step Instructions
- Prep the Veggies:
- Slice the red onions thinly using a sharp knife so they absorb brine evenly. Cut habanero peppers into thin rings discarding seeds if you want less heat. Smash and peel the garlic cloves. Pile everything into a large mixing bowl and gently toss with clean hands or tongs. Pack the mixture tightly into a clean quart-size mason jar.
- Make the Brine:
- Combine apple cider vinegar white vinegar lime juice pure maple syrup and salt in a small saucepan. Set over medium heat and stir until the salt and syrup dissolve fully and the mixture just starts to simmer. This helps the flavors meld.
- Pour and Pickle:
- Carefully pour the hot brine over the onions and habaneros in the jar making sure all vegetables are completely submerged. If needed weigh them down with a clean glass or plastic item to keep them underwater.
- Cool and Store:
- Let the jar cool uncovered at room temperature until no longer warm. Screw on a tight-fitting lid and refrigerate at least 24 hours. Expect color to turn bright pink and flavors to settle in. The pickled onions will get even more flavorful after a few days.

I have always loved the color that pickled onions bring to a table but what makes this version special for me is the addition of habanero peppers. The very first time I made them my dad kept sneaking forkfuls straight from the jar and said it tasted just like the market curtido he remembered as a kid.
Storage Tips
For best results keep your pickled onions and habaneros in a glass jar with a tightly sealed lid. The flavor actually gets bolder each day as the onions soak in the brine. Refrigerated they stay perfect for about two weeks. Always use a clean fork to pull out veggies so the brine stays clear.
Ingredient Substitutions
You can swap maple syrup for honey or classic white sugar if you like things a bit sweeter or want a more traditional taste. For less heat use jalapeno or serrano peppers in place of habanero. If you run out of red onion yellow onion works in a pinch though the color will be lighter.
Serving Suggestions
These pickles shine on any taco plate burgers or even a simple cheese sandwich. Try tucking them into grain bowls shredded chicken or grilled fish tacos. I especially love them on breakfast eggs or alongside roasted root vegetables for a tangy contrast.
