  • 1/2 cup sugar
  • 1/2 cup white vinegar
  • 1/4 cup water
  • 2 teaspoons salt
  • 1/2 teaspoon dill weed

  4. Cover with lid and refrigerate until used.
  5. Shake the jar several times while cooling to ensure the marinade covers all onions.

Tips & Substitutions

For a sweeter flavor, consider using honey or agave syrup instead of sugar. If you're looking for a tangier taste, try apple cider vinegar in place of white vinegar. Make sure to slice the onions evenly for consistent marination. This relish can also be made with yellow onions for a milder flavor. Shake the jar every hour for the best results in flavor absorption.

Serving Suggestions

These marinated relish onions are perfect as a topping for burgers, sandwiches, or salads. They pair beautifully with the Easy Waldorf Salad for a fresh crunch. Serve them alongside grilled meats or as part of a charcuterie board. They also make a great addition to tacos and can brighten up any dish with their vibrant color and flavor.

Storage & Reheating

Store the marinated relish onions in an airtight container in the refrigerator. They will keep well for up to two weeks. There’s no need to reheat them; simply enjoy them cold straight from the jar. If you prefer a milder taste, let them sit in the marinade for an extra day before consuming.

Frequently Asked Questions

How long do the marinated onions need to sit before they are ready to eat?

Ideally, let the onions marinate for at least 24 hours before consuming. This allows the flavors to fully develop and the onions to soften. However, if you're in a hurry, they can be enjoyed after just a few hours. The longer they sit, the better they taste!

Can I use different types of onions for this recipe?

Yes, you can use different types of onions! While red onions provide a sweeter and more colorful result, yellow or white onions can also be used for a milder taste. Just keep in mind that the marinating time may vary slightly depending on the onion's thickness and type.

What dishes can I serve with marinated relish onions?

Marinated relish onions are incredibly versatile! They are excellent on burgers, sandwiches, and salads. Try them with the Southern Frankfurter Dinner for an extra zing or use them as a garnish on tacos. Their tangy flavor complements many dishes, adding a delightful crunch.
