Prep Time: 5 mins

Cook Time: 5 mins

Total Time: 10 mins

Yield: 2 cups

INGREDIENTS

• 1 medium red onion, sliced very thinly (a mandoline is useful for this)

• 1/2 cup water

• 1/4 cup distilled white vinegar

• 1/4 cup apple cider vinegar or more white vinegar

• 1 1/2 tablespoons maple syrup or honey (I've used hot honey and skipped the red pepper flakes)

• 1 1/2 teaspoons fine sea salt

• 1/4 teaspoon red pepper flakes (optional, for spiciness)

Instructions

1. Place the onions in a 1-pint mason jar or a similar heat-resistant container. Set the jar in the sink to catch any hot vinegar splashes later.

2. In a small saucepan, mix the water, both types of vinegar, maple syrup, salt, and pepper flakes. Heat the mixture to a gentle simmer over medium heat, then carefully pour it into the jar over the onions.

3. Use a butter knife or spoon to press the onions down into the vinegar and release any air bubbles in the jar. Allow the pickled onions to cool to room temperature (about 20 to 30 minutes), at which point they should be ready to serve.

4. Cover and store any leftover pickled onions in the refrigerator. Quick-pickled onions are best eaten within three days, but they can last for 2 to 3 weeks in the fridge.

Fun ways to use pickled red onions

Pickled red onions are not only a vibrant addition to your meals but also a versatile ingredient that can enhance a wide range of dishes with their tangy flavor and crunch. Here are several creative and enjoyable ways to incorporate pickled red onions into your culinary repertoire.

One of the simplest and most delightful ways to enjoy pickled red onions is by using them as a topping for tacos. Their bright acidity cuts through the richness of meats like carnitas or barbacoa, adding a refreshing contrast that elevates the overall flavor profile. You can also experiment by adding them to grilled fish or shrimp tacos for a zesty kick that complements the seafood beautifully.

Another fun application is in salads. Pickled red onions can transform a basic green salad into a gourmet experience. Toss them with mixed greens, avocado, and a light vinaigrette for a delicious and visually appealing dish. They can also be used in grain bowls, where their tangy bite pairs well with roasted vegetables, quinoa, or farro, creating a satisfying and nutritious meal.

For those who enjoy sandwiches or burgers, pickled red onions make an excellent condiment. They can be layered onto a classic cheeseburger or added to a hearty sandwich, such as a banh mi, where their sharpness balances the richness of the meat and creaminess of spreads. The crunchy texture of the onions also adds an appealing contrast to the softness of the bread.

Additionally, pickled red onions can serve as a delightful garnish for various dishes. Consider using them to top off a rich bowl of chili or a savory stew. Their bright color and tangy flavor can enhance the presentation and taste, making even the simplest dish feel more gourmet and thoughtfully prepared.

If you're looking to add a unique twist to breakfast, consider incorporating pickled red onions into your morning meals. They can be a surprising yet delicious addition to avocado toast (one of my favorites), providing a burst of flavor that complements the creaminess of the avocado. You can also mix them into scrambled eggs or an omelet for a zesty breakfast that will awaken your taste buds.

Finally, pickled red onions can be used in a variety of appetizers and snacks. They can be served alongside charcuterie boards, where their acidity balances the richness of cured meats and cheeses. You can also mix them into dips, such as guacamole or hummus, to add an extra layer of flavor that will impress your guests at gatherings and parties.
