    Quick Pickled Red Onions Recipe

    Making pickled red onions couldn't be easier and only takes 15 minutes at the most! Grab your mason jar and let's get cooking!

    1. Slice the Onions. Slice your red onion into half moon slices about ⅛ inch thick using a sharp knife or a mandoline works great for super thin slices.
    2. Add your Spices. A couple chopped garlic cloves and red pepper flakes make these onions perfectly spiced!
    3. Simmer the Pickling Mixture. In a saucepan, simmer the vinegars, sugar and salt, then pour over the onions.
    4. Chill. After the mixture cools, cover tightly in a glass jar, then refrigerate until chilled.

    What To Do With Pickled Red Onions

    • Add them to tacos or carnitas. I love serving these onions with our slow cooker carnitas. Pickled onions are delicious with almost any Mexican meal- tacos, burritos, enchiladas, quesadillas, and nachos!
    • Add them to salads and bowls. Whether you're eating a fresh garden salad or a warm burrito bowl, these pickled onions are the perfect compliment of sweet & tangy flavor.
    • Load these onions into sandwiches and wraps. They’re especially delicious on chicken salad or tuna salad sandwiches.
    • Top your burgers and hotdogs. Definitely keep pickled onions on hand during the summer grilling season! 

    Variations:

    • Use different vinegar. My recipe calls for a combination of apple cider vinegar and white vinegar. But you could try red wine vinegar or white wine vinegar.
    • Add some herbs. Dried oregano, a bay leaf, fresh parsley or dill would bring lots of fresh flavor to these onions.
    • Spice them up! This recipe calls for a small amout of red pepper flakes, but you could also add in a slice of jalapeno pepper to really spice it up.

    These pickled onions will last up to a month if stored in an airtight container in the fridge!

    Ingredients

    • 1 Red Onion
    • ¼ cup White Vinegar
    • ¼ cup Apple Cider Vinegar
    • 1 cup Water
    • 1 tablespoon Sugar
    • 1½ teaspoon Salt
    • 2 cloves Garlic cut in half
    • ¼ Red Pepper Flakes optional for some spice!

    Instructions

    • Slice the top and bottom off the onion and then slice onion in half, from top to bottom. Remove the outer peel. Lay the cut surfaces of the onion onto the cutting board, and then slice into half moons using a very sharp knife.
    • Add the sliced onions, chopped garlic cloves and red pepper flakes to a glass jar- I like to use a pint mason jar.
    • In a medium saucepan, whisk together apple cider vinegar, white vinegar, sugar, and salt. Place over medium-high heat and bring mixture to a boil. Whisk until sugar and salt dissolve, then remove pan from heat.
    • Carefully pour liquid over the sliced onions and gently stir to combine. Let mixture cool at room temperature. Cover tightly with a lid and store in the refrigerator until chilled. This recipe is for refrigerator pickling only and needs to be stored in a refrigerator!
